The term "haenyeo" refers to female divers from the Jeju Island in South Korea. These skilled women are known for their ability to free dive and collect seafood, such as shellfish and sea urchins, without the use of breathing apparatus. The practice has been passed down through generations and is an important part of the local culture and economy. Haenyeo typically dive in groups and are recognized for their remarkable lung capacity and endurance. They wear traditional wetsuits made from thick fabric to protect against cold water. In 2016, the haenyeo culture was inscribed on the UNESCO Intangible Cultural Heritage list, highlighting its significance.
