Dornellas can be seen casually filming underwater when the shark makes a beeline for him, headbutting him with her nose.

The shark hit him with such force he appeared to knock the goggles straight off Dornellas' face as the man recoiled.

He said: "The shark broke my mask and smashed it against my face."

Dornellas explained that it's not the first time he's been hit by the shark but it was the first time he had taken a blow to the face.

He also mentioned that they later found out the shark was in fact blind in one eye which might explain why she hit him with such force, as she quite possible had no idea he was there.

Dornellas said: "She wasn't trying to bite me or be aggressive. After the collision, she took off – I think I scared her really badly, so I felt bad."

Luckily the scary moment hasn't put him off returning to the water, he managed to fix his mask when back above the water and carried on.

According to National Geographic, bull sharks generally live in 'high-population areas like tropical shorelines' and can even make their way inland through rivers and tributaries.
