NARRATOR: Sharks, dolphins,

Downloaded from
YTS.MX

an epic war
waged beneath the waves.

MAN: He's got a dolphin
in his mouth!

Official YIFY movies site:
YTS.MX

NARRATOR: Brain against brawn.

MAN: Oi, they're fighting,
they're fighting. Oh, (bleep)!

WOMAN: Dolphins are
very capable predators

in their own right.

MAN: People forget
that killer whales

are actually dolphins.

MAN: I've never ever seen
anything like this before.

NARRATOR:
Now for the first time,

a chance to see how these
gangs of the deep go to war.

Can there be a truce?

Or are these top predators
locked in a blood battle?

Off Australia,
predators stalk their prey.

These are called
false killer whales,

but they're actually dolphins,

just super-sized.

They grow up to 20 feet long

and travel in pods
of 10 or more.

Today they're on the hunt
for shark.

The pod gives chase.

The shark can't outswim them.

The dolphins work as a team,

box in the shark,

and move in for the kill.

FRANCES FARABAUGH: Dolphins
are very capable predators

in their own right.

NARRATOR: Frances Farabaugh
is a shark biologist

at Florida International
University.

FRANCES: I feel like
there's this conception

in the general public that
dolphins are the heroes

and sharks are the antagonists
or the villains.

NARRATOR: When it comes to
the fierce relationship

between dolphins and sharks,
there's a lot we get wrong

and a lot more
that we don't even know.

FRANCES: Both of these organisms
are predators

that are making smart,
intelligent decisions

about how to survive
and how to feed.

NARRATOR: Primal decisions
that often bring

these two top predators
into conflict.

In some areas,
30% of the dolphin population

bear the marks
of shark encounters.

And that's on the dolphins
that survived.

But even smaller dolphins
aren't defenseless.

They wield a powerful arsenal
of weapons to combat sharks.

FRANCES: It's a mistake to think
of dolphins versus sharks

as some kind of
mismatched pairing.

There are advantages
and disadvantages,

but they're quite
evenly matched.

NARRATOR: Frances is on
an expedition to gain insight

into the battle between
sharks and dolphins.

She teams up with research
specialist Kirk Gastrich

on the far side of the world

in what might be
the bloodiest front

in the shark-dolphin war:

a place called Shark Bay.

KIRK GASTRICH: In Shark Bay,
we know that

there are these interactions
between sharks and dolphins.

The amount of dolphins
with shark-inflicted wounds

on them is
really, really high here.

FRANCES: We know that
around 75% of dolphins here

show scars from
interactions with sharks.

NARRATOR: On the western tip
of Australia,

Shark Bay is a sprawling
natural preserve.

3.2 million acres of
pristine marine habitat,

overflowing with
fish and squid.

A dolphin paradise.

Only one problem.

KIRK: They call it Shark Bay

because this place is
just loaded with sharks.

NARRATOR: Frances and Kirk
have a lot of ground to cover.

Their floating laboratory
for the next week

is the 120-foot ship Infamis.

ASH: Straight in here, guys.
Welcome aboard.

FRANCES: Thank you.

NARRATOR: Rounding out
the expedition team

are Ash Sutton,
the ship's captain...

ASH SUTTON: If you've come
looking for sharks,

this is the hot spot
around here.

NARRATOR: ...and Duncan Brake,
an underwater cinematographer

who's been filming both sharks
and dolphins for 20 years.

DUNCAN BRAKE:
Dolphins seem to have

a bit of this love/hate
relationship with sharks.

I don't know, but there
definitely seems to be

this dichotomous relationship
between the two species.

NARRATOR: The mission
on the expedition:

capture video evidence
of shark/dolphin combat.

They hope to detail
how sharks outsmart

one of the most intelligent
animals on Earth,

and find out how dolphins evade

one of nature's
most efficient killers.

To get the footage, the team
has custom-built cameras

to attach to shark fins.

KIRK: We know that
there are interactions,

but we haven't really seen them
with our own eyes.

NARRATOR: Do the sharks hunt
during the day or night?

Do they target
the sick or injured?

All questions the fin cam
can help answer.

About 5,000 dolphins call these
waters home despite the sharks.

They've figured out
not just how to survive

but how to thrive.

FRANCES: There are lots of
strategies and advantages

that dolphins have when they're
trying to defend themselves.

One of them is that
they're very social animals.

We know that, through research,
they tend to hang out

in larger groups when they feel
they're more vulnerable,

like at night and
when they're resting.

NARRATOR: They also live
and work together in pods,

a cooperative that not only
provides protection

but is an effective means
to hunt prey.

FRANCES: They're very fast,
they're very strong,

and they easily
outmaneuver a shark.

So, it's important
not to think of them

as some kind of
David versus Goliath.

