Gorilla
Gorillas are ground-dwelling, predominantly herbivorous apes that inhabit the forests of central Sub-Saharan Africa. They are classified in the genus Gorilla which 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 species of "Pan"; the chimpanzees and bonobos.
Tabin Wildlife Reserve
Tabin has been declared a wildlife reserve primarily on account of the large number of animals inhabiting its forests, some of which are highly endangered. The three largest mammals of Sabah – the Borneo elephant, Bornean rhinoceros (a subspecies of the Sumatran rhinoceros) and tembadau ("Bos javanicus"), are all found within the reserve. The elephant population has been estimated to 120-300 animals in 1993. Other ungulate species include sambar, muntjac and mouse deer. In addition seven of Sabah´s eight primate species are present, among them orangutan and proboscis monkey. However, these two species occur in relatively low numbers in the reserve. The biggest predator in the reserve is the Sunda clouded leopard. There are also several other smaller carnivores in the reserve. Of bird species, 42 families representing 220 species have been recorded.
