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.
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.
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.
Endangered (EN) species are considered to be facing a very high risk of extinction in the wild. As of September 2021, the International Union for Conservation of Nature (IUCN) lists 1085 endangered amphibian species. [1] Of all evaluated amphibian species, 14% are listed as endangered. No subpopulations of amphibians have been evaluated by the ...
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.

The desert froglet, chirping froglet, or sparrow froglet (Crinia deserticola) is a species of frog in the family Myobatrachidae, endemic to Australia. Desert froglets occur mainly in dry or moist savanna habitats, principally from the mid-western border of Northern Territory, south-east into western Queensland and New South Wales and the north-east corner of South Australia.
