Live in groups. Antelope GNU, for example, gather to huge herds to go to a distant journey to search for rich pastures. Vultures are going to flocks to deal with the prey. There are other groups with a strictest organization. Pisces are knocked into large flocks to prevent predators to hunt them, because of dense flocks it is harder to grab a separate fish.

Many birds also form large flocks to be easier to defend against predators. However, there are even more organized groups in which each animal plays its special role and performs certain functions that benefit all the community.

Family groups of animals

Inhabited in the deserts of South Africa, the meerkats are combined with several families in a group of 10-30 animals. They settle in one dwellings with other types of willer and chipmunks. Family unions are very durable, and all their members help each other in everyday life. One member of the family always monitors the attack of predators from the air, and the other is behind land predators. All family members take part in food mining and together attack the enemy.

Life in the pack

Wolves, gathering with flocks, can even attack on larger than they themselves, herbivores. Each member of the pack during the hunt performs a certain task. As a rule, quite a lot of wolves combine into the flock. However, where the herbivores are few and the wolves are forced to eat smaller animals, the flocks are small and consist only of several animals.

Recently, in moderate climatic zones there were no predators more common and dangerous than wolves. They could be found in the North American continent from Alaska to Mexico and everywhere in Europe and in Russia. Perennial persecution of these animals led to the fact that they were on the verge of extinction. But now in the Yellowstone Park in the United States, where they were delivered, you can again hear their howl. Wolves are predators that feed on almost any animals living in their territory, from small rodents to large herbivores, be it moose, deer or even sheep. The tactics of hunting wolves depends on the animal on which they hunt. Sometimes a flock cleans the terrain in search of field mice and rabbits, sometimes it is organized for a major beast with the use of various tricks. The more large mining falls on each member of the flock, the less protected by the wolves of the hunting territory. From his log house, the wolves are loud who fought the neighbors about the sizes of the flock and its strength.

Hyenal dog

Raiste wolves and dogs Guien dogs live in Savannas in the East and southern Africa. Like wolves, they are combined into flocks to hunt a GNU, gazelles and other types of antelope. They chase them in front of them until the animal fell out of his strength falls. Just like wolves, only one pair of hyenan dogs makes a young. Other rings of the dominant animal do not multiply and only help grow puppies. When the pack goes on the hunt, one of the "aunts" remains in the shelter to guard puppies.

Colonies in animals

Some animal species are going together only during mating. They organize large colonies that immediately after performing their task again decay. In such colonies, the distribution of roles does not exist. However, especially in less developed animal species, there are community-saving community, members of which behave as if they make a single living organism.

Coral polyps

Coral polyps are simply arranged organisms, each of which has only about 2 millimeters long. Together, however, they build huge limestone formations that are constantly growing. Depending on the type of corals, their colony look completely different (down to the left). Some of them have been over a thousand years. The largest coral reef In the world, a large barrier reef, also consisting of the smallest polyps, is near Australia.

Physalia

Related meduzam and corals of the Physie, also called the Portuguese boat, is not a single animal, but a group of small living organisms (zooidov). Each of them performs a specific task. Some zoodids have a mouth of the apparatus, and they are long tentacles catch a small fish that the whole colony eats. Others turn into filled bubbles and hold the whole colon at the surface of the water. The organisms that are responsible for the reproduction of organisms and egg cells.

Penguin colonies

Imperial penguins in the marriage season are going to large colonies on the ice of Antarctica. There are more than 30 giant pingguins colonies, mostly on packing ice, which for a long winter is a single monolith. Why in such a non-sensuous edge at this time, such a number of penguins is collected, it may seem a mystery. but imperial penguins Pickles are sitting in winter so that they get out to spring when a lot of food appears.

Procession of cateries

Caterpillars of hiking silkworms are going together to extract food and protect against enemies. They fly huge spider sockets in the tops of the firs and in daytime are hiding in them. At night, they crawl out of the nests and a long procession, stretching sometimes up to 10 m, led by the leader are sent in search of food.

Nests on the rocks

Olushi - widespread seabirds. Their noisy colonies are located if possible in remote places, for example, in small coastal islands. Despite the fact that these elegant birds live closely with each other, they are very aggressive and do not allow anyone to their territory, which rarely happens more of their nest. Predators are difficult to attack such huge aggressive accumulations of birds.

The largest clusters of animals

The most numerous migrations of invertebrates

Many living creatures are obvious individualists. But even at certain times of the year they make numerous migrations. And it concerns not only vertebrate animals, but also those who have no spine.

Christmas Island is located in the Indian Ocean, three hundred kilometers from Java Island. On this plumb sushi, the area of \u200b\u200bonly 130 square kilometers, lives a lot amazing beings With the most unexpected habits and features.

However, the "highlight" of the island are the famous red crabs GECARCOIDEA NATALIS. Their number in this small space is simply incredible: more than one hundred million rather large 10-centimeter creatures of the color of ripe rose hips.

They live in shallow minks in the upper part of the island. In the afternoon, they usually spend time in their asylums. And only at dawn and in the evenings, when the heat and air becomes more humid, the crabs are chosen out and proceed to the meal. They feed in mainly fallen fruits and juicy shoots. However, when this possibility falls out, they will not be refused from dead birds, and from lizard or snail.

When the most dry season comes, and it happens in winter on the island of Christmas, red crabs are closed in a mink and, shutting out the grass with a bunch of grass, flow into the hibernation for 2-3 months. They seem to disappear from the forest.

Red crabs on christmas island

But in November, when the southern summer is returned, they are chosen from the mink and for some time they refill. Accuming in the body necessary for reproduction the amount of nutrients, millions of crabs covered by the inexorable instinct of the proliferation of the genus are sent to the coast.

First, single red specks appear on forest glades and paths, which soon merge into large spots. Over time, they are combined into winding streams, and by the beginning of December, there are already whole streams of crabs flow to the ocean. It is here, on coastal stones and sand, in the tidal zone of the tide of the female will postpone caviar. After completing the final part of the journey to the sea, crabs are sent back to native places.

This "floating" multimillion armada of red crabs is a unique spectacle. Everywhere where neither see, the look rises on a moving avalanche from the red shells. Animals do not pay attention to any people or cars. And within a few days, the few beaches of Christmas Island floods a living river from red bodies.

A huge amount of small, magnitude with a bead, Chinese crabs also make migrations: they are moving in spring from the North Sea to the German River. They just two months ago left the cracker's cramor shell, but during this time they had time to get to Hamburg and Bremen, where they will remain wintering on the border of fresh and salt waters. When these crabs for two seasons will grow to five per-meantimeter length, in the spring they will leave oblique places and start moving up the river.

Antarctic krill moves huge shoals: studies have shown that in one cubic meter of water there are approximately 25 thousand individuals. And they are moving in such a huge flock of these small shrimps not randomly, but in a checker, so that the person floating ahead does not interfere with the back wave from its movement.

In gigantic flocks, often many other marine invertebrates are combined. But, probably, the largest clusters form insects, in particular, locust.

"There was a late October 1932, warm, beautiful, spring day. The weak wind blew from the southwest, and he brought trouble. From a height of 40-80 meters as if snow Blizza, the endless hordes of locust brought by the wind hit the Earth. For hours, the whole first, second and third days endlessly were their stream. Already in the near morning, all trees and bushes stood naked, the same as in winter! ..

After four weeks, the offspring of locusts was born. After another month, the invasion of the hungry flocks of Saranschuk began. Two days were enough so that there are no green leaves in the fields and gardens. Two days later, the same happened in the jungle; Even the bark on two-year trees was all eaten! "

Here is a description of the invasion of the South American locust left one of the eyewitnesses.

The hustling hordes of these rectified for many countries, especially in past centuries, became terrible economic, and a social disaster.

For example, from historical chronicles it is known that in 125 BC. e. Indecent flocks of locusts fell into the fields in the North African Roman provinces of Kerenaica and Numidia. As a result, wheat crops and barley were completely destroyed, and 800 thousand inhabitants of these countries died of hunger.

Naturally, such incredible vegetation devastation could only bring those packs of locusts in which there was a huge number of individuals. Indeed, in scientific and statistical reports on this detachment of insects, in some cases, simply fantastic figures of the number of locust are given.

So, one day, a pack was recorded that closed the sky on an area of \u200b\u200babout 250 square kilometers: according to approximate calculations, it contained about 35 billion insects, whose weight was about 50 thousand tons.

The reports on these insect describes the case when the package dropped on the ground, the locust occupied an area of \u200b\u200b4,200 square kilometers. This means that there are at least about 300-400 billion individuals in it.

