In 2008, the most comprehensive assessment of the world’s mammals has confirmed an extinction crisis, with almost one in four at risk of disappearing forever, according to the IUCN Red List of Threatened Species. Since then the situation has worsened.
The IUCN Red List of Threatened Species (version 2021-3) shows that at least 1335 of the 5968 mammal species on Earth are known to be threatened with extinction. According to the IUCN at least 85 mammal species and 12 mammal subspecies have become extinct since the year 1500. Besides that, 2 mammal species are considered extinct in the wild and survive only in captivity.
However, the real situation could be much worse, as 31 mammal species are listed as Critically Endangered (Possibly Extinct) and 840 mammal species as Data Deficient. As information improves, more mammals may well prove to be in danger of extinction or already extinct.
