Short description

Dorsal spines (total): 13; Dorsal soft rays (total): 11-14; Anal spines: 3; Anal soft rays: 5 - 8; Vertebrae: 26. Head spines strong - nasal, preocular, postocular, tympanic and parietal spines present, supraocular, coronal and nuchal spines absent (Ref. 27437). Toothed knob in front of each upper jaw, deep notch between jaws (Ref. 27437). Caudal fin moderately indented (Ref. 6885). A red rockfish, silver ventrally (Ref. 27437). Branchiostegal rays: 7 (Ref. 36715).

Common offshore, on soft bottoms (Ref. 2850). Young occur in shallow water, often at surface under drifting kelp (Ref. 2850). Viviparous, with planktonic larvae and pelagic juveniles (Ref. 36715, 34817). The biggest individuals are sometimes found in markets where the flesh is sold as rockfish fillet (Ref. 27436). Rarely caught by anglers (Ref. 27436).)

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805)
PD₅₀ = 0.5000 many relatives (e.g. carps) 0.5 - 2.0 few relatives (e.g. lungfishes)

Trophic Level (Ref. 69278)
3.7 ±0.6 se; Based on size and trophs of closest relatives

Resilience (Ref. 69278)
Low, minimum population doubling time 4.5 - 14 years (tm=5; tmax=86; Fec=14,000)

Vulnerability (Ref. 59153)
High to very high vulnerability (66 of 100)
