Additionally 1193 amphibian species (16% of those evaluated) are listed as data deficient, meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, they are intrinsically likely to be threatened, according to the IUCN. [ 2 ]

The first version of the catalogue was published as a book in 1985, and well received by specialists in the field. [1] [2] In 1989, the ASC gave the copyright for Amphibian Species of the World to the Herpetologists' League, and they added more amphibians to the database. The League and American Museum of Natural History put Darrel Frost in ...
The world’s frogs, salamanders, newts and other amphibians remain in serious trouble. A new global assessment has found that 41% of amphibian species that scientists have studied are threatened ...
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 International Union for Conservation of Nature (IUCN) lists 35 extinct species, 146 possibly extinct species, two extinct in the wild species, and one possibly extinct in the wild species of amphibians. [1] [2]
This endangered cetacean is not only the smallest porpoise species, but the most rare. Where there were once thousands of vaquitas swimming in the sea, today there may only be about 10 individuals ...