And here are some more curious facts. In 1881, the inhabitants of Cyresichesed almost one and a half million tons of Saragg eggs. But in just two years, the locust postponed in the ground three times more eggs. Ten years later, the population of one of the districts of Algeria has destroyed about 560 billion eggs, about 1.5 trillion larvae and a huge amount of female females, that is, in a total of about 2.7 trillion adult locusts and its juveniles.

Of course, that individual individuals are united into such gigantic flocks, appropriate conditions are necessary. However, to establish them until 1915 scientists could not. It is at this time Russian researcher B.P. Uvarov found out one very important fact.

It turned out that for migratory locust, as well as for its other types, characterized by the presence of two phases: herd and single, each of which is characterized by characteristic morphophysiological and environmental features. That is, to become herd insect, the young locust is needed a whole complex of factors. But how many specifically these factors are required and what exactly - while scientists cannot say. Research, as they say in such cases continue.

In addition to locusts are going to huge flocks and make long migrations and other insects.

For example, dragonflies. So, one of the types of dragonflies living on the African continent regularly performs flights along the Nile River. At the same time, dragonflies fly in exactly the selected direction and any counterbasses are not enveloped, but flying away.

Often long journeys are performed and mums-hoverings. Typically, these twigs are sent to distant wanderings when the reserves of the tools are reduced in their habitats, which feed their larvae. The mass flights of these flies were marked on the mountain passes of the Pyrenean Mountains.

Very often migrate butterflies. The most visual example of such journeys of the scrapers are North American Danaida - famous monarchs. It is their migration paths that are most studied by entomologists.

These large I. bright butterflies Often B. autumn period Formed gigantic clusters and go south. One such "cloud", consisting of monarchs, landed once in the state of New Jersey, stacking its bodies with a territory of 320 kilometers and more than 5 kilometers wide. Washing the night, the next morning the butterfly went on.

When the migration of the monarchs is completed, they are going to thousands on the same trees, not paying attention to the tree that stands next to the tree.

It is curious that these butterflies have two or three generations during the summer. However, the last journey is sent last of them. And that the most striking, these young creatures that do not even have the slightest experience of distant flights are accurately flying on a specific route to the places of wintering of their ancestors.

In general, numerous accumulations of butterflies in the sky were observed repeatedly. So, their invasions are marked at 1100, 1104, 1272, 1741, 1826 and 1906. In general, more than one and a half hundred such cases are registered on Europe.

Loves to travel and butterfly reure. These scrapers often form gigantic flocks and commit distant travel, flying out thousands of kilometers. For example, in 1942, a pack of repenets, consisting of about three trillion butterflies, flew over some states of the United States!

Migration of vertebrate animals

About the huge flocks of birds, flocks of animals or shoals of fish, which at some point are broken from the hidden places and go to long-distance roads, for a long time. Animals are driven into similar travels a variety of reasons: the change of climate, hunger, the ancient instincts of the extension of the genus, etc.

Sometimes the community of migratory organisms reaches incredible numbers. Take at least fish. It is difficult to believe in it, but once in the ocean, a cant of herring was seen in the ocean, in which there were about 3,000,000 individuals.

Herring are often moved by huge shoals

The herring during migration in the polar seas can be moved, immersed by a significant depth, then be located almost at the surface itself. And the fish are moving as dense jambs that some fish, squeezed by their relatives in common packs, jump out of the water. Eyewitnesses assure that if sticking the paddle in this jamb, it will remain vertically.

Huge shoals move and pink salmon going to spawning in the river.

"With solar and quiet weather, the Soviet researcher MF writes. Pravdin, - from the middle of the river there is an extraordinary noise to the shore. The population rushed to the shore, and here everyone was admired for a long time, as a huge cant of humpbacks with strong noise and with unlimited jumping of individual fish went up the river, as if the new river broke into the river Greater. The strip of noisy fish has stretched at least as on the mile, so without exaggeration we can assume that there was not one million fish in this jamb. "

Sometimes in huge flocks on the surface of the water surface and sea snakes. So, in 1932, a huge number of random woven serpentine bodies was observed in the Malaccian Strait. Living tape, which was formed by reptiles, with a width of three meters stretched approximately 110 kilometers. In this accumulation was about about a million snakes. What was the reason for such a mass accumulation of snakes? - It's hard to let. But, most likely, it was a marriage gathering.

Huge flocks form and birds, especially during the autumn and spring migrations. Often there are hundreds of thousands of individuals. This is especially true of small birds. However, it is unlikely that the records will be broken, which the American wandering pigeons installed in the previous century.

These birds lived in the United States and South Canada. When a flock of these birds appeared in the sky, it became so dark, as if the early twilight was coming. And it lasted this "eclipse" sometimes for quite a long time, since the birds have closed the entire sky from the edge to the edge for several hours.

American ornithologist Wilson describes a flock of pigeons, which stretched 360 kilometers. According to the approximate calculations of the zoologist, there were about 2,230,000,000 pigeons in this bird community. Another ornithologist - Odubon - reports about the flock of these birds, which united approximately 1,115,000,000 individuals!

But not only birds are going to huge flocks. In the migration period, gigantic communities form many mammals. So, once on Taimyr from the helicopter, a flock of deer with a number of 300 thousand individuals was noticed.

However, this is not such a big flock of wild mammals. Once on the American north, the flock of caribou, numbering millions of individuals. For example, one flock for four days of a continuous avalanche moved past amazed hunters. Subsequently, eyewitnesses of this "march-throw" of animals said that it was about twenty-five million deer in herd.

In the huge herds in search of pastures, Antelope Gnu, inhabiting in Tanzania gather. Animals are moved by an infinite flow, which sometimes occurs to one and a half million individuals.

And in 1929, one traveler met in Calahari a mixed herd of GNU and Zebras, in which, according to him, was about ten million animals!

Once on the endless expanses of the steppes and semi-deserts of South Africa, the so-called mountain hits were widespread. IN rainy seasonWhen the Earth was covered with abundant greens, and rivers and lakes were filled with lively moisture, these animals were embarrassed from pasture to pasture. And so it lasted until drought fell.

Then the mountain hits left their native places and, gathering in huge herds, moved the savannah sovereed to the merciless sun in search of food and water. Some of these stades were up to a million animals.

Sometimes hunger, and perhaps, and some internal factors, are forced to be knocked into huge "hordes" and protein. So, at the end of the XIX century, the city of Nizhny Tagil was unprecedented by the invasion of these animals.

"The proteins walked alone," writes the famous Russian bibliographer and writer N.A. Rubakin, - that heaps, they went straight and straight, fled down the streets, led across the fences and hedges, climbed into the houses, filled the yards, jumped along the roofs. "

Proteins moved, not paying attention to any people nor the dogs who bred them in huge quantities. People also beat them a lot. And despite the danger, they still went. The invasion lasted until the evening. At night, animals were hidden, but as soon as the sky was glad, they continued their way. Three days of the protein were deposited by Tagil.

The city has flowed fast and wide chusovaya river. But she did not stop the countless mass of animals. They rushed into cold waves and, torn up the tails, sailed to another shore.

Already later it turned out that only a small part of the protein came to Nizhny Tagil. Their majority passed in eight kilometers from the city. In this Belichy Armada, several million individuals were supposed.

Mass migration marches are accomplished amazing, weighing from 70 to 100 grams, animals living in the Arctic tundra. And although these are not such rare mammals, it is not less to see them only in singles.

And this is due to the fact that the number of lemmings changes periodically, and in completely incredible limits: three or four years of animals in the afternoon do not find the fire, and then suddenly - "demographic explosion". Lemmings are sissed everywhere, as if fish in the lowroad. Riddle? Sure! However, as well as their sudden marchs, when lemmings suddenly gather in huge flocks and go to distant travel. Moreover, these peace-loving lumps of wool turn into very aggressive rodents.

Many legends are associated with these legend travels. For example, the myth of the collective suicide of rodents. Allegedly, when the number of lemmings increases, they, having rushing into huge flocks, head to the sea and rush together with a cliff into the punching. Today, biologists are confident: lemming suicide is fiction, although, perhaps, some unknown people are accomplished and provoke this phenomenon.

But the fact that the lemmings are not at all afraid of water, is true. At least it has long been noticed that during the migration of animals, neither cold rapid rivers, nor wide lakes. They sail two or three kilometers without much effort and, choosing to land, confidently continue their trip to the unknown. But so floating these tiny creatures only in calm water: when the wind flies and the waves rose, rodents are drown. By the way, it should be borne in mind that in this case we are talking about Norwegian lemmings, in contrast to which Canadian, for example, do not migrate at all.

