Highighted items on the list are where Anarhichas denticulatus may be found.
Remarks Inhabits offshore waters in midwater; adults also near bottom from 60-970 m, mainly 100-900 m (Ref. 4694). Epibenthic (Ref. 58426). Feeds on sea gooseberries, medusas, small fishes, also echinoderms, crustaceans and mollusks (not so hard-shelled) (Ref. 4694). Preyed upon by Sebastes marinus, Greenland shark (Somniosus microcephalus) and cod. Parasite of the species is known to be a copepod, Sphyrion lumpi (Ref. 5951).

Association remarks More than 100 young northern wolffishes were caught on August 11, 1980 at depths of 0-50 m, water temperature 12.4°, SE of the Great Newfoundland shoal; no other single young individual was found over a distance of 60-80 miles from this station. Morphometric changes in body shape from juvenile to adult point to its ecology: the young are pelagic (occupying the epipelagic zone of the open parts of the N. Atlantic and the neritic zone of shelves) and the adults have a benthic mode of life (Ref. 43800).
