In the past, amphibians represented a very important group of animals, both because of the number of species that existed and because of the large body size they had. However, they were later evolutionarily overtaken by the reptiles, this group being reduced to a few categories.

Amphibians are estimated to have arisen from fish about 360 million years ago, and that the reptiles later developed from them, which in turn gave rise to the mammals and to the birds from the actuality.

In fact, they are the only vertebrates that suffer metamorphosis.

Classification of amphibians

There are three orders or classes of amphibians:

It is estimated that there are some 4,300 species of amphibians that live today, but by the way it is a biological group whose populations have been in clear regression of a time to this part, mainly due to the alteration of their natural habitat and climate change.
