Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 13; Dorsal soft rays (total): 7; Anal spines: 3; Anal soft rays: 10. Large adults appear blue underwater and usually have a small black spot at the dorsal fin base. Juveniles have a large white saddle spot following the black spot (Ref. 48636). A moderately small but prominent dark spot present on body at base of last dorsal-fin spine (spot not extending onto fin membrane). Body scales each with a blue centre in life forming horizontal rows of spots on side. Second prominent anterior canine in lower jaw distinctly shorter than first in adults, directed mostly dorsally and slightly anteriorly. 3 to 5 scales on subopercle. (Ref 9823)

Biology     Glossary (e.g. epibenthic)

Inhabit flat sandy or weedy areas near lagoon and seaward reefs (Ref. 9710). Solitary. Feed mainly on hard-shelled prey including crustaceans, mollusks and sea urchins. Marketed mostly fresh. In Hong Kong live fish markets (Ref. 27253).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Estimates based on models

Preferred temperature (Ref. 123201): 24.5 - 29, mean 27.9 °C (based on 478 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01288 (0.00577 - 0.02877), b=3.05 (2.85 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.41 se; based on food items.
Generation time: 4.2 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (39 of 100).
Price category (Ref. 80766):   Very high.
Nutrients (Ref. 124155):  Calcium = 29.2 [17.1, 44.4] mg/100g; Iron = 0.517 [0.303, 0.893] mg/100g; Protein = 18.9 [16.0, 21.0] %; Omega3 = 0.123 [0.083, 0.189] g/100g; Selenium = 44.2 [27.5, 74.7] μg/100g; VitaminA = 46.1 [15.6, 155.2] μg/100g; Zinc = 0.975 [0.721, 1.477] mg/100g (wet weight);
