ORANGUTAN

　　Everything orangutans need is in the trees. Their favorite food is fruit, especially figs, and they seem to know what fruit is ripe in what part of the forest at what time. They will occasionally eat insects or small mammals, but tend to be herbivores most of the time. They get their water from where rainfall collects on leaves and in the holes of trees. Orangutans even sleep in the trees. They build a new platform nest from leaves and branches each night and sleep 40 to 60 feet off of the ground!
