Highsnout Bigscale or Highsnout Ridgehead. To 10.9 cm ( 4.3 in ) SL ( Sinclair and Stabeno 2002 ). Subarctic North Pacific from Japan (Fujii in Masuda et al. 1984 ), and Sea of Okhotsk, to Bering Sea (about 56°N ), and Gulf of Alaska (Mecklenburg et al. 2002), to southern Baja California ( 25°30’N , 115°17’W ) (Personal communication: Scripps Institution of Oceanography Fish Collection, La Jolla, California); one record from off Michoacán ( 17°54.1’N , 103°23.8’W ), Mexico (Personal communication: Scripps Institution of Oceanography Fish Collection, La Jolla, California). Adults mesopelagic and bathypelagic; depths: 150– 2,287 m ( 492–7,501 ft ) (min.: Mecklenburg et al. 2002; max.: Personal communication: Los Angeles County Museum of Natural History Fish Collection, Los Angeles, California); juveniles as shallow as 30 m ( 98 ft ) (Personal communication: Russian Academy of Science Ichthyological Collecton at Saint Petersberg). A record of 4,393 m ( 16,200 ft ) (Personal communication: Scripps Institution of Oceanography Fish Collection, La Jolla, California) was based on the maximum depth fished by a midwater trawl and may represent a catch shallower than the maximum depth.
