Shell colour variable, specimens may be white, pink, orange. Sculpture is of fine concentric lines (striae). Shell up to 6 cm across.
These shells burrow deep into sand or mud, and in some locations are the dominant species. Their predators include bottom feeding fish such as flounder and whiting. They are deposit feeders.
