off antarctica,

Building up blubber reserves

Over 30,000 humpbacks

Narrator: Ryan johnson
is a shark scientist

Based in mossel bay,
south africa.

He's been studying
the white shark population here

For over 20 years.

Ryan: Whoa, there we go!

Oh, she went for it!

Narrator: In February 2017
he was flying his drone

During a shark survey
when the phone rang.

Ryan: The phone call came in

From the national
sea rescue institute

there was a whale out at sea.

Narrator: It bit the tail,

Then it rolled

As if trying to drown it.

This was not some
random meeting.

It was a methodical attack on
a whale by a great white shark.

A shark that seemed to know
just what to do.

Ryan is the first person ever
to witness this shark behavior.

He played the drone footage
over and over

And suddenly
recognized the shark.

He tagged her for research
back in 2012.

Her name is helen.

Ryan: Dorsal fin came up
out of the water,

And you could clearly see the
satellite tag remnants on her,

Plus that distinctive
dorsal fin.

Now that she is that shark
that hunted a humpback whale,

A living humpback whale,
she has sort of marked her place

In the sharks'
hall of fame forever,

And she's always gonna be
remembered for that.

Narrator: Ryan had
serious questions.

Is this shark attack
a one-time-only event,

Or do white sharks
really hunt living whales

And we just never see it?

To get some answers,
ryan decides to dig deeper.

He sets off to follow

The 4,000-mile migration route
of the humpbacks.

Are there specific places where
white sharks ambush the whales?

Do attacks follow a pattern?

And why hunt whales at all

When there are plenty
of seals available?

Ryan goes back to
what he already knows

About the great white.

11 million years of evolution
has made them fast...

Agile...

...And calculating.

Most shark species
are cold-blooded

And have to stay
in warmer waters.

♪ ♪

Great whites are one
of only seven species

That can raise their
internal body temperature.

Being warm-blooded, they keep
their edge in cold water,

Which is why no seal is safe

Off the coast
of southern africa.

For them, white sharks are
an almost unbeatable foe.

So, why would white sharks

Spectacular breaches

Show just how these sharks
have been hunting

For millions of years.

They know how to hunt seals.

So, the question ryan
really wants to answer is,

Why would they hunt
something much bigger

And much more dangerous?

Narrator: Ryan begins
his research at seal island

Just off mossel bay,
south africa.

It's a well-known hot spot
where great whites hunt seals,

And it's just
three and a half miles

From the site of
the humpback whale attack.

Seals and humpback whales
are as different

As they can possibly be.

What connects them
in a shark's brain?

It's well-known that their diet
is mostly marine mammals.

But just how selective
is the great white?

Ryan runs an experiment

With two different sized
seal decoys.

Which one will
the sharks attack?

Ryan: For me, this experiment
is all about

That cognition of a shark,
that decision-making process,

When it weighs up the pros
and cons of attacking a prey.

Does it go from that
extreme level of success,

That big reward but high risk,

Or is it going to be
more conservative?

Because this feeds right
into the decision-making

Helen had to go through

When she was faced with a whale
nine, ten times her size.

She had to be
assessing the risk;

The chance of her
getting injured;

The chance that she
would be unsuccessful;

The chance that her life
as a predator could end.

Narrator:
Do the sharks display

A simple species preference,

Or is there something more
to their selection?

Ryan: Make this turn
as tight as you can,

Because there's no swell,

And we just head right up
the edge of that island.

Nice one.

A little shark,
but hit the little decoy,

Hit the little juvenile pup.

Barry skinstad:

Ryan: Wow.

That is something else.

I tell you,
that's something else.

Narrator: It's a clear message.

Against the odds,
white sharks are able to pick

The perfect moment and execute.

It's the same ability
helen used

When she attacked
the humpback whale.

Nothing random about it.

Ryan: How that shark snuck up
and was successful,

One second it was there,

And the next second it was
feeding and thrashing.

Yoh.

You think you've
witnessed it all,

You think you've seen it all,
but you ain't seen nothing

Until you've been in the water
with a hunting great white.

Narrator: Hunting great whites
have one very subtle ability

Over all the others.

They can detect the moment
of maximum vulnerability

And exploit it.

Helen used her intuition when
she went after the big whale,

And she had extra
motivation to do that.

In winter, small seals are
plentiful and easy prey,

But in the spring when
the seals have grown up,

They're more difficult
to catch.

So, the sharks must
adapt their diet.

They're headed to mozambique.

Humpbacks are the fifth
largest whale species.

They can reach up to 60 feet

That's three times longer
