Why do Whales Sing?

TED-Ed, Stephanie Sardelis

The ocean is a vast, open space, so to communicate underwater, it's best that your message travels far. Sound travels four times faster in water than in air, so many animals use this to their advantage. The whale is particularly famous for its melodious songs that echo in a hauntingly beautiful manner. But the singing may serve as more than a recreational pastime and, perhaps, serve as a way to communicate with other whales many miles away.
