Espinhos dorsais (total) : 9 - 10; Raios dorsais (total) : 8 - 11; Espinhos anais: 3; Raios anais : 7 - 9; Vértebras: 25. Dark gray on back, becoming paler below with overall silvery sheen; lower sides and belly whitish; fins dusky brown to dark brown, darker distally (except pecorals).
An estuary-dependent catadromous fish inhabiting the tidal reaches of rivers, lakes and coastal lagoons where it is found (Ref. 7300, 123463); with salinities less than 1-2 ppt (Ref. 5259). Popular angling species that tends to swim near the bottom in deeper water. Feeds on small fishes, molluscs, worms, shrimps and other crustaceans. During winter (July and August) they move to the mouth of estuaries to breed (Ref. 44894). Individuals are long lived, reaching to more than 40 years (Ref. 123463). Oviparous, egg is pelagic (Ref. 5259) and hatches in 2-3 days. Male reaches maturity at a length of about 22 centimeters; female at about 28 centimeters (Ref. 44894).