Dolphins are powerful,
incredible predators.

NARRATOR: Sharks don't
play well with others.

There are no shark pods.

They're solitary hunters.

And in this part of the world,

the number one threat to
dolphins is the tiger shark.

FRANCES:
From a dolphin's perspective,

a tiger shark is
always a danger,

because it only takes
one slip-up

for you to be consumed
by a shark.

NARRATOR: Tiger sharks
have earned themselves

a nasty reputation.

DUNCAN:
As an underwater cameraman,

you can be literally be covered
in other shark species,

but then that big, old
tiger shark will roll into town,

and you are looking at
that one big tiger.

NARRATOR: Named for
their distinctive stripes,

these apex predators
can top 14 feet.

And they have an outsized
appetite to match.

Unlike white sharks, which use
their immense power and speed

to take down seals
and dolphins,

tigers are all about
a casual kill.

DUNCAN: I think tiger sharks

are gonna sneak up
on something and grab it

instead of actually
having to chase it around

all over the ocean.

NARRATOR: Video footage of
tiger sharks fighting dolphins

is extremely rare and
extremely hard to capture.

But if the team can get it,

the footage could unlock
the secrets of this unseen war.

The first step is
to find the sharks.

The team uses a baited remote
underwater video, or BRUV.

FRANCES: With BRUVs,
I drop a frame with a camera

and some bait down to
the bottom of the ocean.

I pull that back up, and then
I watch the video through

to see what showed up.

♪ ♪

Make sure that that bait arm
is pointing down current,

and just make sure it's...

NARRATOR: Strong currents
can easily topple the BRUV,

so Duncan will check it out
on the bottom.

NARRATOR: Sharks can
easily detect prey

through clouds of muck.

FRANCES: Sharks sort of
have a sixth sense.

They can sort of electrorecept.

So they have these little organs
towards the front of their noses

that are called
ampullae of Lorenzini.

They kind of detect
little electrical currents.

And so they're not relying

necessarily exclusively
on sight to hunt.

NARRATOR: Remoras are fish
that cling to sharks.

They swim alongside and
feed on the host's scraps.

FRANCES: Large remora,
maybe a large shark nearby.

NARRATOR: A large remora
could mean

that a very large shark
is closing in.

FRANCES: I didn't read that.
Can you say again?

Duncan, Duncan, test, test,
can you hear me?

FRANCES: Excellent.

NARRATOR: The BRUV is rolling.

They'll leave it for a day

and then find out if they're
in the right spot for sharks.

DUNCAN: With this visibility,

it's probably time
to get out of the water

and let the BRUV do its work,
I think.

NARRATOR: Stories abound of
sharks sneaking up on swimmers,

and dolphins zooming
to the rescue.

In 2018, off the coast
of Australia,

a snorkeler diving
with a pod of dolphins

suddenly spots
a Galapagos shark.

These large predators are known

to take down
seals and sea lions.

Before long,
more sharks appear,

and they're getting closer.

But he hardly believes
what happens next.

(dolphins squeaking)

A pair of dolphins charge

and scatter
the threatening sharks.

(squeaking)

A dolphin pod has
safety in numbers.

When the matchup is one-on-one,
it's usually a different story.

MAN: He's got a dolphin
in his mouth!

NARRATOR: Recently,
two Australian oystermen

capture this savage struggle
up close.

JASON DARKE: I've never, ever
seen anything like this before.

Only on TV,
and even then, it's rare.

We were going about
eight kilometers out.

We were probably halfway there

when off in the distance
we noticed a fin

which we assumed straightaway
would be a dolphin.

A dolphin. It's a dolphin.

Jai, here, hold my phone.

JAI DARKE: And once
we realized the size of it,

there's no curve
in the back of it,

we realized that
it was not a dolphin.

JASON: This was much bigger
than a dolphin fin,

much, much bigger.

JASON: The shark
we knew straightaway

was a great white shark.

It would've been
approximately 10 to 12 foot.

Rather large.

He's coming this way,
he's coming this way.

He's coming right to us.

He's got a dolphin in his mouth!

He just swam straight past us
with a dolphin in his mouth.

JAI: This is (bleep)
you see on Nat Geo Wild.

NARRATOR: But then
things get wilder.

JASON: So, we'd been watching
the shark for a while,

and I was carefully
following the shark

as it was swimming away
with the dolphin,

when, all of a sudden,
out of nowhere...

Oh, my god,
another one, another one!

JAI: Oi, oi, oi!
Oh, (bleep)! Oh, (bleep)!

JASON: Oh, my god,
another one, another one!

JAI: Oi, oi, massive one,
massive one!

Oh, (bleep)! Oh, (bleep)!

Look at it!

