Épines dorsales (Total) : 11; Rayons mous dorsaux (Total) : 19 - 22; Épines anales: 2; Rayons mous anaux: 5 - 7. Silvery grey to very dark, young with 4 or 5 black vertical bars on sides, disappearing with growth; pelvic and anal fins usually dark. Chin with 5 pores and 10 to 13 pairs of small barbels along median edges of lower jaws and subopercles, increasing in length posteriorly. Gas bladder with numerous lateral appendages interconnected in a complicated pattern in adult. Sagitta semicircular and moderately thin (Ref 51721).
Body shape (shape guide): fusiform / normal.
Found usually over sand and sandy mud bottoms in coastal waters, especially in areas with large river runoffs (Ref. 7251), in magrove areas (Ref. 138854). Juveniles often enter estuaries. Feeds mainly on crustaceans, mollusks and fishes (Ref. 7251)..
