Southern Ocean: South Orkney and South Shetland Islands, tip of Antarctic Peninsula north of 65°S and the Antarctic continental shelf.
Length at first maturity / Size / Weight / Age
Maturity: Lm 10.0  range ? - ? cm
Max length : 15.5 cm TL male/unsexed; (Ref. 124149); 15.3 cm TL (female); max. published weight: 17.00 g (Ref. 124149); max. published weight: 17.00 g
Adults spawn apparently during autumn and early winter. Hatching probably occurs in spring and size at hatching at about 12 mm TL. Main food items are polychaetes and benthic crustacean (Ref. 5192). Larval pelagic phase is short (Ref. 41551).
