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).
The number of known amphibian species is approximately 8,000, of which nearly 90% are frogs. The smallest amphibian (and vertebrate) in the world is a frog from New Guinea (Paedophryne amauensis) with a length of just 7.7 mm (0.30 in).
Active. Amphibian Species of the World 6.2: An Online Reference (ASW) is a herpetology database. It lists the names of frogs, salamanders and other amphibians, which scientists first described each species and what year, and the animal's known range. The American Museum of Natural History hosts Amphibian Species of the World, which is updated ...
Researchers evaluated the health of more than 8,000 amphibian species around the world and determined that nearly 41% — 2,871 in total — are globally threatened. The number of threatened ...
AmphibiaWeb's goal is to provide a single page for every species of amphibian in the world so research scientists, citizen scientists and conservationists can collaborate. [1] It added its 7000th animal in 2012, a glass frog from Peru. [2] [3] As of 2022, it hosted more than 8,400 species located worldwide. [4] [5]
The muscles have also been greatly enlarged, with the main leg muscles accounting for over 17% of the total mass of frogs. [53] Many frogs have webbed feet and the degree of webbing is directly proportional to the amount of time the species spends in the water. [54]
Declines in amphibian populations were first widely recognized in the late 1980s [citation needed], when a large gathering of herpetologists reported noticing declines in populations in amphibians across the globe. [6] Among these species, the golden toad (Bufo periglenes) endemic to Monteverde, Costa Rica, featured prominently.
First detected in Australia and Central America in the 1990s, the fungus caused mass mortality and population declines of frogs and other amphibians around the world. “Those were really dark ...
