Pectoral filaments 4; fin membranes vivid yellow in life, except in large specimens, > ca 35 cm SL. Vomer with deciduous tooth plates on both sides, except in juveniles. Posterior part of maxilla deep, 3-4% of SL. Short tooth plate extension onto lateral surface of lower jaw. 7-9% SL (Ref. 41639).
Biology : Occur mainly over shallow muddy bottoms in coastal waters. Also enter rivers (Ref. 3479, 11230). Juveniles found in estuaries. During winter, adults ascend the rivers. They usually form loose schools, although larger fish are more often observed in pairs or singly (Ref. 6390). Feed on prawns and fish (largely members of Mugilidae, Engraulidae, and Sciaenidae) with occasional polychaetes. Frequency of crustaceans to fish in the diet varies seasonally. Larvae (7-30 mm TL) feed mainly on copepods and mysids but also take shrimps and prawn larvae (Ref. 57343). Juveniles (31-60 TL) feed on prawns shrimps and mysids (Ref. 57343).
