British beach-dwellers beware: For this 450lb shark has been spotted lurking off our very own coastline.
Angler Graeme Pullen was fishing for pollock less than a mile off the north Devon coast when he hooked this 8ft long porbeagle shark.
Gamely shouting “Never mind the pollocks” to his fellow fisherman Wayne Comben, Pullen’s rod is seen bending double as he embarks on an almighty 30 minute fight to reel the monster in.

The shark was so big it sent Pullen’s 17ft fibre-glass boat spinning in circles.
The 62-year-old, who caught the epic encounter on his onboard camera, was able to tag the shark's dorsal fin before releasing it safe and well.
And it may well be the largest shark single-handedly caught by a fisherman in British waters.
Pullen has declined to give the exact location of the catch for fear of upsetting local tourism chiefs in Devon.

If true, the claim bears striking similarities to the classic 1975 movie Jaws in which the mayor of fictional town Amity is terrified the man-eating shark will drive visitors away.
Along with blue sharks, porbeagles are the most common species of shark found in our seas, but they don't normally arrive until early summer when the waters are warmer.
Porbeagles are a member of the same family as the Great White, although they are not considered to be a threat to humans with only three recorded non-fatal attacks before.
Pullen, from Hook, Hants, is a keen shark fisherman but was surprised to have caught one so early in the season.
The shark was tagged and released
He said: "We were less than a mile off the north Devon coast over a reef that we know doesn't get hammered by fishermen.
"Last year was a terrible year for pollock but on this occasion there was a glut of them. We caught 35 of them the day before and went back out again the next day.
"About two-and-a-half hours into the trip… I could feel something chewing on the bait and as it moved off I could feel it was a lot heavier than a pollock.

"I thought it was a tope - a smaller member of the shark family - but as I reeled it closer it grew heavier all the time and after about 40 seconds I realised it was a big shark.
"It was an enormous shark and when he swung his head from side to side his jaws opened right up showing his razor sharp teeth.
"Porbeagles don't attack humans but you can have a nasty accident with them like you can a chainsaw and it can give a hell of a bite."
The early appearance of the shark could signify a warm summer is on the way
At one stage Pullen was in danger of being dragged into the sea as the strong fishing line wrapped around his hand and he was momentarily attached to it and the shark.
He said: "Most shark fishing in this country starts in mid-June so this one was very early.
"The temperature of the water was 16 degrees and even though it's only May it is warm enough for sharks to be moving in.
"This could be a sign of a warm summer to come."
