Most monkeys live in warm jungles. The snub-nosed monkey is different - it lives at altitudes of 1,500 to 3,400 metres, where in winter there is deep snow. Its thick golden coat keeps it warm even when it is below freezing.
Their face is one of the most colourful in the animal world. Babies have especially blue faces. Scientists think the bright colour helps mums and aunts spot their babies from far away in the dense forest.
The little upturned nose is probably an adaptation to the cold. In freezing weather a long pointed nose could get frostbite. A short snub nose is safer.
They live in large family groups - sometimes more than 100 monkeys together. They eat leaves, fruit, seeds, and even lichen (the green-grey fluff that grows on tree bark in cold forests). When food is hard to find in winter, the group huddles together to keep warm.
