Intertidal, on sand and mud (Ref. 75840). On sandy beaches, in all but the most sheltered areas, often in dense populations. Most common in wave-beaten areas, migrating up and down the beach with the tide. Frequently preyed upon by crabs and birds during migration (Ref. 345). Confined on beaches with coarse, poorly-sorted sediments (Ref. 125508).
Life cycle and mating behavior

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.
