Mandrilinae

Mandrilinae is a subfamily of Old World monkeys found in Africa. This subfamily includes the mandrill, the drill, and the putty-nosed monkey. These monkeys are characterized by their large size, colorful faces, and short tails. They are primarily arboreal, meaning they live in trees, and are found in the tropical rainforests of West and Central Africa.

Mandrills are the largest of all monkeys, with males being significantly larger and more vibrantly colored than females. Their faces are distinguished by prominent red and blue stripes, and their bodies are covered in dark fur. Drills are similar in appearance to mandrills but are generally darker in color and lack the bright facial markings. Putty-nosed monkeys are smaller and have a distinctive white patch on their nose, which gives them their name.

These monkeys are diurnal, meaning they are active during the day, and live in social groups. Their diet consists mainly of fruits, but they also consume insects, leaves, and roots. They play an important role in their ecosystem as seed dispersers.

Mandrills and drills are classified as endangered due to habitat loss and hunting. Conservation efforts are underway to protect their populations and habitats. The putty-nosed monkey is currently listed as least concern, though habitat fragmentation remains a threat.
