生態學
海洋; 深度上下限 0 - 50 m (Ref. 188). 亞熱帶的; 33°S - 42°S, 64°W - 52°W (Ref. 188)
Southwest Atlantic: southern Brazil (estuary of the Lagoa dos Patos) and Uruguay to at least Bahía Blanca, Argentina; some of the more southerly records (even to the Beagle Channel) must refer to Sprattus fuegensis.
西南大西洋: 巴西 (Lagoa dos Patos 的河口) 南部與烏拉圭到至少阿根廷的布蘭卡港; 一些比較向南記錄 (甚至到小獵犬峽道) 指的一定是 Sprattus fuegensis 。
大小 / 重量 / 年齡
Maturity: Lm ? range ? - ? cm
Max length : 9.0 cm SL 雄魚/尚未辨別雌雄; (Ref. 188); common length : 7.5 cm SL 雄魚/尚未辨別雌雄; (Ref. 188)
背棘 (總數): 0; 背的軟條 (總數): 18-19; 臀棘 0; 臀鰭軟條: 12 - 23. Belly sharply keeled. Flanks silvery without a distinct silver stripe (cf. Platanichthys). Distinguished from R. melanostoma of freshwaters by having more dorsal and pectoral fin rays and total gill rakers; from small Sardinella and Harengula by the evenly rounded hind margin of the gill opening; and from Sprattus fuegensis by having i 6 pelvic fin rays.
腹面銳利地龍骨。 側面銀色的沒有明顯的銀色斑紋 (比較 Platanichthys). 與淡水的 R. melanostoma 藉著具有區分了更背部的與胸鰭鰭條與總鰓耙; 從小的 沙丁魚 與 Harengula 藉由均勻地圓的鰓裂的後緣; 而且從 Sprattus fuegensis 藉著具有 i 6個腹鰭鰭條。
Forms schools in coastal waters, apparently inshore but not entering freshwater.
在沿岸水域中形成魚群, 顯然近海但是不進入淡水。
