The crab-eating macaque (also referred to as the cynomolgus monkey or the long-tailed macaque) is among the most widespread primate species globally. It belongs to the group of Old World Monkeys.

Crab-eating macaques have ten subspecies native to Southeast Asia, including the Nicobar long-tailed macaques, the dark crowned long-tailed macaques, and the long-tailed macaques. Each subspecies has a slightly different diet, habitat, and physical appearance.

The greatest threat for crab-eating macaques’ survival in the wild is loss of habitat. However, they currently have a large and stable population.
