Eastern gorilla
The eastern gorilla ("Gorilla beringei") is a critically endangered species of the genus "Gorilla" and the largest living primate. At present, the species is subdivided into two subspecies. Grauer's gorilla, formerly known as the eastern lowland gorilla ("G. b. graueri") is more populous, at about 3,800 individuals. The mountain gorilla ("G. b. beringei") has only about 1000 individuals. The International Union for the Conservation of Nature mentioned illegal hunting in its assessment of threats to the species.
International Primate Day
In 2016, Animal Defenders International (ADI) received a celebrity endorsement from Moby for their attempt to help the Barbary macaques for that year's event.
Primates are a very large family of about 200 species, include monkeys, bonobos, lemurs, orangutans, et al. Statements on great apes which focus largely or entirely on apes would not include all primates.
