Biologi     Ordlista (t.ex. epibenthic)

Common shell length is between 5 to 7 cm (Ref. 101426). Subtidal, living just below the surface of sandy substrates. Also found intertidally in mud and gravel (Ref. 116664). Has high lethal temperature threshold, surviving El Niño events (Ref. 105334). In general, suspension feeding bivalves mainly depend on phytoplankton and detritus material for nutrition (Ref. 107088).

Life cycle and mating behavior Könsmognad | Reproduktion | Lek | Eggs | Fecundity | 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.
