Snub-nosed monkeys are a group of Old World monkeys and make up the entirety of the genus Rhinopithecus. The genus occurs rarely and needs much more research. Some taxonomists group snub-nosed monkeys together with the Pygathrix genus. Snub-nosed monkeys live in Asia, with a range covering southern China (especially Tibet, Sichuan, Yunnan, and Guizhou) as well as the northern parts of Vietnam and Myanmar. These monkeys get their name from the short stump of a nose on their round face, with nostrils arranged forward. They have relatively multicolored and long fur, particularly at the shoulders and backs. They grow to a length of 51 to 83 cm with a tail of 55 to 97 cm.
