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.

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 4 - 6; Dorsal soft rays (total): 8 - 10; Anal spines: 1; Anal soft rays: 13 - 18; Vertebrae: 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).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00537 (0.00239 - 0.01205), b=3.06 (2.87 - 3.25), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.6 ±0.3 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (15 of 100).
