Angler Marco Liebenow is celebrating today after smashing the world record for the biggest halibut fish ever caught on rod and line.
The enormous flat fish tipped the scales at a whopping 37 stone - heavier than an Asian elephant.
Marco, in his 30s and from Germany, jokingly thought he had hooked into a submarine when the monster halibut took his bait.
He had been on an angling tour with a company called Angelreisen Hamburg, which organised to fishing trip to Kjollefjord in Norway.
After taking 90 minutes reeling it towards the surface he and two friends tied a rope around the tail of the 9ft long fish and towed it back to shore, where it was weighed at 513lbs.
The halibut is among the largest bony fish in the world.
The native habitat of the Atlantic halibut is the temperate waters of the northern Atlantic, from Labrador and Greenland to Iceland, the Barents Sea and as far south as the Bay of Biscay.
It is the largest flatfish in the Atlantic and one of the largest species of flatfish in the world, reaching lengths of up to 4.7m (15 ft) and weights of 320 kg (710lb). It can also live for up to 50 years.
