Morphology | Morphometrics
Distinguished from other hardyheads by a combination of the following characters (expressed in mean): greatest body depth (mean 4.9), least body depth (mean 10.3) both in SL; eye 3.0 in head; midlateral scale count (mean 31.4). Osteologically diagnosed by the combination of the following: dentition, shape of urohyal, medial wing of pelvic bone and premaxilla. Differs further in lacking ventral processes on fifth ceratobranchial for attachment of pharyngoclavicularis internus muscle (Ref. 26685).
Inhabits warm water (>20°C) of spring-fed pools. Upper temperature tolerance is probably not as high as C. dalhousiensis. Omnivorous. Only co-occurs with C. dalhousiensis in one spring (Ref. 44894).

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), 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
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (10 of 100).
