This group encompasses over 150 primate species, including baboons, macaques, and guenons. Several synonyms can refer to the grivet monkey, including Chlorocebus aethiops. The grivet monkey has a distinctive appearance, with a dark face and grey fur covering the rest of its body. It can be found in countries such as Ethiopia, Sudan, and Kenya.
