Descrição breve
Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 0; Raios dorsais moles (total) : 13 - 21; Espinhos anais: 0; Raios anais moles: 15 - 17. The filamentous last dorsal fin ray distinguishes this species from members of any other eastern Pacific clupeoid genus. Lower gill rakers 50 to 87 in fishes over 14 cm standard length (intermediate between O. medirastre with 41 to 69 and O. libertate with 63 to 110, but neither of these occur in the Galapagos Islands).
Body shape (shape guide): fusiform / normal; Cross section: compressed.
Forms schools.
