Blunt scalyhead

Biology
Most common in shallower waters of the continental shelf, especially on banks less than 250 m deep in areas where local upwellings increase food supply (Ref. 6390). Juveniles are found near the surface, often in association with Antarctic krill (Euphausia superba) swarms. Feed on salps, nudibranchs, amphipods, copepods, polychaetes, krill, crustaceans, chaetognaths, and fish
