Fun Wolffish Facts For Kids
Gallery
The wolffish, also known as the Atlantic wolffish, has the scientific name Anarhichas lupus and is a type of aquatic long-bodied fish belonging to the family Anarhichadidae and the order of mail-cheeked fishes. The wolffish belongs to one of five species of large long-body aquatic fishes.
They are most often spotted in the waters of the North Atlantic Ocean and Pacific waters.
Atlantic wolffish are purplish-brown, a dull olive green, or blueish gray in color. They have a long and large body with a powerful jaw, a large hard-shelled head, and large canine teeth which they make use of while hunting and eating hard-bodied (spiny body) invertebrates.
Atlantic wolffish are not particularly good-looking fish when it comes to their appearance. They prey on mollusks, crustaceans, sea urchins, crabs, large marine snails, and echinoderms.
A wolffish is 5 ft (1.5 m) long and weighs about 40 lb (18 kg). However, the largest species of the wolffish population may grow to a length of 7.5 ft (2.3 m)!
Wolffish reproduce by laying eggs. Wolffish are usually solitary fish but they do form pairs during their breeding season and, once mating is complete (using internal fertilization), the female lays eggs. Once the eggs have been laid, both partners guard the eggs until they hatch.
This fish is considered to be a species of concern in the United States.
The conservation status of Atlantic wolffish has been termed as Not Extinct. Wolffish are also exposed to threats from many aquatic predators like Greenland sharks, Atlantic cod, and haddock, so the wolffish is sadly under the threat of becoming extinct.
According to many ecologists, the Atlantic wolffish plays a major role in the food web in the North Atlantic ocean as it helps a lot in regulating the population of sea urchins and invertebrates, so losing this species will have a large impact.
Humans do eat wolffish and, since their skin is edible, humans can easily cook them and transform them into a delicious meal. The fish is said to have a sweet and satisfying taste.
Here on our page, we have lots of interesting facts on wolffish that everyone can enjoy. Let's have a look at these interesting facts and if you do like these, then do read our guide to the skate fish and fangtooth fish too.
