Crab-eating macaque crab-eating macaque is a known invasive species and a threat to biodiversity in several locations, including Hong Kong and western New Guinea. The significant overlap in macaque and human living space has resulted in greater habitat loss, synanthropic living, and inter- and intraspecies conflicts over resources. "Macaca" comes from the Portuguese word "macaco", which was derived from "makaku", a Fiot (West African language) word ("kaku" means monkey in Fiot). The specific epithet "fascicularis" is Latin for a small band or stripe. Sir Thomas Raffles, who gave the animal its scientific name in 1821, did not specify what he meant by
Rhesus macaque Jean-Baptiste Audebert, who applied the name to the species, stated: "it has no meaning". According to Zimmermann’s first description of 1780, the rhesus macaque is distributed in eastern Afghanistan, Bangladesh, Bhutan, as far east as the Brahmaputra Valley in peninsular India, Nepal, and northern Pakistan. Today, this is known as the Indian rhesus macaque "M. m. mulatta", which includes the morphologically similar "M. rhesus villosus", described by True in 1894, from Kashmir, and "M. m. mcmahoni", described by Pocock in 1932 from Kootai, Pakistan. Several Chinese subspecies of rhesus macaques were described between 1867 and 1917. The molecular differences identified
