Animal Name: Blue Monkey.

"The blue monkey or diademed monkey (Cercopithecus mitis) is a species of Old World monkey[3][4] native to Central and East Africa, ranging from the upper Congo River basin east to the East African Rift and south to northern Angola and Zambia. It sometimes includes Sykes', silver, and golden monkeys as subspecies.

Blue monkeys are small (ranging in weight from 4 to 6 kg) and arboreal. The face is nearly naked, usually dark in color (infrequently blue), and has well-developed musculature (Lawlor, 1979). Despite its name, the blue monkey is not noticeably blue; it has little hair on its face, and this does sometimes give a blue appearance, but it never has the vivid blue appearance of a "Mandrill" , for example. It is mainly "Olive (color)"  or grey apart from the face (which is dark with a pale or yellowish patch on the forehead – the "diadem" from which the species derives its common name), the blackish cap, feet, and front legs, and the mantle, which is brown, olive, or grey depending on the subspecies. Typical sizes range from 50 to 65 cm in length, (not including the tail, which is almost as long as the rest of the animal), with females weighing a little over 4 kg and males up to 8 kg.
