Anna Maria Island, Florida -- Coming home from a fishing trip on Anna Maria Island, 19-year-old Aaron Smock and his dad got quite a close surprise.
"We noticed a really big shadow out there!" said Aaron.
It looked like a hammerhead shark chasing a tarpon for dinner within just a few feet of their boat.
"It's an amazing experience. I can't even describe it. He was pushing it around as fast as possible, like a toy!" Aaron said.
