Environment: milieu / climate zone / depth range / distribution range
Ecology
Marine; demersal; depth range 0 - 550 m. Polar; 61°S - 78°S
Southern Ocean: Antarctic Peninsula, South Shetland Islands and the Antarctic continental shelf. Probably circum-Antarctic, but no records yet from West Antarctica.
Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 38.5 cm TL male/unsexed; (Ref. 124149); 31.4 cm TL (female); max. published weight: 86.20 g (Ref. 124149); max. published weight: 86.20 g
Adults spawn during September in Adélie Land. Hatching probably occurs in spring (mid-November) and pelagic development probably ends in autumn (February and March). Food items: fishes, amphipods, fish eggs and polychaetes (Ref. 5192). Larval pelagic phase is short (Ref. 41551).

Estimates based on models
Preferred temperature (Ref.
123201): -1.8 - 0.4, mean -1.2 °C (based on 344 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00141 (0.00083 - 0.00240), b=3.46 (3.31 - 3.61), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trophic level (Ref.
69278): 4.2 ±0.73 se; based on food items.
Resilience (Ref.
120179): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming Fec < 10,000).
Fishing Vulnerability (Ref.
