Found on soft, muddy bottoms; requires high salinity (at least 30 ppt) and low temperature (below 12°C), conditions usually found in deeper waters (Ref. 5951). Feeds chiefly on dead and dying fish of varying species by boring into the body and consuming viscera and musculature. Food includes marine invertebrates such as polychaete worms and crustaceans (shrimp, Pandalus borealis, an important food item) (Ref. 5951). Chiefly nocturnal.
