A Moken child launches himself from a jetty into the blue-green waters of the Andaman Sea. The Moken ‘sea gypsies’ are a semi-nomadic people who live in the Mergui Archipelago.

It is thought that Moken children learn to swim before they can walk; a recent study also found that the eyesight of Moken children is 50% more powerful than that of European children, possibly due to generations of underwater fishing.