And there are Norwegian lemmings exclusively in Scandinavia and on the Kola Peninsula, where under the three-meter layer and winter, being almost completely safe, as the enemies are difficult to reach their nests.

Lemmings do not fall into winter hibernation and therefore multiply even in the cold. The smell of females, ready to give birth to offspring, males feel at a distance of more than a hundred meters. And as soon as they catch him, right away from all sides, they rush to her and begin a fierce struggle for the right of possession of the "bride."

However, lucky will not long: after a short pairing, the female immediately drives him out for the threshold of the hole. And at the end of February she appears the first brood, in which there are only three or four young. But in summer, their twice is greater, and the female can give birth during this period.

But lemmings are behaved so much during the usual population number. When the animals become much, their character changes dramatically. The animals are going to the flocks and begin to migrate. In search of feed, they overcome distances in hundreds of kilometers. In these campaigns, the tundra females are experiencing such stress that they could not get pregnant.

In the behavior of the lemming, aggressiveness appears: putting on the rear legs, they are with a fierce peak and grunts rush to everything that moves - whether man, animal or car. The bite of angry rodent is very painful.

The lemmings are terribly voracious. The reason for such an appetite is in poverty of the diet, consisting mainly of moss and various herbs. Other food for rodents in the tundra is not. Two thirds of the lemmings eaten is simply "ballast", which is not even digested. It is in the "menu" of animals Some scientists see the regulator of the mysterious explosions of the number of lemming. The lack of feed delays the growth and ripening of lemmings - broods become smaller. When a lot of herbs and moss, the number of lemmings is rapidly increasing. Other zoologists believe that the number of lemming depends on the number of their main enemies - the ermine, the White Owl and the Polar Liser.

There is another hypothesis that binds the takeoffs of the lemming population with the protection mechanisms in the tundra plants of cotton and the sources that make up the basis of their diet. These plants synthesize special substances that block the effect of the lemming digestive juice. But while the animals absorb cotton and the sump moderately, the plants do not distinguish the poison in critical quantities.

When lemmings eat everything around, it happens when the number increases in tens and hundreds of times, the plants begin to synthesize the blockers substances continuously. As a result, the lemmings are unable to digest eaten grass.

In response, the body of the lemming begins to produce more and more gastric juice and as a result is depleted much faster than from ordinary hunger. And the more lemming eats, the hungry becomes. The result of a similar failure is, according to a number of scientists, mass migrations.

The longest migrations

In addition to the numerous individuals in one migration pack, the human imagination and the length of the path are struggling, which moves the animals sent to the distant journey.

Take, for example, polar stuff. These small white birds with "beretics" on the master's head nest in the north of Canada, Alaska, Siberia and Europe, as well as in Greenland. Sometimes they will settle so close to the pool that during surgery from the sky, snow flakes fall. And then the birds to protect the chicks from the cold, around the nests are heated in a heap of snow.

With the onset of autumn, the tasks suddenly leave the hurry places and go to the warm edges. Although you call the places where they hold the path, warm is also quite difficult, as these birds are winter. Antarctica.

Twice a year, polar masks fly from Canadian tundra to Antarctica and back

If the crags fly from Canada and Greenland, then their route runs first through Europe. British islands are found with Siberian and European relatives, and together along the coast of France and Portugal move to Africa. Reaching Senegal or Guinea, flocks of Krachek are divided into two sleeves: some fly to the fiery ground, others in the cold sea Ross and Weddell.

Twice a year, these irrepressible birds from the Canadian tundra to Antarctica will fly apart 19 thousand kilometers, that is, their way on both sides is equal to around the tight travel around the equator - almost 40 thousand kilometers.

Even longer flights make crags living on Chukotka. First, they fly along the Siberian coast of the Ice Ocean west. Then, rebuilding Scandinavia, turn to the shores african continent. And only after that a long zigzag flight rushed to Antarctica. At the same time, birds fly in one direction 30 thousand kilometers, and the same - in the opposite. And that's what is curious about this unique flight: the colt, it turns out, fly over cold oceanic currentswhich are more different living things. Its they catch it, rushing in cold waters from a height. By the way, on the same, however, the water routes are moving and used whales.

Wilson's petrel also envelopes the Earth from the pole to the pole, only in the opposite direction. Winter he spends near Northern Scotland and Newfoundland, and chicks grows in the harsh climate of Antarctic Islands.

Famous swallows and haircuts also make considerable flights: their length is about ten thousand kilometers. At the same time, its air "march-throws" haircuts are nonsense: the birds are not only quenched in flight hunger and thirst, but even sleep on the fly.

But the church of Gagars in the distant path goes away. And they float north, although they run away from the winter. Paradox? Although! The fact is that by adding on the rivers of Siberia to the northern coast of the island of Taimyr, birds are included in the Kara Sea, where they immediately turn to the West. Then, coming to the Karian gate, go to the Barents Sea, which crosses, rich Scandinavia. After that throw, they fall into the North Sea, and only then to the West Baltic, where they spend the wintering. A decent path of the path overcome birds - 6 thousand kilometers. And almost all the time climb.

The unique result demonstrates the rzhanks that live in Alaska and Chukotka, but winter in Hawaii. There is no sushi between these two points of the land, but the birds over twenty-two hours of a futury flight overcome this distance equal to three thousand kilometers!

A striking on the length of migration makes and clumsy on appearance of sea seals, the reproduction of which occurs on the islands of profit and commander. As soon as the animals will grow up young, cats with a team go to swim in the south-samp direction, sometimes reaching even to Japan, and the "profitable" cats rush to the southeast to California. In this case, the length of the path whipped by animals in both ends is approximately 10,000 kilometers.

Usually, with the painfulness of coral reefs and the diversity of its inhabitants, in the waters open Ocean Tropics of living organisms are very small, since these waters are poor feeding resources. For this reason, in these places, there are practically no huge messenger whales that feed on small crustaceans - Cream.

And only the Caribbean Sea, as well as the sea around Galapagos Islands Russed by Plankton and fish, and such an abundant feed base lies here many cetaceans: dolphins, coushlots, blue and humpback whales.

They sail into these abundant foods of places from the polar seas, overcoming the sometimes distance of 6400 and more kilometers. And during such a long journey, they almost do not eat. Although some females during this period are in a state of pregnancy or feed the milk newborns.

Careful and perennial studies of sea turtles surprised scientists with many of their behavioral features. For example, these reptiles are truly ambitious at their length oceanic travel. So, between 2006 and the beginning of 2008, the satellite constantly registered the movement of leathery turtles from the places of their nesting on the beaches of Papua to the coast of the American state of Oregon, that is, to the other side of the planet. This journey took 647 days. And during this time, the animals overcame the distance equal to 20,560 kilometers.

During migrations, many thousand kilometers leave and some fish. So, the challenge climbs up the Yukon River by 3.5 thousand kilometers. Flowing fish at a speed of twenty, and in certain periods and fifty kilometers per day.

But if salmon fish for spawning float into their native rivers, then snipe-like eels, on the contrary, from rivers - to the sea, overcoming a distance of 6,000 kilometers. And they float in one place in the World Ocean - in Sargassovo Sea. It is here they droop caviar. Adult fish after spawning die, and back in the river of the year after three returns young.

Of course, such a huge length of migrations of large animals is amazing. But even greater surprise cause migration of insects, overcoming sometimes not hundreds, and thousands of kilometers through the air, flying over the endless seas and the highest mountains.

For example, a pack of locusts, originating in Africa, in a week may be in Europe, overcoming during this time almost two and a half thousand kilometers.

Butterfly-monarchs, inhabiting in the south-east of Canada, fly to wintering in Mexico, leaving the path of almost three thousand kilometers.

Of course, mentioning all the "round-world" travels of fish, birds, animals or insects are almost impossible, but also this information is enough to understand how long the distance overcome by many alive organisms during migrations.

Record invertebrate colonies

Often, single species of animals are combined into the community, and in fairly numerous. In general, the presence of colonial life forms is characteristic of many types and classes of invertebrate animals: ranging from the simplest and ending with spiders and insects. True, in most cases in these communities the number of individuals is small.

In addition, even if such communities are numerous, they often represent only a binding of tens, hundreds or thousands of individuals on a small section of the earth's surface or at the bottom of the reservoir.

Of course, about all the organisms that live in big colonies or communities, it is almost impossible to tell in a small essay, so we will dwell only on some, in our opinion, the most interesting.

