The
Mandrill (
Mandrillus sphinx,) is a
primate of the
Cercopithecidae (Old-world
monkeys) family, closely related to the
baboons and even more closely to the
Drill. Both the Mandrill and the Drill were once classified as baboons in genus
Papio, but recent research has determined that they should be separated into their own
genus,
Mandrillus. The Mandrill is the world's largest species of monkey.
