Amphibians Class Characterization

Amphibians are cold- blooded animals that have features between fish and reptiles. They live both on land and in water. Their larvae develop in water breathing through gills, once they mature they begin to breathe through lungs and skin. Amphibians lay eggs but the eggs don't have a shell or an amniotic membrane that surrounds the embryo.

Characterization Benefits

Amphibians being cold- blooded means that they don't have a regular body temperature, they take on the temperature of their environment. During hot and dry weather they go into a state of hibernation called estivation. They are also mostly found near freshwater because if their skin dries out they will die.
