Duri punggung (Keseluruhan (total)) : 0; Duri dubur: 0; Sirip dubur lunak: 19 - 23. Body moderately elongate, but somewhat compressed. Snout fairly short, about 3/4 eye diameter; maxilla long, tip sharply pointed, reaching almost to edge of gill cover; gill cover canals of walkeri-type. Anal fin moderate, its origin under or a little before midpoint of dorsal fin base. A narrow silver stripe along flank.
Pelagic (Ref. 96339). A schooling species occurring in coastal waters, most often in muddy estuaries in fully salt, brackish or apparently freshwater, penetrating only a few kilometers up rivers. Maturing females were caught in January, August and October in the Gulf of Nicoya, Costa Rica, suggesting a protracted spawning season. The eggs are oval. TL = 1.219 SL.
Spawn in school (Ref. 205).
