Short description Morphology | Morphometrics

Dorsal spines (total): 15 - 17; Dorsal soft rays (total): 8-9; Anal spines : 3; Anal soft rays : 4 - 5. Head spines very strong - nasal, preocular, supraocular, postocular, tympanic, parietal and nuchal spines present, coronal spines absent; large head and elongate body; strong spiny ridge on head; 3rd dorsal spine not much longer than 2nd, 4th or 5th; strong notch on pectoral fin (Ref. 27437 ). Bright red with some black on fins; gill chamber mostly pale (Ref. 27437 ). Caudal slightly rounded (Ref. 6885 ).

Biology     Glossary (e.g. epibenthic)

Very common on soft bottoms (Ref. 2850 ). Oviparous (Ref. 205 ). Eggs are extruded in floating gelatinous masses (Ref. 31279 ). Have a thick glandular tissue on posterior margin of fin spines which is believed to be venomous (Ref. 57406 ). Rarely taken by game fishers (Ref. 27436 ). Flesh sweeter than that of other rockfishes (Ref. 27436 ).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Unlike other representatives of this group, this species has internal fertilization Oviparous (Ref. 6885 ). Females possess specialized ovarian structures including stalk-like ovigerous lamellae and secretory epithelia (Ref. 32832 ).

Estimates of some properties based on models

Preferred temperature (Ref. 115969 ): 1.2 - 6.7, mean 3.8 (based on 417 cells). Phylogenetic diversity index (Ref. 82805 ):  PD 50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00708 (0.00405 - 0.01239), b=3.16 (3.00 - 3.32), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245 ). Trophic Level (Ref. 69278 ):  3.6   ±0.3 se; Based on diet studies. Resilience (Ref. 69278 ):  Very Low, minimum population doubling time more than 14 years (tmax> 100 (validated age: 62 yrs); tm= 13; Fec > 10,000). Prior r = 0.02, 95% CL = 0.01 - 0.03, Based on 1 stock assessment. Vulnerability (Ref. 59153 ):  High to very high vulnerability (70 of 100) . Price category (Ref. 80766 ):   Very high .
