Why Elephants Have Big Ears

Here is the main reason why elephants have large ears: Elephants typically live in very hot, dry climates. Elephants cannot sweat as humans do. So, elephants use their ears to regulate their body temperature.
Why do elephants flap their ears? Elephants use their ears like giant fans to help create breezes.
As elephants flap their ears back and forth, they create a light breeze to cool down faster.
