In Japan and Korea, rappan’s meat is considered a delicacy. Its main economic importance in other areas is as a predator in the economically significant local mussels. Black Sea Mytilus galloprovincialis is the main target in the Black Sea, while the Adriatic Sea also attacks the imported species of Tapes philippinarum and Anadara inaequivalvis. In Chesapeake Bay, the oysters and the local snails are the victims.
