(Sculpins) > Liparidae
Etymology: Careproctus: Greek, kara = face + Greek, proktos = anus (Ref. 45335); gilberti: Named for C.H. Gilbert, U.S. ichthyologist (Ref. 6885)
This species is possibly a synonym of Careproctus ostentum Gilbert, 1896 following Chernova et al. (2004: Ref. 51661). Please send references or more studies are needed.

Estimates based on models
Preferred temperature (Ref. 115969
): 3.7 - 6.4, mean 5.1 °C (based on 83 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00447 (0.00201 - 0.00993), b=3.17 (2.99 - 3.35), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.2 ±0.5 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 (12 of 100) .
