Refreshing or reptiles as turtles, snakes, crocodiles of aging rates are much lower than most mammals.
How many years live turtles
Turtles although they belong to one of the four merchants of reptiles (turtle, crocodiles, scaly, beakhead), but show other signs of aging unparalleled with many mammals. Unlike some animals and many species of fish that are constantly growing throughout life, these animals are usually growing slower in old age. As amphibians, most reptiles have replaceable teeth.
Several species of these reptiles seem to have insignificant aging and life expectancy relative to the long.
Swamp survive and have a reproductive exit for 75 years. Similar results were recorded for a box turtle. Marion Turtle, as claimed, has a life expectancy for more than 150 years.
How many turtle live is uncertain, but obviously a long service life, since some in captivity live up to 70 years. An increase in mortality was found in wild species, but the external natural factors here, most likely played a role. A distinctive feature of these animals is a shell that protects against enemies. Maybe therefore this species lives long enough, including in nature.
Two examples of long-lived reptiles that do not show any signs of aging. A): Box, which can live up to 138 years. C): Galapagos, which lives up to 177 years.
Since this special animals exists a section of the zoology of herpetology, which studies these reptiles.
Galapagos turtles long-lived with a possible record of the longevity of 177 years.
Refrigerated Class Complete Chance
If you answer how many snakes live, it is known that they can also avoid long aging. Many species actually laid more eggs when their age increases. Myths How many snakes live, as long-livers, no more than myths.
Snakes live in captivity up to 10 years, larger as python, manage to live to 30 years.
How long does a crocodile live
Some species have reproductive aging like reptile, although further research is needed. For example, it was reported that crocodiles reduce reproduction at the end of life.
Although evidence is limited, but how many crocodile lives it seems that they show a less intense aging phenotype than mammals of many species and is not indicative of the characteristic maximum life.
It is known that in the captivity of the crocodile up to 100 years, and in the wild, they rarely live up to 50 years.
The relative longevity is associated with the genotype in accordance with which their growth does not stop and therefore they can grow to large sizes.
Thus, many species of reptiles do not have a clearly defined sense of life associated with their physical age.
Of course, the life of reptiles is full of many myths. If a Information is enough, then we know about these animals.
The crocodile recognized the largest land predator of nature. The size of animal is colossal. To maintain vital activity requires a lot of strength and food.
These animals appeared on Earth millions of years ago. And today their appearance does not differ from the predecessors. The average life expectancy is about 100 years old, it all depends on the sector of habitat. In the wild, life lasts - 80-100 years old, in captivity - 40-50 years old with proper content. In the article, we will look at the lifestyle of one type of crocodiles - Nile.
Nile Representative, like everyone else, short-legged. The limbs are from the side of the body. Animal scaly, powerful. Eyes (ears and nostrils) are on top on the head. This makes it possible to almost completely under water. Animal color palette, gray or light brown with stripes, makes it possible to be inconspicuous. With age, almost not visible.
The skin of the Nile crocodile is considered the most expensive and high-quality.
Often animals move on the stomach, but can walk with the raised torso. The individuals of small sizes can run gallop, for short distances at a speed of 12-14 km / h. The speed in the water is 30 km / h.
Nile crocodile - a predatory animal, to meet that can be in African countries. Hunting predominantly on animals, but is a danger to a person. The population of this particular type is large enough.
By virtue of its magnitude, crocodiles are hunting for animals greater than its size, avoiding elephants and hippos.
Parameters of an adult individual:
- Length - 5 m (met 6 m).
- Mass - 225-550 kg.
The crocodile heart consists of 4 cameras - it gives the long period to be under water (up to 2 hours). Slowing metabolism and low body temperature allow you not to eat daily, but at one time an animal can absorb food half of its weight.
The crocodile diet is completely meat. Crocodiles, which appeared on the light, eat small water insects and insects. After a couple of weeks, food becomes more diverse and large.
Adult individuals use large food, fish, animals and birds, which drink water on the shore of water. These may be the lions, hyenas, leopards, monkeys, zebras, etc.
The Niel Crocodile is a big danger for a person. According to numerous data, he takes about a thousand lives.
During the hunt, predators behave carefully. We wait for the victim away from the shore hiding under the water. Further, they are sharply attacked by teeth death bites, or drown. Can eat Padalu, just not rotten.
Reproduction
The reproduction period in the Niel crocodile depends on the area of \u200b\u200bresidence, in the northern part is the time of drought, in South - rainy time. The males are fighting for the attention of females. With the "lady" remains the one that will win the fight. At the same time, they can snatch, roar, splashing.
