An Amphibian is among the first of the Tetrapoda taxon, they include Apoda; Caecilians and Lissamphibia, Urodela, which are the salamanders, and Anura, which are frogs and toads. They have a latteral line system but only in the young. Their eggs do not have an outer casing. Most amphibians do not have nares, or nose openings, but instead breathe through their skin, due to capullaries on the skin. Anurans have a Tympanum, which is an external ear drum.
