We carry wholesale Spotted Tun shells, Tonna dolium, also called tonna tessellate, tonna sulcosa, or banded tun shells and tonna cepa, giant tun seashells from 1 inch up to 8 inches in size. Spottted tun shells and banded tun shells are from the family Tonnidae. These shells are light weight and are great shells for hermit crabs. Spotted tun shells are also used in making seashell ornaments, shell characters, candles and in shellcraft and shell art. The giant tun shells are larger and roomier and are perfect for making beach wedding centerpieces.  Tun shells are thinner and usually roomier than helmet shells. They are almost exclusively tropical, prefer deeper water, and feed mainly on fish, seaurchins and crustaceans. Their free-swimming larval life is lengthy and has helped some species to spread great distances
