An elephant has an excellent sense of hearing, using its ears, trunk, and feet. Elephants can sense other elephants from several kilometers away through vibrations in the ground. Stomping their feet is one type of communication. Elephants will also trumpet and growl as in a greeting or warning.

Frequently fanning their ears helps an elephant cool down. Since the elephant has a large skin surface area to volume ratio, it is difficult to release body heat. The cool air produced by fanning also cools the many blood vessels close to the ears’ surface. This blood then circulates to help the elephant body cool to 10 degrees less. Skin on an elephant ear is thinner than most parts of its body.
