As of 2022, the International Union for Conservation of Nature (IUCN) listed 40 animal species as extinct in the wild. [1] That is approximately 0.04% of all evaluated animal species. The IUCN also lists five animal subspecies as extinct in the wild. This is a complete list of wild animal species and subspecies listed as extinct by the IUCN.
This page features lists of species and organisms that have become extinct. The reasons for extinction range from natural occurrences, such as shifts in the Earth's ecosystem or natural disasters, to human influences on nature by the overuse of natural resources, hunting and destruction of natural habitats.
The infraorder Pinnipedia consists of 3 families containing 34 extant species belonging to 22 genera and divided into 48 extant subspecies, as well the extinct Caribbean monk seal and Japanese sea lion species, which are the only pinniped species to go extinct since prehistoric times. This does not include hybrid species or extinct prehistoric ...
Specific targeting of one species can be problematic to the ecosystem because the sudden demise of one species can inadvertently lead to the demise of another (coextinction) especially if the targeted species is a keystone species. Sea otters, for example, were hunted in the maritime fur trade, and their drop in population led to the rise in ...
Amphibian species (IUCN, 2016-2) 6492 extant species have been evaluated; 4925 of those are fully assessed [a] 2860 are not threatened at present [b] 2063 to 3630 are threatened [c] 35 to 148 are extinct or extinct in the wild: 33 extinct (EX) species [d] 2 extinct in the wild (EW) 113 possibly extinct [CR(PE)] 0 possibly extinct in the wild ...
One canid, the domestic dog, entered into a partnership with humans at least 14,000 years ago and today remains one of the most widely kept domestic animals. [4] The 13 extant genera and 37 species of Caninae are primarily split into two tribes: Canini, which includes 11 genera and 19 species, comprising the wolf-like Canina subtribe and the ...
Invertebrate species (IUCN, 2020.1) 17,646 extant species have been evaluated; 12,368 of those are fully assessed [a] 8024 are not threatened at present [b] 4328 to 9606 are threatened [c] 410 to 616 are extinct or extinct in the wild: 395 extinct (EX) species [d] 15 extinct in the wild (EW) 206 possibly extinct [CR(PE)] 0 possibly extinct in ...
It is the study of extant taxa (singular: extant taxon): taxa (such as species, genera and families) with members still alive, as opposed to (all) being extinct. For example: For example: The Indian elephant ( Elephas maximus ) is an extant species, and the woolly mammoth ( Mammuthus primigenius ) is an extinct species.
