The Northern woolly spider monkey, also known as Brachyteles hypoxanthus, is a primate species found in the tropical forests of northern South America, particularly in Brazil and Colombia. This monkey is characterized by its long limbs, prehensile tail, and thick, woolly fur, which helps it adapt to its arboreal lifestyle. These monkeys are social animals, often living in small groups. They primarily feed on fruits, leaves, and flowers, playing a crucial role in their ecosystem as seed dispersers. Unfortunately, the Northern woolly spider monkey is classified as endangered due to habitat loss and hunting.
