Amphibians

just for fun!

Amphibians evolved from fish about 400 million years ago, when the amount of dry land on Earth increased greatly.

Amphibians are cold-blooded animals that have backbones and display features that lie between those of fish and reptiles. They spend time both in water and on land.

Amphibians are cold-blooded animals who:-take on the temperature of their environment.-have moist scaleless skin that absorbs water and oxygen.-need a moist environment or they will dry out and die.- are most often found near ponds, marshlands, swamps, and other areas where freshwater is available.
