Chaenocephalus aceratus, the blackfin icefish, is a species of crocodile icefish known from around Bouvet Island and the northern Antarctic Peninsula where it occurs at depths of 5 to 770 metres (16 to 2,526 ft). This species grows to a length of 72 centimetres (28 in) TL. It is of minor importance to commercial fisheries. This species is the only known member of its genus.
Biology
The blackfin icefish is apparently unique among vertebrates in that it lacks both red blood cells and hemoglobin. Its only form of oxygen transport is dissolved oxygen in its blood plasma.
