South America: interconnected lakes southern to brackish water estuarine area of the rio Tramandai drainage in southern Brazil, from lagoa do Armazem through lagoa do Rincao das Eguas in the south; further in two partially isolated lakes south of the rio Tramandai drainage, namely lagoa do Cipo and lagoa da Solidao.
南美洲: 互相連接對半淡鹹水是南方的湖了在巴西南部的 rio Tramandai 流域的河口區域, 從 lagoa 經過 lagoa 做 Armazem 在南方中做 Rincao das Eguas; 進一步在二部份地隔離了 rio Tramandai 流域湖南方, 即 lagoa 做 Cipo 與 lagoa da Solidao。

背棘 (总数) : 4 - 6; 背的软条 (总数) : 8 - 10; 臀棘: 1; 臀鳍软条: 13 - 18; 脊椎骨: 47 - 49. Scales in lateral line series above lateral band 48-52; predorsal scales 23-26; conical head shape, with a terminal mouth placed near a horizontal line crossing the center of pupil and the middle of head depth and lacks a pronounced angle at the retroarticular joint (Ref. 47314). Differs from O. bicudo by having smaller snout length, larger eye diameter, larger interorbital width and larger head depth (Ref. 47314).
在侧面的条纹 48-52 上面的侧线系列中的鳞片; 前背的鳞片 23-26; 锥形头部形状, 具有一个被放置在 retroarticular 接合横越瞳孔的中心与头部深度的中央并且缺乏一个明显的角的一个水平线的附近的端位口。 (参考文献 47314) 藉由有小的吻长度，较大的眼直径，较大的眼间骨宽度与较大的头部深度有别于 O. bicudo 。 (参考文献 47314)
Occurs almost exclusively in freshwater lakes, but also found occasionally in brackish water lagoons (Ref. 47314).
几乎只生存在淡水湖泊, 也发现偶见于半淡咸水泻湖.(参考文献 47314)
