Short description Morphology | Morphometrics

Dorsal spines (total): 0; Anal spines: 0; Vertebrae: 139 - 146. Flanges on upper and lower lips well developed; 2 rows of teeth in jaws, those of outer row larger; closely set and compressed to form cutting edge; 6th infraorbital pore located close behind and slightly above posterior angle of jaw. Dorsal fin begins over middle of appressed pectoral fin (Ref. 11039, refer to key for other characters). Brownish grey, yellow below and on fins, median fins with narrow black edge, black patch on lower rear edge of eye and on pectorals (Ref. 5323); assumes a pattern of broad dark bands at night (see also Ref. 4538, 1602). Body depth at gill opening 17-23 in TL (Ref 90102).

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

Indo-Pacific: Red Sea and East Africa to the Marquesan and Easter islands, north to southern Japan and the Ogasawara Islands, south to northern Australia and Lord Howe Island; except in Hawaii, where former subspecies C. marginatus is found.

Biology     Glossary (e.g. epibenthic)

Solitary species common on reef flats and seagrass beds of shallow lagoons but ranges to depths of 80 m on outer reef slopes (Ref. 1602). Also found in estuaries (Ref. 5213). Feeds on fish and crustaceans at night, assuming a pattern of broad dark grey bars (Ref. 11441).

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=0.00071 (0.00037 - 0.00134), b=3.16 (2.98 - 3.34), based on LWR estimates for species & Subfamily-BS (Ref. 93245).
Trophic Level (Ref. 69278):  4.4   ±0.8 se; Based on diet studies.
Resilience (Ref. 69278):  Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  High to very high vulnerability (72 of 100) .
Price category (Ref. 80766):   Medium.
