Maturity: Lm 54.7, range 48 - ? cm
Max length : 122 cm FL macho / no sexado; (Ref. 40637); common length : 94.0 cm FL macho / no sexado; (Ref. 3277); peso máximo publicado: 36.0 kg (Ref. 5217); edad máxima reportada: 23 años (Ref. 42149)
Espinas dorsales (total): 6 - 7; Radios blandos dorsales (total): 18-21; Espinas anales 2-3; Radios blandos anales: 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).
