Proboscis Monkeys

The proboscis monkey (Nasalis larvatus) or long-nosed monkey, known as the bekantan in Malay, is a reddish-brown arboreal Old World monkey that is endemic to the south-east Asian island of Borneo, this species co-exists with the Bornean Orang-utan. It belongs in the monotypic genus Nasalis, although the pig-tailed langur has traditionally also been included in this genus.

The monkey also goes by the Malay name monyet belanda ("Dutch monkey"), or even orang belanda ("Dutchman"), as Indonesians remarked that the Dutch colonisers often had similarly large bellies and noses.

This species of monkey is easily identifiable because of its unusually large nose. The proboscis monkey is a large species, being one of the largest monkey species native to Asia. Males have a head-body length of 66 to 76.2 cm (26.0 to 30.0 in) and typically weigh 16 to 22.5 kg (35 to 50 lb), with a maximum known weight of 30 kg (66 lb). Females measure 53.3 to 62 cm (21.0 to 24.4 in) in head-and-body length and weigh 7 to 12 kg (15 to 26 lb), with a maximum known mass of 15 kg (33 lb). The large nose or proboscis of the male can exceed 10 cm (3.9 in) in length, and hangs lower than the mouth. Nevertheless, the nose of the female is still fairly large for a primate.
