What Is Wolffish?

Last updated:

Wolffish are native to the North Atlantic Ocean. They are commonly known by other names, including seawolf, devil fish, and ocean catfish.

They are in the family Anarhichadidae. They are a popular sport fish. Sadly, the species is threatened by overfishing and other factors. Read on to find out more about this fish.



The wolffish, also known as the Atlantic catfish, devil fish, seawolf, or ocean catfish, is a fish native to the North Atlantic Ocean.

It belongs to the family Anarhichadidae. Like all family members, it lives in warm, shallow waters. Its name comes from its appearance and lack of fins.

The Atlantic wolffish has long, slender bodies with large teeth. They are also often confused with eels, due to their eel-like appearance and prominent teeth.

Although they look like eels, they are more closely related to sculpins than eels. They have voracious appetites and aggressive hunting techniques, but are not aggressive toward humans.

Wolffish is considered a delicacy in Iceland and Europe and a prized protein by Icelandics. This species has a sweeter flavor than other types of fish, and its meat is firm and meaty.

Its flavor comes from its diet of crustaceans. Niceland’s Arctic wolffish is certified sustainable by the Marine Stewardship Council and is available from March to September.

Male and female wolffish form bonded pairs. Their spawning season lasts between September and October.

Female wolffish lay thousands of eggs during this time, and males stay near to guard them until the eggs hatch. The eggs are 5.5 to 6mm in diameter and have an opaque yellowish tint.


Wolffish is found in the Atlantic and Pacific Oceans, in depths ranging from 1,000 to 2,000 feet. The sedentary lifestyle of these predators helps them ambush their prey with ease.

Unfortunately, several species of wolffish have been threatened by human beings.

Although they are rarely consumed in large numbers, accidental catches and habitat destruction have significantly declined their population.

Wolffish live in rocks and crevices near the bottom of the ocean. They are carnivores, eating shelled sea creatures and other invertebrates.

Their large jaws and teeth make them an effective predators. They can grow up to five feet long and 40 pounds in weight. They have a large head, sharp teeth, and a long, tapered body.

Their dorsal fin runs down their backs and has a smaller version of it on their underside.

Atlantic wolffish live in the waters off the coast of Europe. Their range includes the North Sea and waters surrounding the British Isles.

They can be found as far north as Davis Strait. They are also found off Greenland and Nova Scotia coast and extend south to Cape Cod.

Their range includes waters in the Bay of Biscay and the Russian White Sea.

The Atlantic wolffish is a predator of marine fish. They have razor-sharp teeth that extend across their throat. They can live for up to 20 years.

Their growth rate is relatively slow, with adults not reaching sexual maturity until they reach age eight or ten.

Wolffish reproduce in pairs in the spring and fall and fertilize their eggs differently than most other fish species.


Wolffish is a great source of nutrients and vitamins. Its flesh is sweet and tender and can be prepared in various ways. It has a delicate taste that has been compared to lobster.

Wolffish can be baked, fried, grilled, or even sauteed. It can be found in both the Atlantic and Pacific Oceans.

While this fish is a good source of protein, it can also cause arsenic poisoning if not prepared correctly.

Wolffish feed on a variety of prey. Although they are demersal carnivores, they also consume lower-trophic level organisms such as sea urchins, crustaceans, gastropods, and algae.

Their powerful jaws make them effective at tearing open shells and ingesting fragments.

In addition, wolffish appear to be opportunistic in their feeding habits and stop feeding during the annual teeth replacement and spawning season.

The wolffish lives in very cold waters and prefers to stay near the bottom of the ocean. They are often seen moving on the ocean floor in small caves or rock formations.

In addition to being extremely hard to see, wolffish are quite rare in the wild. The wolffish belongs to the family Anarhichadidae and is closely related to gunnels, quillfish, and eelpouts.

This family is one of the largest in the world and contains more than 10,000 species and 40% of all bony fish species.

