Short description
Morphology | Morphometrics
Dorsal
spines
(total): 2. About 11 greyish brown dorsal saddle marks (indistinct posteriorly), commencing predorsally, the fifth saddle noticeably darker (brownish black); a narrow, black stripe of pigmentation running along anal fin near the ventral margin of the fin, indistinct anteriorly and posteriorly, darkest midway along fin; upper two-thirds of first dorsal fin darkly pigmented; ventral surface of head and lower jaw naked; small, oval dermal window of light organ separated from anus by one or two scale rows; orbit oval, large 31.8-43.6% HL; pyloric caeca 2-32 (Ref. 26363). Similar to a number of species (C. mystax, C. bollonsi, C. parvifasciatus, C. fasciatus, and C. cookianus) but may be differentiated from each other based on the pigmentation on the body or fins and in pyloric caeca counts, among other characters (Ref. 26363).
A benthic species (Ref. 75154) which inhabits upper slopes (Ref. 26363).

Estimates based on models
Preferred temperature (Ref.
123201): 9.2 - 13.6, mean 11.9 °C (based on 38 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00251 (0.00128 - 0.00492), b=3.19 (3.03 - 3.35), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.5 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (30 of 100).
