A menacing fin was seen off the coast of a Welsh seaside town. The beast was spotted just yards from shore near Porthcawl, in south Wales
Residents were split over what type of shark had been sighted. Some believed it was a basking shark, which is found in UK waters, although not typically in November.
However, others felt the pointed shape of the fin indicated it was a man-eating great white shark made infamous by the Hollywood film Jaws. Whilst they have never officially been recorded in British waters, there have been several unconfirmed sightings.
The fin was spotted by Dan Santillo on Saturday (November 15), as reported by What’s The Jam.
He said: “It was moving but slowly. At first, I thought it was a sunfish. But I’m not sure what it was. A lot of people suggested it could be a basking shark.
“But some people thought it was a Great White too. It moved across the entire bay. And didn’t go under the water once. It’s there for about 30 minutes. It was very cool to see.”

Residents were divided about what it was. One said: “Basking sharks and Great Whites have very similar-looking dorsal fins, and given the size of both of them, it can be hard to tell the difference from the surface.”
Another said: “That’s a basking shark. Was out surfing once, and one went under my board. There were sightings of a great white in an estuary in Cornwall at the time, so I completely wet myself.”
Another observer speculated: “Could be all sorts, a basking shark, mako shark, or porbeagle shark.”
Whilst someone else remarked: “I don’t know what it is, but I’m not going near it.”

Basking sharks, the largest largest shark found in UK seas, aren’t typically spotted off the British coast in November, as their seasonal migration concludes during autumn.
The usual period for basking shark sightings in UK waters extends from April through to September, with the majority observed between June and September.
These large sharks are highly migratory creatures and head offshore or move southwards during the winter period.
Meanwhile, whilst there has never been a verified sighting of a great white shark in British waters, there have also been a small number of credible reports since the 1960s.

Richard Peirce, an expert and author of Sharks in British Seas, has examined nearly 100 claims from individuals who believed they encountered great whites in UK waters. He considers just 12 of these encounters to be credible.
Given that some may be duplicates—where multiple people spotted the same individual shark—that figure is reduced further to approximately seven possible sightings.
