Adults found on mud bottoms, from 305 (Ref. 2850) to 2,740 m depth (Ref. 2850). Young-of-the-year juveniles are pelagic and found on the surface and near-shore waters (Ref. 28499). Generally localized, but some juveniles have been found to migrate over 2,000 miles in 6 or 7 years (Ref. 28499). Feed on crustaceans, worms and small fishes (Ref. 4925). Most of the catch is marketed in Japan (Ref. 28499). Utilized fresh, dried or salted and smoked (Ref. 9988), can be steamed, pan-fried, broiled, boiled, microwaved and baked (Ref. 9988). The liver oil is rich in vitamin A and D (Ref. 4925). Reported to reach 57 kg in Ref. 2850.
