Épines dorsales (Total) : 15 - 16; Rayons mous dorsaux (Total) : 8 - 10; Épines anales: 3; Rayons mous anaux: 4 - 6. Head spines very strong - nasal, preocular, supraocular, postocular, tympanic, parietal and nuchal spines present, coronal spines absent (Ref. 27437). Spiny ridge on sub-orbital bone; gill chamber mostly dark; third dorsal spine longest; slight notch on pectoral fin (Ref. 27437). Caudal fin slightly rounded (Ref. 6885). Red rockfish with some black on fins (Ref. 27437).
Adults occur on soft bottom of offshore waters (Ref. 2850). Juveniles occur in midwater (Ref. 2850). Oviparous (Ref. 205). Eggs are spawned in pelagic gelatinous masses (Ref. 59312).
