Proboscis Monkey (Nasalis larvatus)

The largest of the old-world monkey species, the proboscis monkey is found only in Borneo. It feeds almost exclusively on the leaves and shoots of mangrove forest and coastal heath and swamp forests, and it has evolved a complex digestive system with a huge multi-chambered stomach to cope with this tough and fibrous diet.

Proboscis monkeys live in family groups of up to 12 females and one dominant male, while younger males live together in bachelor groups until they are ready to challenge anolder male for his harem. The huge nose is found only in males and, combined with the a huge pot belly and red fur, led to the proboscis monkey being nicknamed ‘Orang Belanda’ or the‘Dutchman’ by the people of Sarawak. The proboscis monkey is endangered due to destruction of its coastal habitat, as well as illegal hunting.
