Ecología
marino pelagic-neritic; rango de profundidad ? - 70 m (Ref. 96339), usually ? - 50 m (Ref. 11035). Tropical; 28°N - 3°S, 112°W - 78°W (Ref. 54686)
Eastern Pacific: Santa Rosalita, Pacific coast of Baja, California, Mexico southward to Punta Sal and Punta Picos, Peru. (Earlier works probably combined data for Opisthonema bulleri and Opisthonema medirastre). Range is extended northwards to San Pedro, California (Ref. 35601). Rare on outer coast of Baja California Sur (Ref. 35601).

Descripción breve
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 0; Radios blandos dorsales (total) : 13 - 21; Espinas anales: 0; Radios blandos anales: 12 - 23. The filamentous last dorsal fin ray distinguishes it from members of any other eastern Pacific clupeoid genus. Separated from eastern Pacific Opisthonema species by having 63 to 110 lower gill rakers in fishes over 14 cm standard length.
Body shape (shape guide): elongated; Cross section: compressed.
Usually occur near the surface of coastal and offshore waters, down to over bottom of continental shelf (Ref. 11035). Form dense schools. Apparently the most abundant of the eastern Pacific species of Opisthonema. Feed on phytoplankton (dinoflagellates and diatoms). Oviparous, with planktonic eggs and larvae (Ref. 35601). Migratory behaviour is undetermined (Ref. 126106). It is reduced to fish meal (Ref. 9291). Oil may be extracted (Ref. 9291). May be canned (Ref. 9291).
