amphibian, adjective

amphibian

a member of the vertebrate class Amphibia, containing frogs, toads, newts, salamanders and the burrowing caecilians. Descended from fish-like animals, they colonized the land in the late DEVONIAN PERIOD. They are thought to be the immediate ancestors of the reptiles, though present-day amphibians are little like their Devonian ancestors. Most amphibians, although normally terrestrial animals, return to water during the breeding season. Fertilization is external (the eggs lacking a shell and embryonic membranes), and the eggs are usually laid and develop in water.
