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).
Environment: milieu / climate zone / depth range / distribution range
生態學
海洋 深海區的; 深度上下限 400 - 1500 m (Ref. 127764). 深水域
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).
南極海: Scotia 海洋，威德爾海的島, Prydz 海灣與羅斯海洋。 一個個別的亞種可能是出現在羅斯海洋族群, 但是這需要更多的證據.(參考文獻 5179) 記錄來自奧拉夫 Prydz 海灣， Mackenzie 海洋，南極圈的印度地區了。 (參考文獻 44178)
大小 / 重量 / 年齡
Maturity: Lm ? range ? - ? cm
Max length : 44.3 cm TL 雄魚/尚未辨別雌雄; (Ref. 124149); 33.6 cm TL (female); 最大體重: 563.60 g (Ref. 124149)
背棘 (總數) : 7; 背的軟條 (總數) : 34; 臀鰭軟條: 30. Gray with violet hue and lighter below with metallic luster. In alcohol, purplish gray or light brown dorsally (Ref. 11892).
灰色的有紫羅蘭色的色與腹面顏色較淡具有金屬的光彩。 當保存在酒精中時, 背面的帶紫色的灰色或淡褐色.(參考文獻 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.
吃浮游動物。 在脂肪組織的細胞的脂質的儲藏以及骨骼的被縮小的石灰化提供浮力給這種。
