Dorosomatidae (Gizzard shads and sardinellas)
Etymology: Opisthonema: Greek, opisthe = behind + Greek,nema = filament (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Ecología
marino; rango de profundidad 0 - 50 m (Ref. 188). Tropical; 3°N - 4°S, 94°W - 89°W (Ref. 188)
Southeast Pacific: endemic to the Galapagos Islands.
Tamaño / Peso / Age
Maturity: Lm ?  range ? - ? cm
Max length : 26.0 cm SL macho / no sexado; (Ref. 188); common length : 18.0 cm SL macho / no sexado; (Ref. 188)
Espinas dorsales (total): 0; Radios blandos dorsales (total): 13-21; Espinas anales 0; Radios blandos anales: 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).
Forms schools.
