Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 13 - 17; Spine anali: 0; Raggi anali molli: 16 - 19; Vertebre: 67 - 74. Caudal fin emarginate (Ref. 9279). Branchiostegal rays: 11-12 (Ref. 36575).
Body shape (shape guide): elongated.
Common in coastal and lagoon areas with mangroves (Ref. 9279). Also found in bays and harbors (Ref. 36575). Penetrate fresh water (Ref. 9279). Adults occur in small schools. Feed mainly on small fishes (Ref. 9279). Oviparous, with neustonic larvae (Ref. 36575). Eggs are attached to vegetation and floating objects via long filaments (Ref. 36575). Usually caught with the help of artificial lights (Ref. 9279). Marketed fresh (Ref. 9279).
