The nervy moment is captured as a man in St. Petersburg, Florida drives his clear canoe near a dangerous bull shark in the waters of the Gulf of Mexico.

"When I saw this large shark in shallow water swimming in my direction, I headed towards him to see what kind it was and get a closer look. I kept expecting it to turn away because they are often shy. The large shark turned out to be a bull shark though, and bulls are not shy at all," said the filmer, who operates SeeThroughCanoe, about the encounter from March 18.
