Tonkean macaque

The Tonkean black macaque or Tonkean macaque (Macaca tonkeana) is a primate of the family Cercopithecidae. It is endemic to central Sulawesi and the nearby Togian Islands in Indonesia. Its diet is composed mostly of fruit, so it counts as frugivorous, and it eats ripe fruit of the fig and mulberry family in particular. The species is threatened by habitat loss, and widespread mining in central Sulawesi is believed to be worsening that loss. Social life in the Tonkean macaque has been studied for its dominance hierarchy, which stays relatively stable over the years, and in aggressive encounters the individual that flees is treated as the loser, even though only about half the time is the one that flees the one that was originally threatened.
