Moor Macaques are mostly black-brown, with dark faces and very short tail. However, there are some individuals with grey fur, and interestingly, there is almost always an individual with mostly whitish fur within the group. Females show genital swelling during fertile periods, and newborns show clear/nude skin before turning dark.

Nicknamed "The Kingdom of Butterflies", the Bantimurung-Bulusaraung National Park (ca. 43,750 ha) is known as the second-largest karst area in the world and ​contains one of the oldest known cave paintings. The National Park also includes the Karaengta Forest where a group of habituated Moor Macaques can be found. The group was habituated during the 1980s by Japanese researchers, and it has been studied since then by different research projects.
