Tamanho / Peso / Idade
Maturity: Lm ?  range ? - ? cm
Max length : 72.5 cm SL macho/indeterminado; (Ref. 6181)
Espinhos dorsais (total): 19 - 20; Raios dorsais (total): 15-17; Espinhos anais 2; Raios anais : 12 - 14; Vértebras: 34. 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.
