Naturalists have discovered that orangutans can not only swim but that they also know how to fish. The orangutans in Borneo were previously thought to be non swimmers but they have learnt how to swim across the river to get to the best fruits. They have also learnt how to use a tree branch as a spear in order to catch a fish after watching fishermen using rods. However, they have also worked out that it is less work to steal fish from unattended fishing lines rather than going to the effort of catching the fish themselves. At this rate they will quickly be overtaking some of the lesser intelligent human individuals among us.
