All language subtitles for Spy In The Ocean 02

DAVID TENNANT:
The world's oceans are full of wonder...

an alien world, waiting to be explored...

a place of extraordinary Iifeforms

with intriguing social lives

and incredible intelligence.
— DOLPHIN SQUEAKS

To reveal their secrets,
a hidden team goes undercover...

spy creatures.

The most innovative
undersea robots in the world.

They not only look like the animals they film

they interact with them as no human can.

Equipped with hidden cameras...

they reveal their astonishing lives.

As our spies join their undersea world...

they shed light on
some of the mysteries of the deep.

Last time, our spies looked at
how ocean creatures think.

This time, they explore how they feel.

As we dive into the world
of animal emotions

we can't help but be moved

for their feelings aren't that different
from our own.

Surfing dolphins certainly seem
to be having fun.

DOLPHINS CLICK AND SQUEAK

Proving it is another matter.

To investigate what they're feeling,
a new spy will join them.

Spy Dolphin will be surfing with the best.

It not only swims like a dolphin

extra thrust helps
power it through the waves.

But can it surf with the best?

DOLPHINS SQUEAK AND CLICK

Dolphins are famed for their intelligence,
but how they feel may be just as important.

To find out more,
Spy Dolphin will join them in the waves

its camera eye capturing what they
experience.

Not bad for the first attempt.

Dolphins will play like this for hours.

For our spy, a chance for another go.

A wipe out!

Well, they say practice does make perfect.

And there's always another wave.

Like human surfers,
dolphins wait for the big one.

And like us, surfing is a communal event.

By playing and having fun
they learn social skills

and get to know what others are feeling.

Like any surfer,
they wait for the perfect wave...

and catch it just before it breaks...

For Spy Dolphin, a chance to try again.

For real dolphins, a chance for some tricks.

What dolphins feel when surfing
may not be far from what we feel.

When we surf,
we feel a surge of endorphins

feel—good hormones found in other animals...

including dolphins.

Endorphins change the mood for the better.

They help build friendships too.

And What could be better
than surfing with friends?

No longer a newbie,
our spy is now a surfing pro.

But it takes a real dolphin
to experience the joy.

French Polynesia is the next destination
for our surf—loving spy.

This time, he's investigating
the emotional life of humpback whales.

Each Winter, they travel over 3000 miles

from Antarctica
to reach these warmer waters.

They come to this safe haven
to find a mate or nurse their young.

But this is a humpback like no other...

one that can film.

Together they'll investigate
the playful nature of young whales.

A lively duo on a mission.

They needn't wait long.

A calf just two months old.

This is how a whale calf plays.

To find out more,
our spy must make its acquaintance.

Whales are inquisitive,
their young the most curious of all.

WHALE SONG

He certainly seems welcoming.

A promising sign.

Just when the encounter seems over

it comes back for more.

Again, another close pass...

ending with a playful swish of his tail.

Play is an important part
of a young calf's life.

So what will happen
when he meets Spy Whale?

A spy creature his own size.

Already, the calf is reacting differently.

His approach is slower...

and he rubs alongside,
as he would another calf.

He also shows off
by rolling and flashing his belly.

Slapping his fins is
an invitation to join in.

Twisting and rolling suggests
he wants more than to play...

he wants to be friends.

Adults make the same welcoming gestures.

Through play, he learns the skills
he'll need later in life.

WHALE SONG CONTINUES

Then, as quickly as it started,
introductions are over.

But there's plenty more
for our spies to see.

Spy Whale captures the moment
the calf's mother returns.

WHALE CLICKS ECHO

He dives down to greet her.

After all that play,
perhaps the strongest emotion of all...

a love between a mother and her young.

WHALE SONG

It's this deep connection
that will keep the calf safe

on their long journey back to Antarctica.

Off the coast of Australia,
there are more emotions to explore.

Giant cuttiefish are never ones
to hide their feelings.

In fact, they're clear for all to see.

Their ever—changing moods
are displayed on their skin.

To find out more, a doppelganger
has infiltrated the gathering...

One of the most sophisticated
spies ever made.

Its back conceals a screen

that can replay the patterns
expressed by the cuttiefish.

How will this imposter be received?

