Endemic of Antarctica, Emperor penguins are the tallest of all species of penguins. They reach over one meter, weighing up to 45 kg (99 lb) and considered to be the only animal to inhabit the open ice of Antarctica during the winter, facing temperatures as cold as -60°C (-76°F) and blizzards of 200 km/h (124 mph). Excellent swimmers, they can dive deeper than any other bird – as deep as 565 m (1850 ft.) – and they can stay under for more than 20 minutes.
