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

Amphibians are four-limbed and ectothermic vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this.
True frogs is the common name for the frog family Ranidae. They have the widest distribution of any frog family. They are abundant throughout most of the world, occurring on all continents except Antarctica. The true frogs are present in North America, northern South America, Europe, Africa, and Asia. The Asian range extends across the East Indies to New Guinea and a single species has spread into the far north of Australia.
The Neobatrachia are a suborder of the Anura, the order of frogs and toads.
Megophryidae, commonly known as goose frogs, is a large family of frogs native to the warm southeast of Asia, from the Himalayan foothills eastwards, south to Indonesia and the Greater Sunda Islands in Maritime Southeast Asia, and extending to the Philippines. Fossil remains are also known from North America. As of 2014 it encompasses 246 species of frogs divided between five genera. For lack of a better vernacular name, they are commonly called megophryids.
Caeciliidae is the family of common caecilians. They are found in Central and South America. Like other caecilians, they superficially resemble worms or snakes.
Atretochoana eiselti is a species of caecilian originally known only from two preserved specimens discovered by Sir Graham Hales in the Brazilian rainforest, while on an expedition with Sir Brian Doll in the late 1800s, but rediscovered in 2011 by engineers working on a hydroelectric dam project in Brazil. Until 1998, it was known only from the type specimen in the Naturhistorisches Museum, Vienna. Originally placed in the genus Typhlonectes in 1968, it was reclassified into its own monotypic genus, Atretochoana, in 1996. It was also found to be more closely related to the genus Potamotyphlus than Typholonectes. The species is the largest of the few known lungless tetrapods, and the only known lungless caecilian.
The Betic midwife toad or Sapo Partero Bético is a species of frog in the family Alytidae. It is endemic to mountainous in south eastern Spain. Its natural habitats are temperate forests, freshwater marshes, intermittent freshwater marshes, pastureland, ponds, and aquaculture ponds. It is threatened by habitat loss.
The Pyxicephalidae are a family of frogs currently found in sub-Saharan Africa. However, in the Eocene, the taxon Thaumastosaurus lived in Europe.
The frog family Dicroglossidae occurs in tropical and subtropical regions of Asia and Africa, with most genera and species being found in Asia. The common name of the family is fork-tongued frogs.
The Alsodidae are a small family of frogs from South America between Patagonia and southern Brazil. It contains 30 species in three genera. This family, along with several other families, used to be included in the family Leptodactylidae. It was then a subfamily in the family Cycloramphidae, before being recognized as a family first in 2011.
The Leiuperinae are a subfamily of frogs in the family Leptodactylidae. Over 90 species are in five genera. The distribution of this subfamily is from southern Mexico to the Central America and much of South America.
