Assumed total length is 2.5 cm (Ref. 344). Maximum depth from Ref. 104365. Found on beach and shoreline (Ref. 104365). Infaunal in shallow sand, usually in environments rich in particulate organic matter (Ref. 344).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | 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.
