Banded wedge shells have a typical serrated edge and are reasonably long. The outer layer of the shell of living organisms, the periostracum, is made up of a brownish-green parchment-like material. This layer usually disappears quickly after death. Hundreds of living and dead banded wedge shells can wash ashore after a frost or an off-shore wind. Live banded wedge shells can also be found after sand nourishments. In southern Europe, banded wedge shells are sold as a delicacy at the market and food stores.
