It's 1972. A young British family is attempting to sail around the world when disaster strikes.
Their boat is hit by killer whales and it sinks in seconds.

All they have left is a life raft and each other.

This is the true story of the Robertson family and their fight to survive, hosted by me, Becky Milligan. Listen to Adrift, an Apple original podcast produced by Blanchard House.

We're here with day two of our week of sharks, inspired by the 50th anniversary of the movie Jaws.

And today, we're going to jump in the water with them. Well, I am.
You two two get to just sit in your cozy little offices and hear about really out of the way. Fair point.
Fair point.

But before we get into the water, I think we should actually start with the onslaught of shark movies that were inspired by Jaws. All right.
So there are 180 or so monster shark films. Wait, 180?

With our Monster Scholar from episode one.

There are at least 180 that are listed on the Internet Movie Database. Jeffrey Cohen.
I definitely know Sharknado. What else is there?

You know Sharknado, but do you know Sharknado 2, 3, 4, 5, and 6? Oh my gosh. Where in part 6, they return back in time to Sharknado 1.
Well, of course. So, I mean, the deep blue sea.

We are stuck in the middle of the ocean. Open water.
How big is that thing? The Meg, followed by a cheap remake called Jurassic Shark, which is not nearly as good.

The reef, Ghost Shark. In that one, even if you kill the shark, you're not done because its ghost will come back and get you.
They've tasted human flesh.

Two-headed shark is exactly what's advertised. No.
Double the trouble.

Followed, of course, by three-headed shark in 2015, five-headed shark in 2017, and then six-headed shark in 2018, at which point it looked like a starfish with all kinds of shark heads on it.

Oh my God.

There's almost every kind of shark movie, and what I love about the whole shark genre is that it looks to free the shark from the constraints of being underwater so that sharks can be everywhere.

There's sky sharks,

but they can fly. Avalanche sharks.
They swim through the snow like other sharks move through the water. Bait.

I can make it. This is about sharks in a supermarket.
Where are they in a supermarket? Well, the supermarket does flood.

There's just movie after movie like this.

So Jaw has like kicked off this world, like this universe of shark monsters, taken them out of their world and like dragged them into ours.

And I kind of just wanted to go do what Rodney told us to do yesterday, like go and see it for myself.

I mean, I know this worked for your guy, that seeing it

made him less afraid. But like, I mean, I think you're going to go down there and see, like, oh, this thing is bigger than me.
It is capable of completely tearing me to shreds. Like,

there is a possibility that you're gonna get down there and

just be more afraid of it. Yeah.

But

I think I actually want to know. So, all right.
How'd you exit the aircraft? Please mind your head on the.

I hopped on a plane to this town in South Australia called Port Lincoln, informally known as Tunatown. It's this little fishing town, and that's where Rodney's cage-diving boat leaves from.
Okay.

We got the shark on the side and everything.

Got to the dock. We drop our bags.
We do some paperwork.

Basically, like sign away our lives. And then we

set sail.

Where we will spend the next four days looking for great white sharks.

Is there a lesser white shark? Well, so this is actually, it's a good question. No, there's not.
It used to be like the white shark all along.

And then once they started becoming scarier and scarier around the era of jaws, we we started calling them great whites to add fear to them yeah what they just added it's not like actually the scientific name yeah no so all the scientists now you'll hear them just say white shark because they're it's like rebranding the shark huh okay so you're on the boat yep and how many people are there i think it's like 15 passengers plus the crew okay i come from

these people are from all over the world

new york city best place on earth i'm from japan and they're all so excited to see a white shark i want to see the great white shark.

Which was just like a fascinating little world for me to drop into. I'm passionate with sharks.
Because, you know, like most people hope they never see one.

I want to meet the apex predators in their natural state. There were these two brothers.

We love sharks more. You or me.
Two were so into sharks. I think I do, yeah.
They were competitive about it. I love them, but he adores them.

The older one said that when he was in kindergarten, he did a presentation about sharks. And I even wrote it wrong on the board with a CH, so just such sharks.

