Nothern wolffish

Anarhinchas minor

The northern wolffish (Anarhichas denticulatus), or rock turbot, is a large marine fish of the Anarhichadidae family. Other common names include the bull-headed catfish, blue catfish, broad-headed catfish, jelly wolffish, and the Arctic wolffish. Inuit in the Western Arctic (Bathurst Inlet) do not distinguish between the northern wolffish and the Bering wolffish (A. orientalis), calling both by the name akoak or akoaksaluk ("old woman fish").

This fish, sometimes considered "charmingly ugly", is found across the North Atlantic Ocean from north of Russia to the Scotian Shelf, off Nova Scotia. Its western Atlantic population declined dramatically during the 1980s, in part because it is often caught by fishers seeking other catch. The population was observed to decline by more than 90% from the late 1970s through the early 1990s.
