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
экология
морской батипелагический; пределы глубины 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).
Size / Вес / Возраст
Maturity: Lm ?  range ? - ? cm
Max length : 44.3 cm TL самец/пол неопределен; (Ref. 124149); 33.6 cm TL (female); наибольший вес (опубликованные данные): 563.60 g (Ref. 124149)
колючие лучи спинного плавника (общее число) : 7; членистые (мягкие) лучи спинного плавника (общее число) : 34; членистые (мягкие) лучи анального плавника: 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.
