Cercopithecus is a genus of primates commonly known as guenons, which are native to Africa. These monkeys are characterized by their long tails, colorful fur, and expressive faces. They typically inhabit forests and savannas, where they live in social groups and are known for their agility and playful behavior. There are several species within the Cercopithecus genus, including the Vervet monkey and the Green monkey. Guenons primarily feed on fruits, leaves, and insects. Their vocalizations and social structures are complex, making them an interesting subject of study in primatology and animal behavior.
