Mandrill, the largest monkey primate in the world. The head is large and long. There is a bone protrusion on both sides of the nasal bone, on which there are longitudinally arranged ridge protrusions, which are grooves, covered with green skin, and bright red between the ridges. There are about 6 main grooves on each side of the male, and the red part extends around the nasal bone and snout. This colorful special pattern looks like a ghost, so it is called mandrill.
