Emperor Penguins of Antarctica

Emperor Penguins are the largest penguin species. They stand about 115 cm tall and can live to more than 40 years. Depending on the stage of their breeding cycle they weigh from 23 to 40 kilograms. Emperor penguins breed in colonies scattered around the antarctic continent. Colonies range in size from a few hundred to over 20,000 pairs. All but two colonies are situated on the fast-ice that is locked between islands or grounded icebergs. 
They are the only animals that breed during the antarctic winter. Though are not very territorial emperor penguins huddle tightly together and share body warmth during the fierce winter storms. As there are no nesting materials, emperor penguins incubate the single egg on their feet. In relation to the body size of the female the egg is rather small and it weighs only about 450 gram.
