Short description

Dorsal spines (total): 0; Dorsal soft rays (total): 13-21; Anal spines: 0; Anal soft rays: 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.

Biology     Glossary (e.g. epibenthic)

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). It is reduced to fish meal (Ref. 9291). Oil may be extracted (Ref. 9291). May be canned (Ref. 9291).

IUCN Red List Status (Ref. 115185)
