Mandrillus Sphinx
Mandrill
Tropical rainforests
The Mandrill, Mandrillus sphinx, is a large and colorful primate, recognized as one of the most striking of all monkeys. Adult males are particularly notable for their vibrant blue and red facial coloration and a yellow beard, standing out against their primarily olive green or dark grey fur. They boast an impressive size, with males significantly larger than females, weighing up to 35 kg (77 lbs) and measuring about 81 cm (32 inches) in length, not including their short tails. The females are less colorful and smaller, weighing up to 15 kg (33 lbs). Mandrills have strong, muscular bodies, adapted for both terrestrial and arboreal life in the rainforests of Central Africa.

| Generation Length: | 7-8 years |
| Average Weight: | Males: 19-37 kg, Females: 10-15 kg |
| Average Length: | Males: 75-95 cm, Females: 55-66 cm |
| Lifespan: | 20-30 years in the wild, longer in captivity |

| Conservation Status: | Vulnerable (VU) |
Mandrills are highly social animals, forming large groups known as hordes, which can number in the hundreds, making them the largest social units of any primate species except humans. Within these groups, Mandrills exhibit complex social structures and behaviors, including grooming and play, which reinforce social bonds and hierarchies. They are primarily diurnal, spending their days foraging on the forest floor and resting in trees at night.
Their diet is omnivorous, consisting mainly of fruits, seeds, and vegetation, supplemented by invertebrates, small vertebrates, and eggs. This varied diet allows Mandrills to play a crucial role in their ecosystem as seed dispersers, contributing to the health and diversity of their rainforest habitats.
Reproduction in Mandrills is influenced by the dominance hierarchy, with the most colorful and dominant males having access to breeding females. Females give birth to a single offspring after a gestation period of about six months. Infant Mandrills are cared for primarily by their mothers but may also receive attention from other females in the group.
The population of the Mandrill is currently classified as Vulnerable by the IUCN, facing threats from habitat destruction and hunting for bushmeat. Their survival is dependent on the conservation of their rainforest habitat and the implementation of measures to reduce hunting pressures. Conservation efforts focus on protected area management, law enforcement to combat poaching, and community engagement in conservation strategies.

Fun Fact
Mandrills are known for their vibrant facial colors and are the largest monkey species.
Their colorful faces become even more intense when excited, making them unique among primates. Mandrills use their bright coloration to communicate with others, especially for social mating signals. They are native to the rainforests of Central Africa and spend most of their time on the ground foraging for fruits, seeds, and insects.