For example, on radolaria. The fact that these unicellites are united in colonies, scientists knew for a long time. But they did not see the true dimensions of these communities. However, in the warm waters of the Floridian flow, oceanologists sometimes stumbled into colonies that had a length of several centimeters to a meter and more. One can only assume how many millions of single-celled beings, a diameter in the hundredths of a millimeter, was in such huge communities.

But such giant colonies, of course, feed in accordance with their sizes. In their diet, conventional components are phytoplankton, molluscs, single radiolearies, small hydraulication and other organisms. As a source of food, they use photosynthesis products of their symbiontes, as well as themselves.

As it turned out, the colonies of radiolearies are a rather complicated biological structure. Thus, observations showed that the colonies are monitored over algae symbiontes. Their arrangement varies depending on the light mode: in the dark, algae are collected around the central capsule, they are evenly distributed in the light of the colony throughout the shapeless mass. And they carry out radolaries. This movement of symbiontes with their own pseudopodies.

Various types of radilation

At the ends of some colonies, especially those that are actively feed on molluscs, there are special formations, where they are concentrated, and then derived from the colony of the shell of the eaten larvae. Special pseudopods collected in bundles are collecting and transporting residues.

Huge colony sizes form some terrestrial animals. The emergence of such structures is associated with the reproduction of these animals by killing, when as a result of these processes from old polyps form new, which leads to an increase in the size of the colony. And since many corals colonies grow in all directions, sometimes they reach very impressive sizes: for example, some types of Porites have a volume of more than 100 cubic meters. If we consider that the size of one polyp is approximately 1-1.5 millimeters, then in such a volume there are at least tens of millions of polyps. And such a colony-giant appears as a result of the boring of the entire single polypa.

Form colonies and some types of flavors. But the community of these animals is small: they combine only 2500-3000 individuals.

Another group of animals, prone to the formation of colonies, - Msanka. And in general, in most of its own colonial organisms. And their communities are often consisting of a huge number of individuals. For example, a piece of flustrafoliacea colony weighing 1 gram contains about 1330 individual organisms. This msanka is growing sometimes up to several meters, reaching kilogram weight.

And some types of Msnok covers their bodies of the area over 200 square meters. At the same time, the height of the colonies reaches sometimes 12 centimeters.

It is known about the existence of colonies and in such individualists as spiders. Puchis communities are registered with spiders of Theridion Nigroannulatum. They live in nests, in which several hundred, ATO and thousands of individuals are sometimes going.

When spiders hunt, from their dwellings they stretch the threads to leaves and are waiting for the appearance of the victim. While everything seems everything happens according to the usual spider script. But further spiders show something new and original.

At that moment, when the insect concerns the threads and falls into the trap, a large group of spiders pop up and tightens the victim by sticking cobweb, while also injected her a fairing portion of poison.

Moreover, hunting, spiders contact each other not only during the attack on the sacrifice, but then. For example, if the extraction is too heavy, then they drag it, flowing each other in turn.

But the attack on the sacrifice the agreed actions of spiders are not limited. When this Vataga of the octopov hunters will drag the housing in the dwelling, the principles of collectivism are also observed here: each of the inhabitants of the nest receives its portion of food.

But this is not all the "oddities" of this species.

Speaking about thousands of individuals in one colony, it should be emphasized that it is rare exceptions. As a rule, only a few dozen individuals live in one nest. If the community is really consisting of many and many hundred spiders, then sometimes such huge settlements on the unknown reason for the reason suddenly diluted in a few days are scattered into small groups. By the way, this species was discovered in 1884. Zoologists learned about his own social structure only over a hundred years.

South African spiders from the genus Stegodifus also prefer to live in large communities. They together and the hostel, the bag is similar, build, and the casual threads from him stretch along the parties, and they throw together. Moreover, even dinner at one table without "moving and fighting".

Moreover, these spiders are so hospitable that even the caterpillars of some butterflies do not drive, do not kill, but generously suffer, accurately lazy households. But the caterpillars do not remain. Picking up their spiders, they are thus watching the cleanliness in the spray community. Evaluating such generosity and trust, butterflies that appeared from the caterpillars, do not hurry to leave benevolent stegodifus.

Inhabit public spiders usually warm areas of the globe. They can be found in the forests of Amazonia, in Africa and in Australia, separate species inhabit Mexico and in India.

But among insects there are several groups that other life, except life in large communities, are unlikely to represent. These winged creatures are primarily public insects: bees, bumblebees, many species, ants, termites. And the most largest colony forms the last two groups.

So, in the small volume of anthills there are from 100 to 200 thousand insects, in the middle - 400-700 thousand. And in the gigantic nests of red forest ants and American-leaf-labeling, the genus ATTA often numbered about five million insects.

However, none of the insects, probably, in the number of individuals in the colony, will not compare with termites. But since different types of termites have different fecundity, the number of population in one meter - the dwelling of these insects - can differ significantly. Based on the fruitiness of the uterus, you can approximately calculate the population of one family of termites.

So, the uterus of the tourism termit carries approximately 100 eggs per hour, and the Termes Bellicosus female puts 30,000 eggs per day, and a year - about ten million nine hundred and fifty thousand.

At the same time, the "production" of eggs it is engaged in continuously day and night. Given the same size of the fracthers reaching 6, 10 and even 12 meters in height, it can be assumed with a high degree of confidence that there are not one million individuals in them.

However, the competence of ants and termites in the struggle for the pedestal can be one of the types of crustaceans - a deserted moc., Which in the desert, on favorable areas for living, forms huge colonies. And although each family, in general, land plots are small - the size of the palm, but the territory has fallen into love with mocity occupies a huge area inhabited by several millions of these strange crustaceans.

Curious family-colonial relations exist in Caribbean, or royal, shrimp-clutches, who live in almost all major sponges on the barrier reef. Moreover, each of them is from 150 to 300 racks. But at the same time, in each "family" there is only one prolific female. And the rest of its inhabitants are represented by young and males, one of which, if the "queen" suddenly perbs probably turns into a female. That is, these crustaceans, like bees, ants and termites, can be called social animals with full right. If we talk about the quantitative composition of all shrimp-shortcuts living in sponges of the barrier reef, then their number is even difficult to imagine: at least they are not one million.

Large spinal colonies

Many types of vertebrates for breeding period and in places with abundant food resources are collected in huge communities. But among these organisms, species, for a long time living in large colonies, not so much.

Among the fish, an example of such a community can be called several types of tubular acne. These snake-shaped fish have a middle length about 50 centimeters. They live on the seabed in special, the same pipe-like nera themselves. The walls of these structures are so tightly strengthened with a sticky substance that produce skin glands of acne, which is never collapsed, although the fish pulls her body into a mink fast and sharp movement.

When everything is calm around, the lower part of the eel is hidden in the mink, while the upper sticks over the bottom surface. Eel at this time smoothly swinging, capturing small organisms. But as soon as the threat to the life of the fish, they immediately hide in their asylums.

Ninks of acne are usually one of the other at a distance of about twenty -stessing centimeters. At the same time, the area occupied by settlements of these fish is calculated by many hundred square meters. This means that several tens of thousands of acne can be located on such an area.

Lichwood river Mingo. - Pescokhiki

Almost the same way of lifestyle, like tubular acne, lead the larvae of river mine ebes-fork. They, too, are buried in the orstate bottom, cementing the walls of their mink by sticky discharge. At the same time, pecked places will settle so tightly, "that the bottom of the river shakes, if you look at the top, looks like a sieve: everything is in small holes." You can not doubt that tens of thousands of larvae live in such colonies.

Large communities are going sometimes birds. Probably, everyone heard about bird bazaars where there are hundreds of thousands and even millions of chaps, krachek, penguins, albatrosov, oleshi. Thus, in some nesting colonies, Penguin Adeli gathers several tens of thousands of birds, and on the island of Ross, one time existed a colony in which he had to half a million individuals.

The famous flamingos dwelling in Eastern and South Africa are going to very numerous groups. Sometimes there are several million birds in their "companies". Often such colonies can be observed on the East African Great Lakes. However, there are no special friendship in these birds. Sometimes, however, they big companies Trying to expel predators from their possessions.

However, some species of birds live although small, but real hostels, where both shelter and care are common. So, South American cucks from the genus Ani are gathering a small company and build a large deep nest. Then all the females who participated in construction work are postponing in this nest eggs. Usually eggs 15-20, but sometimes they are recruited even about fifty. In the accidents of eggs, several birds are also involved at the same time, which periodically change each other on the masonry. When chicks appear on the light, they also feed them with the whole world. Moreover, males work along with females.

Unique colonies in the settlers of African Savannan - white buffalo birds. They build a lot of nests in the crown of one tree, between which spiny branches are placed. The result is a common "house", in which the entrances and individual "apartments" are located below. At the same time, such a "communal apartment" can have 2-3 meters in diameter.

