Morphology | Morphometrics
Dorsal
spines
(total): 0;

spines: 0;
Anal
soft rays: 18 - 21. Dark brownish to blackish in color; paler below with no silvery scales; when specimen is without scales, an indistinct blackish anal spot of the peritoneum showing through the skin may be observed (Ref. 6602).
Larvae and juveniles pseudoceanic in midwater; adults taken by both bottom and pelagic trawls in about 600-800 m. Sub-adults and adults migrate to the Southern Ocean (to 60°S) to feed; on euphausiids, hyperiids, and other crustaceans as well as on small fishes, like myctophids; juveniles take small zooplankton, especially copepods.
