بوم شناسي
دريايي ناحیه ای از منطقه اقیانوسی با عمق بین 1000 تا 4000 متر. موجوداتی که در آبهای آزاد بین اعماق 1000 تا 4000 متر زندگی و تغذیه می کنند; تغييرات عمق 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 / Weight / سن
Maturity: Lm ? range ? - ? cm
Max length : 44.3 cm TL جنس نر / بدون خواص جنسي; (Ref. 124149); 33.6 cm TL (female); بيشينه وزن گزارش شده: 563.60 g (Ref. 124149)
خارهاي باله پشتي (کل): 7; شعاع نرم باله پشتي (کل): 34; شعاع نرم باله مخرجي: 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.