Upon completion of the mating, the female is removed in search of a secluded place for egg laying. Most often it is sand. 20-100 eggs may be postponed for the masonry. After 90 days, a new offspring will appear. All this period, both parents defend the masonry.
When kids appear on the light, the mother helps them get to the water. They live in shallow water up to 10 weeks. The younger generation differs in search of shelters and food. The life expectancy of the crocodile in such conditions is about 45-50 years. There are cases and up to 85 years.
Nile Crocodile shall be divided into several types:
- Ethiopian.
- Malagasy.
- Central African.
- West African.
- East African.
- South African.
- Kenyan.
As you know, the crocodiles live much less in captivity. The reasons are different:
- With antiquity, people have become massively exterminating these animals so that they do not hunt for a cattle.
- At a certain period, the world enveloped a wave of fashion on crocodile leather products.
The number of killed crocodiles for the sake of skin is colossal. Statistics:
- Killed - about 1 million.
- Sold Skur - 190 thousand.
In 1944, a law was adopted prohibiting the hunt for these animals. Otherwise, the American Alligator will extortion at all.
Today, hunting does not stop, poor nations risk life to catch the crocodile and sell it to the skin. Young mothers die, eggs remain without protection. Therefore, the survival rate of the livestock is reduced.
The lifespan of the crocodile and the mass change in life conditions. The forests are cut down, the reservoirs dry up, bridges and dams, shops and residential villages are erected. This fact also reduces the number of different animals that feed on the crocodile.
For this reason, predators can eat extinct species of fish and animals. For some individuals, such a coincidence plays a positive role. The places that the female prepares for the masonry of the eggs are filled with water, and there are various fish there, the bird's water arrive.
Crocodile American (pointed). Have a large size, up to 6 meters. Color gamut brown or olive gray. Weigh about 400-500 kilograms. Live on average up to 45 years. Eggs, pending with female, can steal raccoons, wild cats, birds. People practically do not attack.
Crocodile African narrow. The size of the average is about 3-4 meters, the weight is 230 kilograms. The color scheme is diverse, olive-gray, almost black, brown. There are dark spots on the tail. Lives about 50 years and more. Listed in the Red Book. The main enemy is a man whose goal of the skin and meat.
Orinoksky crocodile. One of the largest, length of up to 7 meters, females are not more than 3.5 meters. Weight - 200 kilograms, there were an individuals of 350 kilograms. The color gamut is redhead with brown, the body is covered with dark spots. There are an average of 50-60 years, there is no accurate data. On babies hunt birds, snakes, foxes and man. The skin is of great value due to large size.
Crocodile Australian narrowed. Lives in fresh waters, fine enough. The size is no more than 3 meters, the weight is 90 kilograms males, 45 kilograms of females. Color gamut brown with dark stripes. Lives no more than 50 years. The main predators are wild pigs, hunt eggs. Food is mostly fish. Listed in the Red Book.
Crocodile Phillipsky. The size of the individual is fine enough, rarely reaching 3 meters. According to some given, it lives near a century. The main enemy is a man. It is powered by water inhabitants, reptiles and invertebrates. Located on the verge of extinction, listed in the Red Book. Today in nature no more than 200 individuals.
In the section on the question how many crocodile live? Posted by the author Mansion The best answer is The life expectancy of crocodiles and alligators in the natural habitat is not so great:
cayman - about 4 years old.
At the moment, the older crocodile is the MissiPian Alligator from Australia, which died in 66 years. In the medium, under good conditions, the crocodiles are capable of living up to 40-50 years.
Answer from Your Mightiness[guru]
60-80 years of about. In the wild to 100 it happens.
Answer from Beauty[guru]
80-100
Answer from Wake up[guru]
Promotional crocodile: 70 years
Nile Crocodile: 70 - 100 years
Mississipa Alligator: 30 - 50 years
Answer from European[newcomer]
This animal is recognized as the largest land predator from all existing ones. Crocodile or alligator can achieve truly huge sizes for its life. Accordingly, it takes enough food and time for this. Well, if everything is fine with the first, how is the case with time? How many crocodile live in wildlife and at home?
One thing to say unequivocally: the life expectancy of crocodiles and alligators in the natural habitat is not so great:
Nile crocodile - on average 8 years;
Mississipa Alligator - about 5 years;
Gavial is a major reptile squad of crocodiles, lives on average for 6 years;
Cayman - about 4 years old.