Oh, that just come out
from underneath the boat.

The moment I saw
the second shark,

adrenaline started pumping
through my veins.

I didn't know
what just happened.

Oh!

That scared the (bleep)
out of me!

JASON: The second shark
was bigger than the first.

It would've been
12 to 14 foot, probably,

but it was definitely bigger.

JAI: It was huge.

Oi, they're fighting,
they're fighting,

they're fighting,
they're fighting!

Oh! Oh, (bleep)!

He just stole that dolphin!

He just stole the dolphin!

Oh, he's massive!

Oh!

JASON: Look at the size
of the thing!

NARRATOR: A dolphin is worth
fighting over.

FRANCES: We do know that if
a shark gets the opportunity

to eat a dolphin,
they absolutely will.

And in fact, it's a really
prized food source.

Like many marine mammals,
dolphins have all this blubber,

so that's a good
nutritious meal.

NARRATOR: From the injuries,
it's clear the dolphin

was initially attacked
from behind and below.

JASON: He swam
straight past us

with a dolphin in his mouth.

NARRATOR: How did the shark get
past this dolphin's defenses?

FRANCES: Dolphins are
really quite zippy.

They can outmaneuver a shark
fairly easily,

especially if they're
in deeper or open water spaces.

NARRATOR: To understand
how sharks catch

these slippery creatures,
the team heads to a beach

that offers a unique look
at Shark Bay's dolphins.

FRANCES: So, we're right now
at Monkey Mia in Shark Bay.

There has been 20 years

of really incredible ecological
and biological research

on the interactions between
sharks and dolphins.

NARRATOR: Dolphins were first
drawn here in the 1960s

by fishermen
sharing their catch.

Today the site is regulated by
the Parks and Wildlife Service.

FRANCES: We have some friendly
dolphins that come here

very regularly, and we get to
see them up close and personal,

which is really special.

NARRATOR: No need for
a baited underwater camera.

Here, dolphins come to you.

And they're covered in scars.

FRANCES: So this individual
that's just approaching us

just now is called Piccolo.

And you can see on her dorsal
and on her back,

she's got scars from
encounters with sharks.

Dolphins make this trade-off.

A lot of the food
that they want most

and the easy fishing grounds,
the yummy fish,

occur around
shallow seagrass beds.

Unfortunately, that's also
where tiger sharks

preferentially like to hunt.

NARRATOR:
To protect themselves,

dolphins have a secret weapon:
echolocation.

They can send out
a beam of sound

from a fatty part of their
head, called the melon.

The sound beam bounces back
and forms a mental image

in the dolphin's brain
of the world around them.

FRANCES: Echolocation is the way
that dolphins have to see

in dark and low-lit
environments.

Basically, it's like
radar or sonar.

NARRATOR: But there are limits
to this superpower.

FRANCES: So, it works kind of
like wide beams on a flashlight.

They can only see kind of
directly ahead of them

or to the sides.

So, if they get attacked from
the back or from underneath,

they probably won't see
the predator coming.

NARRATOR: Dolphins have
a blind spot,

and sharks know it.

NARRATOR: Great whites use
their massive power

to charge from beneath
in a breach attack.

KIRK: White sharks
you would consider

more of an ambush predator.

FRANCES: It's probably the shark
that you don't see

that you worry about,

because a lot of white sharks
rely on surprise.

They're stealth predators.

NARRATOR: It's easy to sneak up
on a lone dolphin,

but the safety of the pod
can stop an ambush,

even from a great white.

A white shark swims with
a group of dolphins.

The ocean-going mammals
show no concern

for the killer in their midst.

Their ability to communicate
and spot their stalker

gives the shark
no chance at an attack.

The team heads out to search
for more scarring,

and more signs of
shark/dolphin battles.

FRANCES: To our port now
just a little bit.

10, 11 o'clock.

Maybe 100 meters out.

KIRK: So, we've got
one dolphin up here.

Appears just to be logging or
just resting at the surface.

FRANCES:
It definitely has scars.

KIRK: That's the thing
about dolphins, though,

if they don't wanna
stick around, they don't.

NARRATOR:
It's a perfect display

of another dolphin
defensive weapon: speed.

They can reach
up to 22 miles per hour.

A simple flick of the tail and
they leave a trail of bubbles,

able to outswim most predators,
including sharks.

But there's a shark
that's even faster.

The mako.

DUNCAN: Mako sharks are one
of the fastest fish in the sea.

And compared to other sharks,

their speed and agility
cannot compare.

NARRATOR: Mako sharks are
torpedoes with teeth.

Blasting up to
45 miles per hour;

twice as fast as dolphins.

(woman screams)

WOMAN: Shark right here!

