Spider monkeys are species of primate. Native to the jungles of South America, the primates are so named because of their long, prehensile tails which help them grip branches and lanky arms. Their nimble hands also lack thumbs. The monkeys live in groups of up to three-dozen animals which split into smaller groups for feeding and sleeping. The females typically give birth to one baby every two to five years and after ten weeks the young start to become independent. Spider monkeys appear in Kong: The Animated Series.
