In the world of wildlife a huge number of amazing creatures. They are divided into many groups, among which, fish, insects, predators, amphibians, etc. All these groups are unique, however, the latter does not have a lot of fans. Yes, the appearance of slippery small creatures, indeed, may seem repulsive, however, they also deserve attention.
Popular types of frogs: Kvaak, lake, Dominican, Slogaty, Ostroordy, Siberian, Pond, etc. Talking about how many types of frogs exists on earth, we note that today is more than 500.
They live on different continents, differ in behavior, eating preferences and external parameters. But, each of the five-hundredth unites one thing - the absence of near-dry glands. By the way, it is these frogs differ from their closest relatives ,.
Dominican Kvaqsha
If for the first time to observe the movement of such a creature, for sure, the opinion will arise about its clumsiness. And it is absolutely justified. This frog really moves quite problematic. It's all about its specific physique, or rather a disproportionately big head. In its edges there are large black eyes closed with a large fold of frontal leather.
The mouth of the Dominican Quake is also wide enough. I wonder what this type of amphibian frogcreated in a very short time to completely change the color of the body. The main factor contributing to this is a sharp change of weather. However, Dominican Quake is capable of changing the color even when changing the mood. Such talent in the world of animals has not everyone.
Dominican Kvaqsha - predator. It feeds almost to everyone that comes across her way. If the amphibian is hungry, then it can eat even their own children. During such a bloodthirsty classes, it publishes a fooling sound, resembling "Vary-Kry".
Pond frog
This cute inhabitant of water bodies is found not only in, but also beyond. Based on the name, it is not difficult to determine that the habitat of this creature is reservoirs. A feature of the pond frog is unpretentious in choosing a lake, a pond or river.
It will settle in any reservoir, where there are food and pita, where you can sit looking out for the midges. Still of the physique - 10 cm. Greenish-yellow skin of the pond frog is covered with brown stains. In the center of its back passes a narrow strip. An unusual species feature is good development Drumpocking.
Edible frog
Zoologists argue that the ancestor of the edible frog was a hybrid of lake and pond. Such view of frogs in the photo It looks especially beautiful. The individual has a pleasant salad and green shade of the body. Its front part is diluted by beige paints. From head to the rear paws pass black stripes of different widths.
Why did the frog nicknamed "edible"? The paws of this amphibian is one of the favorite delicacies of the French. Are found edible frogs, mainly in European water bodies. She is demanding towards the village of Selion. If the amphibian will establish that there is no current in the reservoir, it is unlikely to settle there.
Australian Quake
Such view of green frogsrightly named zoologists one of the most beautiful . According to dimensions, Australian Quake is not inferior to Dominican, however, by his appearance, it radiates friendliness, unlike the second.
Body color - brightly salad. Breast of Australian Quakes is a little lighter than the back. By the way, along the entire surface of her small body there are barely noticeable black dots. The color of the eye is yellow-gold.
However, it changes periodically, however, as the color of the whole body of live life. Kwaksha becomes turquoise or light blue. But this particular is known by his voice voice. Many people do not like the sounds published by the Australian Quakes, and this is not surprising, because they are very much reminded by the barking of an irritated dog.
Charming leaselaza
This type of poisonous frogs very handsome. The body has a black and golden shade. On her back clearly visible orange strips. The charming leisure cup is slightly suited, the eyes are large, black.

It is worth noting that this beautiful frog - One of the less poisonous. It rarely attacks others, preferring to conduct a single and friendly lifestyle. However, it is impossible to call a cautious one frog. It never hides to hide, as it knows that, due to the presence of a toxic substance, a few will conflict with it.
Transcaucasian frog
Mediterranean appearance (up to 8 cm). The specifics of the Transcaucasian frog is its pink abdomen. Not so long ago, this species was widespread in Krasnodar Territory Russia, however, pollution of water bodies led to a reduction in its number. Today, the Transcaucasian frog is one of the extinct species listed in the Red Book. This rare view frogsprefers to eat not only insects, but also crustaceans.