Because I didn't know English, but I knew a lot about sharks. And he ended up getting in trouble because he had taken these books out of the local library.

And I was so amazed by the shark pictures in the book. So I cut out the pictures with the scissors.
And I was like looking at the pictures in my room and being so obsessed with them.

That's amazing.

You just picture like the exact silhouette.

Yeah, exactly.

So from Port Port Lincoln, we sailed for hours, like four, five, six hours, to this remote group of islands called the Neptune Islands. There was a wild, rough sea bumping against the rocks.

I will describe it as rough.

Yeah, very rugged, like dark blue water, dark gray rock. It seems sort of barren, but...
You feel that there's something around here.

It's a feeling, you know? As soon as we anchored there, we noticed this intense smell, which is actually coming from us.

I think that's called channel. It's like minced up bits of fish guts and skin and heads and stuff.
The crew is throwing like buckets of fish parts off the back of the boat.

I have a hat with a ribbon on it that says Master Beta. And I just see that white thing.
What was that?

All of a sudden these colors start flashing across the water. What? White and gray and silver.
And they look like little sharks if you don't see their mouths. But no sharks.

They're not sharks. No shark, we're sharkless.
Which is kind of the point. The bait is supposed to attract the smaller fish, which attract the sharks.

But

a day went by. Are we seeing anything?

No, no kids, not yet. And then another day...

Nothing. Nope.
I see border. And there was just nothing.
It's wild to me. You're pouring like blood, meat, flesh, fish, corpses, all this stuff in, and it's like days.
Days.

I would be like, oh, they'd be there. They'd go

exactly,

you know, and they'd be there within 34 seconds. I know, I know, but that's not what happened.
So two days have passed out of four, and we haven't seen a single shark. Wow.

And so there's just this cloud like looming over the boat. And so we go to bed that night and we're like, we really hope that tomorrow, like, we'll see one.
No, I'm sorry, though. I, I'm sorry.

I need, I need for the rest of us who aren't in this deranged epicenter of the world where you want to see sharks.

Like, I love knowing that you poured gallons of blood into the water and didn't see the sharks. Yeah.
This is the best

great news for you. Yeah.
It's really, it kind of like you're in the sharkiest waters of all waters and they're not coming.

And so like the next day, bright and early, the first cage goes down because they send the cages down even if they don't see a shark on the top just in case there's something down there. Yeah.

So I'm up on the top of the boat next to the skipper because he's the one that controls the crane.

And then suddenly

he pauses. I don't know if she just said five pulls there.
He feels five pulls on this string. Oh, I thought it was five.

The string that runs down to a cage they've lowered 60 feet to the bottom. And the people down there, they'll pull on the string to communicate with the surface.
Five pulls for a shark, so hopefully,

it is one down there. And eventually,

the skipper winches the cage up. Okay, guys, can you report back?

We did, we saw a white shark. And they had actually seen the shark.

They were so excited.

And then all of a sudden it was my turn. Like the crew was like, get your stuff on.
We're gonna start getting ready. We're gonna do it, okay? It's go time.

Okay, and how does that feel?

I'm a little bit confused. I'm a little bit like, I'm so happy that we finally have a shark around.
Like it had been so long, but then I'm also kind of nervous when the reality of it set in.

Like, oh, it's actually down there.

It, it kind of feels like what you're in a lion to just go on like a terrifying roller coaster, and you've just seen all of these people with like shocked, smiley faces like tumbling off, and then you get buckled in, and there's like no turning back.

Like, it feels both exciting and terrifying.

Okay, guys, welcome to the cage.

Is anyone in the cage with you?

Four people fit. One of them is a dive master.
So So you're with someone at all times.

And once the four of us settle into the corners of the cage, our dive master signals to the skipper.

We're ready to go down.

So we get dropped down like we're taking an elevator deep into the ocean.

And as we go, it gets darker and darker and darker. And you can see less than less because you're getting further away from the sun.

