Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 8; Anal soft rays: 11. Head and body below lateral midline whitish with many small dark grey spots (versus dark reddish brown); one black and white whitish longitudinal stripe of about same width (width of black stripe 0.9-1.8 times width of whitish stripe versus 0.3-0.6); distance from dorsal-fin origin to upper margin of whitish stripe about equal to distance from anal-fin origin to lower margin of black stripe (upper distance 0.9-1.2 times lower distance versus 1.8-2.7).

Found in a wide, shallow stream with fast current and sandy bottom (Ref. 41279).

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=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.0 ±0.2 se; based on size and trophs of closest relatives

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