[7], According to data compiled by the National Marine Fisheries Service, since 1983, the landings from U.S. fishing vessels of Atlantic wolffish as bycatch has declined 95%, landing 64.7 metric tons (mt) in 2007. From Scott and Scott, 1988, p. 432. The Atlantic wolffish's distinguishing feature, from which it gets its common name, is its extensive teeth structure. Conservation Law Foundation, DR. Erica Fuller and Dr. Les Watling. They are an important predator of sea urchins and green crabs, whose populations escalate rapidly and can negatively affect the health of a marine system. [3] 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. Its obtuse, eel-like body type makes the fish swim slowly, undulating from side to side, like an eel.[2]. Atlantic Wolffish.

Behind the conical teeth in the upper jaw, there are three rows of crushing teeth. Its dentition distinguishes the Atlantic wolffish from all the other members of the family Anarhichadidae. Large teeth and powerful jaws allow this species to feed on various hard-shelled invertebrates. Atlantic Wolffish colouration can vary, depending on the environment, from slate blue to dull olive green and their upper body typically has ten or more irregular s… Wolffish population success is also an important indicator of the health of other bottom-dweller populations, such as Atlantic cod.

These benthic dwellers often take up residence in small caves and hidden crevices, far from the reaches of potential predators. The eggs are then laid on the seabed and the male will stay nearby and guard the eggs until they catch, which may take several weeks or even months. Species. They like cold water, at depths of 20 to 500 m (66–1,640 ft). [2], The Atlantic wolffish has retained the bodily form and general external characteristics of small blennies (Blennioidei).

They are also an important factor in controlling green crab and sea urchin populations, which can become overly disruptive to habitats if left unchecked. The Atlantic wolffish can be distinguished from the other two wolffishes of the region by the nine to thirteen irregular and broken dark transverse bars on its body, some of which extend onto the dorsal fin. They effectively use these teeth to feast upon hard-shelled invertebrates like crabs and sea urchins. Sea urchins are a favorite food of the striped wolffish. "Fishes of the Gulf of Maine."

Atlantic wolffish have a tapered body shape with a large rounded head and a slender tail. The female wolffish fertilize their eggs themselves, which may range between 5000 and 12,000 eggs. Since they can live in near-freezing waters (salt water only freezes at slightly below 0 °C or 32 °F), to keep their blood moving smoothly, they contain a natural antifreeze. Both the lower and upper jaws are armed with four to six fang-like, strong, conical teeth. A wolffish’s diet primarily consists of molluscs and crustaceans as opposed to other fish. The Atlantic wolffish (Anarhichas lupus), also known as the seawolf, Atlantic catfish, ocean catfish, devil fish, wolf eel (the common name for its Pacific relative), woof or sea cat, is a marine fish of the wolffish family Anarhichadidae, native to the North Atlantic Ocean.