NARRATOR: Near Maui, Hawaii,
Captain Steve Lawless

captures a mako and dolphin
encounter off his snorkel boat.

(scream)

MAN: He's got the dolphin
in his mouth.

NARRATOR: The mako has
the dolphin by the tail;

a sure sign that the shark
outswam its panicked prey.

MAN: Has he swallowed
the dolphin

or is the dolphin hanging out
of his mouth?

DUNCAN: I think a dolphin
could quite easily

outmaneuver a tiger shark.

However, if we brought
a mako shark to the table,

not a chance.

WOMAN: This is crazy!

NARRATOR: Luckily for
the dolphins of Shark Bay,

there aren't many makos here.

But there are tigers,
and the team wants to know

if they're in the right place
to capture one.

Step one: retrieve the BRUV.

DUNCAN: How'd you guys do?

Everything back in one piece?

FRANCES: Everything's
back in one piece.

DUNCAN: I can't wait to see what
was down there with that remora.

NARRATOR: Is the footage
binge-worthy?

♪ ♪

Success: tigers on camera.

The team is in the right spot.

FRANCES: We know from BRUVs
that this is an area

that has a lot of tiger sharks
and many different habitats.

What we don't have evidence of
on these BRUVs

is exactly what
the sharks are eating.

NARRATOR: To really understand
the shark/dolphin relationship,

Frances wants to capture a
shark's-eye view of Shark Bay.

FRANCES: So, basically, what
this is, is it's our fin camera.

What happens is we'll slot this
over the fin of the tiger shark,

and we'll send it
on its merry way.

KIRK: Alright, good to go?
FRANCES: Good to go.

KIRK: Okay, got that?

NARRATOR: They set up
a series of baited hooks

called a drumline.

FRANCES: Ready to go.

KIRK: Alright, going over.

Alright, we're on bottom.

FRANCES: One down.

KIRK: One down, four to go.

FRANCES: Alright,
let's get the next one set.

NARRATOR: They check the lines
every 30 minutes

to ensure no shark is harmed.

FRANCES: Got a shark
on the line.

KIRK: Just want to see
what we got.

Coming up!

Hooked good.

Coming under, coming under.

FRANCES: Alright,
ready to go on that.

KIRK: Okay, on zero.

FRANCES: Zeroed.

Hold on.

KIRK: Watch it, Frances,
watch it.

I'm losing the head here.

FRANCES: Oh!

NARRATOR: There's a primal
conflict down in the deep:

dolphins and sharks.

MAN: Shark.
WOMAN: Shark.

JAI: Oh, he's massive!

(scream)

JAI: They're fighting,
they're fighting! Oh!

KIRK: Okay, on zero.

FRANCES: Zeroed.

KIRK: Watch it, Frances,
watch it.

I'm losing the head here.

FRANCES: Oh!

NARRATOR: Shark researchers
Frances Farabaugh,

Kirk Gastrich and
cameraman Duncan Brake

are at one of the fiercest
battlegrounds

in this ferocious struggle:
Shark Bay, Australia.

FRANCES: Many of the dolphins
that we've seen

have shown lots of evidence
of encounters with sharks,

very specific scarring
and bite marks.

So we know that these
interactions are occurring.

NARRATOR: Their mission:

capture direct evidence
of these battles

and observe offense
and defense in action.

Which strategies work?

Which don't?

JASON: He's got a dolphin
in his mouth!

NARRATOR: To do it,
they want to catch

the region's supreme predator,
the tiger shark,

and stick a camera on its fin.

KIRK: Pretty shark. Hooked good.

NARRATOR: They have
their shark, but...

ASH: It's a bronzie.

DUNCAN: That moment when you're
waiting for those stripes

to appear on the back
of the shark,

and then you see
a flash of bronze instead.

Yeah, it's almost heartbreaking.

You've got a shark;
it's just not the right one.

NARRATOR: Bronze whalers are
relatives of tiger sharks.

But they're not known
for attacking dolphins.

KIRK: We'll get the bolt cutters
ready, Frances.

FRANCES: Yep.

NARRATOR: The team decides
to hang onto their fin cam

and keep searching for a tiger.

KIRK: Nice.

FRANCES: Okay, it's gone.

We just released it straightaway

and it was a really
beautiful release.

DUNCAN: Right back
to square one.

NARRATOR: Of nearly
500 species of sharks,

only about 10
target dolphins as prey.

The usual suspects
top the list:

the tiger, great white...

JAI: Oh, he's massive! Oh!

NARRATOR: And hammerhead.

They mostly eat stingrays.

But a hammerhead will hunt down
a dolphin given the chance.

MAN: Look at that shark, dude.

MAN: I got it, man.
I got it all right here.

Holy (bleep).

NARRATOR: The notorious
bull shark,

a known man-eater,
makes the list.

