Wolf Eel

The wolf eel is not a true eel, but part of the Anarhichadidae family of “wolf fishes”. This fish likes to live in rocky areas and is able to squeeze into small crevices due to its long, slender body. The wolf eel is gray, with many dark vertical bands and spots. It has an impressive appearance with strong jaws and sharp, spiky front teeth.

Wolf eels are attentive parents. Both males and females will wrap their bodies around the egg mass to keep it in place and protect it from predators. Only one wolf eel will leave the eggs to hunt at a time. A pair of wolf eels may remain together and mate for life.

The wolf eel eats hard-shelled animals such as snails, clams, crabs, and sea urchins.

The wolf eel can reach nearly 8 feet long.

A Note From the Caretaker

Wolf eels can be very territorial and have been known to bite at sharks to keep them out of their caves.
