What Animals Are on the Brink of Extinction?

The Red List Assessment

The International Union for Conservation of Nature (IUCN) has assessed over 41,000 species and found that more than 41,000 are threatened with extinction. The IUCN Red List is the world's most comprehensive information source on the global conservation status of animal, plant, and fungus species. It provides an objective measure of the risk of extinction facing species that can inform policy makers and guide conservation action.
