Size / Weight / Age

Maturity: L m   ?   range ? - ? cm
Max length : 91.0 cm TL male/unsexed; (Ref. 2850 ); max. published weight: 16.0 kg (Ref. 2850 ); max. reported age: 53 years (Ref. 56049 )

Biology     Glossary (e.g. epibenthic)

Prefer rocky bottom, particularly in kelp beds. Often feed on hard-shelled organisms such as sea urchins, mollusks, lobsters and crabs. Spawning occur during the summer and the eggs are pelagic (Ref. 9311 ). Live to more than 50 years of age. Each individual functions first as a female but changes to a male at a length of about 30 cm. Pelagic spawners (Ref. 56049 ). Flesh is white, of good quality and marketed fresh (Ref. 9311 ). The large teeth can cause serious bite wounds.

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

A diandric species (Ref. 55367 ). Transforms to a male at length of about 30.1 cm TL and 7.9 years of age (Ref. 55367 ). Forms leks during breeding (Ref. 55367 ). Pelagic spawner (Ref. 56049 ).

Estimates based on models

Preferred temperature (Ref. 123201 ): 16.6 - 22.9, mean 21.2 °C (based on 30 cells). Phylogenetic diversity index (Ref. 82804 ):  PD 50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00955 (0.00456 - 0.02002), b=3.06 (2.89 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245 ). Trophic level (Ref. 69278 ):  3.6   ±0.43 se; based on food items. Generation time: 6.5 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies. Resilience (Ref. 120179 ):  Very Low, minimum population doubling time more than 14 years (tmax=53; tm=5; Fec=300,000). Fishing Vulnerability (Ref. 59153 ):  Moderate to high vulnerability (55 of 100). Climate Vulnerability (Ref. 125649 ):  Very high vulnerability (78 of 100). Price category (Ref. 80766 ):   Very high . Nutrients (Ref. 124155 ):  Calcium = 17.8 [8.7, 35.2] mg/100g; Iron = 0.485 [0.267, 0.889] mg/100g; Protein = 19.5 [16.7, 21.7] %; Omega3 = 0.187 [0.109, 0.324] g/100g; Selenium = 19.1 [9.5, 37.2] μg/100g; VitaminA = 36.7 [11.3, 141.8] μg/100g; Zinc = 0.684 [0.467, 1.110] mg/100g (wet weight);
