The Heck’s Macaque[1] (Macaca hecki) is a macaque native to Sulawesi, Indonesia. This Old-World monkey is diurnal.
- Heck’s macaques are rarely observed or photographed, so it isn’t easy to describe their appearance. However, they do look quite similar to black-crested macaques.
- They both have tiny, almond-shaped brown eyes, silky black fur, and small vestigial tail tips, leading some to misidentify these Old-World Monkeys as great apes.
- However, there are still some significant differences, primarily the spiny black crest on a black-crested macaque’s head, which the Heck’s macaque lacks.
- Heck’s macaques have a broad, prominent forehead and narrow faces with sunken cheeks.
