deskripsi pendek
Kunci identifiaksi (pengenalan) | Morfologi | Morfometrik
Duri punggung (Keseluruhan (total)) : 0; Duri dubur: 0; Sirip dubur lunak: 15 - 19. Body rather elongate, but somewhat compressed. Snout moderate, about 3/4 eye diameter; maxilla moderate, tip narrowly pointed, reaching onto sub-operculum, but not to edge of gill cover; gill cover canals of panamensis-type. Anal fin short, its origin below posterior third of dorsal fin base. A narrow silver stripe along flank, deeper above anal fin (about 3/4 to 2/3 eye diameter).
Body shape (shape guide): elongated; Cross section: oval.
A schooling species occurring in coastal waters. Pelagic. Frequently caught over sand or gravel in the Gulf of Nicoya, Costa Rica, but also over mud.
May spawn throughout the year in the Gulf of Nicoya, Costa Rica (Ref. 189). Spawn in school (Ref. 205).
