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.

This is a list of amphibians of Europe. It includes all amphibians currently found in Europe . It does not include species found only in captivity or extinct in Europe , except where there is some doubt about this, nor does it currently include species introduced in recent decades.
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.
Frog populations have declined dramatically since the 1950s. More than one-third of frog species are considered to be threatened with extinction, and more than 120 species are believed to have become extinct since the 1980s. [202] Among these species are the gastric-brooding frogs of Australia and the golden toad of Costa Rica.
Over 40 species are currently recognised. [1] These frogs have long toes with strong webbing between them, enabling the animals to jump from tree to tree, using the webbing to control a gliding descent, a form of arboreal locomotion known as parachuting. [2] This behavioral adaptation is the source of their common name, "flying frogs".
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.
