Since it's so cold here and the ice is a couple of miles deep, no plants can grow at the South Pole. We're also far away from the coast, so it's difficult for animals to get here.
McMurdo Station is on the coast, though and there are all kinds of animals there. The most notorious is the skua, a bird which is kind of like a sea gull. In the wild, they're known for stealing food from other birds. At McMurdo, they're known for stealing food from people! Everyone is warned not to carry food in the open, or a skua will swoop down and try to steal it!
