The '''[[Beardmore Glacier]]''' in [[Antarctica]] is one of the largest valley [[glacier]]s in the world, being 200 km (125 mi) long and having a width of 40 km (25 mi). It descends about 2,200 m (7,200 ft) from the Antarctic Plateau to the [[Ross Ice Shelf]] and is bordered by the Commonwealth Range of the [[Queen Maud Mountains]] on the eastern side and the Queen Alexandra Range of the Central [[Transantarctic Mountains]].
The '''[[bald notothen]]''' is a species of cod icefish native to the [[Southern Ocean]] where it is found in the [[Weddell Sea]], the [[Ross Sea]], the Davis Sea, in Vincennes Bay, and around the Budd Coast, the [[Antarctic Peninsula]], South Orkneys and South Shetland Islands.


The glacier is one of the main passages through the Transantarctic Mountains to the great polar plateau beyond, and was one of the early routes to the [[South Pole]] despite its steep upward incline. The glacier was discovered and climbed by [[Ernest Shackleton]] during his Nimrod Expedition of 1908. Although Shackleton turned back before reaching the [[South Pole]], he established the first proven route towards the pole and, in doing so, became the first person to set foot upon the polar plateau.
It can be found at depths of from the surface to 550 meters (1,800 ft) though it is much rarer below 30 meters (98 ft). This species is often found along the under surfaces of [[ice]] foraging for prey such as sympagic copepods and [[krill]]. In turn, it is known to be preyed upon by the [[ploughfish]] and the [[Antarctic toothfish]]. Antifreeze proteins in its blood prevent it freezing in the subzero water temperatures of [[Antarctica]].
