Sea gypsies and land sickness

The Bajau Laut of South-East Asia, also known as “sea gypsies” live in house boats or stilt houses built on top of coral reefs and when they do spend the occasional night on solid ground they often experience ‘land sickness’.

The best Bajau free-divers can dive to depths of over 20 metres and stay there for several minutes in the search for fish. Studies have shown that “sea gypsy” children from Thailand and Burma have unusually good underwater-vision because their eyes have adapted to the liquid environment.
