Interorbital space flat to barely convex; symphyseal knob weak or absent (Ref. 27437). Caudal fin rounded (Ref. 6885). Light brown, mottled with one or two shades of darker brown, vague dark bars dorsally, dark brown blotch on upper part of gill cover; fins and underside of throat and lower jaw pinkish (Ref. 27437).

Biology     Glossary (e.g. epibenthic)

A sedentary rockfish found in shallow water and bays (Ref. 2850), among sheltering weed-covered rocks or around pilings (Ref. 27436). Viviparous, with planktonic larvae and pelagic juveniles (Ref. 36715). Fin spines are sharp and mildly venomous and can cause annoying wounds (Ref. 27436). Small live specimens make excellent bait for large lingcod (Ref. 27436). Flesh is firm and tasty, but rarely found in markets (Ref. 26346).

Estimates based on models

Preferred temperature (Ref. 123201): 8 - 12.8, mean 9.7 °C (based on 80 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00499 - 0.02004), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.0   ±0.62 se; based on food items.
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (tmax=34; tm=5).
