Hygophum reinhardti (Lütken, 1892) .

Broadhead Lanternfish or Slender Lanternfish. To 6.4 cm (2.5 in) SL (Personal communication: Scripps Institution of Oceanography Fish Collection, La Jolla, California). Circumglobal; western Pacific Ocean north to Japan (Nakabo in Nakabo 2002); eastern Pacific Ocean from about 40°N (Bekker 1983) to Chile (Pequeño 1989). Reported from Gulf of Alaska (Wilimovsky 1954, 1958; Quast and Hall 1972) but documentation evidently lacking (Mecklenburg et al. 2002). Mesopelagic (Hulley and Paxton in Carpenter and De Angelis 2016); depth: surface to 3,346 m (10,974 ft) (min.: Personal communication: Scripps Institution of Oceanography Fish Collection, La Jolla, California; max.: Personal communication: Los Angeles County Museum of Natural History Fish Collection, Los Angeles, California). This maximum depth was based on the maximum depth fished by a midwater trawl and may represent a catch shallower than the maximum depth.
