Short description

Dorsal spines (total): 0; Dorsal soft rays (total): 10 - 12; Anal spines: 0; Anal soft rays: 12 - 14; Vertebrae: 64 - 67. Distinguished by the pale or colorless pelvic fins, a terminal mouth and the presence of 41 to 48 gill rakers on the 1st gill arch (Ref. 27547). Dorsal fairly high and slightly falcate; pelvic with axillary process (Ref. 27547). Brown to dark greenish above fading to silvery on sides and belly; fins pale (Ref. 27547).

Occurs in brackish waters (20-22 ppt) of coastal lagoons and mouths of rivers and bays (Ref. 4779). Nerito-pelagic (Ref. 58426). Enters rivers in shoals to spawn (Ref. 4779). Feeds on small crustaceans, insects, small fishes (Ref. 28219, 28857), worms and clams (Ref. 58426). No feeding occurs during the upstream migration (Ref. 4779). Collected by fyke nets (Ref. 4526).
