The crab-eating macaque (Macaca fascicularis), also known as the long-tailed macaque and referred to as the cynomolgus monkey in laboratories,[1] is a cercopithecine primate native to Southeast Asia. A species of macaque, the crab-eating macaque has a long history alongside humans;[6] it has been alternately seen as an agricultural pest,[7] sacred animal in some temples,[8] and more recently, the subject of medical experiments.[6]
The crab-eating macaque lives in matrilineal social groups of up to eight individuals dominated by females.[9] Male members leave the group when they reach puberty.[10] It is an opportunistic omnivore[11] and has been documented using tools to obtain food in Thailand and Myanmar.[12] The crab-eating macaque is a known invasive species and a threat to biodiversity in several locations, including Hong Kong and western New Guinea.[1] The significant overlap in macaque and human living space has resulted in greater habitat loss,[6] synanthropic living, and inter- and intraspecies conflicts over resources.
