Amphibian (Amphibia) ...
From Wikipedia, the free encyclopedia

Amphibians (class Amphibia), such as frogs, toads, salamanders, newts, and caecilians, are ectothermic (or cold-blooded) animals that either metamorphose from a juvenile water-breathing form, to an adult air-breathing form, or paedomorph and retain some juvenile characteristics. Mudpuppies and waterdogs are good examples of paedomorphic species. Though amphibians typically have four limbs, the caecilians are notable for being limbless. Unlike other land vertebrates (amniotes), amphibians lay eggs in water. Amphibians are superficially similar to reptiles.
