Morphology | Morphometrics
soft rays: 5 - 6. Head spines strong - nasal, preocular, supraocular, postocular, tympanic, parietal and nuchal spines present, coronals usually absent (Ref. 27437). Small lobes projecting from anterior part of upper jaw (Ref. 27437). Second anal fin spine long (Ref. 27437). Rose-red to pink dorsally, silvery on sides and ventrally (Ref. 27437).
Common offshore (Ref. 2850). Viviparous, with planktonic larvae and pelagic juveniles (Ref. 36715). Trawled on soft bottom and when caught scales usually rub off, leaving white pockets bordered by red; also caught in sablefish traps (Ref. 2850).
