Cercopithecoidei

Cercopithecoidei is a superfamily of Old World monkeys. This group encompasses a diverse array of primates found throughout Africa and Asia. They are characterized by their generally medium to large size, with most species exhibiting tails that are not prehensile. Their dentition is typically adapted for a mixed diet, often including fruits, leaves, seeds, and insects. Cercopithecoids are diurnal and arboreal or terrestrial, depending on the species.

This superfamily is divided into two families: Cercopithecidae and Colobidae. The family Cercopithecidae, often referred to as guenons, macaques, and baboons, is the larger and more diverse of the two. Members of this family are found in a wide range of habitats, from rainforests to savannas. They are known for their complex social structures and varied behavioral patterns.

The family Colobidae, comprising colobus monkeys, langurs, and proboscis monkeys, is primarily arboreal and largely folivorous, meaning they feed mainly on leaves. Their digestive systems are adapted to process tough plant matter, often featuring sacculated stomachs. Colobids are generally found in forests and woodlands across Africa and Asia. Both families within Cercopithecoidei play significant ecological roles in their respective environments.
