Chacma Baboon Physical Description from Wikipedia
The chacma baboon (Papio ursinus), also known as the Cape baboon, is, like all other baboons, from the Old World monkey family. It is one of the largest of all monkeys.
Physical description
Chacma baboon is perhaps the longest species of monkey, with a male body length of 50 to 115 cm (20 to 45 in) and tail length of 45 to 84 cm (18 to 33 in). It also one of the heaviest; the male weighs from 21 to 45 kg (46 to 99 lb). Baboons are sexually dimorphic, and females are considerably smaller than males. The female chacma weighs from 12 to 25 kg (26 to 55 lb). It is similar in size to the olive baboon and of similar weight to the more compact mandrill, which is usually crowned the largest of all monkeys. The chacma baboon is generally dark brown to gray in color, with a patch of rough hair on the nape of its neck. Unlike the males of northern baboon species (the Guinea, hamadryas, and olive baboons), chacma males do not have a mane. Perhaps the most distinctive feature of this baboon is its long, downward-sloping face. The canine teeth of male chacma baboons have a mean length of 3.86 +/- 0.30 cm at the time they emigrate from their natal troop. This is the time of greatest tooth length as the teeth tend to wear or be broken thereafter.
The three subspecies are differentiated by size and color. The Cape chacma is a large, heavy, dark-brown, and has black feet. The gray-footed chacma is slightly smaller than the Cape chacma, lighter in color and build, and has gray feet. The Ruacana chacma generally appears to be a smaller, less darkly colored version of the Cape chacma.
