Emperor penguin

The Emperor penguin is the world's largest species of penguin, and one of the world's largest birds.

Like all penguins, it is flightless but a good swimmer. It is confined to Antarctica, where its habitt is threatened by the melting of the ice cap, leading to fears that it will be extinct by 2100.

The eggs are generally hatched by the male rather than the female; he keeps them on the top of his feet for armth.