And eventually we get down to around 60 feet and the cage stops moving.

And all I can see is this barren sand of the ocean floor. And above it is just this abyss of blue.

I was bracing.

There was just like so much fear building of what's going to come out of that blue.

And and like when is it gonna come out and which direction is it gonna come from

all I can hear is the sound of my breath which was very heavy

and then I hear this scraping sound

and it's the dive master scraping this little metal knife against the side of the cage And the sound is supposed to get the sharks interested to come closer, but it kind of feels like a dinner bell.

And then I feel a tap on my shoulder, and I like look over to the left, like behind my shoulder. And it's this, the dive instructor.

And she just puts her hand in the shape of a fin on top of her head, kind of like to signal shark, and then points into the corner. And as I turned, I remembered this thing Rodney had told me.

Don't just look at their heads, their teeth, because everybody's frightened of their teeth.

Look at the rest of the body.

And then out of the darkness, it comes, truly out of the darkness,

swims this white shark.

It was a young one, so it was smaller. Six and a half feet, gray top with this scraggly white line and belly halfway through it.
Little black tips on the front fin.

But the thing that's most striking about it is the way it moved.

No thrashing or darting like in the movies.

Just sort of floating.

You know, they fly like aeroplanes, or aeroplanes fly like great white sharks.

They have to dip a wing to turn.

And their moves seem to be incredibly deliberate and relaxed. White shark researcher Greg Scomal.
They don't do anything that's going to waste their time.

The shark, it kind of felt like it was orbiting us.

Like it kind of fades in and out of your view and comes, it goes in and comes out and goes beneath you and then it kind of comes towards you. It's just like, wow.

It's beautiful.

You're looking at a prehistoric beast, millions of years old.

Like it was carved by time to be exactly where it is.

Sharks are 465 million years old. You know, they've been on Earth for such a long time.
This is John Long, strategic professor in paleontology at Flinders University in South Australia.

Now, that amount of time is hard to wrap your head around, but John helped me. They're more than twice as old as dinosaurs.

They're way older than trees. Flowering plants.
They were around before Everest was even a mountain. All of the continents that we live on today, they looked nothing like they do.

They're even older than the rings of Saturn.

And I mean, over these eons, sharks had to survive all five of Earth's major mass extinctions. Volcanic eruptions, a massive asteroid, ice ages, out-compete other major predators.

Gigantic pliosaurs with banana-sized teeth and walking whales. And along the way, they just absolutely exploded in diversity.

So that today, sharks fill so many different niches. According to Jade Elcock, a shark researcher at the Woods Hole Oceanographic Institute, they are all over the place.
There's sharks in the tropics.

There's sharks in the Arctic. I mean, a bull shark was found so far up the Mississippi River, it was in Illinois.

There's all these different versions of sharks, carved in their own bizarre ways. It almost makes the white shark seem boring.
If you love the white shark, no hate to you.

I also love the great white shark. But sharks are incredible.
They are diverse. I'll just go through a bunch of them.

Take it for the duck. I mean, some sharks only get to be about eight inches long.
Well, the largest whale shark was almost 62 feet long. So just the sheer difference in the size range.

We have glow-in-the-dark sharks, like lantern sharks, that glow on their bellies.

There's a shark species that spews bioluminescent goo from pockets near its fins, likely for avoiding and confusing predators. No way.

The rig shark can snap its teeth together to make kind of a clicking sound.

While the swell shark will swallow a bunch of seawater, blow up like a big sharky water balloon,

and that makes it more difficult for predators to eat it.

And of course, the Greenland shark can live literally hundreds of years.

I'm sure there are Greenland sharks in the ocean right now that were alive during the time of Alexander Hamilton and the time that the musical about his life was written.

Isn't that wild to think about? Yeah. Hundreds of years.

And there's even a shark that might help us survive one of our greatest threats.

That's tomorrow.

Okay, we just got back and we saw our first sharks. Yeah, we tried to kiss it, but it wasn't far away, actually.
