Found in many sheltered bays, estuaries, beaches and rocky shores across the region. Shells often seen washed up on beaches close to estuaries such as at Dawlish Warren, Devon; but this species is commonly found on the lowershore stuck to rocks and stones and other large shells. Several may also be found stuck together forming a small stack.
Images were taken at Dawlish Warren Beach, Batten Bay, Plymouth, Devon; and at Spit Point, Par and the River Tamar at Henn Point, Saltash, Cornwall.
