Going by the current state of affairs, God knows what state the UK will be in in 2050. But according to one oceanographic expert, the future involves a lot more sharks than we envisaged, as the UK is going to become encircled by ten species of shark which will have shifted northwards due to warmer waters brought on by climate change.

That includes the oceanic whitetip, which Jacques Cousteau called "the most dangerous of all sharks" and is thought to be responsible for the most human deaths of any species.

Dr Ken Collins, a senior research fellow at the University of Southampton based at the National Oceanographic Centre, said in a statement: "It's likely we will be seeing more sharks spread from warmer regions such as the Mediterranean Sea towards our waters in the UK over the next 30 years.

"These include the likes of blacktips, sand tigers and hammerheads, which are currently found swimming off the coasts of Spain and Portugal."

The waters around the UK are already home to sharks including basking, nursehound and thresher sharks, and Dr Collins forecasts that they'll be joined by longfin mako, bronze whaler, oceanic whitetip, silky, dusky and goblin sharks as well as blacktips, sand tigers and hammerheads.

"Obviously", you're probably thinking, "the next logical step from Brexit is to turn Britain into a citadel surrounded with a shark-infested moat." However, the sharks on Dr Collins' list generally aren't dangerous to humans.

Apart from the oceanic whitetip, that is.

Despite official stats listing the great white, tiger and bull sharks as the most dangerous to humans from unprovoked attacks, oceanic whitetips are the species thought to be responsible for the most human deaths from shark attacks as they tend to hoover up survivors of plane crashes and sunk ships and castaways rather than attacking humans unprovoked closer to shore.

Well, that's reassuring.
