This isn't fantasy, it's real. And it isn't magic, just marvelous. It is a rare dolphin behavior, and we first saw it in the play of two baby dolphins. It gives us a little more insight into the superb level of control dolphins can exercise on their water environment, and underscores the fact that we can still discover things about dolphins by simply watching them.
