I was amazed at this fish caught the other day by Philip Torrey. It turns out to be a wolffish.

According to Wikipedia, a wolffish is also known as the seawolf, Atlantic catfish, ocean catfish, devil fish, wolf eel (the common name for its Pacific relative), woof or sea cat, and is a marine fish of the wolffish family Anarhichadidae

The Atlantic wolffish's distinguishing feature, from which it gets its common name, is its extensive teeth structure. Both the lower and upper jaws are armed with four to six fang-like, strong, conical teeth. Behind the conical teeth in the upper jaw, there are three rows of crushing teeth. The central row has four pairs of molars and the outer rows house blunted conical teeth. The lower jaw has two rows of molars behind the primary conical teeth. The wolffish's throat is also scattered with serrated teeth.
