The South Georgia icefish is a dark greyish-green species with blackish first dorsal and pelvic fins. The pelvic fins have white outer borders. This species grows to a length of 60 centimetres (24 in) TL; a more common length is 50 centimetres. It is thought to mature at 42.5 cm. The maximum published weight of this species is 2.1 kg (4.6 lbs). Adults of this species feed mainly on krill (mostly Antarctic krill) and fish (mainly channichthyids and nototheniids) .