DUNCAN: Bull sharks are
very bold and brash.

Kind of bulldoze other sharks
out of the way sometimes,

just to find out
where the food is.

FRANCES: Every species of shark

is going to have different
hunting modes,

different strategies, different
sort of niches that they fill.

NARRATOR: But when it comes
to hunting dolphins,

each of these different species
share a common trait:

size matters.

JAI: Oi, oi, massive one!

JASON: Look at the size
of the thing!

NARRATOR: To get past
a dolphin's defenses,

the rule seems to be a shark
needs to be as big or bigger.

But there are exceptions
to every rule.

Off the Florida coast, a young
blacktip shark is in pursuit

of a bottlenose dolphin
more than twice his size.

DUNCAN: Yeah, blacktip sharks,

every time I've been
in the water with them,

they always behave erratically.

They're like little kids
on a sugar rush,

kind of bouncing around.

They don't really care
about where you are.

They just want
the cheeky free snack.

NARRATOR: The shark's
running a risk.

His snack could attack.

The shark comes to his senses
and backs off.

♪ ♪

The team hopes to film their
own dolphin and shark faceoff

with a fin cam.

FRANCES: Alright, one more.

KIRK: So we just finished
checking the lines.

We re-baited everything.

We've got some fresh meat
on there for the shark.

FRANCES: Ah, I think we actually
got a shark on the line.

DUNCAN: As we were going around,

we noticed that both of
the buoys were underwater.

KIRK: Watch your feet, watch
your feet, watch your feet.

DUNCAN: So, like, for it
to pull both those buoys down,

it was gonna be a huge animal.

KIRK: Alright,
you can go neutral. Coming up!

DUNCAN: Yep,
here he is coming up.

KIRK: Alright, hold on.

♪ ♪

FRANCES: It's a tiger.

KIRK: Alright!
Got a bruiser of a tiger.

DUNCAN: I jumped in the water.

The water around here
is a little bit murky,

so we couldn't really
tell how big she was

until we jumped in there.

KIRK: Ah, it's a big one.
Big female.

FRANCES: Oh, it's huge.

DUNCAN: I've filmed tiger sharks
all around the world.

However, jumping in the water
here in Shark Bay

with these just huge,
just off-the-chart,

ginormous, mama bus tiger sharks
just blew my mind.

And it almost made
some of the other sharks

that had been in the water
look like tadpoles.

NARRATOR: Such a massive animal
demands extreme caution.

FRANCES: Our first priority is
the safety of everyone involved,

the safety of the animal,
and then getting good science.

NARRATOR: Shark secured.

But there's a problem.

KIRK: Alright, this hook's
straightening out,

so just be careful.

NARRATOR: A steel hook
is the only thing keeping

this powerful shark
safely in place.

And she's bending it.

KIRK: (bleep)
It's straightening.

NARRATOR: If she straightens it
much more,

this massive beast
will break loose.

KIRK: Yeah, you are big, I know.

NARRATOR: Frances and Kirk
have a decision to make.

KIRK: We can let her go,
or we can try to do a workup,

hope this hook doesn't
straighten fully

and we lose her before
we get the camera on.

FRANCES: Alright,
ready to go on that.

KIRK: Alright, Ash,
you can come on over here.

NARRATOR: They decide
to go for it.

KIRK: Come on up, Ash, we can
probably get a tail on her now.

ASH: Got it.

We got a line on the tail,
anyway.

KIRK: Yeah.

Once we lose control of the head
though, we're (bleep).

NARRATOR: Keeping control of
the shark's head is critical,

especially with her size.

A snap of the jaw
could mean tragedy.

KIRK: Hands!

DUNCAN: This huge tiger shark,
swinging around with its teeth.

Every time that shark
shook its head,

the hook straightened
a little bit more.

FRANCES: Okay, Kirk,
incoming with the tape.

NARRATOR: The closest hospital
is a six-hour boat ride away...

KIRK: Okay, hand me
the tape again.

NARRATOR: ...more than enough
time for someone to bleed out

if shark teeth
meet human flesh.

KIRK: Okay, I'm zero, Frances,
zero, zero, zero, zero.

FRANCES: Zero, I'm zeroed.

ASH: Okay, 3.8.

KIRK: 3.8.

NARRATOR: 3.8 meters.

This monster shark is
12 and a half feet long.

KIRK: She's so big.

NARRATOR: And the hook
is straightening.

KIRK: Ah, it's probably
gonna come out.

NARRATOR: If the shark
breaks free,

it could swamp the boat...

KIRK: Yeah, she's pissed.

NARRATOR: ...or charge
straight at Duncan.

KIRK: Maybe a little tighter
on the tail, Ash.

ASH: It's gonna get lost!

