Highlight Hatchetfish. To 7 cm (2.8 in) SL (Aizawa in Nakabo 2002). Circumglobal; western Pacific Ocean north to Japan (Fujii in Masuda et al. 1984); British Columbia (Peden 1975) to Chile (Baird 1971). Depth: 156–2,300 m (492–7,544 ft) (min.: Personal communication: Los Angeles County Museum of Natural History Fish Collection, Los Angeles, California; max.: Porteiro et al. 2017). A record of 5,041 m (16,383 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.
