Environment: milieu / climate zone / depth range / distribution range
生态学
海洋; 深度上下限 0 - 50 m (Ref. 188). 亞熱帶的; 36°N - 6°S, 123°W - 77°W (Ref. 188)
Eastern Pacific: Los Angeles, California to Sechura Bay, Peru. (Included in at least some accounts of Opisthonema bulleri and especially Opisthonema libertate which used to be the only Pacific species recognized).
東太平洋: 加州的洛杉磯到祕魯的塞丘拉灣。 (包括在至少中了 Opisthonema bulleri 的一些描述與尤其過去是的 Opisthonema libertate 唯一的太平洋的種辨認出).
大小 / 重量 / 年龄
Maturity: Lm ? range ? - ? cm
Max length : 30.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 55763); common length : 20.0 cm SL 雄鱼/尚未辨别雌雄; (Ref. 9291)
背棘 (总数): 0; 背的软条 (总数): 13-21; 臀棘 0; 臀鳍软条: 12 - 23. Body moderately deep and compressed; posterior edge of gill openings with two clearly visible, fleshy, protuberances; gill rakers numerous, 41 to 69 on ceratobranchial (in fish longer than 14 cm total length); last dorsal ray elongated and filamentous; back gray-green with silver-white flanks and a black spot behind the gill slit followed by a yellow lateral strip (Ref. 55763). The filamentous last dorsal fin ray distinguishes it from members of any other eastern Pacific clupeoid genus. Separated from other eastern Pacific Opisthonema by having 41 to 69 lower gill rakers in fishes over 14 cm standard length.
身体中等纵深而扁长形的; 鳃裂的后缘有两个清楚看得见﹐肉质的, 突起; 鳃耙很多的, 41 到 69 在角鳃骨上;(在鱼长度超过 14 公分全长中) 持续被延长而且丝状的背鳍鳍条; 背面灰色-绿色的有在鳃缝后面的银白色的侧面与一个黑色的斑点跟随着黄色的侧面长条了.(参考文献 55763) 丝状的最后背鳍鳍条区别它和任何其他的东太平洋的鲱鱼属的成员。 与其他的东太平洋 Opisthonema 在超过 14 公分标准长度的鱼中借着具有 41 到 69个下鳃耙分开。
Usually found near shore, forming schools. Feeds on crustaceans and pteropods.
通常发现于被形成群体的海岸附近。 吃甲壳动物与翼足目的软件动物。
