The moon snail is a large, round-shelled burrowing sea snail — a predatory marine gastropod of the family Naticidae — prized in East Asian cooking for its big, muscular foot. Pulled from the shell and cooked, the meat is firm, dense and pleasantly chewy with a clean, briny-sweet flavour; it is sliced for sashimi and stir-fry, and in Korea the moon snail (golbaengi) is the star of the spicy cold salad golbaengi-muchim.
