Mooney Goes Wild

Greenland Shark Washes Up On Irish Coast For First Time

20 Apr 2026

Transcription

Chapter 1: What happened with the Greenland shark in County Sligo?

0.031 - 16.494 Derek Mooney

Now, the stranding of the Greenland shark in Finnesclin in County Sligo was widely reported in Irish and international media over the past week. It was first reported to the Irish Whalen Dolphin Group by Leaving Cert students from Sligo Grammar, Hamid Chowdhury and James Winters O'Donnell.

Hello, how are you doing?

0

19.679 - 23.664 Derek Mooney

Hello, how are you? So Hamid, first of all, tell us about this shark, how you happened upon it.

0

24.185 - 45.212 Hammad Chaudhry

Yeah, I know, it was an amazing find. Me and James were out on a run around Finnesclin When we came to a stop on the beach, not the beach, the harbour over there, beside the park, we looked down and we saw, we thought it was a rock at first, but then it was a bit of a weird shape to be a rock, so we thought it might have been a basking shark.

0

45.773 - 65.532 Hammad Chaudhry

But then we went down and quickly realised that it wasn't a basking shark. We took a few photos and we called the Irish Dolphin and Whale Group and they asked us to send them some pictures. And we did and then She texted us back an hour later, I think, told us that it was a Greenland shark, and we were both amazed.

66.113 - 72.762 Derek Mooney

James, had you ever seen a shark before? I don't want to sound totally ridiculous, I mean in the flesh, and had you ever seen a Greenland shark?

73.122 - 88.83 James Winters O'Donnell

To be honest, not really. I've never really seen a shark before, and definitely not a Greenland shark, because they're apparently very rare. But it was very exciting, actually, just coming across it. And what state was it in when you found it? It wasn't dead too long, I don't think. It didn't smell at all, to be honest.

89.371 - 93.518 James Winters O'Donnell

So I'm just wondering, how, James, did you know to contact the Irish Whale and Dolphin Group?

Chapter 2: How did the Leaving Cert students discover the shark?

93.539 - 109.266 James Winters O'Donnell

Well, I believe we looked it up. I think that was the first thing we decided to do because we didn't want to leave it there because it was quite a beautiful creature. So I think we looked it up and then we just gave them a call and they were very helpful, to be fair. I believe they called out some experts to confirm what exactly it was.

0

109.432 - 117.682 Derek Mooney

I know, because it's such a rare and unusual find. I mean, these creatures can live for hundreds of years, I believe. Have you learned a lot about them in the intervening period since you found it?

0

118.102 - 121.687 James Winters O'Donnell

Yeah, quite a bit. There's all the news articles and such.

0

122.247 - 125.812 Hammad Chaudhry

I learned that their flesh is poisonous to humans if you eat it.

0

126.412 - 131.438 Derek Mooney

But listen, congratulations and thank you very much indeed for coming on and telling us about it today because that is some find.

131.859 - 133.701 James Winters O'Donnell

Thank you for having us. It's been great, thank you.

135.031 - 143.333 Derek Mooney

So that was Hamid and James. Thank you very much indeed. And well done. What an extraordinary find. Dana, you're familiar with this shark, are you not? The Greenland shark.

143.534 - 163.01 Eanna Ni Lamhna

Well, yes, indeed. The Greenland shark is a most amazing creature. How old can it be? I mean, the one that was washed up in... they reckon must be at least 150 years old because it was approaching sexual maturity. It was a male, it had claspers and they only get these. So it was only a young fella. Apparently they can live, the oldest of them, up to 500 years of age.

163.39 - 169.038 Eanna Ni Lamhna

And a female, when she's gestating, the gestation period can last between 8 and 18 years. My goodness.

Chapter 3: What was the condition of the shark when it was found?

269.221 - 274.228 Derek Mooney

Well, Ken Whelan has joined us now. He's our fishery scientist. Ken, you were in Greenland, I think, last year or the year before?

