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
生态学

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.
東南太平洋與西南大西洋: 智利南部圓的岸邊到巴塔哥尼亞 (阿根廷) 與福克蘭群島。 西南太平洋: Macquarie 島。 南極海: 南喬治亞州。 也已知來自印度地區的接近南極的島嶼與海洋山脊。
Length at first maturity / 大小 / 重量 / 年龄
Maturity: Lm 49.0, range 38 - 60 cm
Max length : 215 cm TL 雄鱼/尚未辨别雌雄; (Ref. 2121); common length : 70.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 2121); 最大体重: 9.6 kg (Ref. 58336); 最大年龄: 31 年 (Ref. 87879)
背棘 (总数): 8 - 10; 背的软条 (总数): 28-30; 臀棘 0; 臀鳍软条: 28 - 30; 脊椎骨: 53 - 54. Lateral line scales 88-104 (upper), 61-77 (lower).
侧线鳞片 88-104(上面的),61-77.(低的)
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).
在 12-15 公分TL, 半大洋性稚鱼在 150-400 公尺深变成底栖.(参考文献 55957) 成鱼在深度大于 1,000 公尺回游到较深的栖息地。 (参考文献 55957) 作为食用鱼了。 (参考文献 4931)
