Các tia vây lưng cứng (tổng cộng) : 0; Tia cứng vây hậu môn: 0; Tia mềm vây hậu môn: 26 - 29. Snout moderate, pointed, tip at or just above eye center; maxilla moderate, tip pointed and reaching onto pre-operculum (but not beyond), extending beyond second supra-maxilla; sub-operculum with a distinct triangular projection on hind margin; lower gill rakers fine and slender, increasing in larger fishes. Silver stripe along flank ,probably disappearing in larger fishes.
Occurs inshore along sandy beaches and in tide streams, forming large schools. Juveniles to about 7 cm occur on beaches and in bays, thereafter moving further from the shore. Feeds by filtering phytoplankton and zooplankton.
Spawn in school (Ref. 205).
