FBname: Filetail catshark
Comments: Found on the outer continental shelf and upper slope.  Feeds on a variety of small fish (e.g. lanternfish) and invertebrates.  Oviparous.  Possesses an enlarged gill region which is an adaptation to areas with low dissolved oxygen levels.  Has a high concentration of squalene in its liver which affords it neutral buoyancy.  Regularly caught by bottom trawlers but not utilized at all.
