Habitats and lifestyle of amphibians.

The group of amphibians or amphibians consists of less than ten thousand species and is considered small in number. It includes primitive terrestrial vertebrates, which are rather intermediate between terrestrial and aquatic animals. Reproduction and development in most species occurs in the aquatic environment, and adults live on land. For example, the well-known frog. Actually, the name of the group – amphibians – already contains the answer to the question of where these organisms live. Their habitats are certainly tied to the reservoir, since some physiological processes (for example, reproduction) are impossible outside the aquatic environment.
