Main Ref. Holthuis, L.B., 1991
Remarks Occurs at depths of 0 to 200 m on rocky or gravel bottom, being most numerous in the kelp zone between 10 and 40 m (Ref. 4). Found clinging to overhangs in deep shade underneath huge rocks; also in caves (Ref. 106858). Confined to oceanic islands and seamounts (Ref. 105202). It is nocturnal and feeds on plants and dead animal matter (Ref. 4). Partially vegetarian (Ref. 105260). Reported to exhibit cannibalism among its deep-water populations (Ref. 105202).
