Howler monkeys are the largest of all New World monkeys and have a lifespan of seven to fifteen years. Habitat: Mantled howler monkeys can be found in the canopies of both lowland and montane rainforests. They are commonly heard long before they are seen searching for leaves in the treetops. A troop of howler monkeys usually consists of eight to twelve females, three or four dominant males and several young.

This monkey is found at elevations of 1,500-3,400 m.t is also widely referred to as the Sichuan snub-nosed monkey. Of the three species of snub-nosed monkeys in China, the golden snub-nosed monkey is the most widely distributed throughout China. Snow occurs frequently within its range and it can withstand colder average temperatures than any other non-human primates.
