Spider Monkeys are found in the tropical jungles of South America, from Southern Mexico to Brazil. The spider monkey is very dexterous and is thought to get it's name from the way it can be seen hanging in the trees. It is often seen with all four hands on separate branches, spread out like a spider's web. The spider monkey can also hang from branches from its strong tail. Their diet mostly consists of fruits and berries and are thought to play a vital part in spreading seeds throughout much of the South American rainforests.
