Endangered Primates
| More Primate Information Types of Animals Types of Monkeys |
The IUCN (International Union for Conservation of Nature and Natural Resources), a group of scientists, study and document primate species population levels noted in 2009 notes that "(48 percent) of the world's 634 primate species are classified as threatened with extinction".
In order to rank and compare the population stability of different species, IUCN specialists place them in various categories.
The most endangered primate species, those not already extinct, are categorized as critically endangered (endangered is the next ranking level). The twenty primate species listed as critically endangered are detailed here with their scientific name, common name, primate type, and geographical location.
The IUCN list changes as the scientists gather more information. If you are interested in additional information the The Primate Specialist Group is a great starting place.
