Benthic; brackish; depth range 0 - 300 m (Ref. 356). Tropical, preferred 28°C (Ref. 107945); 26°N - 5°N, 64°E - 94°E

Length at first maturity / Size / Weight / Age
Maturity: Lm ? range ? - ? cm Max length : 20.9 cm SHL male/unsexed; (Ref. 96220); max. reported age: 4 years (Ref. 8702)
Mainly inhabits brackish waters, wherein it occurs as thick beds in estuaries, backwaters, ports and harbors (Ref. 7693). Found in areas with somewhat reduced salinity within intertidal and shallow subtidal waters (Ref. 348). Though sporadic, it is also found on corals, rocks, hard objects or growing in bunches, on various soft bottoms to a depth of about 4 m (Refs. 101354, 53, 348 ). Feeds on diatoms, zooplankton and detritus (Ref. 107090). Also in Ref. 115735.
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.
