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 Neobatrachia comprise the most modern species of frogs. Most of these frogs have morphological features which are more complex than those of the mesobatrachians and archaeobatrachians. The neobatrachians all have a palatine bone, which braces the upper jaw to the neurocranium. This is absent in all Archaeobatrachia and some Mesobatrachia.

Some 50 to 100 extant species are now placed in this genus by various authors; many other species formerly placed in Rana are now placed elsewhere. Frost [3] restricted Rana to the Old World true frogs and the Eurasian brown and pond frogs of the common frog R. temporaria group, [4] although other authors disagreed with this arrangement.
A few species deposit eggs on land or bypass the tadpole stage. Adult frogs generally have a carnivorous diet consisting of small invertebrates, but omnivorous species exist and a few feed on plant matter. Frog skin has a rich microbiome which is important to their health. Frogs are extremely efficient at converting what they eat into body mass.
As of September 2016, the International Union for Conservation of Nature (IUCN) lists 402 near threatened amphibian species. [1] 6.2% of all evaluated amphibian species are listed as near threatened. No subpopulations of amphibians have been evaluated by the IUCN. This is a complete list of near threatened amphibian species evaluated by the IUCN.
Brachycephaloidea (Terrarana) is a monophyletic group of frogs that includes the families: Brachycephalidae, Caligophrynidae, Craugastoridae, Eleutherodactylidae, Ceuthomantidae, Neblinaphrynidae and Strabomantidae.
