Fears for beachgoers as ‘great white shark’s fin’ spotted off UK coast

A GIANT dorsal fin looms from the sea sparking fears a great white shark is stalking the Cornish coast.

Swimmers were told to beware as experts called the sighting exciting and terrifying.

Gran Jacquie Williams, 64, noticed the ominous shape 100ft off Gunwalloe beach, Porthleven, on Saturday.

Jacquie, who was with daughter Lindsay and her grandchildren, said: “It’s left me quite scared. It looked huge.

“We swim in the sea there when it’s a bit warmer. I’m going to have second thoughts now.

“The kids were stunned. It definitely wasn’t a seal or anything else. It was a big shark.”

Her son-in-law, Gazza Laidlaw, shared the pic on a Facebook group and said: “Any winter swimmers might want to proceed with extreme caution as it looks rather large.”

Naturalist and shark-spotter ­Hayley Bisofsky-Pope said: “It’s definitely not a porbeagle, basking or thresher shark. This is exciting and terrifying in equal measures.

“I’ve said it for a while that it makes no sense why we don’t have great whites here.

“We have favourable sea temperature and good fish stock and a fresh supply of seals. If it is a white we will begin seeing its impact on the seal population.”

Other experts have said great whites could be swimming up from the Med.

And in July a woman was bitten on the leg by a blue shark while snorkelling off Penzance.
