How do whales talk to each other?
Deep in the ocean, where sunlight fades to blue-black and the nearest whale might be miles away, how do whales have a conversation? They can't exactly swim over and tap a friend on the shoulder. So they do something that sounds like magic: they sing through the water itself.
Water is a whale's telephone network. When a whale makes a sound — a rumble, a click, a long musical note — that sound travels as a pressure wave through the ocean, the same way ripples spread when you drop a stone in a pond. Except sound moves through water almost five times faster than through air, so a whale's call can zoom across miles of ocean in minutes.
