Visitors to the Greek island of Kos fled in panic as a monster shark, approximately three and a half metres in length, chased swimmers out of the water.
Chilling footage shows the beast dramatically circling the water with its fin sticking out on Kamari beach, in Kos.
Eyewitness Jackie Jones, 60, said the apparent predator was “swimming up and down” just 50 feet from the shore sending panicked swimmers dashing out of the water.
Jackie exclusively told the Sun Online: “I had only just got out of the water and I’m glad I did – I didn’t want to be its next meal.
“My husband saw something in the water and thought it was someone snorkelling.
“But we stood up and we could see it was quite clearly a fin.
“I was not going to get back in the water after that! It was very worrying because obviously there were still people in the water.”
“It was clearly feeding because it was on the surface and you could see his fin and his tail flipping around.
“I had a horrible vision that at any moment someone in the water would vanish like a real-life Jaws.”
The gran-of-two from Cannock, Staffordshire, travelled to the island with her husband Nev, to celebrate his 60th birthday.
The pair were enjoying a relaxing day at the beach when they spotted an alarming shadow in the water.
She added: “We could see it swimming up and down doing a figure of eight coming back on itself and its tail was flicking across the water- we could see how big it was.
“My husband has been snorkelling and you can see the fish and jellyfish but this was something else.
“I’m not happy to get into the water with something that big.”
Even though seeing the beast reminded Jackie of the recent shark attacks in Egypt, she said the couple is determined to return to their favourite island.
Secretary Jackie said: “We’ve been coming to Kos for 20 years and we’ve never seen anything like it.
“The next day we went back to the beach- we just stayed at an easy distance to get out quickly.
“I was constantly checking and looking if it was in the bay but it wasn’t.
“We will definitely go back to the island. It hasn’t put us off going at all.”
While it remains unclear what exactly the animal was, witnesses were adamant it was a shark.
The possible shark sighting comes as British holidaymakers have been warned after an increase in shark attacks in the Mediterranean.
The return of tourists after two years of Covid pandemic as well as overfishing could see sharks entering waters ever closer to humans in several holiday hotspots.
Most recently a popular beach in France was forced to close after a 6ft beast was spotted prowling near sunbathers.
To date, 51 species of shark have been recorded in the Mediterranean Sea, including the deadly great white shark.
Most scientists believe that human-shark encounters in the Med will become more common as the deeper waters where they live are increasingly overfished.
Certain areas of the Med have long been known to be home to sharks.
Sharks have been found across the Med, from Spain to Egypt, with dozens of attacks recorded in the past 20 years.
Since 2000, Egypt has seen the most attacks of any country in the region, with 20 recorded, four of them fatal.
Spain has seen the next highest number of shark attacks with 12 recorded in the same period, although all of the victims survived.
Outside of Egypt, three fatal shark attacks have been recorded in the Med since the turn of the millennium – two in Italy and one in Cyprus.
Speaking to The Sun Online, shark expert Alessandro De Maddalena said:
“The increase in sightings is due to three factors – the increase in human population, the fact that anyone today can photograph or film anything they see at any time thanks to the spread of smartphones and other devices, and the advent of social media through which such images reach a global audience.”
Expert Yannis Papastamatiou, an associate professor at Florida International University, told The Sun Online: “The chance of being bitten by a shark is extremely low and especially in the Mediterranean as shark population sizes are low.
“Of course, it’s never a zero chance! It’s not a good idea to be bleeding in the water, but having bleeding fish – and particularly struggling wounded fish – is going to be more of an attractant, such as spearfishing.
“Other things you can do is avoid the waters after heavy storms, avoid swimming at dawn or dusk, and avoid swimming close to river mouths.
“Be observant. Most of the waters in the popular beaches are very clear so if there is an approaching shark, someone will see it.
“When you swim, swim with at least one other person – that’s a good idea for general safety.”
