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.
