背面の脊椎 (合計) : 0; 背鰭 (合計) : 13 - 21; 肛門の骨: 0; 臀鰭: 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).
