Treeshrews have the largest brain for their body size in the world and rarely make a mistake. They also have the most demanding metabolism. They need food every two hours, even if it means leaving the safety of the treetops to find it. There's no one else around and she has the fruit all to herself. For now. Darkness brings a change to the forest. Only the toughest creatures venture out with their very effective weapons. Thousands of vicious quills on a porcupine's back means he'll be left to eat in peace. At night, the best place for a treeshrew is safe up in the nest. Until now, the forest has provided well. But she's yet to learn how fickle the rainforest can be. Morning, and like every treeshrew, she wakes up hungry. Someone's up before her. And they're heading right for the great tree. Orangutans are 500 times her size. They are fruit-eating machines and can strip a tree bare in no time. They're not the only ones attracted to fruit-bearing trees. The hungry will come from far and wide. If she's going to get her breakfast, she'd better hurry. Forest giants have got their first.
