Morphology | Morphometrics
Very similar to eastern creek chubsucker Erimyzon oblongus, but has 9-11, usually 10 dorsal rays. Dorsal fin rounded. Presence of 5-8 dark blotches along side. Scales on lateral line 37-45 scales (Ref. 86798).
Inhabits silt-, sand- and gravel-bottomed pools of clear headwaters, creeks and small rivers, usually near submergent vegetation. Occasionally found in lakes (Ref. 86798).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5625 [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
): 3.0 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (33 of 100) .
