Espinhos dorsais (total) : 7; Raios dorsais (total) : 8; Espinhos anais: 1; Raios anais : 8 - 9. Dark longitudinal lines on body; caudal fin black with light margin dorsally; pectoral base with 1-2 black spots (Ref. 5493).

Biologia     Glossário (p.ex. epibenthic)

Inhabits brackish mangrove estuaries and lower reaches of freshwater streams, usually on mud bottoms (Ref. 44894). Usually found in lagoons and estuaries, particularly where there is vegetation (Ref. 6028, 79840). Occurs frequently in mangrove swamps (Ref. 2847, 79840). Occasionally ascends rivers (Ref. 6028). Feeds mainly on small fishes and crustaceans (Ref. 6028, 79840). Marketed fresh (Ref. 12693).
