The Bering wolffish is one of only five species in the wolffish family and is closely related to the similar-looking wolf eel. Unlike the wolf eel, the Bering wolffish have a distinct difference between the dorsal, anal, and caudal fins. This fish is also shorter and stockier than the slender wolf eel.
This wolffish has large crushing teeth for eating shelled animals like mussels, crab, and sea urchins. Despite their fearsome appearance, some SCUBA divers make it a habit of visiting wolffish. Wolffish tend to be less active as adults and will stay within the same area.
