Grandmother!

My grandma just drank a bit of soup.

Well one obvious source is dead sharks, Dead sharks washed up.

And as the shark came round, it would hit the net, the net would collapse on it.

Why don't you kiss your grandfather?

Did you give Grandpa his present'?

There's only 8,000 basking shark females in the world?

It became known as Simon's shark slime.

And keep an eye out for sharks.

They're the second largest fish in the world.

They're not protected in Ireland.

Yes, but don't forget. You foreign devil here.

And what you're trying to look at is the males have claspers, which kind of dangle out behind the back of the shark.

And sharks used to come into the bay.

We tagged 105 sharks last summer.

One is to try and work out the gender of the shark.

And sunfish is one of the words for basking sharks.

Some people say it's not population decline.

And Rus Hoelzel came up with an effective population size 8,200 animals.

And in about half an hour, we got five samples, five individual sharks, were sampled using Simon's shark slime sampling system.

So I was thinking that must have come from the shark.

So we rushed out to Blasket as soon as we heard there were sharks there and managed to find some sharks.

So if we can tell the gender of the shark before we sample it, we can tell the geneticist this was taken from a male or a female.

So you can quite easily tell the gender of the shark.

And being able to tell the gender of a shark has got very important for things like policing the trade in basking shark and other species through societies, because it is illegal to trade any sharks.

They're now listed as vulnerable under the IUCN.

The importance of basking sharks to the coast communities is recognized through the language.

That's banned now, and that'll be good news for the sharks.

So by just rubbing the mop handle down the shark as it swam under the boat you see, here's a shark that's running under the boat here we managed to collect slime.

So they were very important, and they were important for the oil out of their liver.

We use a pole camera on the boat to actually film shark.

And we thought that basking sharks were temperate animals and only lived in our latitude.

All it was doing was breaking my arrows because the shark skin is just so strong.

Basking sharks are awesome creatures. They are just magnificent.

You can only rarely be in the right place to find sharks into August.

They're often quite brief. They're often very seasonally constrained.

A third of the size of the basking shark is their liver, and it's full of oil.

So very simple things like that, we're trying to learn about basking sharks.

Before 2006, we had no idea of the genetic variability of basking sharks.

Now this was into August now, and normally sharks peak at June, July.

Probably the best documented basking shark fishery in the world is that from Achill Island.

They found that there was no genetic differentiation between any of the world's oceans of basking sharks.

If you're more interested, we have a basking shark website now just set up.

So it does seem to be that basking sharks, for some reason, have incredibly low diversity.

There's great concern that basking sharks are depleted all throughout the world.
