Max length : 120 cm TL Männchen/unbestimmt; (Ref. 247)

Found near shore on the continental shelf, more commonly on rocky and kelp-covered bottom (Ref. 43278, 11230). Feeds on crustaceans, mollusks (including top shells), small fishes and sea urchins. Oviparous (Ref. 43278, 50449). Grabs prey by protruding its jaw with considerable distance.

Life cycle and mating behavior Geschlechtsreife | Fortpflanzung | Ablaichen | Eier | Fecundity | Larven

Oviparous. Eggs are laid in rocks or in kelp at depths of about 8 or 9 m and are present from March through September. Eggs are more abundant, however, in March and April. Eggs are hatched in about a year; size at hatching is about 18 cm. There may be a `nest' for several females laying eggs but this is not a true nest. A female lays two eggs at a time, for 6 to 12 spawnings.

Estimates based on models

Preferred temperature (Ref. 115969): 16.6 - 23.5, mean 20.5 (based on 50 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5059 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00380 (0.00166 - 0.00872), b=3.15 (2.95 - 3.35), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.6 ±0.53 se; based on food items.

Widerstandsfähigkeit (Ref. 120179): niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (Fec=12).

Fishing Vulnerability (Ref. 59153): High to very high vulnerability (72 of 100).

Preiskategorie (Ref. 80766): Unknown.
