Maturity: Lm ?, range 2 - 3.5 cm Max length : 7.5 cm SHL mâle / non sexé; (Ref. 95344); common length : 6.4 cm SHL mâle / non sexé; (Ref. 78182); âge max. reporté: 16 années (Ref. 104675)
Maximum depth from Ref. 104447. Buries in gravel, sand and mud to more than 10 cm deep along the mid-intertidal zone (Ref. 95344). Preyed upon by naticid gastropods (Ref. 100855). Suspension-feeder (Ref. 78182). In general, suspension feeding bivalves mainly depend on phytoplankton and detritus material for nutrition (Ref. 107088).
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 (Ref. 833). Eggs are discharged through the siphon (Ref. 104667). Spawning: Two periods of high temperature and two spawning peaks may occur in summer due to strong water temperature fluctuations while only one temperature and spawning peak may be expected in a warmer than normal year (Ref. 78182).
