Overview
The common whelk has a solid, teardrop-shaped shell sculpted with spiral ridges and curved ribs. Its colour and surface vary considerably: cream or yellowish shells may show reddish markings, and the tan outer coating can be thin or worn away. Its oval opening ends in a short siphonal canal.
This marine snail lives mainly below the tideline on muddy sand, gravel and rock in the North Atlantic. It eats worms and bivalves, taking live prey as well as carrion. Clusters of egg capsules attach to submerged surfaces; empty masses washed onto beaches are sometimes mistaken for sponges.
