{{Taxobox | name = Lissamphibia | image = Salamandra salamandra (Marek Szczepanek).jpg | image_width = 230px | image_caption = The [[fire salamander]] | regnum = [[Animal]]ia | phylum = [[Chordate|Chordata]] | subphylum = [[Vertebrata]] | superclassis = [[Tetrapoda]] | classis = [[Amphibia]] | subclassis = '''Lissamphibia''' | subclassis_authority = [[Ernst Haeckel|Haeckel]], 1866 | subdivision_ranks = Orders | subdivision = [[Anura]]<br/> [[salamander|Caudata]]<br/> [[caecilian|Gymnophiona]] }} The [[subclass]] '''Lissamphibia''' includes all living [[amphibia]]ns. They are [[biological classification|classified]] in three [[Order (biology)|orders]]: *the [[Anura]]: [[frog]]s, including [[toad]]s *the [[Caudata]] or Urodela: [[salamander]]s, including [[newt]]s *the [[Gymnophiona]] or Apoda: the limbless [[caecilian]]s. Although the ancestry of each group is controversial,<ref>Carroll, Robert 2009. ''The rise of amphibians: 300 million years of evolution''. Johns Hopkins University Press. ISBN 978-0-8018-9140-3</ref> all share certain common characteristics. This indicates they evolved from a common ancestor and so form a [[clade]]. == References == {{reflist}} {{-}} {{biology-stub}} {{wikispecies|Lissamphibia}} [[Category:Amphibians]]
