Colour: externally dirty light grey, internally whitish or light grey splotched with bluish purple (Ref. 271).
It has a total length of 12 cm. Fisheries: It is heavily exploited due to over exploitation or contaminated by organic pollutants. It is consumed raw, fried, grilled or boiled. Canned industrially (Ref. 271).
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.
