Howler Monkeys are a group of primates known for their distinctive loud calls, which can be heard over long distances. They are primarily found in the forests of Central and South America. These monkeys have a unique vocal sac that amplifies their sounds, allowing them to communicate with others in their troop. These monkeys are typically medium to large in size, with long tails that are often prehensile, helping them navigate through the trees. Howler Monkeys are herbivorous, mainly feeding on leaves, fruits, and flowers, and they play an important role in their ecosystem by aiding in seed dispersal.
