Diver's terrifying encounter with a great white shark (video)

A Florida fisherman caught a very unnerving close encounter with a great white shark on camera.

Joe Penovich, his 19-year-old daughter, and a friend, Zack Spurlock, were spearfishing off the coast of Port Canaveral on Saturday when they encountered the 12-foot shark.

Spurlock was the one who spotted the shark on his third dive.

According to Click Orlando, Penovich says: "I couldn't believe what I was watching. My voice is cracking and shaking. This thing was enormous and it had no fear."

The group were around 20 miles southeast of Port Canaveral spearfishing for lion fish for Penovich's restaurant.

Penovich said: "He came up and said, 'Hand me the Go Pro, there's a great white shark on the bottom.' I said, 'Are you sure about this?'"

He added: "Honestly, it was like a scene out of Jaws."

Zack uploaded the video to YouTube, with the caption: "This was filmed on my 3rd dive of the day in while out shooting lionfish for Grills Seafood.

"I was in 90ft approximately 25 miles SE of Port Canaveral. When I first saw the shark it was on bottom and slowly swimming south.

"I then see it pass by headed North a minute later. It swims by a third time and after it swam out of sight I decide it's time to head up to get the GoPro.

"My friend tosses me the GoPro and as I proceed to make my way back to the jug on the surface the shark makes a surprise appearance behind me.

"I would have never seen the shark behind if it wasn't for my friends yelling at me to turn around!

"The water was crystal clear for here so it's amazing to me how incredible these large creatures are at staying in your blind spot.

"Sorry for the video quality, was holding onto a gun, pole spear, and bag with lionfish fins poking through and trying not to drop anything!"
