Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 11; Dorsal soft rays (total): 16 - 17; Anal spines: 3; Anal soft rays: 8. Juveniles are mostly yellow becoming gray with dark spots anteriorly. The gray area increases with increasing size until only the fins remain yellow on individuals of 15 to 20 cm (Ref. 37816).

Usually found around isolated coral heads in lagoons or bays, but also caught on outer reef area. According to Myers (1989, Ref. 4538) it usually swims out in the open, several meters above the bottom. It is readily caught by anglers at night. Feeds mainly on sand-dwelling fishes and crustaceans such as snake eels and box crabs. In Hong Kong live fish markets (Ref. 27253).

Estimates based on models

Preferred temperature (Ref. 123201): 22.5 - 29, mean 27.8 °C (based on 1250 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01122 (0.00702 - 0.01794), b=3.05 (2.92 - 3.18), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.1 ±0.5 se; based on diet studies.

Resilience (Ref. 120179): Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): High to very high vulnerability (73 of 100).

Price category (Ref. 80766): Very high.

Nutrients (Ref. 124155): Calcium = 15.1 [7.2, 34.0] mg/100g; Iron = 0.448 [0.226, 0.897] mg/100g; Protein = 18.4 [16.8, 19.9] %; Omega3 = 0.112 [0.067, 0.188] g/100g; Selenium = 51 [27, 103] μg/100g; VitaminA = 192 [50, 735] μg/100g; Zinc = 0.956 [0.646, 1.371] mg/100g (wet weight);
