World's longest penguin dive, of more than half an hour, is recorded

Record-breaking dive in Antarctic waters emerges after scientists accidentally tagged wrong emperor penguins

Scientists in Antarctica have recorded the world's longest penguin dive, an astounding 32.2 minutes under the water; a full five minutes longer than the previous record.

Emperor penguins, which live only in Antartica, are the tallest and heaviest penguins in the world, and have the best diving ability. They can dive as much as 500 metres down in some of the world's harshest and coldest seas.
