Description synthétique Clés d'identification | Morphologie | Morphométrie

A species of the C. abei species group that differs from its congeners in having large spots on the dorsal surface; a largely naked area on abdomen; a relatively short head (27.0–29.8% SL) and a relatively long tail (tail length 1=34.0-35.6% SL), reflected in the relatively elongated body; dermal spines on body surface all simple, relatively slender and elongated; and relatively high lateral line neuromast counts, 39–50 (mainly 41–43) in lateral line proper, 3–5 (mainly 4) in upper peropercular series, and 15–19 (mainly 16–17) in pectoral series, which is well extended beyond pectoral fin base (Ref. 84087).

Estimates based on models

Preferred temperature (Ref. 123201): 2 - 3.9, mean 3 °C (based on 84 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01905 (0.00762 - 0.04763), b=3.02 (2.80 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 4.0 ±0.7 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
