Hurricane Irma has created a phenomenon that is hard to believe. But here's the video to show...

Irma sucks the ocean dry along beaches as it pulls water out to sea.

While it sounds ludicrous to say this is "normal", experts say this happens when an extremely powerful storm takes control. 

Look at this before and after comparison.

The water has returned to several of the beaches. But it doesn't always return gently.

And the sea life and animal world got rescued.
