The mona monkey is a species of Old World monkey found in West Africa, known for its distinctive appearance with a black face, white whiskers, and a long tail. They have a varied diet that includes fruits, seeds, insects, and small animals. Mona monkeys are arboreal and live in the tropical rainforests and wooded areas of West Africa, often forming social groups with complex social structures.
