Gorontalo Macaque

The Gorontalo macaque[1] (Macaca nigrescens), also called the Dumoga-bone macaque, is a species of the primate of the Cercopithecidae family.

  • It is native to the Sulawesi Island of Indonesia. Gorontalo macaques are large diurnal primates with black bodies and faces.
  • Their faces are black and sparsely covered with fur, and their fur is coarse, dense, and shaggy.
  • Juvenile Gorontalo macaques are paler than adults and appear brown instead of black. In addition, juveniles have black fur where the crest develops.
  • As adult male species age, their hair turns grizzled and gray, most noticeable on the upper body; it also sometimes occurs in the arms of younger men.

  • Female species have an egalitarian social structure, while men form a linear and transitive domination hierarchy.
  • Groups are typically tolerant, characterized by displays of appeasement, minimal aggression (biting), and “symmetry in conflict“.
