Panic hit our own shores when fishing expert Graeme Pullen claimed a great white – as seen in 1975 film Jaws – has visited Hayling Island, Hants, for two years running.
With its seven rows of razor-sharp teeth and the ability to grow to 14ft, an encounter with a great white would be potentially deadly.

Mr Pullen warns there have been "multiple sightings" and fears the shark will "stumble across someone in a wetsuit and mistake them for a seal."
Thankfully, it hasn't happened yet – but as attacks rise worldwide, should we fear they are closing in on us from the deep?
Coming face to face with a shark is a scenario most – fortunately –can only imagine. But for a few, it is not just the stuff of movies or nightmares, it's is a reality.
Last year had the highest number of shark attacks on record, with 107 reported worldwide.
Factors including rising water temperatures, shark cage diving excursions at tourist spots – where the creatures are drawn in with blood-soaked lures – and even normal sea fishing have brought sharks ever closer to our shores.

For anyone unlucky enough to face one in its natural habitat, the odds of coming out unharmed are stacked against them – although incredibly, some do escape injury.
Of the relatively few who have been attacked worldwide, as many as six out of every seven live to tell the tale.
Here, we look at the dramatic stories of just some of those who encountered a shark – and lived.
In an act of incredibly bravery, devoted husband Dean Gonsalves saved his wife when she was attacked as their children swam nearby – by punching the fearsome predator on the nose.
Dean stepped in to rescue Frankie when a shark clamped down on her leg and foot on April 9 this year.
The British mum was said to have been snorkelling with her husband off Ascension Island, in the South Atlantic, when she was mauled.

The couple's children – Louis, seven, and Katie, 10 – were playing in the water just metres away. It was only when Dean waded over and punched the shark that Frankie managed to break free.
According to a witness, the shark then lunged for Dean but, in a remarkable display of determination, the pair scrabbled to shore.
Hospital medics in capital Georgetown confirmed Frankie, originally from Letchworth Garden City, Herts, would not lose her leg.
But the mum, then working as a social worker in St Helena, had suffered deep punctures. She was airlifted to St Mary's Hospital in London for specialist trauma care a week later.
Hero Dean suffered only bruising from where he punched the creature. He reportedly said at the time: "Who'd have thought how hard a shark's nose is?" The species of shark involved is not known.
Frankie's father Irving Benjamin, from Deal, Kent, said of the attack: "Thank God it wasn't the kids. When
Dean called he made every effort to reassure us Frankie was alive and OK.
"But your first thought when you hear 'shark attack' is, 'Oh my God, I'm about to lose my daughter'."
College student Tyler McQuillen was attacked by a great white – and captured the ordeal on camera.
The footage, filmed on a GoPro and uploaded to YouTube, shows Tyler, 22, fending off the predator by jabbing it with a spear gun.
Tyler, from the US, was spearfishing with friends at Refugio Point, off the coast of Santa Barbara, California, when he felt a tug on his fins in September last year.

At first he did nothing, believing his pals were playing a joke on him by pulling at his feet.
But when the fin was ripped clean off and two of his toes were bitten, Tyler realised it was no prank – he was under attack from a shark.
Captured with the camera attached to the speargun, the four-minute video shows how Tyler briefly lost his grip of his weapon but managed to grab it before the shark is seen in full view.
In a desperate bid to defend himself, Tyler jabbed at the creature, thought to be just under 13ft long, before escaping back to shore.

Luckily for him, the shark did not give chase. Tyler's only injuries were two broken toes and a laceration to his right foot.
Emerging from the water after the ordeal, Tyler shouted to his pals: "I got that on video, wooo, f ** gnarly."
The footage – which went viral – serves as a harrowing souvenir of his brush with one of nature's deadliest predators.
In a remarkable tale of human resilience, Brett Archibold survived 28 hours alone in shark-infested waters after falling overboard in the early hours on a group boat trip.
The married dad-of-two was suffering food poisoning when he passed out and fell from the top deck during a holiday to Indonesia with nine friends.
When Brett, then 50, came to in the dark and rain, he was in the sea 15 metres from the boat – too far to catch up.
But Brett, a strong swimmer and surfer, was determined to survive. He was attacked by seagulls and endured "crazy" hallucinations as exhaustion and dehydration took hold.
Then after around 15 hours alone in the water Brett, from Cape Town, South Africa, felt a nudge against his left kidney.
He said: "I thought it was a barracuda initially, this big fish. Then the thing nudged me again and actually turned me in the water and I thought, 'Oh it's a shark, I know it's a shark'.

"It's weird the human mind. My first thought was, 'Oh he's going to eat me'. I remember lifting my chin and saying, 'Buddy, just rip my throat out'."
But when he saw the black edges of the shark's fin, Brett identified it as a blacktip reef shark – which he knew did not pose a threat to humans.
The realisation, he said, gave him renewed hope and in his delusional state he believed the shark could even rescue him by "towing me to a reef".
So much so that, when the blacktip swam away, Brett felt "devastated".
It was a further 13 hours before, at 6.30am on April 18 2013, Brett was found by a search party. He had fallen into the water 28 hours earlier, 20km from where he was found.
Shaking and in pain – his eyes swollen and his feet, lips and hands nearly bloodless – Brett was taken for a medical assessment.
He had lost nearly 13lb in body weight and was badly sunburned – but suffered no lasting damage.
Brett wrote a book about his experience, called Alone.
Mark "The Shark" Quartiano reckons he's caught 100,000 sharks in a fishing career spanning four decades.
Dubbed a "killing machine", the former policeman and fireman counts a 15ft tiger shark and a 20ft great white among his top catches.

He became a professional angler in 1976 – the year after blockbuster shark film Jaws was released.
On last count in 2011, he bragged of 100,000 kills – including the unborn offspring of pregnant sharks he slayed.
Quartiano uses state of the art equipment to reel in the largest of the world's sea life on his 50ft boat.
But his activity has divided public opinion. His site comes with a "Politically Incorrect" warning – and cautions that "some photos may not be suitable for very small children, the faint-hearted or PETA members".

But that hasn't stopped him acquiring 77,000 followers on Instagram and 236,000 visitors to his website last year.
He clocks up hundreds of daily likes on his footage, alongside hashtags such as #theworldsmostexcitingcharterboat and #SHARKHUNTER.
Quartiano claims to kill just a fraction of the fish he catches but his photos of bloodied trophies have made him an enemy of animal rights organisations.
His Miami-based business charges around £750 a day for fishing trips. Hollywood stars Robert DeNiro and Will Smith are among his customers.
Quartiano even runs shark-fishing stag dos, where the groom-to-be is allowed to reel in the catch of choice.
Shrugging off suggestions he is doing lasting damage to the ocean, he insists the number he kills is negligible in comparison to the tally of the commercial fishing industry.
But he notes: "There's definitely less sharks in Miami now. I'm probably responsible for that."
