How do Elephants Communicate?

Elephants communicate through both sound and touch, among other things. But, did you know that they can also communicate via inaudible vibrations called "rumbles"?

Yes, elephants can pick up sounds that even we humans cannot hear by picking these up with their bones. These vibrations are usually in the infrasonic range of 30 Hertz.

Elephants don't just hear these frequencies in their bones, though; they can also produce them to communicate! In fact, elephant "rumbles" can travel just over 2km away!
