In Jeju Island, ?
there is a community of women, some aged in their 80s, which goes diving 10m under the sea to gather shellfish, such as abalone or sea urchins for a living without the help of oxygen masks. With knowledge of the sea and marine life, the Jeju haenyeo (female divers) harvest for up to seven hours a day, 90 days of the year holding their breath for just one minute for every dive and making a unique verbal sound when resurfacing.????
Divers are categorised into three groups according to level of experience: hagun, junggun and sanggun with the sanggun offering guidance to the others.
