Short description Chiavi di identificazione | Morfologia | Morfometria

Spine anali: 3; Raggi anali molli: 7. Silvery with about seven faint pinkish bars on side on body; pelvic fins yellow (Ref. 13442).

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).
