cockle Corculum cardissa Family Cardiidae updated Aug 10 Where seen? This intriguing clam is sometimes seen on our Southern shores, on sandy areas near coral rubble and seagrasses. Elsewhere, often found on sandy bottoms often associated with reefs, sometimes in dense colonies. Features: 4-6cm. The two-part shell is heart-shaped with the opening of the valves down the centre of the 'heart'. One half of the valve is flat while the other is convex. The colour may be dull yellowish to sometimes with bright flecks of red and yellow. The clam attaches itself to the ground with small byssus threads. Human uses: It is collected for shell craft. |
