Have you ever noticed how big an elephant’s ears are? They’re like giant flaps! Elephants’ big floppy ears usually measure about 22 square feet in size. – Wow! Although you might think they use these giant ears for better hearing, elephants actually mostly use their big ears for cooling down when it’s hot!
Because elephants are so big and generally live in hot places like Africa or India, they need a little extra help when it comes to cooling off. Elephant ears are full of veins, the little passageways in the body that are responsible for moving blood around. By flapping their wet ears, the many veins in their ears are cooled, and so is the blood inside those veins! The cooled blood then travels all around the elephant, and can help lower the elephant’s body temperature by as much as almost 10 degrees Fahrenheit! That might not sound like a lot, but when it comes to body temperature it’s actually a pretty COOL amount!