Blue tree
In fact, Blue Trees, in itself, bright and contrast. On all its slippery skin there are black circles. By the way, the blue tree is a frog poisonous. Toxic substance This species can even kill a person, however, this happens infrequently. Much more often, Blue Trees kills with its poison of forest and steppe predators.
Some people are breeding tree in household terrariums, without fear of their poison, which in a safe environment is less frequent produced by its skin.
Large frog
This amphibian does not apply to "small frogs". The body size of the lake frog can reach 16 cm, but for this, the individual should be well and regularly feed. On lakes there are gray-brown or green-yellow individuals. The lake frog is an excellent mask. She can hide in foliage or Ile so that it would not be able to find it even to people with very good eyesight. The head of this species is very wide, massive.
In addition to Russian reservoirs, this species is distributed in some European countries and even. It is attracted by deep water. The main food of the lake frog is water beetles, but it can be touched by other insects.
Interesting fact! Large frog - valuable for medicine and biology amphibian. It is caught in the purpose of experiments, testing medicinal preparations, study of the internal and so on.

To study a purple frog was able relatively recently, in 2003. Love for Earth has reflected on the food features of the species, it does not go to the surface to catch the midge, as it prefers to eat underground termites.
Frog-Aibolit
By the way, they feed such amazing creatures Only in water. But treatment is not the only one useful property Frog-Aibolita. Its skin isolations have a cleansing effect on aquarium water. Despite its small dimensions, the aibolit frog brings great benefits.
Exterior a distinctive feature of this type are powerful hind legs, they are quite fleshy. With their help, the amphibian easily breaks its food. Tip! If you decide to keep a frog-aibolit in aquarium, like a pet, it will have to sleep with something so that the amphibian does not jump.
Ostroordy frog
The peculiarity of this slippery creature is a pointed face. This is a small part, up to 6-7 cm long. There are stains and stripes throughout its skin. IN wildlife There are not only brown, but also olive ombid, less often - black. Some natural factors affect the color of the body of amphibian, for example, the level of humidity.
In nutrient preferences, no specific this species did not stand out. An animal is often racking with flies, a heated, etc., it often violates its masking at the time of hunting, becoming easy prey for forest predators. While the weather is favorable (frosts are missing), the frog spends time on the shallow water, but it is worth come the cold, and it will look for refuge in nonorah, stones or foliage.
Single poisonous frog
This species has a very bright color. Do not notice a mon-pine frog is very difficult. Guess what it stands out? Of course, a bright orange or red back. It is referred to the number of poisonous amphibians. However, the poison of such a frog is not enough to poison a person or a large predator. Nevertheless, contact with such a creature can cause serious health problems.
The toxicity of the frog is transmitted from poisonous ants, which it uses. Then the poison will be released by the skin glands of the amphibian, but it controls this process and does not consume the margin of the poison without necessity. Usually, the reason for the release of skin toxins for a red-eyed frog is an attack of a predator.
Siberian frog

Watching the frogs you can learn many curious and stunning things. In the episodes of life, salvation from enemies and other non-standard situations, amphibian frogs sometimes behave extremely unusual. Periodically, the frog resets the skin that is not necessary for life by the body, and eating it continues to live until the new one does not grow.
Homemade frogs often contain in aquariums, trying to be closer to nature. Many types of frogs bred in scientific laboratories For experiments and biological research.
Food
Insectivorous frogs They are predators, with pleasure by drinking, and small invertebrates. Particularly large do not discern and more impressive prey, some species of animal frogs are even mercilessly devouring their own relatives.
For hunting for their victims, the frogs use a sticky and long language, which are deftly catching right on the fly of the midges, and other animals. There are among the types of frogs are also omnivorous animals, with pleasure eating fruit.

Frogs are eaten by making them extremely original disheswhich are delicacies and are used for exquisite tables.
Reproduction and life expectancy
Frogs breed, laying out the caviar in the water, and its number is truly huge and amazing the imagination, sometimes reaching 20 thousand eggs at a time. Herbal and pond frogs are postponing to hundreds of icons that are big lumps. Sometimes females are engaged in these groups.
