Maturité: Lm ?  range ? - ? cm
Max length : 100.0 cm TL mâle / non sexé; (Ref. 27000)
Rayons mous dorsaux (Total) : 270. Dark purplish grey in color (Ref. 3973). Anal rays about 270 (Ref. 3973).
Body shape (shape guide): eel-like.
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).
