IUCN: Endangered

• Spider monkeys have long limbs and pot bellies.  They have very long legs and tails and are extremely agile.
• Spider monkeys are arboreal (meaning they live in trees), and live up to 35 metres above the ground.
• Spider monkeys have been known to shake a vine occupied by a predator to cause them to fall. They have also been seen breaking off dead branches weighing nearly 5kg and dropping them on predators. 
• They have a prehensile tail, which acts as a fifth limb, able to grasp objects or hold their entire body weight for long periods.
• Acrobatic and swift, spider monkeys move through the trees, with one arm stride covering up to 40 feet (12 metres).
