Lissamphibia
	The fire salamander
Scientific classification
Kingdom:	Animalia
Phylum:	Chordata
Subphylum:	Vertebrata
Superclass:	Tetrapoda
Class:	Amphibia
Subclass:	Lissamphibia; Haeckel, 1866

The subclass Lissamphibia includes all living amphibians. They are classified in three orders:

the Anura: frogs, including toads
the Caudata or Urodela: salamanders, including newts
the Gymnophiona or Apoda: the limbless caecilians.

Although the ancestry of each group is controversial, all share certain common characteristics. This indicates they evolved from a common ancestor and so form a clade.