At the moment, the older crocodile is the MissiPian Alligator from Australia, which died in 66 years. In the medium, under good conditions, the crocodiles are capable of living up to 40-50 years.
The largest and most dangerous terrestrial predator - crocodile - does not have the nature of the enemies more dangerous than a person. Actual life expectancy crocodile In the wilderness, it is very different from the maximum possible.
The value of crocodile leather is still large in the black market, and in addition, the reduction of habitats forces crocodiles to settle close to people, which invariably increases the risk of danger for the latter. Naturally, it also leads to the extermination of crocodiles.
The most difficult and dangerous period of the life of crocodiles is childhood. At the age of the year, 90% of young crocodiles die. But if this reptile passes a one-year-old frontier, then at the age of about 1.5 years, it reaches 1 - 1.5 meters and will acquire a very serious argument in its defense: sharp teeth and powerful jaws.
According to different data, the average life expectancy of crocodiles is 20-40 years. But in zoos recorded cases of long-life among these reptiles: in the Australian Zoo, the Nile Alligator lived to 66 years.
In one of the zoos of the American continent, a crocodile lives in the age of 100 years.
And the Moscow Alligator lives in the Moscow zoo, who in 1946 moved from the Berlin Zoo as a trophy already in the elderly. That is, now his age is far from 70 years.
Life expectancy crocodiles Over 50 years in the natural medium is considered to be the maximum possible in ideal habitat.
Crocodile
Crocodiles are the largest reptiles living now on Earth. Sometimes they are called "shell lizards", and this accurately reflects their main sign - strong skin. Large horny shields and bone plates cover the whole body, forming a shell.
"Crocodile" - the Word of Greek origin meaning "stone worm". Crocodiles are the largest forms of modern reptiles and are the last descendants of the branch, which belonged to dinosaurs. They appeared during the end of the triad and the beginning of the Jurassic period 150 million years ago and there were from one land ancestor. The same ancestor will start and birds . To which crocodiles according to some features of the inner structure (including in relation to the perfection of the brain) are much closer than other reptiles. The crocodiles have acquired a number of features necessary for existence in water.
They have short and severe paws, a large triangular head, a short neck, an elongated muzzle, strong jaws with sharp teeth and very highly planted eyes. The bottomable body shape makes it easier to swim, flat and powerful tail performs the function of the motor body. Crash usually greenish-brown, leather covered with very durable horny plates. On the back, these plates form rows of longitudinal ridges. Crocodiles, unlike many other reptiles, do not lose, as their skin grows after the growth of the body. Crocodiles can change the color of their skin. It depends on the ambient temperature. What it is higher, the topics of the skin more green shade.
Like many major reptiles, crocodiles live for a very long time. The maximum duration of their life is 100 years.
Crocodiles are closely related to alligators and caymans. Like those crocodiles, too, have been subjected to ruthless extermination. They saw a danger to a person, and moreover, expensive luxury objects are made of their skin. Unfortunately, large species were destroyed primarily, and Nile crocodiles now almost won't meet in the wild. In former times, this species was distributed throughout Africa, including the island adjacent to the continent, and throughout the Asia Minor; Now he has practically disappeared from many regions.
During the breeding period, the crocodile female comes to the sandy coast and the pit of the pit, the depth of which depends on where it is located: in the shade - smaller, in the sun - deeper. In this pit, she lays up to 50-60 eggs at night and throws them with sand or leaves. The development of embryos in the eggs (incubation) lasts about 90 days, during which the female, without feeding, remains constantly at the nest and protects the masonry. On the floor of the crocodile affects the incubation temperature of the eggs: above 32 ° C - the male hatching. From 28 to 30 ° C - female. By the time of hatching, crocodiles serve grunting sounds from egg. This serves as a signal for a female, which digs eggs from the sand. Racing eggs in the toothy grazing, crocodile frees the recluses from the shell. Materials lasts long - just a couple of days, and then the younger generation is provided by itself. Therefore, mortality among small crocodiles is extremely high. Young is birds, fish, varana and other predators.
The rampant young is small - just up to 28 cm in length. The gift collects up to 20 crocodiles in the mouth at a time and tolerates them into the chosen one in advance, the newborns spend 6-8 weeks, remaining under the protection of mother and father, And then settle around the surroundings, looking for water bodies that are not engaged in adult crocodiles. Adults are filled with insects first, increasing in size, catch fish and frogs, and finally, reaching almost 2.5 m in length in 10 years, begin to hunt larger animals.
