Scientific Details

This large and diverse family is notable for shells with elegant shapes and beautiful colour patterns in radial rays, more frequently found among tropical species. Shells are from small to medium size, elongate to ovate or rotund in outline, may be rostrate or flexed posteriorly, vary from fragile to thick and solid, exterior smooth or with some sculpture, periostracum thin. Hinge narrow, two cardinals in each valve, laterals may or may not be present, ligament external. Adductor muscles more or less equal, pallial sinus deep. They are deposit feeders, with the gill surface area reduced and the labial palps enlarged.
