背棘 (總數) : 11; 背的軟條 (總數) : 11; 臀棘: 3; 臀鰭軟條: 8 - 9. This species is distinguished from its congeners by the following set of characters: 3.5 scale rows between fifth dorsal-fin spine base and lateral line; ventral edge of first two infraorbitals above rear end of maxilla straight in fish less than ca 30 cm SL, but a moderate concavity of the ventral edge of the first two infraorbitals above the posterior part of upper jaw obvious in specimens about 35 cm SL; front edge of dorsal scaly area on head slightly curved (convex) without small scales; total gill rakers 15-19, modally 17; deeper body, 45-48% SL (mean 47% SL); A III, 8-9, usually III, 8; smaller orbit diameter, 2.9-4.9 (mean 3.7) in head length/orbit diameter; second anal-fin spine (2AS) clearly longer than third anal-fin spine (3AS), 2AS/3AS 1.2-1.56 (mean 1.4); scales on preopercle flange absent; pelvic and anal fins uniformly dark black (Ref. 86288).
Body shape (shape guide): fusiform / normal; Cross section: compressed.
Body shape (shape guide): fusiform / normal; Cross section: compressed.
Mainly in brackish waters of estuaries and inlets, coastal rivers and tidal creeks, occasionally entering lower sections of freshwater streams (Ref. 44894). Juveniles inhabit protected bays and estuaries (Ref. 47715). Usually occurs singly or small groups, but may migrate in schools (Ref. 48635).