It's already attracting attention.

The skin of the cuttiefish
shows his emotional state.

Linked to his brain, thousands
of pigment cells expand and contract.

These chromatophores
show what's on his mind.

Our spy's screen responds in kind...

playing the patterns displayed by males.

A first contact with an alien mind.

He turns to check if rivals are watching.

As he does,
the patterns switch to his other side

the one that faces our spy.

Then a clue to what he's feeling.

He approaches our spy from the side.

It's something he'd only do to another male.

It seems our spy is displaying
a provocative message...

that of a rival male.

By approaching from the side,
he avoids the maie's sharp mouthparts.

But as our spy isn't aggressive,
the cuttiefish is intrigued.

It then changes its display
to the more neutral patterns of a female.

The male is even more curious.

In female guise, our spy gets
a very different reaction.

He now dares approach from the front...

a sure sign he knows he's not with a male.

But a female cuttiefish attracts
many admirers...

ones he must keep at bay.

He returns to our spy.

A unique relationship
has been formed...

one that will reveal more
about the emotional lives

of these extraordinary creatures.

Cuttlefish aren't the only sea creatures

to wear their feelings on their skin.

The colours of octopus
also change with their moods.

Spy Octopus couldn't possibly compete

but it may find someone who can.

Mimic octopus are
the tricksters of the ocean.

They not only change their skin colour
with their emotional state...

they change to match their surroundings too.

But our spy discovers
that's just the start...

it even recreates the grains of sand...

raising its skin to match the texture.

That's not all.

Among seagrass, he'll even mirror
its shape and movement.

A trick to fool his enemies.

But as impersonations go,
he'sjust warming up.

For his next trick, he needs inspiration.

Hidden in the sand
is another vanishing act...

a poisonous flatfish.

Impersonate this,
and he can avoid being eaten.

Not bad at all.

But will it fool the real thing?

By staying in character,
the mimic has gained an admirer.

The flatfish is looking for a mate.

This relationship is dead in the water...

but he has plenty more tricks to pull.

Constantly changing persona
confuses predators.

New inspiration is never far away.

The deadlier the better.

A lionfish, armed with 18 venomous spines.

But is he up for the challenge?

He'll certainly give it a go.

He flattens his tentacles
to mimic the lionfish spines.

And changes his shape and colour too.

Enough to fool an enemy.

But it's not the end of his repertoire.

Sea snakes are among
the world's most venomous snakes.

Even though they're surprisingly docile

their banded appearance
still keeps danger away.

It's certainly worth mimicking.

So far, over 15 different impersonations
have been discovered.

But has he another to add to the list?

A passable imitation of our very own spy.

SEALS GRUNT IN DISTANCE
— SEABIRDS CRY

In New Zealand, it's an emotional time
for a colony of fur seals.

The pups are three months old
and they've just left their mother's side.

Their playground is a rockpool,
safe from the ocean waves.

At this sensitive time,
Spy Seal is here

to find out what they might be feeling.

Like us, their emotions are influenced
by hormones

the same as those
that govern our own feelings.

Spy Seal watches
as they learn the social skills

that will help them later in life.

But not all are ready for playschool.

This pup is a few weeks behind the others.

He's yet to leave his mother's side.

But that's about to change.

The fear of missing out
makes him want to join the other pups.

His first tentative steps
towards independence.

It's the sign his mother was waiting for.

She slips away unseen.

He'll be left alone for days.

It's a worrying time...

SEAL GRUNTS
— He's never felt loneliness before.

But Spy Pup is near and welcoming.

A comfort for a pup whose mother has gone.

His next step is to join the playgroup.

First, he must summon up the courage.

As the youngest pup,
he's the most vulnerable

and the weather
is changing for the worse.

Our spy is first to feel its force...

and this is just the start.

Those more experienced
head to the shore.

SPY SEAL WAILS

But the young pup has yet
to learn the dangers.

He's now at the mercy of the waves.

He's not the only one.

Spy Seal joins him in the surf

But waves wash both ways...

and the pup makes it out as well.

But his playmates have abandoned
the beaches to head inland.

He'll struggle to catch up with them now.

They're heading upstream
for somewhere safer to play.

He's alone once more.

