Found on the outer continental shelf and upper slope, on or near the bottom (Ref. 244). This species has been reported to prefer temperate to cool temperate waters, but may also be found in subtropical waters; apparently prefer 200-300 m depths on the west coast and 100-200 m depths on the south coast; and, a common by catch of demersal trawlers (Ref. 75585). Feeds mainly on pelagic bony fishes, also fish offal, hagfish eggs, crustaceans, and cephalopods (Ref. 5578). Oviparous (Ref. 50449).