The collective nests of public weaver are also achieved. First, several birds find a suitable tree and begin to build a roof from branches and dry grass on it. Then, inside this frame, each pair of monogamous birds builds its own nesting chamber. All nest resembles an abandoned sane tree, penetrated by the downstreams directed downwards.

Year after year, the birds are completing their nest, as a result of which the age of some nests reaches more than a hundred years. At the same time, there are up to 300 socket cameras in such jacks. And the size of these nests is impressive. For example, the length of one of such structures was 7 meters, width - 5 and height - 3 meters.

Build collective nests and parrots monks. They also have "at home" with common roofBut with separate rooms for each couple.

From our birds, many thousands of colonies are characteristic of the grits, corners, docks, starling.

For many cities of their settlements are a real disaster. Large accumulations form often herons and cormorants. Especially close to artificial reservoirs.

For example, on large fish farms, the number of cormorants is calculated by thousands.

From mammals, probably, the most numerous colonies are characteristic of meadow dogs. Externally, these half-meter animals are similar to the inhabitants of the steppes - Surkov, although they are lit like dogs. Each family has its own separate residential house-nora, outside connected with neighboring housing narrow paths.

Now these rodents have dubbed. And before they lived with the colonies of incredible sizes. So, in the 60s of the XIX century in american state Texas discovered the colony meadow dogsin which there were approximately 400 million animals. According to the occupied area, this settlement was twice more territory of the current Holland.

Previously, the crumbs were settled by large colonies. But the invasion of man in the steppe significantly reduced their number. Nevertheless, in our time there are numerous settlements of these animals. For example, in the Melok district, the colony of Surkov has about 8,000 holes. This means that in the colony in the peak of its development can dwell by several tens of thousands of animals.

Zoologists have information about the huge colonies of bats. For example, quite recently, in the south, the Philippines in the area of \u200b\u200bMindanao found a cave in which about 1.8 million weldows breed and breed.

The attraction of the American city Austin is a huge colony of bats living under the bridge. This settlement of the winged mammals has about one and a half million.

Near the Mexican city of San Antonio is also a wonderful place: this is a visit, which for folds, or bulldog, manochable is a kind of maternity home. For a period of reproduction, up to 10 million females from many Corners of Mexico are flowing. And some of them, to be in this place, have to overcome a distance of 1800 kilometers.

Each female usually gives birth to one young. As a result, the density of kids in this underground grotto reaches 3000 per 1 square meter of the ceiling. These are the most populated bird nursery in the world. And it's amazing: Returning from the night hunting, the mother approximately 85% of cases finds and feeds his cub. And to do it, it is probably helped by a great memory, surprisingly acute hearing and an excellent sense of smell.

By the way, scientists have long been interested in the question of how managed to feed the multi-million flocks of bats that live in some America's caves. After all, a colony of 10 million individuals eats about 100 tons of insects per day. In the end, they do not feed the same air. Then what?

And finally the mystery was resolved. It turned out that these mice feed. At an altitude of 2-3 kilometers from the ground. It would seem that this is a clear paradox: after all, it is very difficult to assume that such an abundance of insects can be found daily on such huge altitudes.

But the fact is that there are huge flocks of butterflies from Mexico on such heights. And they make such flights every day. And bats, "catching" this amazing pattern, in their behavior began to follow it. Is it just like easy?

But naked farmer is a mammal living in Africa, although it does not differ in the numerous colonies, but has a number of other curious features. For example, these animals are almost completely devoid of hair cover. Live underground, where at a depth of about two meters dig long, four centimeters in diameter, holes connecting into one general farming Nest cameras, restrooms and feed plots. The length of these tunnels is 3-5 kilometers, and the annual Earth emissions during digging are 3-4 tons. In this underground kingdom, it sometimes lives to 250 individuals.

But the most curious is not even this. It is much more interesting that the colonies of naked farms are built on the same principle as the colonies of public insects: they have a division of labor, as well as one constantly puced uterus.

Dangerous animal immigrants

Above already described about those groups and types of animals, which constantly live with numerous colonies or are going to huge herds, flocks or shoals during reproduction or when they migrate in search of the best habitats.

But outside of our attention, another group of organisms remained, which gave a record population outbreaks after a person moved to new places for them, where they did not meet the limiting environmental factors.

1853 year. The American scientist Aza Fitch on the leaves of the grapes find a tiny insect, which turned out to be a toe of an unknown look. Subsequently, in the registers of zoological science, it was listed under the name Phylloxera Vastatrix, or, simply speaking, Filloxers.

After 15 years, this insect suddenly gave itself to know in France. A tiny creature was set on the roots of the grape vines, all the juices sucking it, and the bush died. During this sudden attack in France, Filloxer reduced two and a half million acres of vineyards. The damage caused by the economy of France Filloxus was incredible: ten billion golden francs!

Grape leaf struck by Filoxer

But not only France occupied a modest TLL. In 1869, she already hosted in the vicinity of Geneva, then moved to Germany and Austria. And in 1880 she visited the Crimea, Kuban, Bessarabia, Tashkent.

Changed the situation with the vineyards of a small tick, which by thousands destroyed the phylloxer. These crumbs from America brought to Europe and released on the vineyards. They are too. Save the position.

No less dizzying success in the development of the European continent, another "American" was achieved - the Colorado Beetle. Indeed, his homeland is the West of North America, where it is before the appearance of cultural potatoes dwell on the wild plants of the Polenic family.

But in 1865, in 1865, it seems to be no noticeable bug appeared on the Potato Fields of Colorado, and at the same time caused them serious damage. At the place of his homeland, he received the present name. To prevent its further distribution, appropriate sanitary measures were taken. But they did not help: Soon the pest was a confident "taught" not only in North America, but also appeared in Europe. He was trying to restrain him with all available means. But the final victory of a man over the Colorado Beetles was prevented by the First World War.

At this time, Europeans were not to sanitary control, and soon the dangerous pest was reliably "swallowed" in the French coast. Then, despite the efforts of the quarantine services, the Colorado Beetle, manifesting non-life activity, quickly spread throughout the countries of Central Europe.

In 1933, he appeared in England. Three years later, housing in the fields of Belgium, Holland, Switzerland. Then demonstrated his non-commodity appetite in Czechoslovakia, Poland, Hungary.

Where do the biggest and most poisonous snakes live? There is a saying: "The eyes of the eye is great." The same can be said about all the legends that exist about snakes. So, they say that there are huge snakes somewhere, length up to 20 or more meters. But no one is actually

About the huge flocks of birds, flocks of animals or shoals of fish, which at some point are broken from the hidden places and go to long-distance roads, for a long time. Animals are driven into similar travels a variety of reasons: the change of climate, hunger, the ancient instincts of the extension of the genus, etc.

Sometimes the community of migratory organisms reaches incredible numbers. Take at least fish. It is difficult to believe in it, but once in the ocean, a cant of herring was seen in the ocean, in which there were about 3,000,000 individuals.

The herring during migration in the polar seas can be moved, immersed by a significant depth, then be located almost at the surface itself. And the fish are moving as dense jambs that some fish, squeezed by their relatives in common packs, jump out of the water. Eyewitnesses assure that if sticking the paddle in this jamb, it will remain vertically.

Huge shoals move and pink salmon going to spawning in the river.

"With solar and quiet weather, the Soviet researcher MF writes. Pravdin, - from the middle of the river there is an extraordinary noise to the shore. The population rushed to the shore, and here everyone was admired for a long time, as a huge cant of humpbacks with strong noise and with unlimited jumping of individual fish went up the river, as if the new river broke into the river Greater. The strip of noisy fish has stretched at least as on the mile, so without exaggeration we can assume that there was not one million fish in this jamb. "

Sometimes marine snakes are going to huge flocks on the surface of the water surface. So, in 1932, a huge number of random woven serpentine bodies was observed in the Malaccian Strait. Living tape, which was formed by reptiles, with a width of three meters stretched approximately 110 kilometers. In this accumulation was about about a million snakes. What was the reason for such a mass accumulation of snakes? - It's hard to let. But, most likely, it was a marriage gathering.

Huge flocks form and birds, especially during the autumn and spring migrations. Often there are hundreds of thousands of individuals. This is especially true of small birds. However, it is unlikely that the records will be broken, which the American wandering pigeons installed in the previous century.

These birds lived in the United States and South Canada. When a flock of these birds appeared in the sky, it became so dark, as if the early twilight was coming. And it lasted this "eclipse" sometimes for quite a long time, since the birds have closed the entire sky from the edge to the edge for several hours.

