Ah yes the Emperor penguins. They may walk funny on land but at sea they can dive up to 1,850 feet (565 meters) deeper than any other bird, and stay under for more than 20 minutes. They are the largest of their species standing about 4 feet (1.2 meters) tall. The males keep their soon-to-be chick's eggs warm by balancing the eggs on their feet while Mom is on a food feast some 50 miles (80 ks) away. She must journey this far to open water.
