Max length : 41.0 cm TL mannelijk / geslacht onbekend; (Ref. 7251); common length : 30.0 cm TL mannelijk / geslacht onbekend; (Ref. 6077); max. gepubliceerd gewicht: 530.00 g (Ref. 40637)
Anale stekels: 3; Anale zachte stralen: 7. Silvery with about seven faint pinkish bars on side on body; pelvic fins yellow (Ref. 13442).
Body shape (shape guide): fusiform / normal.
Inhabits shallow coastal waters in open sandy and surf areas, seagrass beds, near reefs, and mangrove channels (Ref. 7251). Enters brackish water, sometimes even fresh water (Ref. 3722). May occur in small aggregations (Ref. 3722). Feeds on benthic invertebrates such as worms, clams, crustaceans (Ref. 3722); also feeds on insects (Ref. 9303). Often seen feeding in sand patches among reefs by thrusting its mouth into the sediment and expelling sand from the gill openings (Ref. 13442). Easily approached (Ref. 9710). Marketed fresh but not highly esteemed; also processed into fishmeal (Ref. 3722).
