Appearance

Locally known as yaki, wolai, or bolai, its skin and hairless face is, with the exception of some white hair in the shoulder range, entirely jet black. It has a long muzzle with high cheeks, a long hair tuft, or crest, at the top of the head and striking reddish-brown eyes, unusual for a primate.

Uniquely among macaques, males and young females bear a heart-shaped skin pad on the rump.Although possessing a markedly ape-like appearance, it has an almost non-existent, non-visible, vestigial tail stub of only approximately 2 cm (0.8 in).

Range and habitat

Celebes crested macaque has around eight subpopulations, with a introduced population on the island of Bacan. M. Nigra seems to prefer closed canopy forests, with the occupancy being higher along with protected areas.
