Body small and slender; boldly marked body with a pattern of distinct black lines on a pale brownish background. Origin of the first dorsal fin behind free rear tip of pelvic fin (Ref. 26938).
Found on the outer continental shelf and upper slope on rough, rocky bottom. Water temperature: 8.5-11.3°C. Food habits unknown. Oviparous. Not utilized at present. Found in waters 75-550 m deep (Ref. 26938). Lives at depths off 36-230m in the northern portion of its range, and in waters deeper than 460m in its southern range (Ref. 55294). Maximum depth reported taken from Ref. 55584.
Life cycle and mating behavior
