Environment: milieu / climate zone / depth range / distribution range
生态学
海洋; 深度上下限 0 - 50 m (Ref. 188). 熱帶; 25°N - 5°S, 109°W - 77°W (Ref. 188)

大小 / 重量 / 年龄
Maturity: Lm ? range ? - ? cm
Max length : 20.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 55763); common length : 18.0 cm SL 雄鱼/尚未辨别雌雄; (Ref. 188)
背棘 (总数) : 0; 背的软条 (总数) : 13 - 21; 臀棘: 0; 臀鳍软条: 12 - 23. The filamentous last dorsal fin rays distinguish it from any other eastern Pacific genus. Separated from other eastern Pacific Opisthonema by having only 25 to 36 lower gill rakers in fishes over 14 cm standard length.
丝状的最后背鳍鳍条区别它和任何其他的东太平洋的属。 藉由在超过 14 公分标准长度的鱼中只有 25 到 36个下鳃耙与其他东太平洋 Opisthonema 分开了。
Forms schools. Apparently the least abundant of the eastern Pacific species of Opisthonema. Feeds on crustaceans and pteropods. Caught along with the other species of the genera.
形成鱼群。 显然最不丰富的 Opisthonema 的东太平洋种. 吃甲壳动物与翼足目的软件动物。 捕捉以及属的另一个种。
