A marine bivalve mollusc with a smooth wedge-shaped, cream to pale brown shell (sometimes slightly yellow or green and with pinky-purple bands) containing dark (often bluey-purple) meat. They are found all around the Australian coast and are hand-harvested from the intertidal zone of sandy beaches with good surf (from about 10cm below the surface), mainly south from the NSW/Queensland border to the beginning of the Great Australian Bight in SA.
