Free and original spider Monkey pictures (Ateles geoffroyi).
Spider monkeys move gracefully through the uppermost layer of the rainforest by means of brachiation, which means swinging hand-over-hand through the branches. Their long arms and flexible shoulder joints are specially adapted for brachiation.
For extra stability, spider monkeys use their gripping tails to hang on to branches as they go. Tails that can grip, like the spider monkey's, are known as prehensile. Spider monkeys can grab, reach, swing from, and hang from their prehensile tails. Their tails are also sensitive to touch, allowing them to pick up small objects such as peanuts.
