Maturity: Lm 54.7, range 48 - ? cm
Max length : 122 cm FL 雄鱼/尚未辨别雌雄; (Ref. 40637); common length : 94.0 cm FL 雄鱼/尚未辨别雌雄; (Ref. 3277); 最大体重: 36.0 kg (Ref. 5217); 最大年龄: 23 年 (Ref. 42149)
背棘 (总数): 6 - 7; 背的软条 (总数): 18-21; 臀棘 2-3; 臀鳍软条: 16 - 18. Dorsal and anal fins have very long, dark anterior lobes (Ref. 26938). No scutes; a broad patch of orange-yellow on abdomen in front of anal fin; pectoral fins blackish (Ref. 13442).
Adults frequently in channels or holes, over sandy flats, around reefs, and at times over mud bottoms; usually solitary or in small schools; smaller fish tolerate brackish water. Spawn offshore (Ref. 26938). During the summer, juveniles are found in large schools especially in the surf zone along sandy beaches. Adults feed on mollusks, crabs, shrimps, and small fishes; juveniles on benthic invertebrates. Excellent food fish (Ref. 9626). Highly esteemed game fish caught on light tackle (Ref. 26938).
