African Green Monkey

Chlorocebus aethiops

The name African green monkey is used in different ways, and Chlorocebus aethiops is commonly treated as the grivet, one of the green monkeys of northeastern Africa. It occurs in countries such as Ethiopia, Eritrea, Sudan, and Djibouti, especially in savanna woodland, riverine forest, scrub, and areas near farms or villages. The coat is grey to olive with a pale underside, a dark face framed by lighter cheek hair, and a long tail. Like other Chlorocebus monkeys, grivets live in social troops with strong visual signals, alarm calls, and opportunistic feeding on fruit, seeds, leaves, insects, and human crops.

These monkeys are not suitable household pets and are usually encountered through zoos, primate research colonies, sanctuaries, or conflict-management programs. Professional care requires social housing, climbing space, foraging opportunities, and strict barriers between monkeys and visitors or staff because bites and zoonotic disease risks are real. In biomedical settings, African green monkeys have contributed to virology and immunology research, but taxonomy and colony origin should be recorded carefully because several Chlorocebus species are involved under similar common names. Conservation concerns are often local rather than range-wide, involving habitat loss, trapping, road mortality, and crop-raiding retaliation.
