Dorosomatidae (Gizzard shads and sardinellas)
Etymology: Opisthonema: Greek, opisthe = behind + Greek,nema = filament (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Ökologie
seewasser; tiefenbereich 0 - 50 m (Ref. 188). Tropical; 3°N - 4°S, 94°W - 89°W (Ref. 188)
Southeast Pacific: endemic to the Galapagos Islands.
Size / Gewicht / Alter
Maturity: Lm ?  range ? - ? cm
Max length : 26.0 cm SL Männchen/unbestimmt; (Ref. 188); common length : 18.0 cm SL Männchen/unbestimmt; (Ref. 188)
Rückenflossenstacheln (insgesamt): 0; Rückenflossenweichstrahlen (insgesamt): 13-21; Afterflossenstacheln 0; Afterflossenweichstrahlen: 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.

Estimates based on models
Preferred temperature (Ref.
123201): 14.5 - 23.7, mean 19.3 °C (based on 4 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00912 (0.00433 - 0.01920), b=3.04 (2.87 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.3 ±0.4 se; based on size and trophs of closest relatives
Widerstandsfähigkeit (Ref.
