Amphibian animals are now
amphibians
The amphibians, now named
amphibians, the most known are frogs, toads, salamanders ... they are not
reptiles. In fact, amphibians existed before reptiles. Reptiles come from a
branch of prehistoric amphibians. They are amphibians, so they can live in the
water and on the land, but there are exceptions.
One of the differences between
amphibians and reptiles is their skin and the lack of claws in the amphibian.
The skin of reptiles is made of scales, but the skin of a batrachian is smooth.
The amphibians have a permeable skin that lets liquids and air through, so they
need a moist environment to not dry. Since they breathe and exchange fluids
easily through the skin, they are more affected by pollution.
For reproduction, the majority
of amphibians lay their eggs in the water. The eggs are gelatinous but have no
shell like that of reptiles and can not withstand the terrestrial environment
unless it is very wet, or laid under the ground.
The amphibians can be
oviparous, viviparous and ovoviviparous which means that some lay eggs, some
give small well trained or they can have small formed in an envelope a bit like
an egg. The sudden majority of important metamorphoses, such as the tadpole,
and others more minor.

A batrachian is a cold-blooded
animal, so it is influenced by temperature and its slowed metabolism when it
becomes colder. Frogs often spend the winter under a rock or a dead branch, its
metabolism very slow, then resumes its activities when spring arrives.
The amphibians feed on insects
and other animals smaller than themselves. Many have a very long tongue that
they use to catch their prey from a good distance, which makes feeding easier.
