Even in conditions dropping as low as -76 degreesFahrenheit, these impressive penguins spend their entire lives on the ice or inthe waters surrounding Antarctica. Thankfully, evolution has endowed them withfour layers of feathers to help keep them warm year round, with a waterproofcoat on the outermost layer. They also are able to maintain high amounts of fatto insulate their bodies from the harsh conditions. But that's not all. Almost every feature of the emperor penguin's build isadapted to help these fearless feathery creatures survive the Antarctic winter.Their small bills and flippers help conserve heat, while their nasal passagesare especially small to minimize the heat usually emitted through exhalation.And, thanks to closely situated arteries and veins, emperor penguins are able torecycle their own body heat, cooling blood to their extremities and warming itwhen it returns to the heart. Every winter (which begins in March[https://www.askqotd.com/the-winter-solstice/] at the South Pole), emperorpenguins travel up to 50 miles to find a suitable breeding ground and a mate.Males usually arrive first to set up shop (AKA get reading for their courtingritual), before then mating for the season. Most emperor penguins mate once aseason with a new mate, but some decide to couple up again the following winter(all in the chemistry, we suppose). Since there are no nesting supplies available on a frozen tundra, emperorpenguins incubate the eggs using their own body heat. The male penguins staywith the eggs throughout the winter, huddling in packs for warmth, while thefemales make the long trek back to the sea to feed. Come spring, the chickshatch and consume the mother's regurgitations, allowing the males to go off andfeed themselves. The next winter, the cycle begins again.Learn more about emperor penguins here[https://www.youtube.com/watch?v=A9mbCNs47FI].
