Answer 10: One way in which emperor and king penguins are similar is that they both keep their eggs warm on their feet under a pouch of loose skin during breeding. However, emperor penguins breed in colder climates, such as Antarctica, while king penguins choose beaches without snow or ice. Additionally, emperor penguins are the biggest of all penguins and have the deepest dive of all birds, while king penguins have distinctive coloring with orange highlights on their head, beak, neck, and upper breast.
