Silvered Leaf Monkeys

Silvered leaf monkeys (Trachypithecus cristatus) live in coastal, mangrove, and riverine forests in Peninsular Malaysia, Sumatra, and Borneo. They are almost exclusively herbivorous. They thrive primarily on leaves; only nine per cent of their diet constitutes fruits, seeds, and flowers. They have a sizeable three-chambered stomach to aid digestion to digest the cellulose found in the hard-to-digest leaves. This digestive system allows for the fermentation of plant matter, much like the stomach of other ruminants like cattle and buffaloes.
