Most of the body is naked except for the wedge-shaped stripe of squamation extending forward from the caudal peduncle along the horizontal part of the lower lateral line and a few scales along the posterior part of the upper lateral line. Pyloric caeca 8 to 10. Pelvic fins entirely absent at over 25 cm SL. Body color is grayish or brownish with metallic tint; fins blackish or gray.
Probably schooling, migrates to midwater at night. Feeds on fishes (myctophids, Maurolicus, eels, macrourids, carangids, emmelichthyids, etc.), prawn and squid; large prey items are swallowed in parts (Ref. 6202). Matures at about 25 cm standard length. No special fishery but appears as a bycatch of deep-water prawn trawl fishery in New South Wales, Australia.
