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).

Biologie     Verklarende woordenlijst (bv. epibenthic)

Estimates based on models

Preferred temperature (Ref. 123201): 9.9 - 17.1, mean 15.1 °C (based on 5 cells).
Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 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 body shape (Ref. 93245).
Trofisch niveau (Ref. 69278):  3.8   ±0.6 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref. 120179):  laag, minimale populatieverdubbelingstijd 4,5-14 jaar (Assuming tmax>10).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
