Etymology: Dissostichus: Greek, disso = twice, one or other + Greek, stix, stichos =line, row (Ref. 45335); eleginoides: eleginoides deriving from the genus Eleginops for an assumed resemblance to that genus (Ref. 11892).
Environment: milieu / climate zone / depth range / distribution range
Ecologia

Southeast Pacific and Southwest Atlantic: southern Chile round the coast to Patagonia (Argentina) and the Falkland Islands. Southwest Pacific: Macquarie Island. Southern Ocean: South Georgia. Also known from sub-Antarctic islands and seamounts of the Indian sector.

Max length : 215 cm TL macho/indeterminado; (Ref. 2121); common length : 70.0 cm TL macho/indeterminado; (Ref. 2121); peso máx. publicado: 9.6 kg (Ref. 58336); idade máx. registrada: 31 anos (Ref. 87879)
Espinhos dorsais (total): 8 - 10; Raios dorsais (total): 28-30; Espinhos anais 0; Raios anais : 28 - 30; Vértebras: 53 - 54. Lateral line scales 88-104 (upper), 61-77 (lower).
At 12-15 cm TL, semi-pelagic juveniles become demersal at 150-400 m depth (Ref. 55957). Adults migrate to deeper habitats at depths greater than 1,000 m (Ref. 55957). Utilized as food fish (Ref. 4931).
May spawn for the first time from around 8-10 years of age (Ref. 71843).
