Shark capsizes man's kayak in Florida

An aggressive shark capsized a man's kayak along Florida's Atlantic Coast.

The terrifying moments were caught on camera.

It happened just off Stuart, Florida.

Ben Chancey was trying to catch a grouper when several bull sharks started swimming around his kayak.

One of the sharks swam under his boat and thrashed upwards, tipping the kayak over.

So, Chancey took no chances, and swam faster than he ever swam before.
