Orangutan [Pongo pygmaeus] eating banana's in Tanjung Puting NP Borneo
The Proboscis Monkey (Nasalis larvatus), also known as the Monyet Belanda (in Malay), the Bakantan (in Indonesian) or simply the Long-nosed Monkey, is a reddish-brown arboreal Old World monkey that is endemic to the south-east Asian island of Borneo. A distinctive trait of this monkey is the male's large protruding nose, from which it takes its name. The nose is thought to be used in mating and is unique to the males of the species, reaching up to 7 inches in length. Besides attracting mates, the nose serves as a resonating chamber and works by amplifying their warning calls. When the animal becomes agitated its nose swells with blood, making warning calls louder and more intense. Males are much larger than females, reaching 72 cm (28 inches) in length, with an up to 75 cm tail, and weighing up to 24 kg (53 pounds). Females are up to 60 cm long, weighing up to 12 kg (26 lb). This large sexual dimorphic difference is greater than in any other primate. The Proboscis Monkey also has a large belly, as a result of its diet. The diet consists mainly of seeds, leaves, mangrove shoots and unripe fruit. The Proboscis Monkey is endemic to Borneo's low elevation mangrove forests, swamps, and lowland riparian forests. It lives in small groups of 10 to 32 animals. Group membership is very flexible, and animals are known to move from group to group quite often. The Proboscis Monkey lifestyle is both arboreal and amphibious, with its mangrove swamp and riverine environment containing forest, dry land, shallow water allowing wading, and deep water requiring swimming. Like other similar monkeys, the Proboscis Monkey climbs well. Due to ongoing habitat loss and hunting in some areas, only about 7000 are known to still exist in the wild. In Sarawak, the population of this species has declined from 6500 in 1977 to only 1000 in 2006. The Proboscis Monkey is evaluated as Endangered on the IUCN Red List of Threatened Species. It is listed on Appendix I of CITES.
