Langurs are also known as leaf monkeys due to their vegetarian diet. They also have large and complex stomachs to help them digest cellulose.
Head and body length: Female: 46-51cm, Male: 50-58cm. Tail length: Female: 67-75cm, Male: 67-75cm. Weight: Female 5.7kg, Male: 6.6kg.
These langurs have a silvered appearance, due to the grey tips to their dark brown-black fur. The groin and the underside of the tail are yellowish. Infants are born orange but develop grey fur after three months.
Silvered langurs range from Burma and Indochina to Borneo.
They inhabit coastal, mangrove and riverine forest, and plantations.
The majority of the silvered langur's diet is made up of leaves, but they also feed on fruit and shoots.
Silvered langurs live in groups of 15-28, usually with one male and numerous females. Males defend their troops from other groups and are vigilant against predators. Infants are looked after by all females in the troop. They are arboreal and diurnal and move quadrupedally through the forest.
Little is known about the silvered langur's reproductive biology.
