Max length : 10.2 cm SL male/unsexed; (Ref. 31667)
A species belonging to the C. fimbriatus species group which is distinguished mainly from its congeners by its very fine reticulate pattern on the dorsal surface, even in large individuals; with mainly 13 neuromasts in the pectoral series (vs. 12 or less in its congeners) and slightly more numerous neuromasts on the body proper, 33-38 (vs. 29-37) (Ref. 94130).
Benthic (Ref. 58302). A poorly known species which is apparently represented only by a few specimens collected from the Hawaiian Islands and the Emperor Seamount (Ref. 94130).

Estimates based on models
Preferred temperature (Ref. 123201
): 9.9 - 17.1, mean 15.1 °C (based on 5 cells).
Phylogenetic diversity index (Ref. 82804
= 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 BS (Ref. 93245
Trophic level (Ref. 69278
): 3.8 ±0.6 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (Assuming tmax>10).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (10 of 100).
