All language subtitles for Spy in the Ocean S01E03 Deep Relationships

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.
DOLPHIN WHISTLES

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.

On our spies' latest mission,

they reveal the extraordinary
relationships that exist

among the creatures of the ocean.

In Australia,
an astonishing event is under way.

Cued by the full moon, spider crabs
rise up from the abyss deep below.

To reveal what's going on,
Spy Crab joins the march.

Eight robotic legs
give the traction it needs.

Like the real thing, a hard shell
protects its innards.

In this case, a camera.

Over the next two weeks,
thousands upon thousands

of these usually solitary creatures
will gather.

Then a hint at why they're here.

Spy Crab discovers that some
are emerging from their shell.

Squeezing out can take
15 minutes or more.

Enzymes oil the process,
helping her slip away.

Freed from what's become a prison,

she now has space to grow.

Her new shell will take weeks
to harden.

Until then, she'll hide among
the better protected.

For now, she'll make do
with our spy.

She has good reason to hide away.

There are plenty out to get her.

A four-metre stingray
can eat 50 crabs a day.

They hoover up any
who've lost their shell.

Our spy becomes the crab's defender.

The ray will look
for an easier meal.

Those with hard shells
aren't worth the trouble.

Males even stand and fight.

Those with soft shells
hide among the hordes.

Despite their brave defenders,
the ray can hunt them down.

It makes short work
of extracting meat from shell.

The crab-in-hiding
makes her getaway.

She needs to get lost in the crowd.

The ray's victim
is now an empty husk.

But he's yet to have his 50 a day.

And the fleeing crab
is still in the open.

She's made it.

Now to vanish among the masses.

The greater the numbers,
the harder it is for the ray.

Those with hard shells
form an armoured fortress,

with the soft-shelled
hidden beneath.

Left in the open, Spy Crab
is now a sitting target.

It gets the full
death-ray treatment.

A crab's eye view
of an untimely end.

But it's still live and kicking.

It's not over yet.

This time the ray did it a favour.

Back firmly on its own eight feet,
our spy heads to the fortress.

It has a tower of crustaceans
to climb.

But there's no need.

The crabs come to our spy.

They create a shield
of legs and armour.

A living citadel built on sand.

A brief monument
to the strength of teamwork.

Many sea creatures have found
value in being together.

Sharks may have a reputation
as solitary killers,

but many are surprisingly social.

Scalloped hammerheads are among
the most sociable of all.

They travel in their hundreds
as they head to a remote island

300 miles off the Colombian coast.

Today they have a spy
in their midst.

A mechanical marvel,
propelled by its shark-like tail.

It hardly makes a sound.

Vital when filming these
surprisingly shy creatures.

As well as a camera in each eye,

it has another in its fin.

One with 360 vision.

It can even film through its jaws.

Our spy has much to reveal.

Most are female, with the largest in
the middle and the smallest outside.

Some even choose a travel companion
for their journey.

When they reach the island,
they linger for a while.

Malpelo is a magnetic anomaly.

A place where the Earth's
magnetic field

is distorted by the rocks below.

Hammerheads use the magnetic field
as a compass,

so this place has unseen
significance.

They gather here, having returned
from their feeding grounds.

They are met by a surprising
welcoming party.

King angelfish that provide
a personal grooming service

to these would-be killers.

Wounds are attended to
and parasites removed.

As hammerheads feed
in the deep ocean,

the angelfish here are safe.

While they get a meal,
the sharks enjoy a makeover.

In this topsy-turvy world,

fish seem to like sharks so much
even our spy gains a following.

Galapagos sharks also visit
this undersea spa

and receive the same warm welcome.

Pilot fish cluster around the
shark's jaws but are never taken.

Instead, they benefit
from the shark's protection.

In return, they clean its teeth
and gain a meal in the bargain.

Rainbow chub are also shark-lovers.

They rub themselves on
the shark's serrated scales.

A trick thought to scrape off
parasites.

In this place of apparent harmony,

other intriguing relationships
can be found.

Spy Moray Eel joins the team.

Like the real thing,
it moves silently.

Its mechanical spine creates
the waves that propel its body.

This is what it came to see.

A community of moray eels.

Despite their ghoulish looks
and razor-sharp teeth,

they live in relative harmony.

Spy Moray is here to study
the partnership they share.

Their unlikely allies
are leather bass groupers.

Our robotic moray soon attracts
their attention.

For the fish are here
to wake up the eels.

Their snooze alarm
could hardly be gentler.

But, one by one, they stir.

The groupers signal
it's time to follow.

With more gentle encouragement,
the eels oblige.

