List of critically endangered mammals

As of January 2020, the International Union for Conservation of Nature (IUCN) lists 203 critically endangered mammalian species, including 31 which are tagged as possibly extinct.1 [1][2] 3.5% of all evaluated mammalian species are listed as critically endangered. The IUCN also lists 60 mammalian subspecies as critically endangered.

203 critically endangered mammalian species (3.5%)505 endangered mammalian species (8.7%)536 vulnerable mammalian species (9.3%)345 near threatened mammalian species (6.0%)3306 least concern mammalian species (57%)872 data deficient mammalian species (15%)

Mammalian species (IUCN, 2020-1)
  • 5850 extant species have been evaluated
  • 4978 of those are fully assessed[lower-alpha 1]
  • 3651 are not threatened at present[lower-alpha 2]
  • 1244 to 2116 are threatened[lower-alpha 3]
  • 81 to 83 are extinct or extinct in the wild:
    • 81 extinct (EX) species[lower-alpha 4]
    • 2 extinct in the wild (EW)
    • 0 possibly extinct [CR(PE)]
    • 0 possibly extinct in the wild [CR(PEW)]
  1. excludes data deficient evaluations.
  2. NT and LC.
  3. Threatened comprises CR, EN and VU. Upper estimate additionally includes DD.
  4. Chart omits extinct (EX) species
Critically Endangered (CR) species face an extremely high risk of extinction in the wild.

Of the subpopulations of mammals evaluated by the IUCN, 18 species subpopulations have been assessed as critically endangered.

Additionally 900 mammalian species (15% 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.[3] While the category of data deficient indicates that no assessment of extinction risk has been made for the taxa, the IUCN notes that it may be appropriate to give them "the same degree of attention as threatened taxa, at least until their status can be assessed."[4]

This is a complete list of critically endangered mammalian species and subspecies evaluated by the IUCN. Species considered possibly extinct by the IUCN are marked as such. Species and subspecies which have critically endangered subpopulations (or stocks) are indicated. Where possible common names for taxa are given while links point to the scientific name used by the IUCN.
