Similarly, are monkeys meat eaters?
The diets of nearly all monkeys and apes (except the leaf-eaters) are composed of fruits, nuts, leaves, insects, and sometimes the odd snack of a bird or a lizard (see more about chimpanzees). Most primates have the capacity for eating sugary fruit, the capacity for eating leaves and the capacity for eating meat.
Accordingly, are monkeys vegan?
Wild howler monkeys have been caught on camera raiding chicken coops and eating bird's eggs. The behaviour has surprised researchers as howler monkeys are thought to be exclusively vegetarian. The egg-eating behaviour has evolved among black and gold howlers living in forest in Rio Grande do Sul in Brazil.
In primates, canines function as both defense weapons and visual threat devices. Interestingly, the primates with the largest canines (gorillas and gelada baboons) both have basically vegetarian diets.
