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 '''[[southern elephant seal]]''' is one of the two species of elephant seals. It is the largest member of the clade Pinnipedia and the order Carnivora, as well as the largest marine mammal that is not a cetacean. It gets its name from its massive size and the large proboscis of the adult male, which is used to produce very loud roars, especially during the breeding season.


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]].

The southern elephant seal is one of the two species of elephant seals. It is the largest member of the clade Pinnipedia and the order Carnivora, as well as the largest marine mammal that is not a cetacean. It gets its name from its massive size and the large proboscis of the adult male, which is used to produce very loud roars, especially during the breeding season.

The world population was estimated at 650,000 animals in the mid-1990s, and was estimated in 2005 at between 664,000 and 740,000 animals. Studies have shown the existence of three geographic subpopulations, one in each of the three oceans. Tracking studies have indicated the routes traveled by elephant seals, demonstrating their main feeding area is at the edge of the Antarctic continent. While elephant seals may come ashore in Antarctica occasionally to rest or to mate, they gather to breed in subantarctic locations.
