Descripción breve
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 0; Espinas anales: 0; Radios blandos anales: 43 - 48. Belly with around 26 scutes. Lower jaw not strongly projecting; hind tip of maxilla meets lower bulge of maxilla blade and is overlapped by it; teeth very small or minute. Dorsal fin well behind midpoint of body; anal fin long, its origin before dorsal fin origin. A silver band along flank.
Body shape (shape guide): fusiform / normal; Cross section: compressed.
Occurs in coastal waters and off river mouths (e.g. Río Mayo, Gulf of California) thus perhaps tolerating lowered salinities. Feeds on planktonic crustaceans. Spawns over an extended period off Costa Rica.
