Atlantic Wolffish (Anarhichas lupus)

The Atlantic Wolffish or Anarhichas lupus is a rather odd looking saltwater fish that spends most of its time on the bottom floor of the ocean. They resemble a Blenny in appearance, but are much larger, growing to about 5' (150cm) in length and weighing in at 40lbs (18kg). You can check out some awesome footage of the Atlantic Wolffish in the video below.


This species of Wolffish goes by several different names throughout the world including the Atlantic Catfish, Seawolf, Devil Fish, Ocean Catfish, Wolf Eel and the Sea Cat. They are found in the cold waters of the Atlantic Ocean with a temperature range of 34-37°F (1-2°C). Like some other species of fish, they have a natural antifreeze in their blood that allows them to survive in such frigid conditions!

The Atlantic Wolffish has a serious set of chompers! They have 4-6 fang-like teeth in both their upper and lower jaws as well as a set of conical teeth. Behind that, they have a row of crushing teeth and four pairs of molars! Their throat is also scattered with serrated teeth. They use these extensive sets of teeth to crush anything with a shell and turn it into a tasty meal!

Wolf Eel (Anarrhichthys ocellatus)

The Wolf Eel or Anarrhichthys ocellatus has a human-like face with powerful jaws that it uses to crush its prey. These saltwater fish are normally found in the northern Pacific Ocean around rocks or reefs. They will often make their homes in a crevice, cave or a pile of rocks. This species is not a true Eel, because it has pectoral fins and is referred to as a Wolf Fish. It is an impressive specimen growing to over 6' long, and weighing in at 40lbs! Wolf Eels tend to eat clams, small fish, crustaceans, sea urchins and mussels. These fish are edible and are sometimes called Ocean Catfish when sold. You can watch some amazing underwater footage of the Wolf Eel in the video below...

When reproducing the male and female will wrap themselves around each other to protect their eggs for a period of several months. It is thought that some males and females only have one partner for their entire lives. They normally reach sexual maturity at about 7 years old.
