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).

Các tia vây lưng cứng (tổng cộng) : 0; Các vây lưng mềm (tổng cộng) : 13 - 21; Tia cứng vây hậu môn: 0; Tia mềm vây hậu môn: 12 - 23. Belly not strongly keeled (Ref. 188). Body dark blue dorsally and silvery white ventrally. Fins translucent (Ref. 27363).
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).
