Biggest Animal Headlines of the Year

From Knut's death to the Bronx Zoo cobra, animal news went wild this year

HAPPY FEET

This young Emporer penguin's saga began in June, when he was found disoriented on a beach in New Zealand, nearly 2,000 miles from his home in Antarctica. After recuperating for two months at the Wellington Zoo, Happy Feet was released into the Southern Ocean. What has happened since is unknown; the bird's satellite tracker stopped transmitting in September.
