![]() This species is benthic, meaning that they live along the hard, rocky ocean floor and nest in small caves or nooks. The largest populations occur in the Great South Channel, Georges Bank, and the Gulf of Maine, and they are found in and near Stellwagen Bank National Marine Sanctuary. Their range spans the northern Atlantic Ocean, venturing as far north in the western Atlantic as the Davis Strait, Nunavut territory in Canada. To hunt, wolffish use ambush predation in which they remain still and attempt to blend into their environment so unsuspecting prey will approach them when they come close enough, the wolffish lunges, using their teeth to trap and their jaws to crush their prey.Ītlantic wolffish spend most of their time in a particular home range, but they do leave that range to find colder waters that are more suitable for spawning season. These fish are keystone species, which means their predation keeps other animal populations – like urchins, green crabs, and starfish – in check and their ecosystems in balance without Atlantic wolffish, these populations could grow too quickly and lead to smaller populations of important species that build the foundation of marine and coastal food webs. Common prey species include hermit crabs, urchins, green crabs, clams, and starfish. The strong jaws and large teeth that Atlantic wolffish have allow them to feed on hard-shelled organisms like crustaceans, mollusks, and echinoderms. ![]() This species can grow to be six feet long and weigh as much as 50 pounds! They have multiple rows of specialized teeth, which they lose and replace annually due to the damage their hard-shelled prey can cause over time.Ītlantic wolffish appear in a range of colors from olive-green, purplish-brown, or a striking blue-gray and a single dorsal fin span’s the fish’s entire back, and another spanning from its tailfin and along its ventral side. Their most notable features include the large teeth that protrude from their mouths even when closed. Known as wolf eels, Atlantic wolffish have long and slender eel-like bodies. The good news is that these incredible fish are pretty shy around humans and won’t use those chompers to bite unless they are provoked. Their intimidating appearance is matched by their voracious appetites and aggressive hunting strategies.
