Vervet monkeys are gregarious animals living in organised troops which are dominated by males. Their access to food resources is regulated by the hierarchy of dominance. Females stay with their natal group, whereas males leave the group when they reach puberty. The diet of the vervet monkey is omnivorous, feeding on fruits, flowers and leaves as well as insects. It can differentiate between green and ripe fruit, as primates are one of few mammals with colour vision.
