The Emperor Penguin is a penguin that lives in Antarctica. It is the tallest and heaviest of all penguin species. Emperor Penguins are black and white like all penguins but the sides of their neck are golden. Emperors live in the coldest climate on earth. They breed at the beginning of the Antarctic winter (March and April), on the ice all around the Antarctic continent. The shape of their body helps them to survive. They have short wings that help them dive up to 900 feet to catch larger fish. They can swim up to 12 miles per hour for a short time, which lets them escape from their main enemy, the Leopard Seal. They can stay warm because they have a thick layer of blubber. In addition, the layer of soft feathers trap air that keeps the body heat in and cold air and water out.
