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.
Eponymy: Dr Richard Lee Mayden (d: 1955) is an American ichthyologist and systematic biologist. [...] (Ref. 128868), visit book page.

Rückenflossenweichstrahlen (insgesamt) : 7; Afterflossenweichstrahlen: 15 - 17; Wirbelzahl: 40 - 43.

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. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.4 se; based on size and trophs of closest relatives

Widerstandsfähigkeit (Ref. 120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).

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