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 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).
Amphibians are in decline worldwide, with 2 out of every 5 species threatened by extinction, according to a paper published Wednesday in the scientific journal Nature. More than 2,000 species of ...
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]
More than 99 percent of all species, amounting to over five billion species, [7] that ever lived on Earth are estimated to be extinct. [8] [9] Estimates on the number of Earth's current species range from 10 million to 14 million, [10] of which about 1.2 million have been documented and over 86 percent have not yet been described.
