JEJU ISLAND - Driving loud motorcycles, the “haenyeo” on the southern scenic island of Jeju arrived at the sea to begin their work at 10:30 a.m. on a Saturday morning. Donning black-and-orange diving suits and flippers, the female divers swiftly grabbed their “tewak” - orange ball-like flotation devices - and descended to the depths of the sea to catch various aquatic organisms ranging from abalone to conch.
