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 ]
The Mississippi gopher frog is among rarest amphibians in North America, if not the rarest. [8] There were two known places of the Mississippi gopher frog. They were Glen's Pond at Harrison County, Mississippi, and Mike's Pond at Jackson County, Mississippi. Scientists discovered a population of Mississippi gopher frogs at Mike's Pond in 2004.

Chinese giant salamanders for sale in a restaurant in Hongqiao Town (虹桥镇) in Zhejiang, China for 880 CNY/jin, or about 215 EUR/kg or US$127/lb. Such prices make them an attractive target for poaching. [41] In the past, the Chinese giant salamander was fairly common and widespread in China. [1]

The recent change in its conservation category in IUCN from Vulnerable to Endangered, arose from the Chile's amphibian reevaluation workshop for the Red List (Soto-Azat et al., 2015). The justification for its current category is due to its limited occupation area (estimated at 264 km2), severe fragmentation of its populations and continued ...
