Antarctica is too cold to support any animal life. Nothing grows there and there is no food chain.

However, the Southern Ocean that surrounds the continent is the richest, most protein-productive water on earth. As well, these waters have the shortest food chain on earth. Krill form the base of the food chain and they feed on phytoplankton. Other animals consume the krill, including penguins, seals, whales and other sea birds and sea animals.
