Interesting Spider Monkey Facts. 1. Their Name Spider monkeys are seen hanging onto separate branches of the trees using all of their four limbs and the tail as well, thus giving them a spider like appearance. This is why these monkeys are called spider monkeys. 2. Have a Tail as a Fifth Hand Spider monkeys have a prehensile tail which helps them to move from branch to branch. Muscular and tactile, this tail is used by the monkey as a fifth hand to hang from the branches, which leaves their hands free for food collection.
