The rainforest supports a wide variety of animals with many adaptations that enable them to survive in their habitat, including the long beak of the toucan. This adaptation allows the bird to reach fruit from the limbs of trees that cannot support its weight. Other adaptations of rainforest animals camouflage them.
The slow moving sloth is well adapted for life in the rainforest. Its slow movement makes it difficult for predators to spot it as it moves through the trees feeding. Most of the time, it hangs upside down from tree branches. The moisture of the rainforest keeps the sloth's fur slightly damp, allowing blue-green algae to grow, coloring the sloth to match the forest canopy.
Spider monkeys use their long tail to wrap around tree branches as another limb, which allows them to maintain balance as they gather fruits, seeds and nuts to eat. They spend most of their time in the upper branches of trees. Often they grasp the tree branch with all four limbs and the tail when resting, giving them the appearance of a spider.
Poison arrow frogs are about the size of a human thumbnail and carry enough poison in their skin to kill about 100 people. Their brightly colored skin is a part of their adaptation to live in the rainforest. The bright colors warn other animals to leave them alone.
