Short description Identification keys | Morphology | Morphometrics
Dorsal spines (total): 10 - 12; Dorsal soft rays (total): 18 - 20; Anal spines: 0; Anal soft rays: 13 - 16; Vertebrae: 35. Dorsal with moderate notches in the spinous part after the third spine, and between the spinous and rayed parts; caudal bluntly rounded; pelvic fins larger in males (Ref. 6885). Color variable, predominately red, sometimes brilliant red, with brown, white, and black mottling and spotting all over; there are four irregular dark saddles across back; the caudal fin with darker rays, sometimes with vertical light bars; some large males with darkly spotted pelvic fins (including base of pectorals) (Ref. 6885).
Usually near shore in rocky areas (Ref. 2850), from intertidal areas to 275 m depth (Ref. 6793). Adults feed on crabs, barnacles, and mussels (Ref. 6885). Good eating (Ref. 2850).

Estimates based on models
Preferred temperature (Ref. 123201): 0.9 - 7.7, mean 4.4 °C (based on 386 cells).
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00589 (0.00281 - 0.01234), b=3.15 (2.97 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278): 3.5 ±0.6 se; based on diet studies.
Resilience (Ref. 120179): Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153): Moderate vulnerability (40 of 100).
