Max length : 53.8 cm TL 雄鱼/尚未辨别雌雄; (Ref. 126428); common length : 30.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 5476); 最大体重: 2.8 kg (Ref. 126428)
背棘 (总数) : 14; 背的软条 (总数) : 16; 臀棘: 3; 臀鳍软条: 7. Diagnosis: body oblong, rather deep; dorsal profile strongly convex at level of dorsal-fin origin (Ref. 57395). Snout at least as long as eye diameter (Ref. 57395), eyes large (Ref. 81655). Mouth oblique (Ref. 57395), small (Ref. 81655) with very thick (Ref. 57395) and fleshy (Ref. 81655) lips. Chin with 6 pores (erroneously reported as 4 since original species description; Ref. 81655), but without median pit (Ref. 57395). Dorsal fin long; second anal fin spine longest and stoutest; ctenoid scales covering body and head (except snout) and interradial membranes of soft parts of dorsal and anal fins (Ref. 57395). Caudal fin rounded (Ref. 57395, 81655).
Coloration: uniformly brown, more or less dark; young individuals often with lighter spots on flanks (Ref. 57395, 81655). In small specimens (< 60 mm SL), distal part of soft dorsal fin, posterior 3/4 of caudal fin and distal part of anal fin transparent (Ref. 81655).
Body shape (shape guide): fusiform / normal; Cross section: compressed.
Relatively rare species (Ref. 57395). Inhabits coastal waters (Ref. 3660, 57395), estuaries and coastal lagoons (Ref. 2683). Juveniles and sub-adults often in estuaries and lagoons (Ref. 2135, 57395, 81655), in freshwater (Ref. 2135), where sexual maturation begins (Ref. 57395).
栖息于沿岸水域 (参考文献 3660) ,河口与岸边泻湖。 (参考文献 2683) 常见于河口与泻湖中的稚鱼与亚成鱼, 在淡水中.(参考文献 2135)
