Depth based on occurrence (Ref. 2758, p. 805); to be replaced with better reference. Minimum depth from Ref. 2703. Species' maximum length from the Belgian part of the North Sea (Ref. 7882). Found along the coasts and further out into the open sea, mainly on top of sea banks. Shallowly burrows in coarse-grained sediment. A suspension feeder (Ref. 7882).
Members of the class Bivalvia are mostly gonochoric, some are protandric hermaphrodites. Life cycle: Embryos develop into free-swimming trocophore larvae, succeeded by the bivalve veliger, resembling a miniature clam.
