Các tia vây lưng cứng (tổng cộng): 0; Tia cứng vây hậu môn 0. Nostrils anterior to eye by about one-third of snout length. Pyloric caeca 6 to 8. Color reddish pink becoming paler ventrally, vertical fins with dark margins; a dark black blotch on the pectoral fin base.
Found usually on soft muddy or sandy bottoms. Also on rocky bottoms, in estuaries, bays and continental shelf (Ref. 9563). In New Zealand, most abundant in 200 to 300 m along the edge of the continental shelf. May be found at depths exceeding 700 m (Ref. 9258). Feeds primarily on fishes, cephalopods, crabs and other crustaceans. Utilized as frozen fillets as well as fish blocks; eaten steamed, fried, microwaved and baked (Ref. 9988).
