Short description Morphology | Morphometrics

Dorsal spines (total): 1; Dorsal soft rays (total): 5-6; Vertebrae: 30 - 32. Diagnosis: labial disk rather small (although larger than that of C. benuensis), transversally oval, provided with thick papillae and very long barbels; 3-5 auxiliary barbels on either side of lower lip and often another one at inner side of main outer mandibular barbel; premaxillary teeth well developed and arranged in 3-4 irregular rows; mandibular teeth large, numbering 3+3 to 4+4; adipose fin long, beginning distinctly ahead of anal-fin origin; caudal peduncle not very elongate, moderately slender; caudal fin slightly notched/moderately forked, lower lobe longer than upper; eye large; largest specimens have epidermic tubercles arranged in longitudinal lines on top of head; no obvious sexual dimorphism noted (Ref. 57223, 81251). Pupil of eye with flattened upper margin and contractile in living specimens (Ref. 81251). Coloration: fresh specimens with dark vertical bars on sides, separated by paler areas; ventral region entirely pink or salmon-coloured (Ref. 57223, 81251).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.2   ±0.4 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.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
Price category (Ref. 80766):   Unknown.
