The eastern gorilla (Gorilla beringei) is a species of the genus Gorilla and the largest living primate. At present, the species is subdivided into two subspecies. The eastern lowland gorilla (G. b. graueri) is the most populous, at about 5,000 individuals. The mountain gorilla (G. b. beringei) has only about 700 individuals. In addition, scientists are considering elevating the Bwindi gorilla population (which numbers about half of the mountain gorilla population) to the rank of subspecies.
