Because of their long skinny limbs, they look like spiders when hanging by their tails.

Spider monkeys have very flexible shoulder joints that enable them to swing easily from branch to branch. Their prehensile tail, used as a fifth limb, is muscular and can support the whole weight of the animal. The fleshy part of the tail even has its own fingerprints.
