Adults uniformly blackish; fins of juveniles with white margins (Ref. 6577).
Found on the outermost continental shelves and upper slopes, mostly below 275 m (Ref. 247). Epibenthic-pelagic (Ref. 58426). At high latitudes, may move up to the surface especially during the winter (Ref. 247). Bottom water temp. Are from 3.5 to 4.5°C, but sometimes down to 1°C. Segregation by sex and size as well as by movement into shallower water and by increase in school size is sometimes seen. Feeds on crustaceans, cephalopods, jellyfish and small fishes. Ovoviviparous (Ref. 205), with at least 14 pups in a litter (Ref. 247). Has luminescent organs in skin. May reach 107 cm.
