Etymology: Notropis: A misnomer given by Rafinesque to shriveled specimens, with the meaning of "back keel"; from Greek, noton = back (Ref. 45335); braytoni: Notropis meaning ridged or keeled back, and braytoni in honor of A.M. Brayton, who traveled with Jordan and Evermann in Georgia, North Carolina, and South Carolina (Ref. 79012).

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00501 (0.00237 - 0.01060), b=3.13 (2.95 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.9 ±0.3 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).
