Description

The proboscis monkey (Nasalis larvatus) is an arboreal Old World monkey with a huge nose, reddish-brown skin, and a long tail. It's indigenous to Borneo and found in mangrove forests and coastal locations. The proboscis monkey is a huge Asian monkey. The Tibetan macaque and a few grey langurs are bigger. Sexual dimorphism is prominent. Males have a head-body length of 66 to 76.2 cm (26.0 to 30.0 in) and weigh 16 to 22.5 kg (35 to 50 lb) (66 lb). Females are 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) (33 lb). The male's huge snout or proboscis can surpass 10.2 cm (4.0 in) and hangs lower than the mouth. The long nose may be due to sexual selection by females who favour louder vocalisations, with the nose enhancing the call volume. Female's nose is huge for a primate. The proboscis monkey's back fur is orange, reddish brown, yellowish brown, or brick-red. Underfur is light-grey, yellowish, or greyish-to-orange. Blue babies' faces turn grey around 2.5 months. By 8.5 months, the face is cream-colored like adults. Male has crimson penis and black scrotum. Both sexes have potbelly tummies. Monkey toes are webbed. Proboscis monkeys live in groups including a male, some females, and their young. All-male bands exist. Some men are alone. Monkey groups dwell in overlapping home ranges with low territoriality, gathering at sleeping places at night. Bands form when groups combine and break away, although sometimes they mate and groom.
