Marine; reef-associated; depth range 0 - 549 m (Ref. 6793), usually 24 - 46 m (Ref. 2850). Temperate; 62°N - 32°N, 167°W - 117°W
Northeast Pacific: Unalaska Island, Alaska to San Diego, California, USA.
Length at first maturity / Size / Weight / Age
Maturity: Lm 36.0, range 27 - 42 cm
Max length : 66.0 cm TL male/unsexed; (Ref. 4925); max. published weight: 2.5 kg (Ref. 40637); max. reported age: 64 years (Ref. 39247)
soft rays: 7 - 9. Head spines weak - nasals present, preocular and parietal spines usually absent, supraocular, postocular, tympanic, coronal and nuchal spines absent (Ref. 27437). May have a prominent symphyseal knob; posterior edge of anal fin vertical (Ref. 27436). Caudal fin nearly truncate but slightly forked (Ref. 6885). Olive green to greenish brown with some light mottling dorsally, light ventrally; fins yellowish green, ventral fins often tinged in orange (Ref. 27436).
Form schools in open water along steeply sloping shores or above rocky reefs; also holes up amid cracks and crevices of the sea floor (Ref. 27436). Juveniles found around floats and pilings (Ref. 27436). Feed on pelagic crustaceans, fishes and squids (Ref. 6885). Viviparous (Ref. 34817). Filleted, then sold fresh or frozen, with other rockfishes (Ref. 27436).

Bayesian length-weight: a=0.01000 (0.00492 - 0.02031), 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
): 4.2 ±0.6 se; based on diet studies.
Resilience (Ref. 120179
