The species has a smooth, silvery-brown body with white spots, large pectoral fins, large eyes and a tapering, rat-like tail, and reaches about one metre. It lives near the bottom, from just offshore to over 900 metres deep, and is abundant in cold water at moderate depths. The diet consists of mollusks, crustaceans, fishes, echinoderms and worms.
