Species Directory. WWF is committed to saving endangered species. Learn more about the species we are working to protecting from becoming endangered or extinct.
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.
One million species globally are at risk of extinction in the next few decades, including 27 percent of the world’s mammals, 41 percent of amphibians, 37 percent of sharks and rays, and 21 percent of reptiles.
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:
View Our Species. We provide national leadership in the recovery and conservation of our nation's imperiled plant and animal species, working with experts in the scientific community to identify species on the verge of extinction and to build the road to recovery to bring them back.
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.
This list presents only a fraction of the species at risk of extinction today and does not include tens of thousands of species whose status we do not yet know. Species listed here range from the largest animal on Earth, the blue whale, to the majestic tiger, to the humble thickshell pondsnail.
An endangered species is a type of organism that is threatened by extinction. Species become endangered for two main reasons: loss of habitat and loss of genetic variation. Loss of Habitat. A loss of habitat can happen naturally. Nonavian dinosaurs, for instance, lost their habitat about 65 million years ago.
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.
Currently, there are more than 157,100 species on The IUCN Red List, with more than 44,000 species threatened with extinction, including 41% of amphibians, 37% of sharks and rays, 36% of reef building corals, 34% of conifers, 26% of mammals and 12% of birds.
