Dorsale stekels (totaal) : 5 - 7; Dorsale zachte stralen (totaal) : 12 - 14; Anale stekels: 0; Anale zachte stralen: 11 - 12. Caudal rounded.

Found usually in sandy areas near rocks. Occurs from intertidal areas to 106 m depth. Retreats to rocks or holes when approached. Young are found usually offshore among plankton. Oviparous (Ref. 56079). A protogynous hermaphrodite (Ref. 34256). Forms permanent harem groups composed of a single male and several smaller females (Ref. 55367).

Protogynous (Ref. 13452, 35501). Sex reversal is completed in less than 5 months (Ref. 34185, 34256). A monandric species (Ref. 55367). Length at sex change = 6.9 cm TL (Ref. 55367). Also Ref. 103751.

Estimates based on models

Preferred temperature (Ref. 123201): 8.3 - 12.8, mean 9.8 °C (based on 66 cells).

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01023 (0.00477 - 0.02194), b=3.01 (2.83 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.4 ±0.58 se; based on food items.

Weerstandsvermogen (Ref. 120179): Gemiddeld, minimale populatieverdubbelingstijd 1,4-4,4 jaar (tmax=5).

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

Prijsklasse (Ref. 80766): Very high.

Nutrients (Ref. 124155): Calcium = 162 [79, 343] mg/100g; Iron = 1.32 [0.70, 2.56] mg/100g; Protein = 18.5 [16.6, 20.1] %; Omega3 = 0.4 [0.2, 0.7] g/100g; Selenium = 21.9 [10.9, 43.4] μg/100g; VitaminA = 18.8 [5.8, 59.0] μg/100g; Zinc = 1.06 [0.73, 1.59] mg/100g (wet weight);
