Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 12 - 15; Dorsal soft rays (total): 9 - 11; Anal spines: 3; Anal soft rays: 7 - 9. This species is distinguished from its congeners, except G. labiatus, by having a thick, extremely well developed lips, with the lower lip deeply notched medially; differs from labiatus by the presence of a dark band extending posteroventrally from the dorsal-fin origin (vs. absent), and by the dorsal, anal and caudal-fin color patterns, where fins are partially or completely covered with well-defined circular dots (vs. small longitudinal stripes) (Ref. 118066).

This species is found exclusively in stone bottom habitats, covered with all sizes of stones and rocks along the rio Quaraí and its tributaries (Ref. 118066).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01862 (0.00849 - 0.04084), b=3.01 (2.83 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.5 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 (10 of 100).
