Experts are predicting that it could be only a matter of years until we see Great White sharks prowling around in the coastal waters of Great Britain and Ireland.
As the seas around us warm up, more and more creatures that wouldn't usually venture so far north could be attracted to our waters by the new, more inviting climate.
Sharks might be particularly interested by the fact that the waters surrounding the UK are full to the brim of creatures that they find absolutely delicious.
Great Whites are found in most of the world's oceans. They've been spotting in the Mediterranean, the Pacific, the Atlantic, and the Indian Oceans. In fact, there have been claims they are already here. One was reported off the shores of Portsmouth, although these claims have not been verified.
Either way, experts reckon that within 30 years there will be more and more of the feared and revered Great White in our waters.
Dr Ken Collins, a shark expert from the University of Southampton, told The Sun: "You get Great Whites off the coast of South Africa where the water is colder than here and I see no reason why we should not have them in our waters.
''There are Great Whites in the Med, which isn't too far away and so I see no reason why they shouldn't be spotted here, particularly off the coast of Cornwall where there is an abundant supply of seals, which is their favourite food."
He continued :"Seals are like hamburgers to sharks - fat, juicy and meaty.
''The temperature of the water rise is barely noticeable, but if you take your traditional cod and chips, you will probably find that it hasn't been fished off our coasts but nearer to Iceland, where the water is colder.
''It would not take much of a change in water temperature from climate change, maybe less than one degree, for them to come here.''
The new research that suggest that we could be about to become infested with 5 metre long killing machines was done in conjunction with National Geographic's week-long 'Sharkfest' which runs for the whole of this week.
It's not just Great Whites that it is thought could move north in the future, either. There could also be hammerheads, black tips, and tiger sharks.
Before we get to that, there are already around 40 types of shark in our waters. In fact, since 1900 there have been 38 shark attacks in British waters. That's second only to Italy (with 50) in Europe.
The best defence against a shark attack is to poke the creature in the eye or punch it on the nose.
Good luck avoiding the huge gaping mouth, though.
The best defence, really, is to just stay the hell out of the sea.
