43% of World's Primates Endangered/Critically Endangered, Including Orang Species Defined In 2017

In 2017, the Tapanuli orangutan was discovered in the rainforests of Sumatra, Indonesia. The rust-colored beauties made headlines for becoming the eighth known species of great ape in the world (including us humans). Their discovery was also notable for being the first great ape species to be described to science since the bonobo was discovered in 1929.

Now, just two years later, the Tapanuli orangutan has been bestowed with a much more grim distinction: A spot in the new report, "Primates in Peril: The World’s 25 Most Endangered Primates, 2018-2020." With fewer than 800 of these new-to-science orangutans left in the wild, it's going to have to be all hands on deck to keep them from slipping away altogether.

Along with the Tapanuli orangutan, another six primate species from Asia made the list, as well as seven species from Africa, five from Madagascar, and six from the Neotropics. Primates include monkeys and apes, as many people know, but also counts lemurs, lorises, galagos, and tarsiers among its ranks.

The report is compiled by the IUCN SSC Primate Specialist Group, the International Primatological Society, Global Wildlife Conservation and the Bristol Zoological Society – it is a shout-out to the primates facing the most dire threats, as well as a call for conservation measures.
