Pete the penguin, a star of SeaWorld, waddled down the aisle of a trans-American Southwest Airlines flight from San Francisco to San Diego. The South American Magellan Penguin had been appearing at a national science convention and was returning home. His SeaWorld keepers gave a lecture to passengers over the in-flight intercom as the bird ambled between their seats. Videos of his antics have begun to appear on YouTube. Magellanic Penguins take their name from the Magellan Strait, in Chile, where they originate from and live to between 25 and 30 years old. (March 22, 2011)
