Maturity: Lm ?  range ? - ? cm
Max length : 33.0 cm TL male/unsexed; (Ref. 2334)

Short description Morphology | Morphometrics

Dorsal spines (total): 8 - 9; Dorsal soft rays (total): 22-33; Anal spines: 2-3; Anal soft rays: 18 - 31; Vertebrae: 22. Body varying from light bluish grey to dark brown, without blue lines. Outer part of pectoral fins abruptly white, the demarcation curved such that pale area is broadest on central part of fin. Least depth of caudal peduncle 3.1 to 3.3 times in head length. Maximum standard length about 33 cm (Ref 9808).

Biology     Glossary (e.g. epibenthic)

Found off steep outer-reef escarpments. May be solitary but most commonly seen in small aggregations feeding on zooplankton well off the bottom.

Estimates based on models

Preferred temperature (Ref. 123201): 24.7 - 28.4, mean 26.3 °C (based on 333 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01445 (0.00650 - 0.03213), b=2.99 (2.79 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.45 se; based on food items.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (23 of 100).
Nutrients (Ref. 124155):  Calcium = 54.5 [24.6, 203.9] mg/100g ; Iron = 0.796 [0.280, 2.047] mg/100g ; Protein = 19 [18, 20] % ; Omega3 = 0.141 [0.062, 0.322] g/100g ; Selenium = 12.8 [4.2, 42.7] μg/100g ; VitaminA = 122 [48, 309] μg/100g ; Zinc = 2.32 [0.73, 4.45] mg/100g (wet weight);
