Elephants May Talk Via Vibrations

A researcher from California went to Namibia, Africa, last month to check on the vibes elephants put out and pick up. She theorizes that by making the ground rumble, the 6-ton (5,400-kilogram) animals are able to communicate over distances upwards of 20 miles (32 kilometers).

Such signals could warn other elephants of predators, help a lonely elephant find a mate, or direct them towards food and water.
