Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 3; Dorsal soft rays (total): 21 - 22; Anal spines: 3; Anal soft rays: 12 - 14; Vertebrae: 26 - 27. This species distinguished by the following characters: 21-22 (rarely 21) segmented dorsal-fin rays; 12-14 (rarely 12 or 14) segmented anal fin rays; weakly pungent to flexible anal spines, the second one varying from about as stout to less stout than the third; 29-35 (usually 30-33) scales in lateral series; 23-28 (usually 24-27) anterior lateral line scales; 10-12 scales below anterior lateral line; males with distinct coloration, head and body dark grey to black (dark brown to black when preserved), the lower part of head and body in front to anal-fin origin yellowish brown (when preserved pale brown to brown) (Ref. 81967).

Known from tidal pools and rock and coral reefs, common in high surge areas (Ref. 81967).

Estimates based on models

Preferred temperature (Ref. 123201): 25.9 - 27.8, mean 26.7 °C (based on 162 cells).

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

Bayesian length-weight: a=0.00501 (0.00193 - 0.01299), b=3.10 (2.88 - 3.32), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.5 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
