Dusky Hatchetfish . To 5.5 cm ( 2.2 in ) SL (Personal communication: Scripps Institution of Oceanography Fish Collection, La Jolla, California). Circumglobal ( Fricke et al. 2020 ); western Pacific Ocean north to Japan (Fujii in Masuda et al. 1984 ); at least Monterey Bay, central California ( Burton and Lea 2019 ) to Peru – Chile border ( Baird 1971 ). Depth: surface to 1,393 m ( 4,569 ft ) (min.: Personal communication: Scripps Institution of Oceanography Fish Collection, La Jolla, California; max.: Cruz-Acevedo et al. 2018 ). A record of 4,268 m ( 13,999 ft ) (Personal communication: Los Angeles County Museum of Natural History Fish Collection, Los Angeles, California) was based on the maximum depth fished by a midwater trawl and may represent a catch shallower than the maximum depth.
