Épines dorsales (Total) : 0; Rayons mous dorsaux (Total) : 13 - 16; Épines anales: 0; Rayons mous anaux: 25 - 35; Vertèbres: 39 - 40. This species is distinguished by the following characters: short maxilla, its posterior tip not reaching to posterior margin of the opercle; first supramaxilla elongated, longer than half length of second; abdomen is covered with 5-8 + 9-10 = 14-17 keeled scutes; scutes anterior to pectoral fin absent; 1UGR (upper gill rakers of first gill arch) 15-18, 1LGR (lower gill rakers of first gill arch) 20-23, 1TGR (total gill rakers of first gill arch) 36-40; 2UGR 12-15, 2LGR 20-23, 2TGR 33-38; 3UGR 10-13, 3LGR 12-14, 3TGR 23-27; 4UGR 9-11, 4LGR 9-12, 4TGR 18-22; no distinct black blotches on the dorsal fin; caudal peduncle is rather deep, 10.1-11.5% (mean 10.5%) of SL, and short 8.7-10.4% (usually shorter than 10%; mean 9.3%) of SL; pre-dorsal-fin is short, 48.0-50.4% of SL; snout is short, 3.9-4.8% of SL; body elongate, 23.0-26.9% (rarely 21.2%; mean 24.5%) of SL (Ref. 129422).
Body shape (shape guide): elongated; Cross section: compressed.
Marine, pelagic and presumably schooling (Ref. 189). Found mostly inshore in bays, lagoons, harbours, mangrove pools and estuaries, thus apparently able to tolerate lowered salinities (Ref. 189, 30573). It contributes to general clupeoid catches, but no special fishery (Ref. 189). Used as a baitfish in Pacific Ocean (Ref. 189).