0

274.588 - 292.732 Ken Whelan

Yeah, I think it was, yeah, 2022, yeah. So the Greenland shark, as Eanna was saying, I mean, it's very famous, obviously, for being so long-lived. But not just the Greenland shark, but quite a number of different sharks are very important to all of those different islands. I was smiling when Eanna was telling the story about the Greenland shark that you were presented with.

Chapter 4: Why did the students contact the Irish Whale and Dolphin Group?

293.092 - 295.836 Ken Whelan

I was presented not with a Greenland shark, but with another...

0

295.816 - 314.736 Ken Whelan

type of shark in the Faroes I can still remember the ammoniacal smell that ammonia burning my nose I couldn't face it and I'm sorry I eat most things but I really couldn't I should have had the drink with it but the interesting thing about the Greenland situation at the moment I was giving a talk for the Oceanographic magazine in London a few weeks ago and we were talking about Greenland

0

314.716 - 331.476 Ken Whelan

all the attention is on Greenland now and to some extent I hope from an environmental point of view it might help because Greenland is changing and it's changing fast and it strikes me as very interesting that one of these poor creatures should arrive on our coast at the very time when there's such incredible changes happening around Greenland.

0

331.456 - 352.683 Ken Whelan

And one thing I pointed out during my talk in London was the fact that we talk a lot about the Northwest Passage. But in fact, the other side, the Northeast Passage, is one that everyone from a political point of view, from an environmental point of view, are starting to look at. Because the whole continent is beginning to actually see a situation where there's water either side of the continent.

353.064 - 354.966 Ken Whelan

This is shifting and moving everything.

354.946 - 356.269 Eanna Ni Lamhna

What is the North East Passage?

356.349 - 357.713 Ken Whelan

And what is the North West Passage?

357.733 - 360.4 Derek Mooney

For the benefit of those who don't know, can you describe it vividly?

360.52 - 374.152 Ken Whelan

Yes, I can, yeah. Many, many years ago, a lot of the explorers tried to find this North West Passage. So what they were trying to do was they were trying to slip by, if you can imagine a map of Greenland and Canada on the far side.

Chapter 5: How old can a Greenland shark get?

517.013 - 518.535 Emily De Luce

Hi, I'm good. Thank you for having me.

0

518.555 - 527.445 Derek Mooney

Was it you who identified the Greenland shark for James and Hamid? Because certainly somebody from the Irish Whale and Dolphin Group did, and it was a woman, but they couldn't remember the name. Was it you? I'm just curious.

0

527.527 - 544.114 Emily De Luce

Oh, I wasn't the one who made the final identification. We actually had a few shark experts help us out with that as well to make that confirmation, such as Nick Payne and Taylor Chappell, who had a good look at it. But yeah, it had a very distinct smile now, that shark that kind of gave its identity away there.

0

544.134 - 546.598 Derek Mooney

Oh, really? You can tell a lot from a shark's smile.

0

546.983 - 556.222 Emily De Luce

Smell. You can, you can. Oh, smell or smile? Smile, smile. Its teeth are very distinctive and it definitely gave away what we were looking at there now, yeah.

556.242 - 562.174 Derek Mooney

Ken is asking, is there any records before now of Greenland sharks in Ireland? And he says, no, what do you say?

562.492 - 579.505 Emily De Luce

Ireland is technically still part of the Greenland Sharks distribution range. It is quite far south. You would expect them further north in the Arctic, the kind of sub-Arctic waters. But technically, Ireland and the northern part of the North Atlantic should still fall within its range. And I believe there's been...

579.485 - 599.155 Emily De Luce

less than a handful of sightings of sharks that were associated with fisheries, so potentially some deep-sea bycatch. But this is the very first time an animal has stranded, as far as anyone's aware, and the first time that we've had a, quote-unquote, coastal sighting then. Well, it was a stranding, but it was this close to shore and gave us access to the animal.

599.515 - 603.521 Emily De Luce

So in that way, it is incredibly unique to have had the chance to see that animal there yet.
