This family is also known as the âGreat Apeâ family, and also includes three other types of primate: orangutans, chimpanzees, and humans. There are two species of gorilla: the Eastern Gorilla, and the Western Gorilla.
Gorillas are ground-dwelling, predominantly herbivorous apes that inhabit the forests of central Africa. The eponymous genus Gorilla is divided into two species: the eastern gorillas and the western gorillas (both critically endangered), and either four or five subspecies. They are the largest living primates. The DNA of gorillas is highly similar to that of humans, from 95â99% depending on what is counted, and they are the next closest living relatives to humans after the chimpanzees and bonobos. Gorillas' natural habitats cover tropical or subtropical forests in Africa.
