The gray-cheeked mangabey[1] (Lophocebus albigena), also called the white-cheeked mangabey, is an Old World monkey found in the forests of central Africa.
- The gray-cheeked mangabey is a sizeable arboreal primate with gray and often whitish cheeks.
- Their long, lanky bodies are dark or black gray. L.a. albigena, a nominate subspecies, typically has a black spot on the nape and withers (the area between the shoulder blades).
- The hair on their head is scruffy and long, resembling small horns above their eyebrows.
- Their face, eyes, and skin are also dark. In addition, their chest and front legs are heavier than the rest of the body.
- The long gray or brown hairs on the shoulders and neck form a cape. They have long tails and long limbs that give them balance when running through the forest.
- Their tail is somewhat prehensile and powerful enough to grab onto branches while leaping through trees.
