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 penguin|Adélie]] and [[emperor penguin|emperor penguins]], [[Weddell seal|Weddell seals]], and Antarctic [[minke whale|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.

Quin Blackburn was a geologist on the First and Second Byrd Expeditions and leader of the geologic party that explored the Transantarctic Mountains. Blackburn served as a geologist and seaman—before—the mast on the First Byrd Expedition (1928-1930). During this expedition, Blackburn and 41 other explorers were forced to winter over in the Little America base due to their ship being stuck in the pack ice.
