The terrifying moment a ferocious great white shark attacked a cage containing a diver has been caught on camera.
Screams of fear can be heard from the female divers as the beast's jaws wrap around the bars.
The attack took place in South Africa which is regarded as one of the most shark-infested areas in the world.
New Yorker Hillary Rae Petroski captured the terrifying footage on her underwater camera and at one point is heard screaming: "Oh my god.'
Diving in a cage with sharks is a popular activity in South Africa and in an interview with the Guardian a trip guide said:
"Each year fewer than 10 people get taken out by sharks... that's compared with more than 400 killed by electric toasters."
Great white sharks are the largest predatory fish on Earth and they can grow to an average of 15 feet in size.
They are highly adapted predators and their mouths are lined with up to 300 sharp angled triangular teeth.
