A holobenthic type that crawls out from a cocoon fixed on the substrate and burrows immediately, usually associated with intertidal populations in North Sea region and adjacent waters and a pelagic larvae associated with subtidal populations (Kruse et al., 2003; Kruse et al., 2004). In Isle of Sylt, North Sea, egg cocoons found on intertidal flats between Feb-April (Kruse et al., 2004). Spawning varies with location. In North Sea, main spawn March, secondary (pelagic) spawn from offshore in Oct (Kruse et al., 2004). At Whitstable, spawned four times in one year, main late Feb-April (Gibbs, 1968). 600-1920 / m² Oosterschelde (Coosen et al., 1994), 800 / m² at Whitstable (Gibbs, 1968).
