Stylephorus chordatus Shaw, 1791 .

Thread-tail or Tube-eye. To 32 cm (12.6 in) SL (Olney and Hartel in Carpenter and De Angelis 2016). Circumglobal; Yaquina Head, Oregon (44°45’N) (NWFSC-FRAM) to well offshore San Diego (32°N, 124°W) (Personal communication: Scripps Institution of Oceanography Fish Collection, La Jolla, California). Larvae of this species have been reported off Colombia (Beltrán-León and Rios Herrera 2000). Mesopelagic and bathypelagic (Olney and Hartel in Carpenter and De Angelis 2016); depth: surface (nightlight; Personal communication: Scripps Institution of Oceanography Fish Collection, La Jolla, California) to perhaps 5,041 m (16,534 ft) (Personal communication: Scripps Institution of Oceanography Fish Collection, La Jolla, California). The deepest record was based on the maximum depth fished by a midwater trawl and may represent a catch shallower than the maximum depth.
