The '''[[Antarctic toothfish]]''' is a species of cod icefish native to the [[Southern Ocean]]. It is often mistakenly referred to as an [[Antarctica|Antarctic]] cod, consistent with the misnaming of other notothenioid Antarctic fish as rock cods. However, notothenioid fishes are unrelated to cods, which are in another taxonomic order, the Gadiformes. The generic name Dissostichus is from the Greek ''dissos'' (twofold) and ''stichu''s (line) and refers to the presence of two long lateral lines, which are very important to the species’ ecology. The common name "toothfish" refers to the presence of biserial dentition in the upper jaw, thought to give it a shark-like appearance.
'''[[Ernest Shackleton]]''' was a polar explorer who led three British expeditions to the [[Antarctica|Antarctic]], and one of the principal figures of the period known as the Heroic Age of Antarctic Exploration.


The habitat of the Antarctic toothfish is in subzero degree water below latitude 60°S.
After the race to the [[South Pole]] ended in December 1911 with [[Roald Amundsen]]'s conquest, Shackleton turned his attention to the crossing of [[Antarctica]] from sea to sea, via the pole. To this end he made preparations for what became the Imperial Trans-Antarctic Expedition, 1914–17. Disaster struck this expedition when its ship, ''[[Endurance]]'', became trapped in [[pack ice]] and was slowly crushed before the shore parties could be landed. The crew escaped by camping on the sea ice until it disintegrated, then by launching the lifeboats to reach Elephant Island and ultimately the inhabited island of South Georgia, a stormy ocean voyage of 720 nautical miles and Shackleton's most famous exploit.
