The white-faced capuchin monkey, also known as diphtheria capuchin monkey and white-faced capuchin monkey, is a genus of capuchin monkeys of the suborder Apes. * * * There are two subspecies: Nomenclatural subspecies and Gorgona Island subspecies. It is mainly distributed in the neotropical region of Central America, with strong adaptability and extensive habitats, and lives in various wet, dry, primary and secondary forests. Feeding on fruits, nuts, insects, invertebrates and small vertebrates.

The average body length is 43 cm and the tail length is 55 cm. The male weighs 3-4 kg and the female weighs 2-3 kg. The skin on the cheeks is brown, the fur on the top of the head, back and back is pure black, while the fur around the chest, throat, forearm and face is white or yellow-white. It has a curly tail, which is used to grab and carry food and increase posture support. They have a strong sense of territory, and members of the ethnic group will defend their territory from other invaders.

This species is highly social and consists of 15-20 members, and each member will spend a lot of time building social ties and trust in the group. Because of polygamy, male leaders have more mating opportunities and help protect their group members from predators. The female gives birth to a offspring every two years, and the young monkeys are carried, protected and fed by the female. Male young monkeys usually leave the original group at the age of 4 to find a position in the new group.
