Amphibian (biology)
Terragen vertebrate animals that spend the early part of their life cycle in water breathing through gills, but usually live on land as air-breathing adults. They include frogs, toads, newts, salamanders, caecilians, labyrinthodonts, and a number of other forms. The term may also be used to refer to equivalent xenobionts.