American ornithologist Wilson describes a flock of pigeons, which stretched 360 kilometers. According to the approximate calculations of the zoologist, there were about 2,230,000,000 pigeons in this bird community. Another ornithologist - Odubon - reports about the flock of these birds, which united approximately 1,115,000,000 individuals!

But not only birds are going to huge flocks. In the migration period, gigantic communities form many mammals. So, once on Taimyr from the helicopter, a flock of deer with a number of 300 thousand individuals was noticed.

However, this is not such a big flock of wild mammals. Once on the American north, the flock of caribou, numbering millions of individuals. For example, one flock for four days of a continuous avalanche moved past amazed hunters. Subsequently, eyewitnesses of this "march-throw" of animals said that it was about twenty-five million deer in herd.

In the huge herds in search of pastures, Antelope Gnu, inhabiting in Tanzania gather. Animals are moved by an infinite flow, which sometimes occurs to one and a half million individuals.

And in 1929, one traveler met in Calahari a mixed herd of GNU and Zebras, in which, according to him, was about ten million animals!

Once on the endless expanses of the steppes and semi-deserts of South Africa, the so-called mountain hits were widespread. On the rainy season, when the Earth was covered with abundant greens, and rivers and lakes were filled with a lifeful moisture, these animals were nomaded from pasture to pasture. And so it lasted until drought fell.

Then the mountain hits left their native places and, gathering in huge herds, moved the savannah sovereed to the merciless sun in search of food and water. Some of these stades were up to a million animals.

Sometimes hunger, and perhaps, and some internal factors, are forced to be knocked into huge "hordes" and protein. So, at the end of the XIX century, the city of Nizhny Tagil was unprecedented by the invasion of these animals.

"The proteins walked alone," writes the famous Russian bibliographer and writer N.A. Rubakin, - that heaps, they went straight and straight, fled down the streets, led across the fences and hedges, climbed into the houses, filled the yards, jumped along the roofs. "

Proteins moved, not paying attention to any people nor the dogs that bang them in a huge amount. People also beat them a lot. And despite the danger, they still went. The invasion lasted until the evening. At night, animals were hidden, but as soon as the sky was glad, they continued their way. Three days of the protein were deposited by Tagil.

The city has flowed fast and wide chusovaya river. But she did not stop the countless mass of animals. They rushed into cold waves and, torn up the tails, sailed to another shore.

Already later it turned out that only a small part of the protein came to Nizhny Tagil. Their majority passed in eight kilometers from the city. In this Belichy Armada, several million individuals were supposed.

Mass migration marches are accomplished amazing, weighing from 70 to 100 grams, animals living in the Arctic tundra. And although these are not such rare mammals, it is not less to see them only in singles.

And this is due to the fact that the number of lemmings changes periodically, and in completely incredible limits: three or four years of animals in the afternoon do not find the fire, and then suddenly - "demographic explosion". Lemmings are sissed everywhere, as if fish in the lowroad. Riddle? Sure! However, as well as their sudden marchs, when lemmings suddenly gather in huge flocks and go to distant travel. Moreover, these peace-loving lumps of wool turn into very aggressive rodents.

Many legends are associated with these legend travels. For example, the myth of the collective suicide of rodents. Allegedly, when the number of lemmings increases, they, having rushing into huge flocks, head to the sea and rush together with a cliff into the punching. Today, biologists are confident: lemming suicide is fiction, although, perhaps, some unknown people are accomplished and provoke this phenomenon.

But the fact that the lemmings are not at all afraid of water, is true. At least it has long been noticed that during the migration of animals, neither cold rapid rivers, nor wide lakes. They sail two or three kilometers without much effort and, choosing to land, confidently continue their trip to the unknown. But so floating these tiny creatures only in calm water: when the wind flies and the waves rose, rodents are drown. By the way, it should be borne in mind that in this case we are talking about Norwegian lemmings, in contrast to which Canadian, for example, do not migrate at all.

And there are Norwegian lemmings exclusively in Scandinavia and on the Kola Peninsula, where under the three-meter layer and winter, being almost completely safe, as the enemies are difficult to reach their nests.

Lemmings do not fall into winter hibernation and therefore multiply even in the cold. The smell of females, ready to give birth to offspring, males feel at a distance of more than a hundred meters. And as soon as they catch him, right away from all sides, they rush to her and begin a fierce struggle for the right of possession of the "bride."

However, lucky will not long: after a short pairing, the female immediately drives him out for the threshold of the hole. And at the end of February she appears the first brood, in which there are only three or four young. But in summer, their twice is greater, and the female can give birth during this period.

But lemmings are behaved so much during the usual population number. When the animals become much, their character changes dramatically. The animals are going to the flocks and begin to migrate. In search of feed, they overcome distances in hundreds of kilometers. In these campaigns, the tundra females are experiencing such stress that they could not get pregnant.

In the behavior of the lemming, aggressiveness appears: putting on the rear legs, they are with a fierce peak and grunts rush to everything that moves - whether man, animal or car. The bite of angry rodent is very painful.

The lemmings are terribly voracious. The reason for such an appetite is in poverty of the diet, consisting mainly of moss and various herbs. Other food for rodents in the tundra is not. Two thirds of the lemmings eaten is simply "ballast", which is not even digested. It is in the "menu" of animals Some scientists see the regulator of the mysterious explosions of the number of lemming. The lack of feed delays the growth and ripening of lemmings - broods become smaller. When a lot of herbs and moss, the number of lemmings is rapidly increasing. Other zoologists believe that the number of lemming depends on the number of their main enemies - the ermine, the White Owl and the Polar Liser.

There is another hypothesis that binds the takeoffs of the lemming population with the protection mechanisms in the tundra plants of cotton and the sources that make up the basis of their diet. These plants synthesize special substances that block the effect of the lemming digestive juice. But while the animals absorb cotton and the sump moderately, the plants do not distinguish the poison in critical quantities.

When lemmings eat everything around, it happens when the number increases in tens and hundreds of times, the plants begin to synthesize the blockers substances continuously. As a result, the lemmings are unable to digest eaten grass.

In response, the body of the lemming begins to produce more and more gastric juice and as a result is depleted much faster than from ordinary hunger. And the more lemming eats, the hungry becomes. The result of a similar failure is, according to a number of scientists, mass migrations.

Man is the only mammal on earth, possessing at the same time nuclear weapon and thumb to click on the red button. We are located on top of the food chain. Do not argue with this? Some animals can think - and think otherwise than we. Spending Big Finger has monkeys.

The stunning ability of self-organization and self-sacrifice has ants, bees and rats. Circular gorillas only hippo. When a three-tonge hippo comes on a watering, crocodiles imperceptibly disappear. Fortunately, the gorilla is most good, which cannot be said about hippos.

What if they really unite against us? ..

Higher primates

The main advantage over man: incredible power and speed of movement

King Kong is a fictional character, in one fell swooping police helicopter. But half a million gorillas on our planet are extremely real, very strong and at the same time very smart. All higher primates (like their younger breeders in the kingdom of monkeys, such as chimpanzees) run and jump better than a person, and in the trees are better moving any representative of cat. Nobody measured the gorilla strength - attempts were, but suicide.

But some biologists who conducted research in Tanzania believe that the highest primates have already entered their stone age.

Fortunately, monkeys love to quarrel among themselves - the war of their tribes takes away so much that they will raise attention on a person.

Elephants

Northiness: approximately 500 thousand

The main advantage in front of a person: amazing memory

Since the elephant is essentially a biological tank, it is better not to unwind it. Judge for yourself: males weigh up to six tons, have a bulletproof skin, can pass through the concrete wall and accurately slam the person a trunk. The trouble also is that in the marriage season, the testosterone level in males is sharply rising in 60 (sixty) times.

Never go along the Elephant trail without much need. It is not even worse, but the fact that the elephants remember offenders at least in the third generation. Fortunately, if the elephant does not offend, he will not hurt any harm.

Crows

Number: about 1 thousand black raven in Moscow and about 200 thousand gray

The main advantage over man: coherence

One crow represents a serious threat to an adult, unless protects its nest. The trouble is that the crows are exceptionally intelligently and capable of going to the flock at the slightest danger and give a decent contrast to the offenders.

A classic example is the so-called Massachusette behavior of the Raven. In this American crowded crowded, the inhabitants decided to shoot them. Two days later, all the crows changed the flight plan so as to be on the verge of shooting shotguns, but a little further. You can imagine the annoyance of unlucky hunters. Under the cover of the night, the crows were returned to people and avenged a few of them for anxiety.

