Short description Morphology | Morphometrics

Dorsal spines (total): 8; Dorsal soft rays (total): 25-28; Anal spines: 3; Anal soft rays: 22 - 25. C. strigosus differs from C. striatus by having a more truncate tail and a pale yellowish ring around the eye (Ref. 37816). Yellow on edge of orbit broad and conspicuous (pale in preservative), especially posteriorly. Small spots on head blue, not extending onto anterior body or chest. Posterior gill rakers 30-36 (Ref 42056).

Distribution Countries | FAO areas | Ecosystems | Occurrences | Introductions | Faunafri

Eastern Central Pacific: endemic to the Hawaiian Islands and Johnston Island. Western Central Pacific: Australia (Ref. 2334).

Biology     Glossary (e.g. epibenthic)

Benthopelagic over coral, rock, and rubble (Ref. 58302). Solitary. Mainly diurnal (Ref. 4887). Feeds on detritus by whisking its comb-like teeth over the bottom as it closes its mouth (Ref. 3921).

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5020   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01878 (-0.10345 - 0.14100), b=3.01 (2.94 - 3.09), based on LWR estimates for species & family-BS (Ref. 93245).
Trophic Level (Ref. 69278):  2.0   ±0.00 se; Based on food items.
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (K=0.9).
Vulnerability (Ref. 59153):  Low vulnerability (20 of 100) .
Price category (Ref. 80766):   Medium.