Although not completely alone.

SPY SEAL BARKS

A companion to raise his spirits.

SEAL SNIFFS AND BARKS

But it's the real pups he needs to find.

Where he's going, our spy can't follow.

The pup will struggle on alone.

To cover the challenges he faces,
rock cams take over filming duties.

They're hidden all along the way.

SEAL GRUNTS

SEAL CRIES

The pup won't be daunted...

despite facing one hurdle after another.

The first trial is over

but his emotions will soon
be tested once more.

The feelings we share with other life
are found among all marine mammals.

Including a visitor to the coral reefs
of the Caribbean.

A manatee.

They come here purely to socialise

It's somewhere where friends
and acquaintances can meet.

A very special visitor
is about to join them...

a spy creature seeking company.

But what will the real manatee think?

It's clear he's curious.

Spies based on youngsters
usually go down well.

Inspection over,
Spy Manatee is off to a good start.

The manatees' closest
living relatives are elephants.

It appears they share
their emotional side too.

Our spy soon finds out
how affectionate they really are.

MANATEE SQUEAKS

Mouths formed to graze on seagrass

here offer a gentle caress...

and even a slobbery kiss.

Why they enjoy these touchy—feely
moments soon becomes clear.

Hairs that cover their body
are highly sensitive to touch.

Who they groom and for how long

depends on the strength
of their relationships...

whether they are close friends
or looking for a mate.

Often they enjoy just hanging out together.

When socialising's over, they go up a gear.

For a youngster, a game of chase...

but the manatee's favourite pastime
is just chilling out.

When our spy does the same,
it attracts attention again.

This time it receives
an affectionate once—over...

and even a manatee kiss.

It's the ultimate sign of acceptance.

Just what we wish of our spy.

Back in Australia, emotions are
still running high among the cuttiefish.

As before, our spy is being guarded
by the jealous male.

It's still displaying
the subdued patterns of a female...

but in the breeding season,
many other males are also looking for a mate.

It's a full—time job, keeping them at bay.

But some are ready to take him on,
carefully avoiding his sharp mouthparts.

Eight arms soon toss him away.

But he comes back for more...

and is dealt with just as decisively.

The male returns to our spy.

To calm things down,
it switches its display to that of a male.

It took him by surprise

giving our spy the chance
to leave him to it.

The cuttiefish are left fighting it out
among themselves.

Even they have testosterone

the hormone that charges
our own aggression.

Across the reef, tensions are rising.

Wherever our spy goes, it finds females
jealously guarded by males.

The cuttiefish hides her
beneath his flowing mantle...

always just out of view.

But she's a reluctant partner,
and tries to get away.

By squirting ink,
she creates a cloud of confusion.

She escapes unseen.

With so much rivalry

the cuttiefish
find crafty ways to come out on top.

Younger, smaller males use a sneaky trick.

Male tentacles are longer than females

so he tucks them away to disguise his sex.

His skin patterns also
mimic those of a female.

In this way, he sneaks in unnoticed
to fool the dominant males.

As they fight it out,
the imposter hovers on the sidelines...

waiting for his chance.

When the female wriggles free,
his moment arrives.

Just what he was hoping for.

He makes his move...

slinking past the bigger male...

and stealing his female.

It's a kidnap in plain sight.

Beneath their embrace,
he gives her a present to fertilise her eggs.

A spermatophore she'll keep for later.

But the female can be sneaky too.

She'll mate with others and keep
their gifts of sperm as well.

She will choose which she'll use
to father the next generation.

Among cuttiefish,
it seems all's fair in love and war.

Everywhere, courtship is a time of heightened emotions.

The tidal mudflats are the mating grounds

of some very odd fish...

ones that spend most of their lives on land.

This fish out of water is
a blue—spotted mudskipper.

He breathes by gulping air and absorbing oxygen through his mouth.

By keeping wet,
he can even breathe through his skin.

He certainly needs the oxygen.

His courtship rituals are
as bizarre as his looks.

It takes a very special spy to film them.

Mud is an occupational hazard

so its camera has a built—in lens cap.

As the day warms, it spies a female
venturing from her burrow.

She's on the lookout for an eligible partner.

The bigger the better.

Our spy fits the bill.

