Frogs: species, description.

The structure of all frogs is almost the same: they have a large head, bulging eyes, long hind legs and a wide mouth in which there are no teeth. The legs of these amphibians are equipped with swimming membranes, frogs do not have a tail. In addition to similar features, there are differences between members of the family. Depending on the species, frogs may have a characteristic body shape. For example, copepods have a flattened body, but in the case of frog-pigs, the body, on the contrary, is very swollen. In some representatives of the family, the muzzle has a blunt shape, in others it is oblong, even slightly elongated.

The skin of the frogs is very thin, it is always moistened with mucus, which is secreted by the body of the animal. Mucus is necessary to create a protective cover for the frog: it contains substances that kill pathogenic bacteria, and also heals wounds on the frog's body. Some representatives of the family of real frogs possess mucus endowed with toxic properties, such "weapons" are given to these animals to protect themselves from enemies. However, the representatives of real frogs do not specifically have deadly mucus, which cannot be said about their relatives - poison frogs.
