Maturity: Lm ? range ? - ? cm
Max length : 35.0 cm TL Männchen/unbestimmt; (Ref. 9626); common length : 25.0 cm TL Männchen/unbestimmt; (Ref. 3702)
Inhabits the surf zone along sandy beaches, but in clear water. Also occurs over muddy bottoms in estuaries and sometimes near coral reef areas. Feeds on small crustaceans washed out of sand by the surf (Ref. 5521). Large specimens are marketed mostly fresh; smaller ones are used as bait.
