Southeast Pacific: Coquimbo, Valparaiso and south to Talcahuano, Chile; perhaps reaches further south to Mocha Island, but more southerly records may refer to Sprattus fuegensis. Subspecies have been noted (Ref. 6698): Strangomera bentincki bentincki (Talcahuano southward) and Strangomera bentincki cuga (Valparaiso to Talcahuano).

Occurs in schools at or near the surface in coastal waters. Feeds on plankton, especially diatoms (filter-feeding). Breeds mainly from June to November, from a length of about 10 cm. Eggs and larvae are planktonic (Ref. 52017). Mainly used for fishmeal.
Apparently releases planktonic eggs (similar to the demersal eggs of northern hemisphere Clupea).
