Sulawesi crested macaques are one of seven species of macaque, that are endemic to Sulawesi Island, in Indonesia. They are medium-sized monkeys that are sometimes mistaken as apes, due to the small size of their tail. Their bodies are covered in black, shiny hair, except for their rear ends, which have no fur and are pink in colour.
Sulawesi crested macaques are diurnal primates that like to spend their day foraging on the forest floor. They are very social animals that live in groups consisting of an alpha male, multiple breeding females and their offspring. Grooming is an important behaviour, that occurs between group members, which helps to maintain strong bonds as well as aiding in parasite removal.