Fortunately, the crow is a very curious and playful bird. So, the manual raven, brought up by man, is tied to him as the most devoted dog. In general, the crows have nothing against a person while he does not interfere with them. They really like to hunt for the toad - not for food, but from sports interest: if you bring the toad into the liver, it bursts.

Spiders

Number: Counting

The main advantage over man: inspire horror

Spiders are almost in every home on all continents. According to biologists, spiders every year eaten more protein food than in the aggregate weigh all humanity. They are inborn eight-headed hunters, and they are insatiable.

Fortunately, different types of spiders are entrited and will not be able to unite against us. But be sure: while you read, you are watching.

Rats

Northiness: Counting is not calculating, but rats are exactly more than people

The main advantage: adaptability to any conditions

Mammals, like me with you - but we would not be surprised, learning that rats are made of high-strength metal. They eat almost everything, the poisons do not act on them (already in the third generation, rats produce full immunity). They breed at a huge speed. In the cities of rats there are no natural enemies, except for cars.

They are very smart and always act at the same time. In hungry for people, rats were attached to rob warehouses. Males fell on his back, and females - unfolded boxes with chicken eggs And gently passed eggs along the chain. The rats were delighted and quickly learned to steal even coffee beans.

Fortunately, there is not only a threat from rats, but also the benefits: there must be someone to collect union for us.

Ants

Number: according to some estimates, 100 trillion of a variety of species

The main advantage over man: congenital self-organization

Muraviev has no instinct of self-preservation. The ant does not exist in itself - only in his society. The anthill is very similar to utopian human society, the fact that he is dangerous. Each ant from birth has a profession: a worker, military, supervisor.

The best description of the ants belongs to the Brazilian traveler Jose River:

"His cry was worse than the cleric, which heated the beginning of the war:

Ants! Ants! "

Ants! This meant that people immediately followed the work, leave the dwellings, lay down the way to retreat and seek refuge where it fell. It was the invasion of bloodthirsty ant Tamboch. They empty huge spaces, coming with noise resembling a root of fire. Similar on the outstanding OS with red head and a thin body, they are horrified by their number and their voraciousness. In every nouper, in each slot, in every hollow, in foliage, in nest and hives, a thick fatal wave is selected, devouring pigeons, rats, reptiles, turning around people and animals ...

Then one thought took possession by everyone: to escape. They preferred to ants leeches and took place in a small creek, immersed in her neck.

Fortunately, ant flocks always enseerate among themselves, and if not to break their anthill, they will not pay attention to you. An exception is the red tropical ants tamboch, which are eating everything, even people, and where they pass, disappears all living things.

Hippopotama

Number: by different estimates, 125-150 thousand.

The main advantage over man: giant waist amount and as evil character

Hippo is much smaller than people. The numerical disadvantage with interest is compensated by three tons and misantropy weighing. In Africa, this is the most dangerous mammal. Crocodiles are snacking in half, and people in their right mind do not even come close to lonely hypopotam. Biologists have not yet found out why the hippos is crocodiles. There is a version that they do it simply because they can.

1. What animal is the hardest?

most birds ride chicks, just sitting on eggs. Their body is a source of necessary heat. Unlike them, Australian larger (weed) The chicken builds a huge incubator and uses heat that occurs when the organic substances is rotting. Bolshnaya chicken, approximately equal to the size of a gray partridge, puts eggs to the ground. Then she brings leaves, branches, lumps of land and grass and folds them into a bunch of eggs, and her height reaches sometimes 5 meters, and the width is 12 meters. This compost pile itself warms up from the inside when bacteria decompose biomass and turn it into fertile compost soil. True, the temperature in the incubator should not be above 33 degrees. The adjacent chicken all the time the beak checks the temperature and, if it becomes too warm, it grinds a little bit. With such a technique of surviving not only from parents, but also from the chickens themselves, certain efforts are required. Having raised, they immediately have to get out of a heap outside, to the air. Often the birds suffocate or die from overvoltage. A similar way to sit down chicks is used by Australian weed chickens of a different type of leipoa. Their compost heaps are less, but the top of the sand is covered on top, so that inside was warmer.

44. What masking among mammals is the most reliable?

Mimicry - so call the ability of representatives of one type of animals to change their appearance and become similar in color and form on other animals. So, for example, predators do not touch one type of inhabiting in Asia tupayi *, Because their meat is inedible. This is used by various types of proteins that the coloring "give out ourselves" for Tupayi.

* Tupayy - a family of semolstery of the detachment of primates. Body Length ~ 25 cm.

45. What kind of fish is best changed in color?

Adult cambals lie on one side on the seabed and wait for prey. To disguise, their top side automatically takes the color of the environment. Lower side always remains the same color.

She doesn't even need to turn his head to see what happens at her back.

52. Which of the night hunters see worse than everyone?

Bats hunt insects at night. At the same time, they do not see anything practically. Together with sharp eyes, they have a highly developed echolocation system. With its help, they discover where the victim is located, behind which they hunt, as well as obstacles to which should be avoided. Echo sounders work in ultrasound mode, i.e. perceive the sounds of such a high frequency, which people and most animals do not hear. When flying, bats send audio impulses: short high sounds. In the pause between the impulses, they catch their echo. Sound waves reflected from insects or items are recorded in a volatile mouse and create an internal picture of the surrounding space there. Thus, it can be said that the volatile mice "see" ears. Therefore, they do not need light to navigate, and they feel in the night darkness as confident as in the darkness of their caves. Bats hear sounds with a frequency of up to 210 kilohertz. And people can only hear sounds below 20 kilohertz. An even more acute rumor than bats have dolphins that perceive sounds with a frequency of 280 kilohertz. By the way, dolphins are also focused using ultrasound echoolets and therefore can "see" fish flocks even in muddy water or at a very big depth.

53. What animals have the best infrared search system?

Infrared rays are nothing but thermal rays. We also feel infrared radiation, for example, when we sit in the sun. With the help of infrared cameras, you can take a picture of thermal radiation and see it in the photo; Such devices instead of light "see" heat. The most sensitive system of perception of heat rays have pythons. They have a membrane in their head, which allows them to feel the slightest changes in ambient temperature. The most dark night, the python can not only "see" the sacrifice within a radius of up to 8 meters, but also to determine which size it is. It reacts to changes in temperature in hundredths graduation shares. And the body temperature of mammals is usually above ambient temperature. Therefore, they constantly threaten the danger to be discovered by Python.

54. What birds do you know how to fly in advance?

Of all the birds, only hummingbirds can fly back in advance and even stop in the air. In search of food, they hang like helicopters, in the air above the flower, lower their long beaks and suck floral nectar. In order to fully hang in the air, they have incredibly quickly waving the wings: up to 80 times per second.

55. Who growls louder than everyone?

Up to 5 kilometers is heard Creek Rezuna, inhabiting in the tropical forests of America. This type of monkeys under the sublard bone is the cavity, which serves only to enhance the voice. Little tunes - their size is a little more than 50 centimeters - indicate the boundaries of their possessions. (separate animal or flock). No other animal in the world has such a loud voice.

56. Which animal is the best logger?

In order to oversee the trunk of a tree with a diameter of 20 centimeters and to sang it, Bobru needs no more than 5 minutes. Bobra trees trunks are used to build their dams. They live in colonies in artificial lakes arising when the dams of the dams and streams are rejected by the premiums.

57. Which animal is the best drill?

Ship worms They are attached with their sinks to the tree and begin to "drill". Previously, the prey of these 10-centimeter clams were only dead remnants of trees, today they also attack on the wooden vehicles. Ship worms, digesting cellulose, cause significant damage to pile and ships. It is much harmless to sea two-sided mollusks, the length of which is 7 centimeters, the width is 3 centimeters. Mollusk is firmly attached to their muscular foot and pulls up the body and sink. Then the foot makes the next step. Thus, the mollusks move along the bottom of the sea at a speed of 20 centimeters for half a minute. Among the insects, the best drillers are the so-called riders. The back of the body of the four-sentime meter of the rider is similar to the adaptation, with which smokers are cleaning their tubes, so in some countries they are called "tubes cleaners". They feed on the larvae of a large embossing, living in the wood of healthy trees and hurts the forest. The riders are drilling a tree until they get to the larvae of the Rhohvost, and eat them. In order to drill a hole in a solid tree a hole in a depth of 3 centimeters, a rider is only 15 minutes away. Thanks to the removal of riders from Europe, from 1926 to 1936 it was possible to save the forests of New Zealand. The trees on the island seemed to be hopelessly amazed and doomed. For 10 years of work, the riders eliminated the danger of the destruction of forests with a big eight way.

