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
বাস্তুসংস্থান
সামুদ্রিক সমুদ্রবক্ষে ভাসমান (ব্যথিপেলাজিক); গভীরতার পরিসীমা 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).

Maturity: Lm ? range ? - ? cm
Max length : 44.3 cm TL পুরুষ/ লিঙ্গ অনিধর্ারিত ; (Ref. 124149); 33.6 cm TL (female); সবের্াচ্চ প্রকাশিত ওজন : 563.60 g (Ref. 124149)
পৃষ্ঠীয় কাঁটা (মোট ) : 7; পৃষ্ঠীয় নরম পাখনা দন্ড (মোট ) : 34; পায়ূর নরম পাখনা্তুন্ড: 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.
