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 ]