The warm-blooded animals are called that constantly maintain the temperature of their body at one level. If the temperature rises above this constant value (for fever) or falls lower (when heocoled), Animal gets sick and can die. The cold-blooded animals are called, the body temperature of which depends on the ambient temperature. Fish and reptiles can often carry much lower and high temperaturesthan warm-blooded. For example, lizards become truly active only with heat. Of all the warm-blooded, the highest normal body temperature in pigeons and ducks (up to 43 degrees)the lowest body temperature in the Muravda (29 degrees).

59. What animals carry the lowest temperatures?

Grape snails can be safely placed even in the freezer: after thawing, they feel great. They are withstanding (short time) Even the temperature is minus 110 degrees. But they are sufficiently sensitive to the heat and die when the temperature rises above 50 degrees. Frogs can be inserted into ice with minus 10 degrees and remain safe and unharmed. Some kinds of fish are transferred to the ice of frozen lakes. True, ice temperature (and thereby the temperature of their body) Should not fall below minus 15 degrees. Among the warm-blooded recordsmen are cats. When the temperature of their body decreases to 16 degrees, they, however, lose consciousness, but as soon as it becomes warmer, come to themselves again. But absolute recordsmen Still are bacteria. Some of their types are withstanding the temperature minus 250 degrees. Heating to plus 90 degrees also does not harm them. But most bacteria dies at temperatures above 100 degrees. Therefore, to destroy many bacteria in the water, you just need to boil the water.

60. Why does Lynx hear so well?

Of all the land animals, the most acute rumor in the lynx. Tassels on her ears are thin hair beams - catch the quietest sounds and transport them into ears. Lynx can distinguish between the various noise from the distance to a kilometer.

61. What mammals lay eggs?

Concurrents and echids are the only unbelieving mammals. They lay eggs.

These animals are found only in Australia. The fact of the existence of such animals received scientific confirmation of only 100 years ago. Prior to that, reports of egg-owned mammals were considered fairy tales. The length of the fleet of the clock is an approximately halfter, its beak resembles the beak of the duck. He raises eggs like a bird. From the spur on the feet, WKONOS highlights a poison that can kill a small animal.

62. Does the most animals live on?

The sloth bears his name with the full basis. It is a strange creation of a half-meter and weighing 10 kilograms, the whole life is lazily hanging in the crown of trees in American rainforest. Fruits literally fall into his mouth. The sloth moves very slowly, for each step he takes a few minutes. In his wool, the whole colonies of living beings are inhabited, starting with green algae. The caterpillars of one type of butterflies eat algae. Finally, there are still small ants in the fur of the sloth, which feed on the caterpillars of butterflies.

63. What mammals are the most rare?

A number of mammals occurs so rarely that only one single detected instance is known about their existence. For example, in 1938, a fruit bat was caught with small teeth; Since then, this tropical bat no one else has come across anyone. It is assumed that there are only a few copies and a Tasmansky soup wolf. The constellation was believed that it was a long time ago, however, in 1982, a reserve employee managed to track down and identify one of these ancient animals. Other mammals such as the Black Fossa or Red Wolf, managed to protect from full extinction only due to breeding in zoos. They were already released again to the will, and scientists hope that they will survive in natural habitat conditions. Probably the most rare of all marine mammals is one type of sharp whale. No one has seen any live instance. The fact that this kind of whales generally exists, it is known only on the found bones. More than 1000 species of birds have such not a large number of Representatives that the view is under threat of extinction. Maybe the greatest danger threatens with a gray coastal sparrow, who had previously dwell in Florida. The last famous copy of this species died in 1987. True, parts of its corpse are preserved under deep frozen conditions. Scientists hope for further successes of genetic engineering. Perhaps over time, it will be possible to reproduce this type of genes preserved in cells. Then it would be possible to give a gray coastal sparrow a second life.

64. What animals use various implements and fixtures to mining food?

Many animals use various guns to get to food. But chimpanzees can be the same to make such implements or devices. Experiments with chimpanzees living in captivity showed: If you hang bananas to the ceiling so that the animals cannot reach them, and in the room put boxes, then after some meditation, the chimpanzees will be built from the boxes something like the stairs and take it to bananas . On the wave of chimpanzees, sometimes fit branches for the hunting of termites. They process wooden sticks until they purchase the desired shape and thickness so that they can be inserted into the solid. They chimpanzee is pulled out of insects from the gunner. A red-headed finch, who wishes to enjoy insects, finds a sharp spike, takes him in the beak and picks them in the tree bark. But sometimes to get to the feed, you have to first split the shell or shell. To get the oyster, the marine width of the stone splits the sink. Sometimes you have to split the houses of snails and eggs. Birds are easier than land animals. They simply rise with their prey high in the air and throw it on the ground. In this way, the vulture gets to well-protected the contents of tubular bones. They dump the bones with big height On stones, where they are broken. There are many messages that exactly the stamps are broken by the turtle shells.

Macakka IMO is still considered the only animal, followed by observing at a time when it made the invention. Amazing discovery Made Japanese zoologists at the same scientific station. It turns out, not only people, but also animals can solve the problem by thinking (and not just by trial and error). Smart monkey Begg over the question, as she quickly get rid of the tasteless sand on potatoes, without spending time on scraping. Suddenly she ran to the water and put potatoes there: the sand was easily flushed. The smartie imo liked this way that she used it and clean the rice, which was lying on the ground for a long time and stirred with sand. The sand sank in water much faster than rice, and pure rice grains easily managed to catch. No one assumed that animals are capable of such deliberate acts. Interestingly, soon all young monkeys of the colony learned and adopted this technique. But the old monkeys did not want to retire. They continued to eat food mixed with sand. Dolphins, a lot of thinking, inventing various methods Protection against fishermen, also you will not refuse intelligence. Previously, hundreds of thousands of dolphins died, falling into fishing nets, thrown on the tuna. The fact is that some of their species love to be nearby from the flock of Tuna and attract the fishermen. But this is what the whales researchers are observed: Recently, the dolphins seem to understand that near fishing vessels it is better to stay quietly and imperceptibly. If all the same, the ships were too close, the dolphins are trying not to swim to them on the other side with which they lower the network. If they nevertheless fall into the area of \u200b\u200bthe fishing area and are surrounded by grids, they no longer shook them in a panic, as before. They are waiting for ships, lined up in a circle, will go away a little back. At this point, the dolphins swim over the network lying deeper, or jump out and turn out to be free.

68. Which languages \u200b\u200bexisting in animals are the strangest?

Along with the languages \u200b\u200bof gestures and the language, the sounds published, in some animals, primarily in insects, the real language of smells are developed. For example, Ecoofilla ants produce 10 different odors that are combined with certain body positions. Thus, ants can be transferred to 50 various messages. A very expressive language of smells uses spotted skunk. He sprinkles the enemies of smelly liquid, which means: "Logging!" This smell is so sharp and disgusting that with good wind it can be felt in a few kilometers.

Since ancient times, people living on the seashore know many such stories. A number of other herd animals also help their relatives. Even animals with such a bad reputation as coyota are divided with patients and weak coins. Lvov has a sense of partnership show only females. Vampire bats are even sharing with patients with blood vampires. South American vampires feed on the blood of other mammals. If the patient of a bat cannot go hunting, then "comrades" bring her blood in the mouth and feed it. Whales and dolphins, elephants and manoid monkeys Even seems to have sadness, if, despite all their efforts, one of the relatives dies. About whales tell that they lose vital energy and cheerfulness when one of them dies (for example, from harpoon kitolov). Jane Goodwell, who studies chimpanzees, told such a story. One young monkey could not survive the death of his mother. She all came to the place where the mother died. And died in the same place in a few weeks - obviously, from grief. It seems, elephants also understand what disease and death is. They do not throw a sick elephant, on the contrary, in every way he helps him. If he falls, the rest are trying to put it on their feet. If he does not give signs of life for a long time, then the members of the herd carry something like a guard guard near his body. Before you go further after a few days, they are thrown to the corpse of the deceased fellow earth and branches.

73. What animal sleeps longer?

Predators from the feline family sleep or at least dorm most day. They can afford it, because they have no enemies "Iim don't have to be all the time alek. Gorilla is also so confident in his abilities that it can sleep daily for 13 o'clock. Even longer, 18 hours a day, heerie, curled In the prickly ball, which is not terrible.

Perhaps just for a long time, and maybe the sludge sleeps even longer. This is not known: this is an animal living in Mexican tropics, moves so slowly that it is impossible to install, he sleeps in this minute or not.
