Indo-Pacific: Kuwait to Fiji, north to southern Japan, south to New Caledonia. Reported from Samoa (Ref. 9710), Tonga (Ref. 53797), and the Society Islands (Ref. 2847).
Inhabit harbors, natural embayments, brackish estuaries and the lower reaches of freshwater streams, frequently occurring among mangroves. Feed on worms, crustaceans, insects and plant matter (Ref. 7020, 44894, 48637). The dorsal, anal and pelvic spines are believed by Philippine fishers to be venomous and capable of inflicting wounds (Ref. 6565). Used in Chinese medicine (Ref. 12166). In Hong Kong live fish markets (Ref. 27253). Marketed as fresh (Ref. 12693).
Multiple spawner (Ref. 102820).
