Benthopelagic; depth: to 380 m ( 1,246 ft ) and deeper, sometimes migrating to surface; juveniles mesopelagic ( Nakamura and Parin 1993 ). Originally described as a subspecies of Benthodesmus elongatus (Clarke, 1879) , this form was treated as a full species by Nakamura and Parin (1993) and recognized as such by Nelson et al. (2004); B. pacificus occurs in the North Pacific, whereas B. elongatus occurs in the Southern Hemisphere in the Indian, Pacific, and Atlantic Oceans. Records from British Columbia and Washington ( Peden and Hughes 1986 ) were reported as Benthodesmus tenuis (Günther, 1877) .
