Elephants have massive ears to help regulate their body temperature. They have huge blood vessels in their ears. The blood vessels are large and quite visible on the backs of the elephant’s ears. The vessels allow for excellent blood circulation. As the blood flows through the ears, it cools down. The cooled blood then circulates through the rest of the elephant’s body. Elephants encourage blood circulation by flapping their ears like giant fans. Flapping their ears also helps cool down the front of their body as the flapping creates a slight breeze. Fapping ears keeps pesky insects at bay. too!
Do Big Ears Give Elephants Better Hearing?
Elephant ears are designed to keep the body cool. The ears’ large size also gives elephants remarkable hearing. Researchers think the large outer ear may help direct sounds to the inner ear, making it easier to hear. Having excellent hearing helps elephants better detect possible threats.
Big Ears are Great for Communication
Elephants are excellent communicators. They use vocalizations, vibrations, and body language to talk to each other. They move their ears to tell fellow animals about their intentions. Elephants have more facial neurons than any other land mammal in the world. The abundance of these neurons gives them remarkable control of their ears. They will flick their ears forward to show they are listening to something, and when elephants flare their ears. They may be excited or trying to fend off predators or challengers.