Golobastics hatching from the cheekbones. These creatures are larvae of frogs, breathe habia, can exist and move only in aquatic environment And have tail. The transformation of the eggs in the headstands takes from 7 to 10 days.
Over time, the tadpoles begin to change much, pass the stage of metamorphosis, which lasts about 4 months. First they grow rear limbs, then the front, then the tail-steering wheel disappears, and the tadpoles turn into adult individuals with distinctive features His type of frogs ready to live on Earth. In three years, frogs are getting full.
In the photo Ikrinka Frog
Measure the life expectancy of frogs is quite difficult. But according to the following scientific research, With the use of growth in the phalange of the fingers for the seasons, data were obtained that allowed us to consider that adult individuals are capable of living up to 10 years, and taking into account the stage of headstuffs up to 14 years.
Frogs (Rana) are a common and widespread name that combines a whole group of animals, which relate to the detachment of elderly amphibians. IN wide understanding this term Apply to any representatives relating to the detachment of packed, and in a narrow sense the name is valid only in relation to the family of real frogs.
Description of frogs
Absolutely any representatives of frogs are distinguished by the lack of pronounced neck, and the head of such amphibians as if it struck with a short and large enough torso. The complete absence of tail in frogs is reflected directly in the title of the detachment, which unites all amphibians. It should be noted that the frogs have simply unique vision, so do not close the eyes during sleep, and also capable of looking forward, up and sideways at the same time.
Appearance
The frog has a big and flat head, on the side of which there are convex eyes.. Along with other terrestrial vertebral animals, frogs have the upper and lower eyelids. Under the lower age of the amphibian, a blissful membrane is found, which is called the "third century". Behind the eye of the amphibian is a special area, tightened with thin skin, called the eardrum. Two nostrils with special valves are located above a huge mouth with small sizes.
For the front paws of the frog characteristic of the presence of four rather short fingers. The rear paws of animal are strong and well developed, equipped with five fingers, the space between which is tightened by a special leather membrane. On the fingers of the animal there are no claws. The only output part is located in the rear area of \u200b\u200bthe frog body and is represented by the so-called clodium hole. A froggy body covers naked skin, sufficiently thickly lubricated with a special mucus, which is abundantly distinguished by special numerous subcutaneous glands of the animal.
It is interesting! The size of the frogs depend on the type, so the European frogs are most often no more than one decimeter, and African frog-goliaphs are a kind of record holders in terms of dimensions, therefore, with half-meter, weight, which makes up several kilograms.
The dimensions of the adult frog fluctuate depending on the species features, but most often vary from 0.8-32 cm. Color skin Pokrov is also very diverse and can be represented by brown, yellow, green or unusual restaining staining. Many family representatives prefer to disguise under herbaceous vegetation, foliage or branches, so they have skin of characteristic green, gray and grayish-green.
The combat color, as a rule, testifies to the poisonousness of the frog, which is explained by the presence on the skin of special glands that produce toxic and harmful to human health or animal substances. Some frogs easily mimic, foliating under dangerous amphibians to save from enemies.
Character and lifestyle
Frogs are able to move perfectly on land, as well as make just huge jumps, climb on the crown of tall trees and dig underground holes. For some species, the ability not only to swim is characteristic, but also run, walk, quickly climb on trees and even easily plan from height.
A very interesting features of frogs include the absorption of oxygen through the skin. This process is quite successfully carried out on land or in water, due to which the animal refers to the Amphibian category. Nevertheless, herbal European frogs known in our country are very widely known for water bodies only during the period of active breeding.
It is interesting! W. activity indicators different species And the subspecies are very different, so one of these amphibians prefers to hunt exclusively at night, but there are bright representatives who retain tirelessness of all twenty-four hours a day.
Interesting is the fact that the lungs are needed by frogs in order to publish rather loud and peculiar sounds, called quack. Sound bubbles and resonators help the amphibian of the widest range of sound, which is most often used to attract the opposite sex during the reproduction period.
