Entorno: milieu / zona climática / rango de profundidad / gama de distribución
Ecología
marino batipelágico; rango de profundidad 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).
Tamaño / Peso / Edad
Madurez: Lm ?  range ? - ? cm
Max length : 44.3 cm TL macho / no sexado; (Ref. 124149); 33.6 cm TL (female); peso máximo publicado: 563.60 g (Ref. 124149)
Espinas dorsales (total) : 7; Radios blandos dorsales (total) : 34; Radios blandos anales: 30. Gray with violet hue and lighter below with metallic luster. In alcohol, purplish gray or light brown dorsally (Ref. 11892).
Body shape (shape guide): fusiform / normal.
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.
