Short description Morphology | Morphometrics

Dorsal spines (total): 13; Dorsal soft rays (total): 10; Anal spines: 7; Anal soft rays: 9; Vertebrae: 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.

Western Pacific: endemic to Fiji, with strays recorded from New Caledonia.

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 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=0.01278 (-0.18801 - 0.21356), b=3.13684 (3.02888 - 3.24479), based on LWR estimates for this family-BS (Ref. 93245).

Trophic Level (Ref. 69278): 2.7 ±0.30 se; Based on food items.

Resilience (Ref. 69278): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Vulnerability (Ref. 59153): Low vulnerability (17 of 100) .

Price category (Ref. 80766): High.
