It is found in muddy, sandy and fine gravel shores, from the middle to lower shore. Utilising a muscular foot, it burrows up to 5cm into the sand, and when covered by water they open their shells and extend a pair of short siphons to filter-feed on zooplankton. It can live up to 10 years, and is fished commercially and prayed upon by wading birds. It is common and widespread.
