生態學
; 淡水; 半鹹淡水 大洋性. 亞熱帶的
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。

簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 4 - 6; 背的軟條 (總數) : 8 - 10; 臀棘: 1; 臀鰭軟條: 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).
在側面的條紋 48-52 上面的側線系列中的鱗片; 前背的鱗片 23-26; 錐形頭部形狀, 具有一個被放置在 retroarticular 接合橫越瞳孔的中心與頭部深度的中央並且缺乏一個明顯的角的一個水平線的附近的端位口。 (參考文獻 47314) 藉由有小的吻長度，較大的眼直徑，較大的眼間骨寬度與較大的頭部深度有別於 O. bicudo 。 (參考文獻 47314)
Occurs almost exclusively in freshwater lakes, but also found occasionally in brackish water lagoons (Ref. 47314).
幾乎只生存在淡水湖泊, 也發現偶見於半淡鹹水潟湖.(參考文獻 47314)
