Environment: milieu / climate zone / depth range / distribution range
Ecology
Benthic; depth range 0 - 100 m (Ref. 348), usually 0 - 20 m (Ref. 75831). Tropical; 25°N - 21°S, 44°E - 149°E
Indo-West Pacific: from Gulf of Aden to Taiwan, south to Queensland, Australia.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm Max length : 18.0 cm SHL male/unsexed; (Ref. 348); common length : 10.0 cm SHL male/unsexed; (Ref. 348)
Actively collected and often over fished, or commercially cultured for the shells which are used in large quantities for shellcraft. Transparent shells are locally used in some areas as a substitute for window glass in houses. Soft parts are consumed by coastal populations (Ref. 348). Found in sandy or muddy substrates in shallow estuarine lagoons, coves and small bays where salinity of water ranges from 10-35 ppm (Refs. 80041, 128042). Also found on seagrass (Ref. 122159). On mangrove swamps and shrimp ponds (Ref. 75840).
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.
