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.

Wesley E. LeMasurier is an igneous petrologist/volcanologist who specializes in the study of Cenozoic volcanoes in the Marie Byrd Land region of Antarctica. He was responsible for geological research around many of Westarctica's volcanic mountains. Mount LeMasurier was named in his honor.

Dr. LeMasurier's work includes studying the origin and evolution of Cenozoic volcanic rocks, the nature of the tectonic environment of volcanism, and the volcanic record of glacial history. In 1990, after conducting a survey of Mount Berlin, he declared the volcano to be "potentially active." Later, in 1994, during field work around Mount Siple, Dr. LeMasurier knocked off a piece of rock from the mountain and sent it to Ruth Siple, the widow of Paul A. Siple, for whom the mountain was named.
