Minimum depth range from Ref. 114139. Found in soft sediments. Juveniles are preyed upon by sea stars, gastropods, octopus, snapper, and large rays (Ref. 1244). Feeds on phytoplankton (Ref. 114780).
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.
