Wolf eel teeth5/1/2023 fishing vessels of Atlantic wolffish as bycatch has declined 95%, landing 64.7 metric tons in 2007. Recreational fishing has also threatened the survival of the Atlantic wolffish.Īccording to data compiled by the National Marine Fisheries Service, since 1983, the landings from U.S. The nets are indiscriminate in what they catch and the heavy weights and nets are harmful to the benthic terrain and its inhabitants. Bottom-trawling vessels also disrupt the wolffish's rocky underwater habitat when they drag large nets across the ocean floor, with heavy weights holding the nets to the ocean bottom. In Iceland, the species is called ''steinbítur'', which literally translates to "stone biter".Īccording to scientific data, the Atlantic wolffish's population has decreased drastically due to overfishing and bycatch. The oil extracted from the liver is said to be equal in quality to the best cod liver oil. They are marketed in Britain as "Scotch halibut" and "Scarborough woof", or, simply "woof" in other areas of the northeast coast, and are a popular ingredient in fish and chips. In the north, they are esteemed as food, both fresh and preserved. Two related species occur in the corresponding latitudes of the North Pacific Ocean. Since they live in nearly freezing waters, to keep their blood moving smoothly, it contains a natural antifreeze. They are usually found in waters of 34-37 ☏ and sometimes as low as 30 ☏. They like cold water, at depths of 76 to 120 meters. They are benthic dwellers, living on the hard ocean floor, frequently seen in nooks and small caves. The most dense populations are in Georges Bank, the Gulf of Maine and the Great South Channel.Ītlantic wolffish are primarily stationary fish, rarely moving from their rocky homes. Although they are seldom seen south of Cape Cod, there have been sightings in New Jersey. They are seen as far north as the Davis Strait, of the Canadian territory of Nunavut, populating the shores of Greenland and Nova Scotia, extending down as far as Cape Cod. The wolffish's throat is also scattered with serrated teeth.Ītlantic wolffish inhabit both the west and east coasts of the Atlantic. The lower jaw has two rows of molars behind the primary conical teeth. The central row has four pairs of molars and the outer rows house blunted conical teeth. Behind the conical teeth in the upper jaw, there are three rows of crushing teeth. Both the lower and upper jaws are armed with four to six fang-like, strong, conical teeth. Its dentition distinguishes the Atlantic wolffish from all the other members of the Anarhichadidae family. The Atlantic wolffish's distinguishing feature, from which it gets its common name, is its extensive teeth structure. Its obtuse, eel-like body type makes the fish swim slowly, undulating from side to side, like an eel. The pectorals are large and rounded and the pelvic fins are entirely absent. ![]() An even dorsal fin extends the whole length of the back, and a similar fin from the vent to the caudal fin, as in blennies. Atlantic wolffish vary in color, usually seen as purplish-brown, a dull olive green, or blueish gray. The largest specimen recorded measured 150 cm long and weighed almost 18 kg Its body is long, subcylindrical in front, compressed in the caudal portion, smooth and slippery, the rudimentary scales being embedded and almost hidden in the skin. ![]() In spite of its large size, the Atlantic wolffish has retained the bodily form and general external characteristics of small blennies. Wolffish population success is also an important indicator of the health of other bottom-dweller populations, such as cod. They are also an important factor in controlling green crab and sea urchin populations, which can become overly disruptive to habitats if left unchecked. Although it looks fearsome, the Atlantic wolffish is only a threat to humans when defending itself out of the water.Īpart from their unique appearance wolffish are distinguished by the natural antifreeze they produce to keep their blood moving fluidly in their very cold habitat, involvement by both the male and female in brood bearing, and the large size of their eggs. The numbers of the Atlantic wolffish are rapidly being depleted, most likely due to overfishing and bycatch, and is currently a Species of Concern according to the National Oceanic and Atmospheric Administration's National Marine Fisheries Service. e lkein to draw, drag, tear in pieces.The Atlantic wolffish, also known as the seawolf, Atlantic catfish, ocean catfish, devil fish, wolf eel, woof or sea cat, is a marine fish, the largest of the wolffish family Anarhichadidae.
