Eastern gorilla
There are two recognised subspecies of eastern gorilla: the mountain gorilla ("Gorilla beringei beringei") of the volcanic slopes of Rwanda, Uganda and eastern Democratic Republic of Congo; and Grauer's gorilla or eastern lowland gorilla ("Gorilla beringei graueri") in eastern Democratic Republic of Congo.
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.
