Celebes apes are found only on the islands of Indonesia, mainly the island of Sulawesi. The hair of the celebes ape is mainly black except for a patch from the shoulder to the ilium and the combination of white and black hairs on the shoulders and upper arms.
Females tend to stay with the same group all their lives while males switch from group to group.
Since the females are permanent members, dominance within a particular group is determined by matrilines. Habitat The islands of Indonesia where celebes apes are found are moist and tropical with rich plant and animal life. The habitat of the celebes ape is constantly shrinking on this island due to an increase of human activity, which includes cultivation, logging, and catching and killing celebes apes. Until a few years ago, celebes apes were believed to exist only on the island of Sulawesi. In 1990, field studies showed that monkeys with characteristics similiar to that of the celebes apes were found on neighboring islands.
