Grey langurs

Grey langurs are a genus of Old World monkeys once thought to be a single species. Seven distinct species are now recognised, which are widespread throughout south Asia. The most northerly species are generally larger and heavier than the southern langurs and walk with their tails pointing forward, while southern langurs point their tails backwards. Grey langurs, with their black hands and face, are also known as Hanuman langurs after the monkey-god, and so are considered sacred in the Hindu religion.
