"The lion-tailed macaque (Macaca silenus), or the wanderoo, is an Old World monkey endemic to the Western Ghats of South India." "The hair of the lion-tailed macaque is black. Its outstanding characteristic is the silver-white mane which surrounds the head from the cheeks down to its chin, which gives this monkey its German name Bartaffe - "beard ape". The hairless face is black in colour. With a head-body length of 42 to 61 cm and a weight of 2 to 10 kg, it ranks among the smaller macaques. The tail is medium in length, about 25 cm, and has a black tuft at the end, similar to a lion's tail. The male's tail-tuft is more developed than that of the female."
