Where seen? This elegantly ribbed whelk is usually busy foraging at low tide among seaweeds or on the sand near seagrasses, especially at night. Commonly seen on many of our shores.

Features: 2-2.5cm. Shell narrower, beige to white with with dark markings (bluish or brown). The shell has a neat pattern of fine, narrow raised bumps and ridges. The foot has a pair of 'tails' at the ends and the operculum has tiny 'teeth' along the edges.