To discover the reason,
Spy Moray follows behind.

They're heading to a spot
the fish have checked out before.

A place where smaller fish
are hiding.

A headstand marks the spot.

A signal to the eels.

They slink in where groupers can't

and flush out the fish.

There's one!

Then another!

And another!

Most are too quick to catch.

But in the scrum, there's enough
for both groupers and eels.

Despite the ones that get away.

It's the prefect relationship,
where both gain.

But Spy Moray is experiencing
a technical malfunction.

WHIRRING NOISE

A loss of transmission.

But still keeps filming.

The groupers act as if our spy
is part of the hunt...

..and has found something.

Soon our spy
is completely smothered.

But help has arrived.

A spy to shepherd them away.

The signal finally gets through.

Like others in this
undersea community,

our spies use teamwork too.

In the oceans, working in
partnership is surprisingly common.

For bottlenose dolphins
it's a way of life.

To strengthen the bonds
between them,

they spend a lot of time at play.

To find out who else
might join their games,

Spy Pelican follows from above.

While Spy Dolphin films from below.

DOLPHINS WHISTLE

Together, our roving spy creatures
find a possible playmate.

A southern right whale.

A species not known for
its fun-loving lifestyle.

It will need some coaxing.

Something to get it in the mood.

Already it seems to be working.

Some show their belly -
a sign they want to play.

The whale even attempts a leap.

They have the playmate
they're after.

But who can compete with a dolphin?

There's no harm trying.

Another whale joins.

It's now double the fun.

DOLPHIN WHISTLES

Still more arrive.

But you can have too much
of a good thing.

Party over, the dolphins
take their cue to leave.

Spy Dolphin gives it one last go.

But it's not the same.

To discover that whales and dolphins
play together is a revelation.

For our spies, there are always
new surprises to uncover...

WHALE GRUNTS

..and more astonishing
relationships to find.

DOLPHINS WHISTLE AND CLICK

This pair of male dolphins
are of different species.

One is a bottlenose,
the other a rare humpback dolphin.

They were forced from their
family pod once they came of age.

Cast out and alone,
they found company in each other.

Now they go everywhere together.

A true bond between friends.

But despite their
close relationship,

they need to join a pod.

A gang of male dolphins
is just what they're looking for.

DOLPHINS WHISTLE AND CLICK

But these are bottlenose dolphins,
so the humpback must be cautious.

DOLPHIN CLICKS

His friend calls to the group -
a specific whistle unique to him.

DOLPHIN WHISTLES

The humpback follows
as close as he dare,

anxious not to lose his companion.

CLICKS AND WHISTLES

But pods are reluctant
to accept newcomers,

and never those
of a different species.

They drive the humpback away.

He won't be coming back.

LOUD CLICKS

The bottlenose must decide -

does he follow his buddy
or make new friends here?

For the bottlenose,
it's clear where his destiny lies.

It's not with the humpback dolphin.

But joining the pod won't be easy.

First he must show he'll fit in.

His ploy is to use the moves
more often made by females.

It seems to do the trick.

WHISTLING AND CLICKING

But now he faces
an initiation ceremony -

one all males must endure.

Some rough-housing to prove
he's a worthy member of the gang.

Over time he'll be accepted

and he's better in the pod
than outside.

For the humpback
it's a different story.

He'll roam the ocean alone
until he finds a pod of his own.

Even sociable creatures like
manatees can't always choose

who they mix with.

Spy Manatee is now fully accepted
into the group.

MANATEE SQUEALS

It's discovering that even here
they have friends they like,

and then there are the hangers on.

Latched onto her body
are remora fish.

Totally harmless, their relationship
is extraordinary.

They feed on skin flakes
and parasites

and whatever the manatee poos.

What was once a fin has evolved
into a suction pad on their head.

As well as food, the manatees
provide an energy-saving way

to get around while keeping water
flowing through their gills.

Those on top travel upside down.

If they move to the belly,
they're more easily shooed away.

Even so, there's always
another free ride.

While remora can be a nuisance,
sergeant major fish are welcomed.

Our spy investigates why
they're accepted so readily.

The fish provide a cleaning service.

They graze on the algae
that grows on the skin.

For a full body treatment,
manatees strike a pose,

letting the fish tackle
those hard-to-reach places.

It sends them into a state of bliss.

Until they nod off.

The spa is popular.
Everyone wants the full makeover.

But not all the fish here
are friendly.

Nurse sharks patrol the coral heads.

While stingrays search
the sandy seabed.

These predators could be
the ultimate test for our spy.

Rays and sharks can detect
electromagnetic signals.