The crocodile detachment includes more than 20 species of crocodiles actually, kaymans and alligators living in various ponds of tropical and subtropical zones. A large-scale crocodile (up to 7, 5 m long and more than 1 tons). It is widespread from India to Oceania. And it can swim in seawater. Missicipa alligator 2-6 m long. It will be in the swamps, rivers, lakes in the south-east of the United States. Fashionable for humans. Cayman is the largest and most dangerous of all Caymans (up to 4.5 m). It is found in the basins of the Amazon rivers and the Orinoco to Guiana. Poor Cayman-leads in the rivers from Mexico to Paraguay. True crocodile-rare Central American view. Niller crocodile length is 5-6 m, it is found in Africa. Version predator, attacker even on very Large mammals.gavial-length up to 6.5 m. Lodels in the north of Industan, feeds on fish, for people is not dangerous. Bolknye crocodile (Maper) reaches 4 m. Estimates in India, Pakistan, Nepal. Cytai Alligator rarely exceeds 1 , 5 m. Lodels in rivers, lakes and swamps In the lower flow of the Yangtze River.
Nile Crocodile Crocodylus Niloticus
Refer to the class of reptiles, crocodiles family. Length is length from 2 to 6 m, weight up to 1000 kg, habitat - African rivers, lakes and swamps. Poultry, fish, hoofed animals. Crocodiles have enough sacrifice and drag under the water, where first They drown it, and then devour. They hunt mostly on fish and small vertebrates, but adult crocodiles are easily coping with rather large animals. The fall is formed by strong and very long jaws, which are equipped with sharp teeth. Fits, crocodile skin is covered with bone plates on Back and scales on the belly, which do not allow moisture to evaporate through the skin. Therefore, in order to highlight the surplus of salt, these reptiles are forced to shed abundant tears from the eyes. The "Crocodile Tears" says that it is this imaginary crying crocodile jaws that are responsible for closing the jaws, very strong, and those that open them are rather weak. Crocodiles can hungry for a long time; it is believed that they are able to hold out without food to six months, or even more.
Crocodiles have almost no enemies, except for large terrestrial predators, especially dangerous in collisions on land. Sometimes the outcome of these battles is in favor of crocodiles, and sometimes the top leaving lions or tigers.
Once upon a time, the Niel Crocodile also inhabited the coast of the reservoirs of the Middle East. Okhot on Nile crocodiles, mainly due to the value of their skin, led to a reduction in their number, and in many areas of Africa they completely disappeared. The result of the tropical reservoirs has changed, so As crocodiles are the most important signs. They devour the sick animals - and living in the water, and coming to it - their remains and weed fish. There are certain measures to protect these terrible predators, they are even bred on special crocodile farms. Animals are gradually restored.
Nile crocodile loves to lie on the sandy suspense
The only appearance of the genus Gavialov - Ganga Gavial lives in the rivers of India. It reaches 6.6 m. They even feed on fish and small animals in adulthood, which they are enough with an enviable dexterity of skillful swimmers. This crocodile is more rated. His plane tail Comb is coming - Gavial enjoys them as an oars, for maneuvering in water. In contrast to the alligator, he hunts on the fish. When his face stretched sharply: instead of a wide "Cappan", he had a subtle graceful "tweezers" for fishing. It became extreme Rard due to the destruction and pollution of habitats, predatory fishery and death in fishing networks. The special government program of India to preserve this species was launched in 1975 and allowed to increase the number of gavials.
One of the largest. Copies up to 7 m long are known. It inhabits the mouths of rivers and estuaria, sea lagoons, mangroves overgrown with the coasts of the Indian and Pacific Oceans of Southeast Asia, Australia and the adjoining islands and archipelagos. It is not afraid of salt water and swims in the sea where it was often discovered In dozens and even hundred kilometers from the nearest shore. Thanks to this, they spread to distant from the mainland of the island.
The usual mining of this predator - fish, crustaceans, snakes and turtles. But since this crocodile attacks both large animals, then it is often dangerous for a person. The creamy crocodile is putting eggs into the nest, built of fallen leaves. Genetically is an impressive structure to 7 m in diameter and up to 7 m in height. Drinking leaves are maintained in the nest a constant temperature of about 32 ° C. It protects the masonry, and then some time protects small crocodiles.
Most are found in freshwater swamps and in inland water bodies.
Alligators close relatives of crocodiles and kaymans. On land, these armored lizards move very slowly.
