Gorilla gina; Print; Gorillas are ground-dwelling; predominantly herbivorous apes that inhabit the forests of central Sub-Saharan Africa. The 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 95 to 99% depending on what is included; and they are the next closest living relatives to humans after the chimpanzees and bonobos.; 1859
