The Antarctic toothfish is a species of cod icefish native to the Southern Ocean. Over the continental shelf, Antarctic toothfish feed on shrimp and small fish, principally another neutrally buoyant nototheniid, the Antarctic silverfish. This loosely schooling species is also a major prey of Adélie and emperor penguins, Weddell seals, and Antarctic minke whales. The common name "toothfish" refers to the presence of biserial dentition in the upper jaw, thought to give it a shark-like appearance.

The habitat of the Antarctic toothfish is in subzero degree water below latitude 60°S.
