Festive Lanternfish . To 15.7 cm ( 6.2 in ) (Personal communication: Scripps Institution of Oceanography Fish Collection, La Jolla, California). Circumglobal; western Pacific Ocean north to Japan ; in eastern Pacific Ocean as far northward as central California ( 35°58’N , 122°32’W ) (Personal communication: Scripps Institution of Oceanography Fish Collection, La Jolla, California). Mesopelagic; depth: 0–1,800 m ( 5,904 ft ) ( Porteiro et al. 2017 ). A record of 3,600 m ( 11,808 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. The eastern Pacific form could be L. festivus , Lampanyctus tenuiformis (Brauer, 1906) or an unrecognized species (Benjamin Frable).
