//**​As you walk in, you choose to walk through a cave or beneath a waterfall, and you emerge onto a walkway where you have a bird's eye view of the South American exhibit. Note how the different animals utilize different parts of the same habitat -- some in the treetops, some on the floor, etc. By using the same area in different ways, more species can survive in the same space. **// //**Looking into the trees, you can see black handed spider monkeys as they brachiate (swing) from branch to branch. They use their tails as rudders as they jump. Click here to learn more about spider monkeys. **////****//Black handed spider monkey//****// ======

//**Along the walkway, you'll see a branched area close to the railing. This is where the marmosets are housed. Because of their small size, they need to be kept close to visitors in order to be seen. Three types of marmosets are kept at the zoo: cotton top marmosets, golden lion tamarins, and callimicos. They alternate the time they spend on the exhibit with their time spent in off exhibit enclosures. Cotton top tamarins and golden lion tamarins eat mostly insects. They live in small family groups and share taking care of the babies. Even the fathers pitch in.

//**Closely related are the callimicos. They are also marmosets but are a little behind in their evolution. One of the main differences between them and the other marmosets is that they have three molars instead of just two. Molars are used to grind tough vegetation. Cotton top marmosets and golden lion marmosets are better equipped to eat a diet made of insects. Callimicos still carry the extra molars from the days when vegetation made up a larger part of their diet. Click here to learn more about callimicos. **////* *Callimico**// ======
