The mandrill, a primate native to the tropical rainforests of Central Africa, is known for its strikingly colorful face and rump. Found across countries like Gabon, Cameroon, and Equatorial Guinea, mandrills belong to the Old World monkey family. They hold the distinction of being the largest monkey species in the world. Their substantial size and distinct features make them a notable presence in their dense forest habitats.
Key Measurements of a Mandrill
Adult mandrills exhibit significant physical dimensions. A typical adult male mandrill weighs between 70 to 119 pounds (32 to 54 kilograms), with some individuals reaching up to 120 pounds. Their body length, measured from head to rump, usually ranges from 28 to 37 inches (70 to 95 centimeters). Females are considerably smaller, averaging around 27 pounds (12 kilograms).
Male mandrills typically stand about 32 inches (81 centimeters) tall at the shoulder when on all fours. Females, by comparison, have a shoulder height of approximately 22 inches (56 centimeters). Both sexes possess a short, stubby tail, generally measuring between 2 to 4 inches (5 to 10 centimeters) in length.
Size Differences Between Males and Females
Mandrills display one of the most pronounced examples of sexual dimorphism among all primates. Males are substantially larger and heavier than females, often weighing two to three times as much.
For instance, while a male might average 70 to 119 pounds, a female typically weighs around 27 pounds. A male’s head and body length can be up to 37 inches, whereas a female’s is closer to 22-28 inches. This difference extends to height, with males standing taller at the shoulder. Males also exhibit more vibrant facial and rump coloration compared to the more subdued hues of females.
Mandrill Size in Perspective
Its classification as the largest living monkey species is based on its significant weight and robust build. While often associated with baboons due to their similar appearance, mandrills belong to their own distinct genus, Mandrillus. Their closest relative, the drill, is considered the second-largest monkey.
Some baboon species, such as the chacma baboon, can achieve considerable lengths. However, the mandrill generally surpasses other monkey species in terms of overall mass and bulk.
