Colobus monkeys are a group of primates found primarily in the forests of Africa. They are known for their striking black and white fur, long tails, and unique thumb structure, which is reduced or absent. These monkeys are herbivorous, primarily feeding on leaves, fruits, and flowers, and they have specialized stomachs to help digest their fibrous diet. Colobus monkeys are social animals, living in groups called troops, which can consist of several individuals. They are agile climbers, spending most of their time in trees, where they use their long limbs and tails for balance. Their vocalizations, including grunts and hoots, help maintain communication within the troop.
