Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 7; Raggi dorsali molli (totale) : 8; Spine anali: 1; Raggi anali molli: 8 - 9. Dark longitudinal lines on body; caudal fin black with light margin dorsally; pectoral base with 1-2 black spots (Ref. 5493).

Biologia     Glossario (es. 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).
