Short description Identification keys | Morphology | Morphometrics

This species differs from C. granoei and C. melanoleuca by the following characters: small meniscus lamina circularis at the base of the 1st branched pectoral fin ray in males (vs. knife lamina circularis in C. melanoleuca; larger semilunar lamina circularis in C. granoei); slender and straight suborbital spine, with long processus latero-caudalis, less than one-second of the processus medio-caudalis (vs. thick and straight suborbital with short processus latero-caudalis in C. melanoleuca; slender and curved suborbital spine with long processus latero-caudalis in C. granoei); and upper jet black spot pigmentation at the base of caudal fin inconspicuous or absent (vs. conspicuous in C. melanoleuca and C. granoei) (Ref. 128861).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00513 (0.00234 - 0.01125), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this Genus-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).
