Species' maximum length, and shell height of up to 1.6 cm, from the Belgian part of the North Sea Ref. 7882). Depth based on occurrence (Ref. 2851, p. 719); to be replaced with better reference. Found in fine to muddy substrates, lying directly beneath the surface of the sea floor along the coast. Able to burrow quickly when disturbed (Ref. 7882). It is a sessile-burrower, suspension feeder (Ref. 96498). In general, suspension feeding bivalves mainly depend on phytoplankton and detritus material for nutrition (Ref. 107088).
Life cycle and mating behavior
Γεννητική Ωρίμανση | Αναπαραγωγή | Γεννοβολία | Eggs | Γονιμότητα | Larvae
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.
