Description
Size: Maximum shell length 7.5 cm, commonly to 5 cm.

Max. weight reported: 210 gm

Color: Outside of shell dull white under the straw-colored periostracum. Interior is whitish.

Shell moderately thin and rounded in outline, very inflated, globose. Anterodorsal margin is sub-horizontal, strongly rounded anteriorly. Posterodorsal margin slightly convex and sloping posteriorly. Umbones are well in front of midline of valves. Lunule is flattish, moderately large, slightly depressed near the umbones, nearly symmetrical. Outer surface of valves is dense, with irregular concentric growth lines. Periostracum is thin and appressed to shell surface. Ligament sunken, set in an oblique groove of posterodorsal margin. They have a somewhat elongate adductor muscle, part of which is separate from the pallial line. The hinge is essentially toothless in the adult. They harbor sulphur-oxidising bacteria in their gills from which they derive most of their nutrition.
