The Atlantic wolffish, also known as the seawolf, Atlantic catfish, ocean catfish, devil fish, wolf eel, woof or sea cat, is a marine fish of the wolffish family Anarhichadidae, native to the North Atlantic Ocean. The numbers of the Atlantic wolffish in US waters are rapidly being depleted, most likely due to overfishing and bycatch, and it is currently a Species of Concern according to the U.S. National Oceanic and Atmospheric Administration's National Marine Fisheries Service.
