Etymology: Noturus: Greek, noton = back + Greek, oura = tail; refred to the position of the tail over the back (Ref. 45335); maydeni: Named for Richard L. Mayden in recognition of his work on species concepts and his contributions to ichthyology, particularly the systematics and biology of central highlands fishes.

Inhabits clear, swift, moderate to large high gradient streams. Occurs in swift shallow riffles with gravel, cobble or large stone substrate, but can occasionally be found in shallower pools (Ref. 57745).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00324 - 0.03234), b=3.06 (2.81 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.3 ±0.4 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.).
Vulnerability (Ref. 59153
): Low vulnerability (12 of 100) .