KIRK: Watch out,
watch out, watch out!

KIRK: Watch out,
watch out, watch out!

FRANCES: I got it, I got it.

NARRATOR: An almost
15-foot tiger shark

in Shark Bay, Australia,
might be just perfect.

FRANCES: It's huge.

NARRATOR: The research team
hopes to stick a fin camera

on the tiger's dorsal,

providing crucial insight
into the epic clash

between sharks and dolphins.

But there's a problem.

KIRK: This hook's
straightening out.

Watch your hands.

NARRATOR: The shark is
bending the steel hook,

the only thing keeping
her massive head still

and her bone-crushing jaws

away from underwater
cameraman Duncan Brake.

DUNCAN: This tiger shark was
on steroids, it was massive.

NARRATOR: Will the hook hold?

KIRK: If we're quick,
we might be able to do this.

FRANCES: Got it.

NARRATOR: It's now or never.

KIRK: Alright, Frances,
you ready?

FRANCES: Yep.

DUNCAN: That's pretty good,

that's going flush
down the body.

FRANCES: Okay.

NARRATOR: The fin cam is on.

FRANCES: Clear.

KIRK: Okay. Awesome.

NARRATOR: They send her
on her way.

KIRK: Dunc, I'm gonna do
release, alright?

(snip)

DUNCAN: I really
didn't comprehend

how big the animal was until
it started swimming towards me.

Then she went right between
my legs, and she was huge.

Then it swam off
into the distance.

The fin cam looked like
it was perfectly placed,

perfectly angled.

It's kinda creepy
because within seconds,

in this water clarity,
they just disappear.

KIRK: Cool.

FRANCES: Woo!

KIRK: We got it. Camera's out.

Now we're gonna check out,
see what these guys

really do with their time.

FRANCES: That is
a beautiful animal.

KIRK: Good work, Frances.

FRANCES: That was a truly
massive individual

and just a beautiful,
beautiful animal.

So I'm very excited to see
what happens next.

KIRK: Any information we get
back is gonna be novel.

So we're just really,
really excited

to see what we get
on this camera.

NARRATOR: Recently,
another camera captured

a shark/dolphin clash,
but this one flips the script.

DUNCAN: People forget
that killer whales

are actually dolphins.

They're all part
of the same family.

But they're bigger
than tiger sharks,

and they're more cunning
and more intelligent

than great whites.

If there's something
that I am more cautious

of being in the water with
than a shark,

it's definitely an orca,
a killer whale.

NARRATOR: Off Costa Rica,
a pod of orcas,

the world's largest dolphin,
target a tiger shark.

DUNCAN: Orcas are so intelligent

that they will
collaboratively hunt together

in order to take down
their prey.

NARRATOR: The pod
surrounds the tiger...

...trapping it at the surface.

(orca sings)

One orca moves in,

locking the shark in its jaws.

Now the rest of the pod
gets a piece.

DUNCAN: And what's more twisted

is that they won't even
eat the whole shark.

They'll dissect it and take out
a special little bit

that they like the taste of.

When you pitch an orca
against a shark

or several orcas
against one shark,

it's almost game over
every time for the shark.

NARRATOR: This battle
goes to the dolphins.

FRANCES: And just because
bottlenose dolphins,

the ones that are here,
are smaller

does not make them
any less shrinking violets.

They're still
very vicious predators.

NARRATOR: Back in Shark Bay...

KIRK: Is it getting stronger?

FRANCES: Nope.

NARRATOR: The team hopes for
their own amazing footage.

After a day hitchhiking
on the tiger shark,

the camera automatically
detaches and floats free.

Now the team needs
to track it down

in 3.2 million acres
of open water.

FRANCES: I think
we might've passed it,

'cause we're starting
to get weaker

and the signal's
coming from that way.

NARRATOR: They're fighting
the elements

and the setting sun to find it.

KIRK: As long as we're going
the right direction,

I'll keep looking.

FRANCES: Okay.

I don't know if
you can see behind us,

we're getting out of Shark Bay
and sort of into the ocean.

It's a race against the clock.

KIRK: Keep this heading
for a little bit.

(beeping)

FRANCES: If we don't find it
before sunset,

it's gonna be nigh on impossible
to collect at night

just because then we're looking
for a black thing

in a black ocean.

KIRK: I think we're
getting really close.

It's getting pretty loud.

FRANCES: Yeah?

(beeping)

NARRATOR: The camera floated
free a few hours ago.

The hope is that it captured
something never seen before:

a shark's-eye view
of that shark

going fin-to-fin
with a dolphin.

FRANCES: What we hope to find
when we get that camera back

is we're really looking for
how these organisms may interact

with their prey species,
including dolphins.

