Length at first maturity / Size / Weight / Age
Maturity: Lm ? range ? - ? cm Max length : 6.4 cm SHL male/unsexed; (Ref. 2758)
Found in shallow (Ref. 105316) sublittoral zone (Refs. 105316, 106644). Inhabits fine well sorted sand (Ref. 2780). Found in areas influenced by estuarine outflows (Ref. 96507). An active suspension feeder (Ref. 96376), and sessile-burrower (Ref. 96498). In general, suspension feeding bivalves mainly depend on phytoplankton and detritus material for nutrition (Ref. 107088).
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.