Their elements - water, there they hunt. And then only convex eyes and nostrils are visible above the surface. If production is suitable enough, clumsy alligators are transformed. They grab fish or turtle and quickly swallow. So it is better not to approach alligators. While young grows up in the eggs, the female looks after the nest.
The Missisypian Alligator has an interesting feature - he digs and supports ponds that become a permanent stay of life for many types of freshwater plants and animals, especially in the period of drought. The aligator is building on the shore of the pond on its territory a nest of algae and torn grass, where posts from 20 up to 60 eggs. Just like other crocodiles, it protects the masonry, and then helps small alligators get out of eggs and relates them to the grazing in advance selected and equipped with a reservoir, where he continues to protect a few more months.
They belong to the same detachment as crocodiles. Their differences in the crocodile sizes are slightly larger than Cayman. The whole is covered with large and dense shields, with powerful jaws and a strong long tail. Caimans are characterized by a wide and short muzzle. Like their close relatives of alligators, they are found only in America. Among the most famous types of Caymans can be called Zhakar, or Paraguayan, Caiman with a wide mouth (Melanosuchus Niger), the largest predator in the Amazon basin. The males are divided by the territory, observing all the rules of hierarchy, and females They can live in one nest to make it easier to defend themselves from the enemies. It is longer for Caymans and sharper than from other family members, alligators.
Caymans live in lakes, swamps, ponds, rivers and - rarely - in lagoon with bitter-salt water. They prefer standing water by flowing, patiently transfer low moisture levels and love the place covered with the sun. Standing the islands, or "mats", which are sometimes Can reach 900 m 2. - Beautiful refuge for young individuals.
When Caymans go under water, the special moving areas of the skin closes the ears, the nostrils and the trachea, so that the water does not get into the lightweight Water, but often with the onset of twilight, they come out of the water and hunt to land freely.
There are several types of Caymans: two types of spectacles, one species of black and two glazing. If the points of the Caimans reach a length of 2.5-2.7 m, and the smooth 1.25-1.45 m smoothly, then the black length is up to 4.7 m. This reptile is very large and can grab even a cow. This is one of the reasons for the extermination of Cayman residents of Central and South America.
Another reason for the extermination of Caymans is their skin. Crocodile leather products are in great demand, and many predatory lizards break up with life for boots or handbags. As a result, the number of kaymans is steadily reduced. Some species are almost exterminated, despite recently adopted laws on their protection.
In Brazil, Caymans are bred on special farms
Color Depending on the type of Cayman can be green, brown or black color. The black kaymans are a big commercial value, and it is for this reason that they ruthlessly hunted them until they became an endungent species.
The need for food in these animals depends on habitat and their size; Usually, the more Caiman, the larger the prey, consisting mainly of fish, birds and mammals. Caymans, like alligators, fall shorter and wider than in crocodiles. He has a round shape and protrude due to the bone ridge.
After mating female Caymans build "Incubators" - nesting hills from the ground and rest of the plant. Female crocodiles dig holes on the beach. September to October, while the tropics do not rise rains, the female puts eggs. In the masonry from 15 to 80 eggs. After about 70 days, the kids split the shell and run to water. Mother always stays nearby - guarding the offspring. In Suriname, Cayman is active only at night - they hunt insects, and the mother constantly looks at the offspring.
How to distinguish crocodiles from alligators and kaymans? In crocodiles, the 4th lower tooth sticks out with a closed grazing, and everyone else is blocked by the upper jaw and immeasured.
The strength and power of the crocodile are not only scared, but also strangely attract attention and admire. In the ancient Egypt, the crocodiles were objects of worship-people worshiped God bite with a crocodile head. In his temples contained many of these animals, which were fed and drove slaves. Reptiles were decorated with gold necklaces and took care of them in every way. After the death of the sacred crocodiles, they were embarrassed, and their mums were buried in the tombs of the temples. Crocodiles were forbidden to kill, and the violation of this ban caught death.
A little later, the crocodiles were interested in the ancient Romans. The zoo in which the crocodile was also considered the highest chic among the Roman Patriches. Crocodiles were often settled on the rights of indoor pets in homes of noble people and fed fish. Crocodiles and negligent slaves came to lunch, with something pricked owner.
Now crocodiles are blissful in zoos under lamps, in ideal conditions for them, and visitors enjoy the type of archaic monster through durable glass. But in America, in the places of natural habitat of crocodiles, sometimes the wars between the man and the crocodile still flare out: alligators settle near settlements, where farmers are delivered.
