The tufted grey langur is a large, lanky monkey with a black face, a tuft of light grey hair on a small head, and grey-brown body fur that is paler toward the middle. The long tail is held upright in an S-shaped loop. Head and body length is 55–80 cm, with a tail of 75–90 cm, and adults weigh 11–20 kg, males more than females. The Indian animals are somewhat larger than those of Sri Lanka (Wikipedia, general species account; New England Primate Conservancy).
The species is found in south-east India and Sri Lanka. It is mainly a leaf-eater, taking leaves, twigs and fruit, with flowers and insects as well, and groups typically have one adult male. A female usually bears a single young, or rarely twins, after about six months of gestation. Tigers, dhole, grey wolves, mugger crocodiles and Indian rock pythons occasionally take young and sub-adult langurs (Wikipedia, general species account).
