As of December 2021, the International Union for Conservation of Nature (IUCN) lists 673 critically endangered amphibian species, including 146 which are tagged as possibly extinct. [1] [2] 9.2% of all evaluated amphibian species are listed as critically endangered. No subpopulations of amphibians have been evaluated by the IUCN.
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 ]
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.

In Vietnam and Laos, the species' range appears to cover approximately 5,000 km 2 (1,900 sq mi), including four nature reserves. During the winters, it migrates to the lowlands. [ 20 ] In the northern Annamite Mountains , it was sighted mostly near streams at elevations of 592–1,112 metres (1,942–3,648 ft).
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.

A type of leaf-eating langur that has an unusually long and bushy tail with white hips. It is also one of the most endangered primates in the world. Only about 300 Delacour's langurs are alive today, and experts fear they could be completely extinct if the current rate of decline continues.
