Biology The unclosed side is turned up when burrowed into the substrate, mostly sand or muddy sand, in which it forms a hole. Goes up and down into the substrate with a respectable speed (disappears into sand within 15 seconds). [details]

Distribution A recent immigrant from America, this species is now very common along the European coasts. First discovered on German North Sea Coasts in 1979, it had reached NE Denmark and the Dutch Wadden Sea by 1982, and NE France by 1991. [details]

Habitat In sand or muddy sand. [details]

Morphology Whitish-grey mollusc with brown drawings. Length six times as wide, slightly curved, and can attain at least 20 cm long. Both tips equally wide.With many growing bands and a scaly surface. As with all Ensis spp. one side is never completely closed. [details]