NARRATOR: Documenting a dolphin
encounter as a shark sees it

would be groundbreaking.

It could answer
long-burning questions

about these two top predators.

It could also capture
a whole lot of nothing.

FRANCES: The signal's definitely
coming from this direction.

KIRK: Let me have
a quick listen.

(beeping)

Got it right there! Right there.

FRANCES: For real?
KIRK: Yup.

FRANCES: Oh, I see it!
Yup! Ha ha!

Yes, Kirk. Well done.

That moment where we plucked
the fin cam...

KIRK: Got it! Woo hoo!

FRANCES: ...from
the sort of setting sun

and the seething ocean
was incredible.

KIRK: Ha ha ha!
There we go, guys.

Love it.

FRANCES: Now you have to
make sure that it all worked.

Well, we have footage.

KIRK: That's a good start.

FRANCES: Let's find the release.

And boom.

KIRK: There she goes.

Kicking strong.

NARRATOR: Shark Bay,
from the point of view

of a giant apex predator.

FRANCES: We did find it
way out in that offshore there,

so maybe she gets deeper.

Although we might lose the light
later on in the day.

NARRATOR: They've got
hours of footage

of this tiger on the move.

It's valuable data;

just not the eye-popping action
they hoped for.

FRANCES: This happens
in fieldwork all the time.

But when you only have
a limited window

and a couple shots
or maybe one shot at it,

when that happens, it's rough.

Yeah, it doesn't,
it doesn't feel great.

NARRATOR: Sometimes
it's a matter of being

at the right place
at the right time.

Captain Ash had recent
luck of his own.

ASH: So we're just filming
out here one day

and we saw this object.

See, that's a tiger
at the back of the boat.

So we just followed it,
four dolphins just appeared

out of nowhere with a juvenile
dolphin, you'll see them here.

See? See, that's the tiger.

Little juvenile
right in front of the shark.

We thought, "Gee, this tiger is
just going to eat

this juvenile dolphin."

And watch what happens when
the adults get involved.

They end up flicking
this bit of seaweed

in front of the tiger shark

and distracting it
from the little dolphin.

As if they're, like,
teaching the little dolphin,

"Don't be scared
of this tiger shark.

And just in case you get into
trouble, there's that seaweed."

NARRATOR: The pod of dolphins
work together

to keep the little calf
safe from the tiger.

FRANCES: I mean,
given the water clarity

and just also
the sort of maneuverable space,

they probably felt this was
a pretty low risk situation.

NARRATOR: Ash's footage
points out a potential flaw

in the team's
fin cam deployment.

The camera doesn't see
any dolphins,

because in daylight,
dolphins see the shark first.

Nighttime might be when
all the action happens.

The team has a solution:
a special night vision camera.

FRANCES: We know that tiger
sharks are active at night.

The real question is,

how are they interacting
with their prey at night?

NARRATOR: This camera can
answer that question.

It uses infrared technology
to peer into darkness.

KIRK: To my knowledge,
there has never been

a nighttime deployment of
a fin camera in Shark Bay.

NARRATOR: Night is when
these two top predators

bring all their weapons
to bear.

Their super-senses,
echolocation in dolphins,

electroreceptivity in sharks,

allow both to keep battling
after the sun goes down.

♪ ♪

They head north where
Captain Ash feels they have

the best shot at catching
a big tiger at night.

FRANCES: So, we're just
loading up the boat now

to go set some lines
to catch our sharks at night

so we can put on
our night camera.

So, we gotta go.

DUNCAN: A lot more swell
this evening.

There's a big storm front
coming in.

So, we've got a limited amount
of time to get this tag on.

ASH: Go get a tiger, mate.

♪ ♪

NARRATOR: If there's no shark,

they'll have to pull the lines
before the storm rolls in.

FRANCES: So, right now, we're
just looking for the buoys.

It's a little after 4:00 AM.

The wind has picked up.

So, fingers crossed, we get
a big tiger really quickly.

NARRATOR: They're in luck.

FRANCES: You see it?

ASH: There it is, dead ahead.

FRANCES: We have a big old
tiger shark on the line.

We're gonna work her up
as fast as we can

and go from there.

ASH: Alright. Ready?

KIRK: Yeah. I'm on it.

FRANCES: It's big.

KIRK: It's a big female.

ASH: You want a hand
or are you alright?

KIRK: Yup, coming down.

NARRATOR: Working a tiger shark
is hard during daytime,

but downright dangerous
at night.

Teeth and whipping tail...

all in darkness.

FRANCES: Stakes are high.

You know, we got one shot
left at this.

So we gotta try to make it work.

KIRK: Watch out,
coming up, coming up.

NARRATOR: Once again
Duncan dives in,

this time in ink-black waters.

