Old World Monkeys
Cercopithecidae
The Versatile Primates of Africa and Asia: Old World Monkeys (Cercopithecidae) are a diverse group of primates found across Africa and parts of Asia. They inhabit a wide range of environments, from dense rainforests and savannas to mountainous regions and urban areas. Unlike New World Monkeys, they lack prehensile tails and have narrow, downward-facing nostrils. There are about 150 species of Old World Monkeys, including well-known species like the Olive Baboon (Papio anubis), Vervet Monkey (Chlorocebus pygerythrus), and Rhesus Macaque (Macaca mulatta). Their body sizes vary greatly, from the small Talapoin (Miopithecus spp.) at around 30 cm (12 in) long to the large Mandrill (Mandrillus sphinx), one of the world’s heaviest monkeys. Most Old World Monkeys are social animals, living in complex groups with strict hierarchies. Their social structures often involve dominant males and tight female kin groups. They are highly vocal, using a variety of calls, facial expressions, and body language to communicate. Diet varies widely within the family, from folivorous colobus monkeys specializing in leaves to omnivorous macaques and baboons that eat fruits, seeds, insects, and even small animals. Many species are ground-dwelling, while others are agile tree-climbers. Old World Monkeys are incredibly adaptable, allowing some species to thrive near humans. However, they still face threats from habitat loss, hunting, and conflict with people. Conservation efforts focus on protecting forests and reducing human-wildlife conflict to ensure the future of these fascinating primates.
