Max length : 38.5 cm TL macho / no sexado; (Ref. 124149); 31.4 cm TL (female); peso máximo publicado: 86.20 g (Ref. 124149); peso máximo publicado: 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).
