What do African Elephants use their big ears for?
African elephants use their big ears for a variety of purposes. They help them hear sounds from far away and they use them to communicate, sending different messages depending on how they move their ears. One of the most important uses of an elephant’s big ears, however, is for air conditioning.
Many of the places where elephants live get very hot. Their large ears have blood vessels running through them. As the elephant waves its ears this blood is cooled down and helps keep the whole animal cool.
