Melanie Woods of Killen went to vacation at Panama City Beach on May 25 when several sharks swam into the sandbar.
She said the lifeguard began yelling for everyone to clear the ocean.
There were seven or eight sharks swimming. She caught the on video on her iPhone.
Woods said the lifeguard had been a lifeguard for four years and had never seen sharks in the area, nor had he heard of sharks swimming in water so shallow.
"I think I've touched the ocean for the very last time!" said Woods.
