Etymology: Aethotaxis: Greek, aethia, = unusual + Greek, taxis = disposition (Ref. 45335); mitopteryx: The specific name is derived from the Greek word mitos (thread or string) and pteryx (wing), referring to the filamentous nature of the first dorsal spines and pelvic rays (Ref. 11892).

生態学
海 深海浮遊性; 深さの範囲 400 - 1500 m (Ref. 127764). Deep-water
Southern Ocean: islands of the Scotia Sea, Weddell Sea, Prydz Bay and the Ross Sea. A separate subspecies may be present in the Ross Sea population, but this needs more evidence (Ref. 5179). Reported from Olaf Prydz Bay, Mackenzie Sea, Indian sector of the Antarctic (Ref. 44178).
サイズ / 重さ / 年齢
Maturity: Lm ?  range ? - ? cm
Max length : 44.3 cm TL オス/雌雄の選別がない; (Ref. 124149); 33.6 cm TL (female); 最大公表体重: 563.60 g (Ref. 124149)
背面の脊椎 (合計) : 7; 背鰭 (合計) : 34; 臀鰭: 30. Gray with violet hue and lighter below with metallic luster. In alcohol, purplish gray or light brown dorsally (Ref. 11892).
Feeds on zooplankton. The storage of lipids in cells of adipose tissue as well as the reduced calcification of the skeleton provide buoyancy to this species.
