Orangutans are more swingers than they are jumpers. But it sure is impressive to see them swing from one tree to another, using the relative strength of each branch to their advantage. Of course, it helps when even their feet are really like two more hands. Here a young orangutan swings upside down through Tanjung Puting National Park in Indonesian Borneo.
