One of the orders of the class Amphibia, comprising the salamanders. The taxon class Amphibia comprises the Lissamphibia (all modern amphibians, including frogs, toads, salamanders, and caecilians) and their more distant extinct relatives. The members of the order Urodela (also termed Caudata in some classifications) are the tailed amphibians, or salamanders (Fig. 1). They are distinguished superficially from the frogs and toads (order Anura) by the possession of a tail, and from the caecilians (order Apoda) by the possession of limbs. See also: Amphibia; Anura; Apoda; Lissamphibia
