Weddell seals spend their whole lives in Antarctic waters, even when the surface of the ocean freezes solid. Seals are mammals, like us, they need to breathe air – although they can hold their breath underwater for more than an hour! To survive, they must maintain breathing holes in the ice, using their canine-like teeth to scour away the ice as it refreezes.	Adelie penguins are Antarctica's most studied living organism. They don't march 90km inland to like their 'movie star' emperor penguin relatives. But that doesn't mean they have it easy when it comes to breeding. They build their nests on land close to the seashore, using pebbles that they collect from the rocky slopes around them.
