WWF is committed to saving endangered species. Learn more about the species we are working to protecting from becoming endangered or extinct.
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.The hot, dry climate of the Cretaceous period changed very quickly, most likely because ...
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 IUCN Red List is a critical indicator of the health of the world’s biodiversity. Far more than a list of species and their status, it is a ...
Today, these tree-dwelling primates are critically endangered with fewer than 800 individuals in the wild, making them the most endangered great ape species in the world. The loss of habitat is one of the main threats to its survival as tropical forests are being replaced by agriculture, mining, and hydroelectric and geothermal development.
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching, invasive species, and climate change.
Jul 18, 2024 · Endangered species, any species that is at risk of extinction because of a sudden rapid decrease in its population or a loss of its critical habitat. Previously, any species of plant or animal that was threatened with extinction could be called an endangered species.
Species are classified into one of nine Red List Categories: Extinct, Extinct in the Wild, Critically Endangered, Endangered, Vulnerable, Near Threatened, Least Concern, Data Deficient and Not Evaluated. Vulnerable, Endangered and Critically Endangered species are considered to be threatened with extinction.
The bad news, however, is that biodiversity is declining. Currently, there are more than 163,000 species on The IUCN Red List, with more than 45,300 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. Despite the high proportions ...

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.
