Species' maximum length from the Belgian part of the North Sea (Ref. 7882). Found along the coastal zone, often in fine-grained sediments and mud (Ref. 7882). Also found in hard bottom (Ref. 117453). This is a surface deposit feeder (Ref. 96214). Main food based on another species of the same genus; to be replaced with a better reference (Ref. 96292).
