Oh, wait a minute.

I see that.

Is that movement?

Yeah, yeah, yeah, yeah.

The harness should stop the road being wrenched from my hands by a heavyweight giant.

It's definitely something that yeah, there is.

And it feels like it weighs a ton, Really?

In the other one, other lines have to come up before I could bring in the beast on the end of mine, if they don't, fish could become tangled on trapped beneath the boat.

That was a very big spirit that is, in the weeds escape.

So the which is good.

This bizarre creature of the fuel floor was first described here in Trondheim.

It's an extremely rare sight of the surface.

The fantastical imagination of the Nordic map makers now seems quite tame compared with the reality of what's down there.

It's a very impressive looking at a very strange looking animal, very rare as well.

Apparently Fredrick saying any four of these court on rotten line before, So we gotta remember to take a tissue sample.

These things don't come to the light very often at all.

Frederick works with a scientist, a trump so university who collects all the data from his catches of sharks and skates.

It's the right color for the official.

I want the skin underneath.

Certainly got that rough field, but it's completely the wrong shape.

Skates are flattened sharks.

This is a very strange looking scape, but it's it's still not the fish I'm looking for after fishing 400 rod hours and reeling in 50 miles off line.

Is my luck about to change?

What's a good knowledge or Oh yeah, Oh yeah, yeah, it feels unreal.

Wait, now, Yes, it's not the lead, that is.

It's my last chance.

But is it the monster?

I've come so far to find 50 yards?

It could be another 100.

I've never had to pull any fish up such an extraordinary distance way higher than the Empire State Building.

There's a pulsing.

There's a very, very sort of slow pulsing that you feel If this is a Greenland shark and it's rough skin touches, the braid line will sever and I'll lose my last chance story and put the other lines comments to make sure that we don't get title.

I think it's getting there, but it's probably aware of we don't need these insights.

Okay, the Greenland shark.

It's just too big to bring on board.

We'd only injure it trying.

We'll have to tie it alongside this, a monstrous thing to find this far inland and to bring up from such a depth as well.

But we're just trying to get the tail rope on in there.

By the standards of what normally lives inland, this is this is huge.

This is monstrous when I'm tracking possibly £400.

Despite their enormous size, they're a mystery to science.

We know virtually nothing about how they live, read or hunt.

Small dorsal fin.

That's not your normal erect sharp dorsal fin is This was actually the surface.

You wouldn't see that characteristic triangle coming the surface.

It's just more of a smooth hump.

But if I want to get a closer look and if the fish can't come to me in the boat, I have to go to the fish.

I have no choice but to get into the freezing water with the world's largest predatory shark after the great white water.

Even through the dry suit, about 40 lads of undergarments it was called Hold This thing lives in it all the time.

But not up here.

Maybe half a mile down running color.

This came out and did right surface.

You wouldn't actually think it was a shark.

You wouldn't know what it was.

It has got this little upturned boat whole appearance.

What a beast this is.

It's believed they'll eat almost anything.

They come across down in the abyssal depths.

No one yet knows what potential threat they pose to humans.

He's probably getting close to the time when we should actually hook out when they got back to the debts.

Okay.

Asai, clamber out of the freezing fueled Frederick tanks.

The show in case it ever surfaces again.

All right, cool.

It's gone already on.

It just seems very un really now that it was here.

A lot of people even living around here.

No idea that creatures like that much right under their noses.

But could this mysterious giant be the creature behind the legend of Loch Ness?

I've considered the contenders from whales and dolphins to seals in sturgeon.

Andi even please your sores.

But one by one, I've had to dismiss them all.

But in Iceland, the home of the Vikings monster myths, I came across a real contender.

How could it also means one that ultimately led me to the one Greenland shark in this abyssal field in Norway.

But what I'm realizing now is just how special that encounter Waas to see that creature rise from the depths on the end of my line.

I've seen this thing myself.

I know it exists, and I believe it could have inspired some of the monster stories that the Vikings passed between generations and across the lands they conquered from experience.

I've learned that many legends hold a grain of truth.

I'm now wondering whether not just the myth but the animal itself ever surfaced in Loch Ness.

My journey has led me to a remarkable, immense predator, but it's so secretive that we know almost nothing about it.

But what we do know is that it lives in exactly the right part of the world, where it hunts in almost unimaginably deep, dark and cold water but are rare occasions.

It's also known to rise up.

And if you were one of the very few people to witness this creature in the flesh, you have no doubt that you'd seen a monster, perhaps even the ultimate river monster Legend of legends.
