生態學
海洋; 半鹹淡水; 非遷移的; 深度上下限 0 - 32 m (Ref. 96339). 亞熱帶的; 32°N - 4°S, 115°W - 78°W (Ref. 54323)
Eastern Pacific: southwestern coast of Baja California, Mexico and from the Gulf of California to northern Peru (up to the Bay of Sechura). Apparently reaching Los Angeles, USA, but these are perhaps releases from tuna boats.
東太平洋: 墨西哥的下加利福尼亞與從加州灣到祕魯北部的西南方海岸.(向上到塞丘拉灣) 顯然地達到美國洛杉磯，但是這些也許是來自鮪魚船的釋放。
Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm 12.9, range 12 - ? cm
Max length : 22.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 96339); common length : 12.0 cm SL 雄魚/尚未辨別雌雄; (Ref. 9298); 最大年齡: 3 年 (Ref. 905)
背棘 (總數): 0; 臀棘 0; 臀鰭軟條: 17 - 24. Head large and deep. Snout short and pointed, about 2/3 eye diameter; maxilla moderate, tip blunt, just failing to reach lower jaw articulation; lower gill rakers fine and numerous, increasing in large fishes; no gill rakers on posterior face of third epibranchial. Branchiostegal rays 8, long and slender; branchiostegal membrane broad. Silver stripe disappearing at about 8-10 cm SL.
頭部大的且深。 吻短與尖的, 大約 2/3 眼直徑; 顎骨中等的, 頂端鈍的, 正好失敗達到下頜關節; 下鰓耙細且多, 增加較大時魚; 沒有在第三個上鰓骨的後面上的鰓耙。 鰓條骨 8, 長且細的; 鰓蓋薄膜寬的。 銀色的斑紋於大約 810 公分的 SL 消失。
Occurs inshore, principally over mud flats and forming quite large schools. Apparently not making long migrations along sandy or rocky areas. Juveniles feed principally on diatoms, also silico-flagellates, dinoflagellates and small crustaceans; adults also mainly on benthic diatoms. Used as tuna baitfish. Processed into fishmeal and oil.
生活於近海, 主要地在淤泥平台與形成之上相當大群魚群。 顯然地不進行長距離的迴游沿著沙的或岩石區。 稚魚主要吃矽藻，也吃矽鞭毛蟲，腰鞭毛蟲與小型甲殼動物; 成魚也主要吃底棲的矽藻。 當作鮪魚誘餌使用。 加工成魚漿或魚油了。
