Old World Monkeys: Cercopithecidae - Old World Monkeys And People

leaves stomach red pot

Old World monkeys are hunted for food. Some species are used in medical research.


The western red colobus, the proboscis monkey, and the red-shanked douc langur, all considered leaf monkeys, have evolved a four-chamber stomach that brings about a pot-bellied look. The stomach houses bacteria that break down fibrous leaves, the monkeys' main diet. The bacterial action not only releases nutrients from the leaves but also renders harmless the poisons found in some leaves.
