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.
Tamaño / Peso / Age
Maturity: Lm ? range ? - ? cm
Max length : 20.3 cm SL macho / no sexado; (Ref. 116661)
Espinas dorsales (total) : 4 - 6; Radios blandos dorsales (total) : 8 - 10; Espinas anales: 1; Radios blandos anales: 13 - 18; Vértebra: 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).
Occurs almost exclusively in freshwater lakes, but also found occasionally in brackish water lagoons (Ref. 47314).
