Descripción breve
Claves de identificación | Morfología | Morfometría
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.
