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).

Ökologie
seewasser; ozeanodrom (Ref. 51243); tiefenbereich 0 - 2144 m (Ref. 127764), usually 70 - 1500 m (Ref. 2121). Temperate; 33°S - 66°S, 77°W - 180°E (Ref. 54228)
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.
Length at first maturity / Size / Gewicht / Alter
Maturity: Lm 49.0, range 38 - 60 cm
Max length : 215 cm TL Männchen/unbestimmt; (Ref. 2121); common length : 70.0 cm TL Männchen/unbestimmt; (Ref. 2121); max. veröff. Gewicht: 9.6 kg (Ref. 58336); max. veröff. Alter: 31 Jahre (Ref. 87879)
Rückenflossenstacheln (insgesamt) : 8 - 10; Rückenflossenweichstrahlen (insgesamt) : 28 - 30; Afterflossenstacheln: 0; Afterflossenweichstrahlen: 28 - 30; Wirbelzahl: 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).
