Short description Morphology | Morphometrics

Dorsal soft rays (total): 270. Dark purplish grey in color (Ref. 3973). Anal rays about 270 (Ref. 3973).

Found on the continental slope near the upper limit of abyssal zone (Ref. 6726). Epibenthic (Ref. 58426). Probably most common in 800 to 2,000 m (Ref. 5235). Do not tolerate higher water temperatures (Ref. 5951). Feeds mainly on Decapoda, Natantia, amphipods, but also fishes and cephalopods (Ref. 6726). Caught by bottom longline and baited fish trap (Ref. 85806).
