背面の脊椎 (合計) : 0; 肛門の骨: 0. A broad-headed catshark with crowded dark brown spots on a yellowish background, producing a net-like pattern of light lines; underside white with small black pores; no labial furrows (Ref. 5578). Specimens less than 23 cm TL blackish with white side spots (Ref. 5578).
Body shape (shape guide): elongated.
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).
