Short description Morphology | Morphometrics

Dorsal spines (total): 9; Dorsal soft rays (total): 31; Anal spines: 3; Anal soft rays: 25 - 26. Resembles C. fulvoguttatus, but can be distinguished by the naked area of the breast extending up to the pectoral fin base, and the tip of the upper jaw located almost on a level with the lower margin of the eye. The spots on the sides are fewer than in C. fulvoguttatus. Attains 70 cm in SL.

Indo-West Pacific: Red Sea and East Africa to New Caledonia, north to the Ryukyu Islands, south to the Great Barrier Reef. Recently reported from Tonga (Ref. 53797).

Biology     Glossary (e.g. epibenthic)

Inhabits deep offshore reefs (Ref. 9710, 48635). Found near corals and rocks. Juveniles form small schools. Large individuals solitary. Feeds on shrimp and small fish (Ref. 5213). Excellent food fish (Ref. 12484).

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02523 (-0.06633 - 0.11678), b=2.91407 (2.85195 - 2.97618), based on LWR estimates for species & genus-BS (Ref. 93245).
Trophic Level (Ref. 69278):  4.1   ±0.72 se; Based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Moderate vulnerability (44 of 100) .
Price category (Ref. 80766):   Medium.
