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.
The mountain gorilla (Gorilla beringei beringei) is one of the two subspecies of the eastern gorilla. There are two populations. One is found in the Virunga volcanic mountains of Central Africa, within three National Parks: Mgahinga, in south-west Uganda; Volcanoes, in north-west Rwanda; and Virunga in the eastern Democratic Republic of Congo (DRC).
The western gorilla (Gorilla gorilla) is a great apeāthe type species as well as the most populous species of the genus Gorilla.
The Western lowland gorilla is the only subspecies kept in zoos with the exception of Amahoro, a female Eastern lowland gorilla at Antwerp Zoo and a few Mountain gorillas kept captive in Democratic Republic of the Congo.
