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).

生态学
海洋 深海区的; 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)

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.
吃浮游动物。 在脂肪组织的细胞的脂质的储藏以及骨骼的被缩小的石灰化提供浮力给这种。
