Caught on camera: Shark stalks two south Florida kayakers

Even more reason to stay out of the water. A video posted on YouTube shows a kayaker paddling his way through the waters off the coast of Florida. That's when we see a dorsal fin emerge from the water.

A look beneath the surface reveals a hammerhead shark, stalking the kayakers.
