Southern Elephant Seals

Elephant Seals can tip the scale at a hefty 7,900 pound (3,600 kilos) and measure up to 15 feet (4.5 meters). Elephant Seal These are the big daddies of the Antarctic beach. Elephant Seals can tip the scale at a hefty 7,900 pound (3,600 kilos) and measure up to 15 feet (4.5 meters). They commonly are found throughout the sub-Antarctic islands, although some colonies are located near the continent. Being larger in this specie, males dominate the breeding process. They, first, battle with other males to establish territory on the beach. To the victor goes the spoils; this includes harems which can include up to 50 females. Breeding colonies are terribly cramped for space. These multi-ton beasts lie next to and on top of each other. Often, pups are crushed under the weight of adult seals. In order to satisfy their huge appetites, Elephant Seals dive deep into the ocean and feed on various forms of fish and squid.

Canada travel guide - Wikitravel

Canada travel guide - Wikitravel : Canada is a land of vast distances and rich natural beauty. Economically and technologically, and in many other ways she closely resembles her neighbour to the south, the United States, although there are significant differences between the two countries. Canada is perfectly happy with its British heritage and many Canadians are proud of this. Canada has historically been built and influenced by immigrants from two European nations, Britain and France. This dual nature is very different than in the United States, and in some parts of Canada, particularly Quebec and parts of New Brunswick, Canadians primarily speak French. Canada became a self-governing dominion in 1867 by an act of the British parliament, and is still a proud member of the Commonwealth of Nations.

Weddell Seals Weddells can dive in excess of 1,000 feet (300 meters) in search of food

One of the more commonly sighted seals, Weddells often are found in groups. Some of these groups contain several hundred seals, although this typically occurs during their breeding season (September to November). During this time, males engage in numerous territorial battles. Unlike other species, these seals prefer to lie on snow and ice even when open land or rock is available. This trait, along with their desire to avoid Orcas, is one of the primary reasons Weddells are found on inland fast ice around the continent. During the winter months, Weddells must maintain diving/breathing holes in the ice in order to feed. Feeding primarily on fish, Weddells can dive in excess of 1,000 feet (300 meters) in search of food. To make these long dives possible, they carry five time the amount of oxygen in their blood as human do. To get the most from this, Weddells slow their heart rate and limit blood circulation to vital organs such as the brain, kidneys, and liver.
