Emperor penguins can dive deeper than any bird and stay underwater for up to 20 minutes at a time.
The male balances the egg on his feet and covers it with a feathered pouch to protect it.
During the months of babysitting the egg, the male does not eat anything.
After the female emperor penguin lays an egg, she goes off to search for food. It is the male that looks after the egg, keeping it warm till it hatches.
