Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 4 - 6; Dorsal soft rays (total): 8 - 13; Anal spines: 1; Anal soft rays: 13 - 15. Mouth barely protractile and with thin lips. Basihyal and mesopterygoids usually with teeth. No notch present at the anterior border of preopercular bone. Face with Shangreen denticles. Ascending process of premaxilla with no lateral processes present. Distal end of maxilla blunt and truncate.

Loose aggregations inhabit tide pools and rocky shorelines and reef margins. Eggs are large.

Estimates based on models

Preferred temperature (Ref. 123201): 26.2 - 29.3, mean 28.7 °C (based on 1520 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.45 se; based on food items.

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

Nutrients (Ref. 124155): Calcium = 186 [94, 402] mg/100g; Iron = 0.987 [0.515, 1.791] mg/100g; Protein = 19.2 [16.9, 21.6] %; Omega3 = 0.124 [0.050, 0.339] g/100g; Selenium = 13.5 [6.0, 37.3] μg/100g; VitaminA = 331 [96, 1,081] μg/100g; Zinc = 2.16 [1.34, 3.37] mg/100g (wet weight);
