Etymology: Panaqolus: Derived from Panaque, see.; nix: Name from the Latin nix meaning snow, in allusion to the color: in dark individuals the dots look like falling snowflakes, while pale individuals look like they have the whole body covered by snow. A noun in apposition..

Morphology | Morphometrics
Caught mostly in cofferdams at the construction sites of the hydroelectric power plants of Santo Antônio and Jirau (former Santo Antônio and Jirau rapids) in rio Madeira. Most specimens were collected at depths of 3.1-11 m and 4.1 to 8.5 m using trawl nets, indicating preference for deep-water habitats with strong current (Ref. 104707).

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00452 - 0.02316), b=3.04 (2.84 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
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).
