Question: How can a elephant can communicate with others?

Ellen Williams answered on 13 Mar 2017:

Elephants communicate through infrasound. These are relatively low frequency noises and it is believed as humans we only hear about 10% of their conversations. Occasionally you hear elephants bellowing or rumbling. The low frequency infrasound carries over many miles so allows them to locate others in the wild. They also communicate a lot through touch – they will use their trunks to touch other elephants, and other physical actions such as ear flapping, staring, etc.
