Cercopithecinae is a subfamily of primates that includes various species commonly known as Old World monkeys. This group is characterized by their non-prehensile tails, which are typically shorter than those of New World monkeys. They are primarily found in Africa and Asia and are known for their social structures, often living in large troops. Members of the Cercopithecinae subfamily include well-known species such as baboons, macaques, and mangabeys. These monkeys are generally omnivorous, feeding on fruits, leaves, seeds, and small animals. Their adaptability to different habitats has allowed them to thrive in diverse environments, from forests to savannas.
