Thai Moken Children Can See Underwater Like Dolphins
A tribe off the west coast of Thailand provide an amazing example of the adaptability of the human body. The Moken tribe, a seafaring nomadic tribe, has children that can see underwater twice as well as you can. The underwater eyesight of these "sea-nomads," as they're called, is akin to the sight of a dolphin. Not only can these children see astonishingly clearly underwater, their eyes do not get irritated and red from the salt water like the average person's might. These children have adapted to this lifestyle by diving in the oceans to look for food starting at a young age.
