Critically Endangered
Celebes crested macaque
Macaca nigra
The Celebes crested macaque, also known as the crested black macaque, Sulawesi crested macaque, or the black ape, is an Old World monkey that lives in the tropical regions of north Sulawesi.
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.
