Längd vid första mognad / Storlek / Vikt / Ålder
Könsmognad: Lm 54.7, range 48 - ? cm
Max length : 122 cm FL hane/ej könsbestämd; (Ref. 40637); common length : 94.0 cm FL hane/ej könsbestämd; (Ref. 3277); publicerad maxvikt: 36.0 kg (Ref. 5217); rapporterad maxålder: 23 år (Ref. 42149)
Taggstrålar i ryggfenan (totalt) : 6 - 7; Mjukstrålar i ryggfenan (totalt) : 18 - 21; Taggstrålar i analfenan: 2 - 3; Mjukstrålar i analfenan: 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).
Body shape (shape guide): short and / or deep.
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).
