Tonkean Black Macaque

The Tonkean black macaque or Tonkean macaque (Macaca tonkeana) is a species of primate in the family Cercopithecidae. It is endemic to central Sulawesi and the nearby Togian Islands in Indonesia. It is threatened by habitat loss. Widespread mining in central Sulawesi is believed to exacerbating the problems of habitat loss.
Tonkean macaques have an ape-like appearance, with males being slightly larger than females. A handful of matriarchs enforce a relatively lenient, though stable, pecking order. These macaques take significant effort in maintaining harmony within the group and practice conflict resolution to a great degree. However, this peacefulness does not extend to outside troops. If two tonkean macaque troops cross paths, intense conflicts can arise. [1]
