All language subtitles for Spy in the Ocean S01E02 Deep Feelings

The world's oceans are full
of wonder.

An alien world waiting
to be explored.

A place of extraordinary
life forms

with intriguing social lives...

..and incredible intelligence.

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.

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 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.

DOLPHINS WHISTLE

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...

..at the point of maximum power.

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
3,000 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.

WHALE MOANS

SPY DOLPHIN WHISTLES

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

Whales are inquisitive,

their young the most curious of all.

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 BELLOWS AND SQUEAKS

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 GRUNTS

He dives down to greet her.

After all that play,

perhaps the strongest emotion
of all -

the love between a mother
and her young.

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 cuttlefish 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 cuttlefish.

How will this impostor be received?

It's already attracting attention.

The skin of the cuttlefish
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 male's
sharp mouthparts.

But as our spy isn't aggressive,
the cuttlefish 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 cuttlefish
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 sea grass, he'll even mirror
its shape and movement.

A trick to fool his enemies.

But as impersonations go,
he's just 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.

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.

SEALS HONK

Their playground is a rock pool,
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.

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 MOANS

But the young pup is 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.

SEAL BARKS

Although not completely alone.

SPY SEAL CALLS

A companion to raise his spirits.

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,

rockcams take over filming duties.

They're hidden all along the way.

SEAL YELPS

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,

having spent most of their day
out feeding.

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 manatee's closest living
relatives are elephants.

It appears they share their
emotional side, too.

Our spy soon finds out
how affectionate

they really are.

MANATEE SQUEALS

Mouths formed to graze on sea grass

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're 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 cuttlefish.

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 cuttlefish 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 cuttlefish 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 cuttlefish
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 impostor
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 cuttlefish, it seems all's
fair in love and war.

Everywhere, courtship is a time
of heightened emotions.

The tidal mudflats of Japan
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.

MUDSKIPPER GASPS

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.

In 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 1,000
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.

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.

DOLPHINS CLICK

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

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 HONKS

Spy Seal invites him to play...

..and has the perfect plaything.

How better to improve his mood?

Play releases endorphins,

just as it does with dolphins.

It's just the boost he needs.

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.

Reunited with the pups he last saw
in the ocean...

..here he can play without
a care in the world.

But has he forgotten someone?

His companion and playmate...

SEAL BARKS
..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.