DUNCAN: Whenever you enter
the water at night,

you've always gotta be concerned
of not what you can see,

but what you can't see,

and when the lights go out,
no one knows what could happen.

KIRK: Hold on.

FRANCES: Oh, (bleep).

KIRK: Watch it,
Frances, watch it!

NARRATOR: Shark researchers
Frances Farabaugh

and Kirk Gastrich are
wrestling a tiger shark.

KIRK: Coming down, breathing.

Okay, you good?

ASH: Yeah, I've got it.

NARRATOR: They hope to attach
a special nighttime fin cam,

but an incoming storm
and a thrashing shark

might make that impossible.

KIRK: Although there have been
daytime camera deployments

in Shark Bay,

there haven't been any
nighttime camera deployments.

Whatever we get back from this
camera is gonna be novel stuff.

So now that we've got the shark
alongside the boat,

we're going to finish
our workup,

attach this nighttime camera,

and let her go,
see what she sees.

FRANCES: Try to just get it
down a little bit more.

KIRK: Watch out, guys.

NARRATOR: The whipping shark
and the crashing swells

are not making it easy.

FRANCES: Come on.

KIRK: How we going with that,
Frances?

FRANCES: Almost done.

NARRATOR: Their underwater
cinematographer Duncan Brake

is capturing the action
up close.

Sometimes too close.

KIRK: Dunc!

Watch it.

You got it?

DUNCAN: Every couple of moments,
there'd be a massive surge

which would be pushing us
right in towards

the jaws of that
massive tiger shark.

KIRK: Far as you got it?
Okay. Cool.

Frances got the tag on her,
and she's getting restless,

so we'd better get her
back in the ocean.

NARRATOR: The shark is
ready to release.

They have to time it
just right.

KIRK: Okay, ready?
FRANCES: Ready.

KIRK: Ready?

ASH: Hang on, hang on.

Yeah, I'm ready.

FRANCES: He's ready.
KIRK: Good?

ASH: Yeah.
KIRK: Go.

ASH: You're off?
KIRK: Off!

ASH: Right-io.

NARRATOR: A first:

a nighttime fin cam deployment
in Shark Bay.

KIRK: Woo!
ASH: Awesome.

FRANCES: Yeah, that's a pretty
incredible experience.

So now it's just
a race against time

to make sure that we get the tag
as soon as it pops up,

and that we gather that data
and get it back.

NARRATOR:
But there's a problem.

ASH: Dead ahead, Frances.

KIRK: You got it?

FRANCES: Yep, got it.

So we were just headed on
our way back into the boat

and the tag popped off.

NARRATOR: Instead of hours,

the camera releases after
only a few minutes.

FRANCES: All of the,
what you had hoped

and you did all this work for,

it's just defeat snatched
from the jaws of victory.

You're so high and then
you just drop so low.

So here you can see
the animal and the boat.

And then floats back up
towards the surface here.

Bummer.

NARRATOR: But there is
a silver lining.

FRANCES: What this does is
the night vision camera works.

We can see the animal's head.

And it's encouraging to see
these, these images come back.

So it's something, an area for
further exploration, for sure.

KIRK: Off!

It came back with
our first glimpse

of some underwater nighttime
footage from these tiger sharks.

You get confirmation that
this technology could work.

NARRATOR: The battle beneath
the waves of Shark Bay

remains hidden for now.

But Shark Bay does reveal
something to the research team.

This war might not have
winners and losers.

FRANCES: I think it's a mistake
to think of this conflict

between dolphins and sharks
as a zero-sum game.

When it's in balance,

you end up with a healthy,
functioning ecosystem,

which is what we're looking to
better understand and protect

and preserve as we move forward
with a changing planet.

NARRATOR: This balance between
the ocean's supreme predators

is revealed off
the Florida coast.

A diver is in the middle
of a bait ball.

This swirling mass forms
as a defensive maneuver,

a way to confuse predators.

Predators like sharks
and dolphins.

But here, they put
their differences aside.

DUNCAN: So, when there's a big
bait school in the water,

all these sharks and dolphins

are collectively
working together,

collaboratively preying
on all these little fish.

When the ocean provides,
it's almost like the sharks

and the dolphins
have called a ceasefire

so that they can meet in the
middle and take down their prey.

NARRATOR: It's another glimpse

into the world of
sharks and dolphins.

(man yells)

One more chance to gain insight

into their complicated
relationship,

one that is changing
how we view each animal.

FRANCES: It's a mistake to think
of dolphins versus sharks

as some kind of
mismatched pairing.

It's not one that's like
a heavyweight champion

and one that's a lightweight,
by any means.

DUNCAN: With sharks
versus dolphins,

there's not ever
a clear-cut winner or loser.

It's just nature.