Waving her fin like a flag
is another good sign.

Our spy waves back.

But this is Where it all goes wrong.

There are plenty more males to choose from.

Spy Mudskipper has serious competition...

and their flag—waving is far more seductive.

But to really impress,
flagging alone is not enough.

He must show what else he can do.

As emotions soar, it's now a competition.

There's one yet to have a go.

Hardly a serious contender!

She's after the one that leaps the highest.

She approaches the two best contestants.

Our spy is cast aside.

There can only be one winner.

To decide, they must fight it out
among themselves.

The female awaits the result.

Finally, the loser is driven away.

She has her champion.

He leads her back to his burrow.

They'll spend the season together
in his underground mud nest.

Our Spy's flagging performance

was no match for the high—flying males.

While mudskippers are
not short of passion

some creatures are prepared to swim
thousands of miles to find a mate.

ln Costa Rica,
olive ridley turtles are returning

to the beaches where they were born,
to lay their eggs.

But first, they need to be fertilised.

A job for the males.

Among them is Spy Turtle...

ready to take a closer look.

Then, what our spy came to see...

a pair of mating turtles.

The female travelled
over a thousand miles to get here

so she makes sure the journey was worth it.

Her current partner is the first of many.

To improve his chance of success,
claws on his flippers

help him hang on for several hours.

But While he's on board,
the female is firmly in control.

She's making a beeline for our spy.

It valiantly keeps filming

while the male does his best to hang on.

She strokes its face to show her interest.

But Spy Turtle has a job to do...

and so do the turtles.

For a spy seeking the emotionally aware,
there's always more to discover.

A pod of bottlenose dolphins has arrived.

DOLPHINS CLICK AND SQUEAK

They give our spy the once—over.

Dolphins not only know
how to enjoy themselves

they also form strong emotional
attachments to each other.

Pod members may come and go,
but most form enduring friendships.

The relationships
between them are strengthened

by touching and even tickling each other.

There's even
a dolphin's version of cuddling.

DOLPHINS SQUEAK

But of all of them,
a newborn baby gets the most attention.

At five days old

he still bares wrinkles
from his time curled up in the womb.

For the first few weeks of life,
he never leaves his mother's side.

To keep him safe, she must
change her way of life completely.

As she can stay down for 15 minutes,
and he must breathe every two

for the first few weeks of life,
she must keep him close to the surface.

She'll care for him as only a mother can

while teaching him the ways of the dolphins.

Of all the emotional bonds
our spies have found

the strongest of all
is between a mother and her offspring.

But in New Zealand

there's still one lost baby
far from his mother.

Spy Albatross is tracking the path
of the lonesome seal pup.

It follows the mountain stream
the pup was left climbing.

His destination
is a waterfall high in the hills...

but the pup is still trying to reach it.

He tries to press on...

but it doesn't get any easier...

and the journey so far has taken its toll.

He's dispirited and exhausted...

but once more, he's not alone.

SEAL GRUNTS

Spy Seal invites him to play...

and has the perfect plaything.

SEAL SNORTS

SEAL CHIRPS

How better to improve his mood?

Play releases endorphins,
just as it does with dolphins.

SPY SEAL BARKS

It's just the boost he needs.

SEAL BARKS

But he still has one last hurdle to climb.

Then finally,
what all the climbing was for...

A lagoon filled
with the pups that went before.

His quest is finally over.

All he needs do is take the plunge.

Here, he can play
without a care in the world.

But has he forgotten someone?

His companion and playmate...

with a new toy to play with.

One to be shared with everyone.

But there's still one who's missing out...

a spy that's now a friend.

With some encouragement,
it too takes the plunge.

With a full team, the games begin again.

Passing the stick is
a lesson in working together...

vital when hunting fish shoals as a team.

It also builds strength
for life in the ocean.

The pup will enjoy this mountain paradise
for a week or so

before returning to the sea.

He's had an emotional journey to get here

but he's now better equipped
for adult life.

By befriending our spy

the pup gave us insights
into his inner feelings.

Whoever he meets in the future

he'll never make a friend
quite like his first friend.

Next time, our spies will discover

the extraordinary relationships found
throughout the oceans...

and how working together is always the better way.
