Slim Lightfish . To 14 cm ( 5.5 in ) SL ( Balanov et al. 2009 ). Western Pacific Ocean north to Japan (Fujii in Masuda et al. 1984 ) and southern Kuril Islands ( Parin et al. 1995 ); near Vancouver Island, British Columbia ( Peden and Hughes 1986 ) to southern Baja California ( Berry and Perkins 1966 ). Mesopelagic (Fujii in Masuda et al. 1984 ); depth: 100–1,948 m ( 328–6,389 ft ) ( Kamikawa 2017 ). A record of a possible maximum depth of 5,488 m ( 18,000 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.
