The '''[[Antarctic petrel]]''' is a boldly marked dark brown and white petrel, found in [[Antarctica]], most commonly in the [[Ross Sea|Ross]] and [[Weddell Sea]]s. They eat [[Antarctic krill]], fish, and small squid. They feed while swimming but can dive from both the surface and the air.
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 Antarctic petrel is the only known species in the genus ''Thalassoica'', and is a member of the family Procellariidae, and the Procellariiformes order. Also, this petrel along with the [[snow petrel]], the [[Cape petrel]], both giant petrels, and the two species in the Fulmarus family, are considered to be a separate group from the other Procellariidae members. They share certain identifying features. First, they have nasal passages that attach to the upper bill called naricorns. Although the nostrils on the petrels are on the top of the upper bill. The bills of Procellariiformes are also unique in that they are split into between seven and nine horny plates.
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.

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.
