Species diversity

An interesting fact about amphibians - they have minimal practical value, while there is still some benefit to humans - they destroy harmful arthropods, slugs and mollusks.

On our territory there are two groups:


This is the most numerous squad of amphibians. They live all over the planet, except for Antarctica and Australia.

Toads, frogs, frogs


There are about 280 species. All individuals are characterized by the presence of a developed tail section.

Tritons, salamanders

For some regions, eating frogs and salamanders is acceptable. Tritons feed on mosquito larvae, including malarial. Most often, frogs are experimented; on the other hand, they are also harmful because they are “lovers” of fry.

This is a commonly used concept of a whole order of tailless. In a narrow sense, this term is applicable to the family of true frogs. The minimum size of the animal is 9 mm, and the largest individuals can reach 90 cm, and they include the goliath frog. And the smallest lives in Cuba, its size is only 9 mm. All species of frogs have bulging eyes and a chunky body.

But few people know an interesting fact about amphibians - frogs have teeth, but they are intended solely for grasping and holding, but not for chewing. And toads have no teeth at all.

All frogs have a unique vision, being able to look in different directions with both eyes at the same time. These amphibians do not close their eyes for a long time, even when they sleep.

An interesting fact about amphibians - their skin has antibacterial and disinfecting properties, so in Russia it was decided to throw frogs into milk so that it does not turn sour.

There is such a thing as "functional necrophilia," this phenomenon occurs in Amazonian frog necrophilia. Males of this species are 10 times more than females, so they fertilize not only the eggs of living individuals, but also the dead. A caring frog bears her children in his own stomach until they fully mature. In practice, it looks like this - the female swallows the fertilized eggs, and as soon as they are ready to live independently, the frog spits them out.

Interesting facts about amphibians and amphibians:

  • There is a form like a glass frog, the skin on the belly resembles a glass surface through which all organs can be seen.
  • The most poisonous are leaf climbers and woodcutters. The poison of these amphibians is able to "knock" a large predator down.
  • Some species of frogs are able to remove foreign objects from their bodies. This foreign object is practically overgrown with "meat", enters the bladder and is removed from there.

Humankind also treats these animals differently, for example, in Japan and France they were immortalized in monuments. And in restaurants in Peru, a cocktail is served, in which one of the ingredients is a live frog. According to the assurances of the local population, this drink can improve potency and get rid of asthma.

This is the general name of the family of the order caudate. This term does not have any systemic binding, water individuals are called “tritons” for those individuals that live primarily in water, and terrestrial are called salamanders. Interesting facts - the class of amphibians is often confused with lizards, which inherently belong to the order of reptiles.

Only three types live in our country:

  • comb;
  • ordinary;
  • Asia Minor.

These amphibians have a beautiful dorsal ridge, and the belly is yellow or orange. The female has to carefully hide her offspring. If there is no secluded place in the pond nearby,then she wraps the eggs in the leaves and only then drops them in the water. An interesting fact about amphibians - tritons are able to grow a lost limb. If severe cold occurs, some individuals can practically grow into the ice, and in the spring they can live, as before, without any damage to their health. In severely dry periods, the triton almost dries out, but after the first rain it is instantly restored.


In our country, the most common type is the fire salamander. They have bright spots on their bodies, and poisonous liquid is released from the glands around the eyes. If it gets on the mucous membrane of a person, it will inevitably cause a burning sensation.

An interesting fact is that tailed amphibians do not like the cold, so for the winter they come together in large groups, near the roots under a huge layer of fallen leaves. In the cold amphibians practically do not move.

The largest individuals are found in the waters of East China, called this species - the giant salamander. It can weigh about 70 kg, and in length reach 2 meters.

Previously it was believed that salamanders are poisonous, in fact, poison, which is released from the glands around the eyes, can only paralyze the victim for some time or cause her heart arrhythmia.But even with the presence of poison on this amphibian, some fish, birds, and even wild boars hunt. The salamanders themselves consume insects, but do not disdain small tritons and frogs.

An interesting fact - this class of amphibians swims very poorly, and even in deep water can even drown. Therefore, they need water exclusively for laying eggs.

This is the least studied amphibian, but there are about 100 species of worms. This animal lives underground, although it can exist on land and in water. Interesting facts about amphibians - the worm has no eyes, very poor hearing, but a magnificent scent. Mostly all species have a dark color, but there are blue and yellow. Amphibians eat molluscs and earthworms, live mainly in tropical forests.

To date, amphibians or amphibians are on the verge of extinction. They are too dependent on water, are small and permeable skin. The most part is under direct anthropogenic human influence. Another danger for amphibians is chytradiomycete fungi, the abundant growth of which is associated with an increase in atmospheric temperature on the planet.
