Biologi     Ordlista (t.ex. epibenthic)

Found in the intertidal zone on coarse-grained (Ref. 104171) sandy beaches (Refs. 104348, 104171). Some migrate up and down the beach with the tides (Ref. 104348). Actively migrates by jumping out of the sand and riding specific waves (Ref. 104171). Filter-feeder (Ref. 104245). Feeds on phytoplankton, algae, detritus, bacteria and other small suspended particles via its short siphons (Ref. 104246).

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

Semelparous species (Ref. 104352). 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).
