Udo is famous for their female Haenyo Divers
It's common to see these women dressed in black rubber suits and flippers who make their way down to the sea with nets and fishing baskets slung over their shoulders. Each carrying a hoe, spear and gourd. Without any breathing apparatus, the divers jump into the waters and slowly submerge to great depths in search of shellfish, abalone, seaweed and other marine life. They stay under for three to four minutes at a time, appearing on the surface just to take in a long breath of air before disappearing underwater again.
