Body shape (shape guide): elongated.
Occurs in shallow and generally turbid coastal water over muddy bottoms, often around river estuaries. Schooling species (Ref. 6949). Occasionally enters estuaries and brackish waters (Ref. 57401). Feeds on mainly on fishes belonging to the Engraulidae, Clupeidae, Lutjanidae and Synodontidae families and also on squid from the Loliginidae family (Ref. 9626). Maximum reported size: 71cm (Ref. 57401). Marketed fresh and salted.
