A list of amphibians organizes the class of amphibian by family and subfamilies and mentions the number of species in each of them.
The list below largely follows Darrel Frost's Amphibian Species of the World (ASW), Version 5.5 (31 January 2011). Another classification, which largely follows Frost, but deviates from it in part is the one of AmphibiaWeb, which is run by the California Academy of Sciences and several of universities. The major differences between these two classifications are:
Frost's ASW has split several families from other families (i.e. elevated to distinct families), whereas AmphibiaWeb has not (i.e., keeping them within the original families as subfamilies):
AmphibiaWeb has also split a few families off from other families (i.e. elevated to distinct families), where Frost's ASW has not (i.e., keeping them within the original families):
Family Alytidae – painted frogs or disc-tongued frogs, 12 species. Includes the genus Discoglossus (5 species) which is sometimes considered a distinct family, Discoglossidae.
Family Ambystomatidae – mole salamanders, 37 species. The Pacific mole salamanders of genus Dicamptodon (4 species) are considered a distinct family, Dicamptodontidae, by AmphibiaWeb:
Family Amphiumidae – amphiumas or Congo eels, 3 species
Family Plethodontidae – lungless salamanders, 488 species
