Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 1; Dorsal soft rays (total): 7; Anal spines: 1; Anal soft rays: 5. Dorsal series of plates reduced, with no plates in the dorsal series between the dorsal-fin origin and the end of the adipose fin; both teeth cusps approximately equal in size (Ref. 42856).

Found in a small, shallow stream, with clear water and moderate to strong current. Bottom formed by rocks, loose stones and gravel. Forest and grass usually present on the margins (Ref. 45132).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00537 (0.00203 - 0.01424), b=3.13 (2.90 - 3.36), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
