Short description Morphology | Morphometrics

Dorsal spines (total): 13; Dorsal soft rays (total): 13-14; Anal spines: 3; Anal soft rays: 6 - 8. Head spines strong - nasal, preocular, postocular, tympanic and parietal spines present, supraocular, coronal and nuchal spines absent (Ref. 27437). Parietal ridges very high and thick (Ref. 27437). Mouth small (Ref. 27437). Caudal fin rounded (Ref. 27437). Body blue or black, mottled with yellow; some individuals white ventrally; a broad yellow stripe from about the 3rd dorsal spine runs into or along the lateral line (Ref. 27437). Pelvic, anal and caudal fins are dark (Ref. 27437).

Biology     Glossary (e.g. epibenthic)

A territorial species occurring on the open coast, among rocks and reefs (Ref. 2850). Has mildly venomous spines (Ref. 27436). Viviparous (Ref. 34817). One of the tastiest rockfishes (Ref. 2850) but rarely found in markets because it is rarely caught (Ref. 27436).
