Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 9; Dorsal soft rays (total): 28 - 32; Anal spines: 3; Anal soft rays: 20 - 22. This species can be distinguished from its congeners by the following set of characters: D IX, 28-32 (mode 29); A III, 20-22 (mode 21); a single ocellated spot on soft-rayed portion of dorsal fin; absence of ocellated spot on anal fin; band on caudal peduncle usually orange when fresh (obscured in preserved specimens) with a short, saddle-like, blackish dorsal streak; a sharply pointed pelvic fin with an nearly straight posterior contour when spread (most obviously in large specimens >10 cm SL); presence of dark band on each interopercle joining on ventral midline with anterior margins forming a sharply pointed "V" in ventral view (Ref. 128188).
Most specimens were obtained using trawls from depths greater than 34 m; while juveniles occur in shallow coastal waters in that region. Since no differences in dentition were apparent between C. chrysozonus, which feed on sponge tissue and benthic invertebrates, and C. calendula, it is likely that both have a similar dietary habit (Ref. 128188).

50 = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02239 (0.01097 - 0.04568), b=3.01 (2.84 - 3.18), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
