Könsmognad: Lm ?, range 1 - ? cm Max length : 3.7 cm SHL hane/ej könsbestämd; (Ref. 130712); rapporterad maxålder: 3.00 år (Ref. 104267)
Found in the intertidal zone to a depth of 1.5 m (Ref. 104267). Lives slightly buried in muddy sands of shallow water environments, particularly in mangrove lagoons (Ref. 81903). Adults prefer to settle in areas with fine or coarse sand where conditions are harsher during low tide (Ref. 104267). Strictly a filter-feeder (Ref. 104242). Suspension feeder (Ref. 105167). In general, suspension feeding bivalves mainly depend on phytoplankton and detritus material for nutrition (Ref. 107088). Sensitive to salinity variations but resistant to hypoxic conditions (Ref. 104267). Associated with a crab (Refs. 104147, 105309), bivalve and polychaetes (Ref.105309).

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 (Ref. 833).
