Anarhichadidae

The wolffish, also known as sea wolves, are a family, Anarhichadidae, of perciform fish. They are native to cold waters of the northern Atlantic and Pacific Oceans, where they live on the continental shelf and slope, to depths of about 600 m (2,000 ft). They are bottom-feeders, eating hard-shelled invertebrates such as clams, echinoderms, and crustaceans, which they crush with their strong canine and molar teeth. The longest species, Anarrhichthys ocellatus, grows to more than 2 m (6.6 ft) in length.
