Brotulataenia nielseni Cohen, 1974.
To 31.2 cm (12.3 in) SL (Machida et al. 1997). Indo-Pacific; western Pacific Ocean north to Miyagi Prefecture, Japan (Ohashi et al. 2012); northern Baja California (32°02’N, 117°48’W) (Personal communication: Los Angeles County Museum of Natural History Fish Collection, Los Angeles, California) to south of equator (14°46’S, 93°38’W) (Cohen 1974). Pelagic and perhaps benthopelagic (Nielsen and Cohen in Nielsen et al. 1999); depth: taken in nets fished between surface and 300 m (984 ft) to 1,200 m (3,936 ft) (Cohen 1974). A record of 940 m (3,083 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.
