Cold-blooded vertebrates that typically begin life as aquatic, gill-breathing larvae before metamorphosing into an adult form better suited to life on land, though many species depart from this pattern. Amphibia includes frogs and toads, salamanders and newts, and the limbless, burrowing caecilians, and its permeable skin makes the class an especially sensitive indicator of environmental pollution.
