背棘 (总数) : 7; 背的软条 (总数) : 8 - 9; 臀棘: 1; 臀鳍软条: 8 - 9. Diagnosis: 53-68 scales in longitudinal series on flanks, plus up to 13 scales on caudal fin base; 17-24 (usually 18 or more) scales in rearward transverse series (Ref. 57413). No discrete dark spot present on upper pectoral fin base, if dark pigment present, not distinct from pigment on nape; sensory papillae on upper rear field of opercle form a forked row (Ref. 81660).
Body shape (shape guide): fusiform / normal.
Occurs in coastal rivers, lagoons, creeks, estuaries (Ref. 6802, 57413, 81660) and mangrove areas (Ref. 6802, 57413). Maximum reported total length 265 mm (Ref. 6802).
