Turbo cornutus, common name the horned turban, is a species of sea snail, marine gastropod mollusk in the family Turbinidae. Turbo cornutus is enjoyed as a delicacy in Japan, where it is known as "sazae." After cooking, the corkscrew-like animal can then be drawn out of its shell using its hard operculum, or hard, rocky lid, to which it is firmly attached. The operculum is not edible, and must be discarded along with the animal's shell after eating. Since sazae is such a prized delicacy in Japan, and thus commercially important, natural populations are supplemented by artificially reared juveniles. Large numbers of animals are bred and then dumped into the open sea to complete their growth. See "Turbo cornutus". Wikipedia. Retrieved 2014-12-16.
