The Northern wolffish (Anarhichas denticulatus) is a saltwater fish of the family Anarhichadidae that grows up to 180 cm.
Description
The northern or blue wolffish is a large, eel-like wolffish of the family Anarhichadidae reaching about 1.8 metres. Unlike its relatives this species has a strikingly jelly-like, flabby and blue-black body; the head bears strong jaw teeth, though less massive than in the Atlantic wolffish. The species lives on and above sand and mud bottoms in the cold, deep water of the northern Atlantic on both sides. Unlike the shellfish-crushing wolffishes the northern wolffish eats mainly soft prey such as jellyfish, comb jellies and sea urchins. It grows slowly and lays large eggs in nests on the bottom, which makes it sensitive to deep-sea fishing; in Canada it is a protected species.
