The body length of the mangabey is 50-60 cm; the tail length, 75-95 cm. The extremities are long. There are large cheek pouches. The color of the hair ranges from gray to black. Some species have a tuft on the head. The mangabeys are distributed in Central and West Africa. They inhabit forests and are mainly arboreal, living in bands of as many as 20-40. They are very mobile and agile. Mangabeys are often kept in zoos, where they reproduce readily.
