背棘 (总数): 6; 背的软条 (总数): 9; 臀棘 1; 臀鳍软条: 18 - 22. Body bluish brown dorsally, silvery ventrally. A broad silvery band with dark blue upper margin running from pectoral fin base to caudal fin base along midbody. Upper surface of head, pectoral and caudal fins blackish (Ref. 27363).

身体蓝色的褐色背面, 银色的腹地。 一条宽的银色条纹用从胸鳍基底到尾鳍基底延续的深蓝色上缘沿着身体中央。 头部的上表皮, 胸鳍与尾鳍鳍黑色的.(参考文献 27363) 在侧面的条纹 52-60 上面的侧线系列中的鳞片; 前背的鳞片 28-35.(参考文献 47314)
Inhabit coastal lagoons and near estuaries, usually in freshwater (Ref. 27363, 59043). Gregarious. Adults feed on zooplankton. Mature adults spawn for the first time at 1-2 years. Eggs are deposited among aquatic vegetation (Ref. 59043). Maximum length estimated from the fact that the congeneric Odontesthes incisa has a common length of 10 cm TL. This species is a cool water predator that has affected the abundance of other species native to the lakes (Ref. 1739). The fisheries has now flourished especially in lakes and reservoirs, in Peru, Argentina, southern Brazil and Chile.
也发现于沿岸浅水区。 (参考文献 27363) 最大的长度估计自同属的 切齿牙汉鱼［Odontesthes incisa］ 有一个 10 公分 TL 的普遍长度的事实了。 这种是原产于湖的已经影响其他种的丰度的一个冷的水掠食者。 (参考文献 1739) 在秘鲁，阿根廷，巴西南部与智利,渔场现在已经在湖与水库活跃尤其。
