Atlantic wolffish reproduce through internal fertilization Their bodies excrete salt ions in high-salinity areas and absorb them in low-salinity areas. Atlantic wolffish are able to move between areas of higher and lower salinity without damage. They can live in different salinitiesįew fish can survive when the salinity, or concentration of salt, in the water around them changes. A natural antifreeze runs in their bloodĪtlantic wolffish create proteins that enable them to survive in extremely cold temperatures without damaging their body systems. They are found in waters as cold as 0° Celsius (32° Fahrenheit) and may be able to withstand temperatures that are even lower. Water temperatures can drop dramatically during the winter, but this does not impede Atlantic wolffish. Atlantic wolffish live in very cold waters This provides them with ample access to the prey that make up their diet. Unlike other fish who swim up and down in the water column, these fish prefer to make their homes on the rocky floor of the ocean. Once an Atlantic wolffish has found a suitable habitat in a cave or crevice, it rarely leaves that area. This species is a weak swimmer and lacks the pectoral fins that help other fishes move easily through the water. Atlantic wolffish are primarily stationary Some have been found in areas as deep as 500 meters (more than 1600 feet). They prefer different water depthsĪtlantic wolffish can be found on the ocean floor in both shallow and deep water. Their diet consists primarily of invertebrates with hard shells such as crabs, sea urchins, mussels, and whelks. One might expect Atlantic wolffish to prey on other fish, but this is not generally the case. Atlantic wolffish don’t usually eat other fish Their throats have a series of sharp serrated teeth that help the wolffish digest the sharp shells. In addition to frontal canine teeth, Atlantic wolffish also have flat teeth in the back of their mouth. They have several different kinds of teeth Their skin ranges from blue-grey to green and purple. Atlantic wolffish come in a variety of colours Their Pacific Ocean relative (the wolffish, Anarrhichthys ocellatus) is known as the wolf eel. These protruding teeth give them appearance of a wolf or other fearsome predator.Ītlantic wolffish are also called seawolves, ocean catfish, devil fish, sea cats, and woofs. They have a set of cone-shaped, fanglike teeth on both their top and bottom jaws. Atlantic wolffish get their name from their impressive teeth They are currently a species of concern due to overfishing and bycatch, however there is little data on their population as they live on the bottom of the sea bed. Their distinctive teeth, unusual adaptations for aquatic life, and role in the ocean ecosystem make them an important animal to study. Long, partially cylindrical bodies with tapered tails and large dorsal and ventral finsĪtlantic wolffish are a benthic species, meaning that their natural habitat is the bottom of oceans. They are known for their unusual teeth and breeding behaviours.Ītlantic Wolffish Facts Overview Habitat: Atlantic wolffish are a species of large, mostly solitary fish native to the North Atlantic Ocean.
