Emperor penguin (Aptenodytes forsteri)
The largest of modern penguins. It is tall up to 122 cm and the body weight reaches up to 45 kg. In the past there lived penguins, twice larger than the recent Emperor penguin. The female lays a single egg once every 2-3 years. It weighs about 500 grams. The egg is incubating in a skin fold between the legs by both parents. In search of food the adults reach record depths in the icy ocean waters — up to 200 metres.
