Deep burrowing species (Ref. 93290). Found in coastal waters (Ref. 1051996), from low intertidal (Ref. 122429) to depths of 55 m (Ref. 105196, 122429). Found buried in shallow subtidal soft bottoms, specifically in coarse sandy sediments or silty sands at depths of 2 to 50 (Ref. 105111). Also found in fine sand (Ref. 93290).
Life cycle and mating behavior
परिपक्व अवधि | पुनरुत्पत्ति | मछलीऔ का अंडे देना | 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.
