Where seen? This large cockle is sometimes seen on some of our shores, usually alone on sandy areas near seagrasses, coral rubble and reefs.

Features: 5-6cm long. The two-part shell is thick and heavy, oval to rectangular and hemispherical (not flat). There are strong ribs sometimes with beads along the ribs. When submerged, a fringe of short tentacles may emerge from the shell opening.
