Arunachal macaque It is the first species of macaque to have been discovered since 1903, when the Indonesian Pagai Island macaque was discovered. This monkey was reported on the basis of a good quality photograph as the holotype. In 2011, some researchers suggested, on the basis of morphological variation within the Assamese macaque, that it might be better treated as a subspecies. Subsequently, it was also discovered in Bhutan, where it was observed and photographed in the Trashi Yangshi area in 2006. The Arunachal macaque is compactly built and has a very dark face. It lives at high altitudes, between 2000 m
Nicobar long-tailed macaque territory measures some on average. The Nicobar long-tailed macaque is a frugivore, with its principal diet consisting of fruits and nuts. In common with other crab-eating macaques it turns to other sources of food—typically in the dry and early rainy tropical seasons—when the preferred fruits are unavailable. This alternate diet includes young leaves, insects, flowers, seeds, and bark; it is also known to eat small crabs, frogs and other creatures taken from the shorelines and mangroves when foraging in these environments. Macaque populations which live in areas close to human settlements and farms frequently raid the croplands for food, and
