Woolly spider monkeys, also known as Brachyteles, are large primates native to the tropical forests of Central and South America. They are characterized by their long limbs, prehensile tails, and thick, woolly fur. These monkeys are social animals, often found in groups, and they primarily feed on fruits, leaves, and flowers. These monkeys are known for their vocalizations, which include a variety of calls used for communication within their groups. Unfortunately, woolly spider monkeys are considered endangered due to habitat loss and hunting. Conservation efforts are underway to protect their populations and preserve their natural habitats.
