Short description Bestämningsnycklar | Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt) : 13; Mjukstrålar i ryggfenan (totalt) : 10; Taggstrålar i analfenan: 7; Mjukstrålar i analfenan: 9; Ryggkotor: 23. Color dark purplish brown except pectoral fins, soft portions of dorsal and anal fins, caudal fin, and posterior part of body; demarcation of 2 colors is sharp. Preopercular angle 110°-114°; strong overlapping scales cover cheeks, 9-10 rows deep below center of orbit; midline of thorax fully scaled. Spines stout, pungent and venomous. Snout slightly shorter and less tubular, less concave above the nostrils. Caudal fin slightly incised.

Found among hard corals at the faces of drop-offs at reef edges or in deep pools inside reef crests. Juveniles form schools, adults occur in pairs. Feeds on seaweeds (Ref. 9813).

Estimates based on models

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=3.08 (2.90 - 3.26), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 2.7 ±0.30 se; based on food items.

Resiliens (Ref. 120179): Hög, lägsta populationsfördubblingstid mindre än 15 månader (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (14 of 100).

Price category (Ref. 80766): High.

Nutrients (Ref. 124155): Calcium = 47.1 [22.5, 113.0] mg/100g; Iron = 0.745 [0.358, 1.799] mg/100g; Protein = 18.7 [17.2, 20.3] %; Omega3 = 0.116 [0.060, 0.234] g/100g; Selenium = 21.3 [8.5, 53.6] μg/100g; VitaminA = 34.9 [9.3, 122.6] μg/100g; Zinc = 1.31 [0.51, 2.80] mg/100g (wet weight);
