EMPEROR PENGUIN
Aptenodytes forsteri
Of the 18 species of penguins on Earth, emperor penguins are the biggest. They stand around 1.2 metres tall and weigh 40 kilograms, but this weight fluctuates regularly throughout the year. These flightless birds utilise their fat stores to insulate themselves against the harsh conditions of Antarctic winter along with several layers of scalelike feathers, which can withstand gusts of up to 68 miles per hour before they’re ruffled and the wind cuts through the warm layer. Emperor penguins also huddle together in colonies to cut down heat loss by 50 per cent.
