The Necklace Shell has a  buff to pale yellow shell with a spiral row of brownish marks near its upper edge. Similar to Alder’s Necklace Shell which is smaller and darker. Shell height up to 3cm.

It is found buried in the lower shore, in sheltered to moderately exposed sand. It feeds on small bivalves by drilling a round hole through its shell. Common and widespread along all British coasts.
