Emperor Penguinエンペラーペンギン
Aptenodytes forsteriEN— Endangered
The emperor penguin is the tallest and heaviest of all living penguin species, breeding in the depths of the Antarctic winter on sea ice. Males alone incubate the single egg for about two months without eating, huddling together in temperatures well below freezing while females forage at sea.
