The mandrill[1] (Mandrillus sphinx) is a primate of the Old-World monkey family (Cercopithecidae). It is among the two species in the Mandrillus genus and drill.
- The mandrills reach a height of around 80 cm. The species features a large head, a compact body with long, powerful limbs, and an erect stubby tail.
- The wide range of rotation of the clavicles allows for quadrupedal walking, tree climbing, and arm function.
- The opposable thumbs allow these monkeys to grasp tree branches. Both sexes have paired mammary glands in the chest region.
- The coat is olive green with lighter underparts. It has a bright blue to bare purple rump.
- A mandrill’s face has a red stripe down the center of the snout and around the nostrils, while the sides of the snout are striped lengthwise and blue in color.
- Mandrills have patches of red fur over their eyes and a yellow beard. These colorations are duller in females and juveniles than in adult males.