Wolffish have a remarkable reproduction cycle, with a peak period in September and October. They form life-long mates and lay thousands of eggs during their lifetime.

Their eggs are 5.5 to 6mm in diameter and have an opaque yellowish tint.


Wolffish is a species of fish native to the Atlantic Ocean. Some have even been seen in New Jersey’s ocean waters.

They are primarily stationary fish in ocean depths of seventy-five to twenty-five feet.

They feed on hardshell crustaceans, mollusks, and echinoderms and spend much of their lives hiding in small caves.

The population of wolffish is declining. It is thought that overfishing may be the cause. The species is vulnerable to overfishing due to its late sexual maturity and high site fidelity.

Also, it is difficult to estimate their population, as they are sedentary and slow-growing.

The Atlantic wolffish is a large species native to the North Atlantic Ocean. It is easily recognizable due to the rows of fang-like teeth that stick out of its mouth.

It has a broad head and a body that tapers downward to its tail. Its color is a grayish-blue color.

Atlantic wolffish are found along the east and west coasts of the Atlantic. Their range extends from the waters of Greenland and Nova Scotia all the way down to Cape Cod.

Although they are rarely seen south of Cape Cod, wolffish have been reported in New Jersey. The species is protected by law in several parts of the world.

However, overfishing is a serious problem in many parts of the world.

In the Atlantic, the wolffish population is rapidly declining due to overfishing. They are not easily restocked; it can take as long as a decade to restore a healthy population.

Their slow sexual maturity rate makes them particularly vulnerable to human activity.

Habitat destruction

The Atlantic wolffish faces several threats to its continued existence. Among these threats is habitat destruction.

In addition, the species is particularly vulnerable to ocean acidification and rising ocean temperatures. Trawling by commercial fishing vessels is a major threat that could lead to significant habitat damage.

In addition to habitat destruction, trawling can also cause the capture of wolffish in fishing nets.

While Atlantic wolffish are now protected from commercial fishing, their populations continue to decline.

Atlantic wolffish decreased from 1,200 metric tons in 1983 to only 64.7 metric tons in 2007.

In addition, the species has virtually disappeared from annual scientific research trawls. Scientists suspect that the wolffish’s decline is due to habitat alterations.

One scientist estimated that commercial trawling altered every inch of the seafloor in New England between 1984 and 1990.

To protect wolffish populations, federal agencies must implement a recovery plan. They should designate critical habitats for wolffish.

Additionally, these fish should be listed as endangered species. This will help prevent further damage to their habitat. In the meantime, we can enjoy their delicious taste.

The Atlantic wolffish has many natural enemies. However, if climate change becomes a reality, this species could lose its spawning grounds in the southern portions of the GOM and Cape Cod.

In addition, sea surface waters could become so warm that the survival of aquatic larvae in November and December may be at risk.

Reproduction habits

Reproduction Habit of Wolfish

The reproduction habits of wolffish are quite unusual for a fish of this size. Unlike most fish, they only reproduce when they reach about eight to 10 years old.

Females fertilize their eggs internally and lay them on the seabed. The males guard the eggs until they catch them, usually in the fall.

However, this is not the unique feature of wolffish.

Atlantic wolffish are capable of living in a wide range of salinities. They can migrate between high and low salinity areas, and they can absorb and excrete salt ions.

In their mating rituals, female wolffish choose a suitable male by “courting” him in the water. The females then lay 5.5 to six-millimeter-long eggs that are fertilized internally.

The eggs of wolffish are about half an inch long when they hatch. The larvae of wolffish are 17 to 18 mm long and are encased in a net of blood vessels.

The larvae of wolffish are similar to those of salmon and trout.

Atlantic wolffish are often caught accidentally by fishermen. They are also at risk from otter trawling, which drags large nets along the ocean floor.

The large nets also destroy their habitat. Because the Atlantic wolffish’s population is so small, it can take up to a decade before it restocks.