Spy Manatee has plenty of those.

An exploratory nibble.

But there's nothing here
to be found.

Like most of our spies,
Spy Manatee attracts the curious

rather than the aggressive.

In Indonesia, Spy Hammerhead
continues its own

journey of discovery.

It soon finds that across the ocean,

similar partnerships have evolved.

Here it's cleaner wrasse
that take on cleaning duties.

They even act as dental hygienists.

With trapped food the reward.

But these pearly whites
have nothing to offer.

An olive sea snake
shows his inquisitive side.

He's one of the most
venomous snakes in the world.

Today he's on the hunt.

He can hold his breath
for up to two hours.

Useful when searching for a meal.

He's after the fish
that hide in the coral.

To catch them he needs help.

And on the reef,
support is rarely far away.

A female who's also hunting.

Like moray eels, the snakes have
formed a partnership with a fish.

But here it's trevally
who know where food can be found.

All the snakes need to do
is follow them.

When they arrive, the trevally
show them where to look.

Like moray eels,
snakes can go where others can't.

But these snakes have a problem.

They aren't the only ones hunting.

Soon there are too many
after the same meal.

The snakes and trevally
grab what they can.

But there's a limited supply.

And more hungry snakes keep coming.

This partnership works best
with fewer numbers.

Today, there are not enough
fish to go around.

But the snake couple
won't go unrewarded.

It's now a relationship
of a more amorous kind.

They head to the surface...

..joining together
in a serpentine embrace.

One that forms a fitting symbol.

Together they descend
to the reef below.

They'll stay entwined
for up to an hour

before going their separate ways.

Of all the relationships
found in the ocean,

few can beat the spinner dolphins.

As well as gathering
in huge numbers,

they are the acrobats
of the dolphin world.

They can leap over three metres high
and spin seven times in a jump.

Today, they're on
a hunting expedition.

Spy Dolphin is here to find out
how they work as a team.

WHISTLES AND CLICKS

Their bubbles provide a clue.

On closer inspection, they plainly
come from the dolphin's blowholes.

DOLPHINS WHISTLE

A sign they are whistling
to each other.

They use these calls
to bring the pod together.

They also have a unique whistle
to announce who they are.

The dolphin equivalent of a name.

As well as whistles,
they use clicks to communicate too.

Some clicks are ultrasonic -
far above our hearing range.

All this works at close range,

but to contact dolphins far away
they use their corkscrew leaping.

For an aerial view
of what's going on,

Spy Frigate films from above.

The leaps can be seen
by distant dolphins.

While the splashing can be heard
from far and wide.

All these cues bring
the dolphins together.

United, they can hunt
as a super team.

Our spy is in the midst
of an extraordinary gathering.

One of the greatest mega pods
ever filmed.

Spy Dolphin is here to witness
this astonishing moment.

And there's yet more to discover.

Yellowfin tuna also heard
the dolphins

and join their quest for a meal.

As both dolphins and tuna
travel together,

the ocean becomes a superhighway.

Above, frigate birds
join the travellers,

including our spy version.

As they near their goal,
the dolphins leap into action.

A synchronised wave,
thousands strong.

Spy Frigate records the moment
they close in on their target.

They've found a fish shoal
of an unexpected kind.

A squadron of flying fish.

Chased into the air
by the hunting dolphins...

..the tuna even try to grab them
as they fly.

With dolphins and tuna working
together, few escape.

The frigates, too,
take what they can.

An event made possible
by extraordinary teamwork.

As the day ends,
they have reason to celebrate,

and they do it in true
dolphin style.

Off Mexico, shoals of mackerel
are gathering too.

Upwellings of nutrients
have caused plankton to bloom.

It's not only mackerel
that relish the feast.

A tuna crab.

A type of squat lobster.

It won't be alone for long.

More are rising from the depths.

As always, there's a spy
for every occasion.

With a subject worthy
of special attention.

Tuna crabs only come together
when conditions are perfect.

They may all look the same
but they are not short of character.

A blade of sea grass
becomes something to fight over.

It's now a tug-of-war...

..with both a winner and a loser.

Spy Tuna Crab arrived
at a special moment.

An event that has rarely
been filmed.

Hundreds soon become thousands.

Then thousands become millions.

They devour all the plankton
they can.

When they've had their fill,
they descend to the deep once more.

Those that leave are soon replaced

and so the cycle goes on.

Such numbers have seldom been seen.

A magical moment before they vanish
into the depths once more.

When autumn brings storms
to the Caribbean,

another gathering begins.

Spiny lobsters leave their hideaways
and start to assemble.

They're preparing to migrate
to calmer and warmer waters.

