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.
The five species in two genera are:Genus Anarhichas
Northern wolffish, Anarhichas denticulatus Krøyer, 1845.
Atlantic wolffish or sea wolf, Anarhichas lupus Linnaeus, 1758.
Spotted wolffish, Anarhichas minor Olafsen, 1772.
Bering wolffish, Anarhichas orientalis Pallas, 1814.
Wolf eel, Anarrhichthys ocellatus Ayres, 1855.
