Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; depth range 5 - 400 m. Polar; 60°S - 69°S
Southern Ocean: South Orkney, South Shetland, Elephant Islands and tip of Antarctic Peninsula to 65°S.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 42.0 cm SL male/unsexed; (Ref. 5192)
Yolk larvae (2.3-3.2 cm TL) found from late October to early December; small juveniles from mid-January to mid-March, thus hatching may occur in late winter. Feeds on fish (Ref. 5192).