One has yet to join them.

Another spy.

As the storm builds,
conditions worsen.

Alone, they're vulnerable,

not just to currents
but predators, too.

So they'll make their journey
together.

Already, Spy Lobster has company.

Others also couple up.

Everyone joins the great migration.

Including our spy
and its new-found buddy.

As the lobsters come together,

it becomes a game
of follow the leader.

Latecomers race to join.

Including our spy.

A chain soon starts to form.

It becomes a lobster conga,

their antennae keeping each in line.

The members can number 50 or more.

No-one wants to be left behind.

As they head for deeper water,

walking in line reduces drag
and keeps them on course.

Guided by the Earth's
magnetic field,

they can march like this for days.

Already they are vanishing
into the deep.

Leaving Spy Lobster far behind.

Shipwrecks are testament
to the power of the storms.

They are now a refuge for those
sheltering from the turmoil above.

Another place, another spy.

This time, Spy Nautilus.

It finds that every nook
and cranny is occupied.

With little shelter elsewhere,

the wreck is a magnet
for the vulnerable.

Spy Lobster joins the search.

Then, a promising sign.

Two lobsters hiding
beneath the broken bow.

They're not the only ones.

In every crevice, more can be found.

With no claws to protect them,
wrecks like this keep them safe.

For them, the journey
has been worth it.

Here they'll spend the winter,

until the shallows warm once more.

There is one place our spies
have yet to visit.

The islands of the Galapagos
are home to a rich community

of sea creatures.

On the volcanic rocks
that hug the coastline,

marine iguanas bask
in the morning sun.

It's a time to socialise as
they warm up for the day ahead.

Among the masses is a visitor
from outside.

A spy adapted to both land and sea.

It needs both talents
for iguanas feed on vegetation

and the land has little to offer.

Once they're up to temperature,
they take the plunge.

Where they go, our spy must follow.

Iguanas are coldblooded,
so their time in the cold sea

is limited to just half an hour.

That includes battling the surf.

Spy Iguana swims
just like the real thing,

propelled by its articulated tail.

When an iguana dives,
our spy dives, too.

The best feeding grounds
lie deep beneath the waves.

Our spy will join them there.

Unlike the barren land,
the sea is rich in nutrients.

It nourishes the algae
the iguanas depend on.

They eat little else.

Each has chosen a spot to graze.

Spy Iguana hardly causes a stir.

There's no rivalry here.

But the real iguanas
are on borrowed time.

He must eat what he can,
while he can.

Leave it too late and he'll be
too cold to make it back.

But he knows when his time is up.

He heads to the surface
and returns to land.

Our spy has many other
inhabitants to meet.

The most playful of all
are Galapagos sealions.

And who better to play with
than our spy creature?

But playing games is not
in our spy's repertoire.

No matter the encouragement
it receives.

The sealion seeks a more
playful partner.

But he leaves Spy Iguana
in the best possible spot,

just in time to meet
a true wonder of the deep.

Mola mola - a type of sunfish.

Its only means of propulsion
are its elongated fins.

One of the largest bony fish
in the ocean,

it reaches three metres in length.

They visit for one reason only.

To be cleaned by angelfish
and hogfish.

As our spies have found,

almost all undersea communities
have their own grooming specialists.

Job done, they return
to the deep blue yonder.

Our spy has one last
inhabitant to find.

The shallows are home to
a colony of damselfish.

They are suspicious of outsiders.

They're keen gardeners,
so trespassers aren't welcome here.

DAMSELFISH CHIRPS

They spend their time
tending their lawns of algae.

Like an allotment,
it's divided into plots.

To attract a mate, each male
has his own patch to care for.

They must beware of intruders.

A sea urchin, looking uncannily
like a naval mine.

CHIRPING

It creates its own kind
of devastation.

It will graze their precious algae
down to the rock.

To remove it,
they must work together.

And use a bit of extra oomph.

It's now out of his patch
and onto his neighbour's.

Each damselfish passes it
to the next fish along.

They'll persevere
until it's finally gone.

Nearly there.

Done it!

But our spies' adventures
aren't over.

Spy Hammerhead has arrived
in the Galapagos,

along with the hammerheads
last seen off Colombia.

The sharks are completing
a round trip

that began in the seas
around these islands.

Hammerheads, like other
long distance travellers,

connect distant communities.

A network of partnerships
that reach across the globe.

As our spies have found,

ocean life is interconnected
in ways we could hardly imagine.

An undersea world built on
extraordinary relationships.

Next time, we discover some of
the trouble sea creatures face.

And what happens
when things go horribly wrong.
