Currently, on the International Union for Conservation of Nature (IUCN) red list, more than 41,000 species have been assessed to be under threat of extinction. And below we’ve listed 10 of the world’s most endangered animals in the wild:
The species under the index include: mammals, birds, amphibians, cycads, and corals. Those species of "Near Threatened" (NT) and "Least Concern" (LC) status have been assessed and found to have relatively robust and healthy populations, though these may be in decline.

Established in 1964, The International Union for Conservation of Nature’s Red List of Threatened Species has evolved to become the world’s most comprehensive information source on the global conservation status of animal, fungi and plant species.
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological species.
The IUCN Red List of Threatened Species™ is the world’s most comprehensive information source on the global extinction risk status of animal, fungus and plant species. Open to all, it is used by governmental bodies, non-profit organisations, businesses and individuals.
These tables include number of species tagged as 'Possibly Extinct' (CR (PE)) and 'Possibly Extinct in the Wild' (CR (PEW)). These figures are included to give an upper estimate for total number of recently extinct species on The IUCN Red List.
Figure 1: The Red List Index (RLI) of species survival for mammals, birds, amphibians, reef-forming corals and cycads. The blue line indicates the overall RLI for all the taxa combined (Aggregate). Coral species are moving towards increased extinction risk most rapidly, while amphibians are, on average, the most threatened animal group.