Periodically, adult frogs drop their skin that is not necessary for the life of the amphibian animal by the body, after which they eat it in anticipation of the rustling of new skin. In terms of living, all real frogs are settled loners, inclined to short-term migration for small distances only during the reproduction period. Views that live in a temperate strip, with the onset of winter fall into hibernation.
How many frogs live
Unique animals, which are very bright representatives from the detachment of taped amphibians, have different duration Life. Her definition of B. natural conditions It is carried out by the method of skeletokronology, which makes it possible to correctly assess the individual growth rate and the offensive of puberty time.
It is interesting! According to scientists, a significant part of the frogs lives in nature no more than ten years, but numerous observations have shown that individual species and subspecies have life cycleconstituting thirty years.
Sexual dimorphism
Permanent and seasonal sexual dimorphism - a sign inherent in many amphibians, including some types of frogs. For some of the tree, it is characterized by an increase in the pillows of the fingers in males, which is used by amphibians when tapping on the ground and contributes to the actual attraction of females. The males of some species are distinguished by highly increased drumpipens. Seasonal dimorphism is determined by the presence of the so-called gonadotropic hormones in the body of the animal.
It is interesting! There are species, when visual inspection Which is impossible to determine the gender in accordance with only one feature, so it is necessary to compare several morphological characteristics at once.
One of the most vibrant and pronounced sexual characteristics that are peculiar to the males of frogs is represented by the formation of marriage pads as a response to changing the hormonal background of the seeds.
In the frog, such pads are formed on the lower part of the front limbs, on the fingers and near the mouth, due to which all the milk-crew males remain with the female in the paired state even with a strong water movement or other animals attack.
Types of frogs
To date, there are more than 550 species of amphibian animals, called frogs.. The family of real frogs is represented immediately by several submersions: African forest, discopal and zhabovoid, dwarf and real, as well as shielded frogs.
Many species are incredibly popular with the connoisseurs of indoor amphibians and are contained as exotic pets. Most interesting views Presented:
- dominican Kvakesh;
- australian quake;
- some elderly or;
- smooth shore frog or frog-aibolite;
- red-eyed Kvakesh;
- lake frog;
- a sharply frog;
- garlic.
The most unusual types of frogs are currently transparent or glass frog, poisonous frog Coca, hairy and flying frogs, bull frog, as well as a frog-clown and a sharp sawing frog.
It is interesting! Types may have significant differences in the structure. For example, wearlized frogs have flattened, as if the crushed body, and for frog-pigs, on the contrary, characterized by a bloated torso.
Area, habitats
Vertebral animals were distributed almost in all countries and continents, and even found in the conditions of Arctic snow. But the preference of the frog is given to the tropical forest zoneswhere there is just a huge variety of species and subspecies of such amphibians. Fresh reservoirs are predominantly frogs.
Real frogs are representatives of the family of fucking amphibians (Anura), which received almost widespread distribution, except South America, southern Australia and the territory of New Zealand. In our country, it is mostly herbal frog (Rana Temporaria) and pond frog (Rana Esculenta).
It should be remembered that the spread of some subspecies and types of frogs may well be limited to natural causes, including rivers, mountain ranges and deserts, as well as man-made factors represented by motorways and channels.
In tropical conditions, the variety of types of amphibious animals is much larger than in zones that differ cold or temperate climates. Separate species and subspecies of frogs are able to live even in salted waters or for the polar circle.
Diet frogs
Insectivore Frogs belong to the categories of predatory animals. Such amphibians with great pleasure emerge a large number of mosquitoes, as well as all sorts of butterflies and small invertebrate animals. Particularly large adult insectivorous individuals are not even more impressive in the size of the prey, which can be represented by some animal species of frogs and relatively small-sorted relatives.
It is interesting! Frogs of many species bring tremendous people. They are actively destroyed and the many harmful and dangerous worms for humans and plants, bugs and insects eaten.
