Our brain is amazingly adaptable. For the Moken children, this adaptation comes naturally because of the environment in which they live. The Moken tribe is made up of about 3000 people and they live on the islands in the Andaman Sea, off the west coast of Thailand. They are nomadic (meaning that they move around a lot, never staying in one place for too long). This video shows us how these Moken kids have "super" vision underwater. They are able to see underwater twice as well as a normal person because they have learned a "trick" of how to adapt their vision, by closing their pupils as far as humanly possible. In fact, scientists have discovered that any child can learn this trick.
