Critically Endangered

An IUCN Red List Critically Endangered (CR or sometimes CE) species is one that has been categorized by the International Union for Conservation of Nature as facing an extremely high risk of extinction in the wild. As of December 2023, of the 157,190 species currently on the IUCN Red List, 9,760 of those are listed as Critically Endangered, with 1,302 being possibly extinct and 67 possibly extinct in the wild.

The IUCN Red List provides the public with information regarding the conservation status of animal, fungi, and plant species. It divides various species into seven different categories of conservation that are based on habitat range, population size, habitat, threats, etc. Each category representing a different level of global extinction risk. Species that are considered to be Critically Endangered are placed within the "threatened" category.

As the IUCN Red List does not consider a species extinct until extensive, targeted surveys have been conducted, species that are possibly extinct are still listed as Critically Endangered. IUCN maintains a list of "possibly extinct" and "possibly extinct in the wild" species, modeled on categories used by BirdLife International to categorize these taxa.

Reference:
A conservation status category is assigned to each species that predict how likely it is that it will become extinct in the near future. Most designations are labeled in wikipedia, the main source of this data, which got its information from two main sources: 1) The IUCN Red List of Threatened Species by the International Union for Conservation of Nature, and 2) The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).
