Crab-eating macaque Facts
Crab-eating macaque, also known as cynomolgus monkey, belongs to the group of Old World Monkeys. There are 10 subspecies of crab-eating macaque that are native to Southeast Asia. They inhabit subtropical and tropical forests, coastal lowland forests, deciduous and evergreen forests, mangroves and swamps. The greatest threat for the survival of crab-eating macaques in the wild is habitat loss. Also, crab-eating macaques are often collected from the wild for the purpose of medical researches and due to pet trade. Despite these factors, population of crab-eating macaques is large and stable in the wild.
