Morphology | Morphometrics
Chrosomus tennesseensis is similar to C. oreas but can be distinguished by having smaller spots (smaller than eye pupil) on back and upper side, usually a thin black stripe present along side (above larger broken stripe), red on caudal fin and below stripe along side of large make, and 67-95 scales on lateral line (Ref. 86798).
Found in gravel-, sand-, and silt-bottomed pools of spring-fed headwaters (Ref. 5723, 10294, 86798).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5078 [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
): 2.6 ±0.1 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 (18 of 100) .
