Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 2; Dorsal soft rays (total): 9; Anal spines: 4; Anal soft rays: 36 - 43. Large eyes, orbital diameter equal to or slightly longer than snout length. Gibbosity very pronounced.

Is a predator whose main food is not known. Appears to prefer an environment with fast current over rocky bottom which is typical of the rapids. Frequently found in the upstream areas of rivers (Ref. 12225).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5002 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01122 (0.00496 - 0.02540), b=3.07 (2.89 - 3.25), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.9 ±0.6 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).