Hunting for their victims is carried out by frogs with sticky and enough long tongueWhich deftly catches directly on the fly moshkaru, dragonflies, moths and other warded living creatures. Among the existing species and subspecies of frogs are also known uncomfortable amphibians, who are glad to use fruits or berries in food.
Pond, the lake frog refers to the class of amphibians. It has a body length of 7-10 centimeters. She is bright green with a brown tint. On the back there are dark spots and a white longitudinal strip, white abdomen.
The eyes of the frogs are bright golden. Spring near the ponds and swamps are heard their loud marriage concerts. These animals winter in the forest, swinging into a soft soil or in warm ponds. Already in the second half of April, when the air warms up to 8-10 degrees, the frogs begin the marriage games. The female puts the eggs on the bottom of the swamp or on the stalks of water plants. One frog can postpone from 400-1800 eggs. Of these, casuals of light olive or green color appear soon. Live frogs up to 12 years.
Pond, a lake frog feeds on insects. Its permanent menu consists of dragonfly larvae, mosquitoes, water beetles and mollusks. If the feed is not enough, then the frogs eat fry fishes and even the headastrics. Large frogs of this species sometimes attack small animals (voles, earthlings). Their prey can also be small birds, chicks and horrors. The frogs themselves also become objects of hunting for painted fish, reptiles, birds and mammals.
The frogs of this breed dwell in South and central Europe, in Central Asia and B. North Africa. They are found in the Crimea, in the Caucasus and Kazakhstan. This type of amphibious dwells in many areas of Russia.
Pond, lake frogs are often used in medicine, for experiments. They are edible, such a delicacy, like the frogs of the legs make exactly from this type of frogs. Also these animals play a considerable role in the natural food chain. Their caviar, casuals and they themselves serve as feed for many animals and fish.

Ostroordy frog
Pond frog
The skin of these animals is always wet, because Covered with mucus separated by skin glands. The color of the frogs can be the most diverse - from the brown-green to bright red. For frogs, two types of breathing are characterized - pulmonary and skin. On the land, the frog breathes with the help of the lungs, and under water turns to the skin breathing.
Spread
Frogs are found almost everywhere, the most types of frogs live in tropical forests.
Lifestyle
Frogs are active in the warm season. In Sunny hot weather They are sitting in the shade, and in rainy and cloudy weather willingly walk around the surroundings. With the onset of cold frogs hide in wet places, under the leaves or on the bottom of the reservoirs, can fall into the hibernation. Tropical frogs are active all year round.
Frog looks out of the water
Food
Frog hunting mosquito
Food frogs in main insects - beetles, midges, flies, mosquitoes, etc. But if you can eat and small fish, snail or spider. Frogs are hidden in water or on land and wait for their prey. With the appearance of a fly or another insect, the frog quickly throw out his sticky tongue, and the victim, sticking to it, goes right in the mouth. Frogs are hunting only on moving insects, they do not notice a fixed sacrifice and do not touch.
Frogs never drink water - the whole needed fluid comes to them into the body with food and through the skin.
Reproduction
With the onset of the period of reproduction, the frogs are collected near fresh reservoirs. The first comes males and loud quack begin to call for females. Hearing the squabs, females are also approaching the water. The lower and loud sounds Macing out the male, the more females responds to his call. When meeting with the male, the female postpones caviar. From the caviar goes from the frogs of the larvae, which are called "Golobastics". Golobastics are very different from adult frogs. They lead an exceptionally water lifestyle, breathe gill, they have no paw, but there is a tail. As a rule, thaws are powered by algae. After some time, metamorphosis occurs - the zhabras disappear from the headastrics and the lungs develop, the paws grow and disappears, the thaws turn into frogs.
Tadpole
Frog tomato
- In India, a purple frog lives, which almost all the time lives underground and only during the reproduction period goes to the surface.
- On the island of Madagascar lives a frog-tomato, her body is painted in bright red color.
- IN South Africa And in Madagascar you can meet unusual weary frogs, they can soar in the air, flying from a tree on a tree.
