Size / Vikt / Age

Maturity: L_m ? range ? - ? cm
Max length : 91.0 cm TL hane/ej könsbestämd; (Ref. 2850); publicerad maxvikt: 16.0 kg (Ref. 2850); rapporterad maxålder: 53 år (Ref. 56049)

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.

Estimates based on models

Preferred temperature (Ref. 115969): 16.6 - 22.9, mean 21.2 (based on 30 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 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).

Trofisk nivå (Ref. 69278): 3.6 ±0.43 se; based on food items.

Resiliens (Ref. 120179): Mycket låg, lägsta populationsfördubblingstid mer än 14 år (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.
