دريايي; تغييرات عمق 0 - 70 m (Ref. 54915). Subtropical; 30°S - 37°S, 74°W - 70°W (Ref. 54915)
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).
Length at first maturity / Size / Weight / سن
Maturity: Lm 10.5, range 10 - 11 cm
Max length : 28.4 cm SL جنس نر / بدون خواص جنسي; (Ref. 27363)
خارهاي باله پشتي (کل): 0; شعاع نرم باله پشتي (کل): 13-21; خارهاي باله مخرجي 0; شعاع نرم باله مخرجي: 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).
