Description synthétique
Clés d'identification | Morphologie | Morphométrie
Épines dorsales (Total) : 0; Épines anales: 0; Rayons mous anaux: 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.
Body shape (shape guide): elongated; Cross section: compressed.
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.
