The animal world is full
of spectacle and wonder.

But what's it like to be right
in the heart of the action?

To find out, our team of spy
creatures goes undercover.

They not only look like the animals
they film...

..they behave like them, too.

Armed with the latest camera
technology...

..they are heading across the globe.

From the heat of the tropics...

..to the lands that lie
in the north.

From the islands
of the Southern Seas...

..to the snow and ice
of the frozen poles...

..our spies reveal the astonishing
variety of life that thrives there

from inside their world.

On this assignment,
our spy creatures

reveal how life thrives on the
islands of the Southern Hemisphere.

Far from the mainland,

these isolated places

have given rise to some of the most
unique animals on Earth.

The Galapagos Islands
of the Pacific Ocean.

A barren archipelago

formed by underwater volcanoes

over three million years ago.

This landscape of lava is home

to a remarkable fauna

found nowhere else in the world.

One of the most intriguing

is the marine iguana.

Before they can become active,

these cold-blooded lizards

must bask in the sun.

Their black skin absorbs the heat,

raising their core temperature

to a toasty 40 degrees.

To film these
highly protected animals,

Spy Iguana has special permission

to go closer
than any human is allowed.

To succeed, it has to be totally
convincing.

Once they are hot enough,

they start to move.

Spy Iguana

now witnesses something remarkable.

Cliff jumping for lizards.

They are after the seaweed

that flourishes just off shore.

They're on borrowed time.

The water's cold.

And in less than an hour,

their body temperature will halve

and they'll have to return.

Now, another spy takes over.

Lava Cam can track the iguanas

wherever they go.

At this time of year, the females

are laying their eggs on the beach.

The sand is baking hard,

but a metre down

it's the perfect temperature
for incubation.

Spy Iguana joins them

for a closer look.

Digging the nest can take an hour.

Hard work in the hot sun.

When they take a break,

they have a self-styled sun hat.

Even our spy.

Competition for the best nest sites
is intense.

Those digging must be prepared
to hold their ground.

Head bobbing is a challenge
for ownership.

The winner is decided

by a test of strength.

The owner wins.

She's free to finish her work.

Along the tide line,

the others are returning

from their underwater feast.

Chilled through by the cold sea,

they must sunbathe once more.

As Spy Iguana joins them,

another surprise is in store.

They sneeze snot.

Special glands in their nose

remove excess salt,

which is expelled spectacularly.

Whatever they can do,

our spies can do, too.

Oh...perhaps not.

As the day ends,

iguanas show their more
affectionate side.

Even our spy has an admirer.

Snuggling together

preserves precious warmth,

as the sun sets

over the Galapagos Islands.

Over 8,000 miles away,

off the southern coast of Australia,

Kangaroo Island is another
unique wildlife haven.

Cut off from the mainland

for 10,000 years,

it even has its own variety
of kangaroo.

Koalas are here, too.

But they are relative newcomers.

Introduced here 100 years ago,

they now survive

in unrivalled numbers.

Among them is a new koala,

fresh from the mainland.

It's here to film

their breeding behaviour.

The timing's perfect.

They're just waking up.

Yawning pumps oxygen to the brain.

Even wide awake,

he needn't go far.

His favourite food
is all around him.

Eucalyptus.

But their leaves are not only tough,

they are poisonous,

so koalas have
powerful digestive juices

that neutralise the toxins.

Just digesting their food
saps energy,

so they sleep up to 23 hours a day.

But today, this koala

is breaking the habit.

In the breeding season,

he must step up a gear.

One of our mobile spy cams

must rise to the challenge.

Koalas rarely come to the ground

or show such a turn of speed.

But he now has a territory
to defend.

KOALA BELLOWS

He bellows to announce
he's in charge.

A warning to other males.

HE BELLOWS

Koalas scent mark the ground

to tell each other who's been
passing through.

He's caught the scent of a female.

But this one already has a baby.

No point chasing her.

But she's not the only female here.

And our spy is now keeping
her company.

The male's enthusiasm
may be short-lived.

A rival has found her first.

He will have to
challenge for possession.

HE BELLOWS

He announces his arrival

with a warning.

HE BELLOWS

Spy Koala is witnessing

something rarely filmed.

A fight in the treetops.

SCREECHING

The only injury...

..a loss of dignity.

The loser makes his retreat.

While the challenger gets the girl.

For all, that's quite enough
activity for one day.

Christmas Island
in the Indian Ocean.

Home to a creature

found almost nowhere else on Earth.

Every year, the monsoon rains

sweep the island

and trigger a mass awakening.

Spy Crab is ready to capture

what's about to unfold.

The real crabs have been sealed

in their burrows for months,

avoiding the worst

of the yearly drought.

Now they emerge en masse.

Each female carries thousands

of eggs in a protective pouch

beneath her belly.

United by a common goal,

they begin their march to the sea.

A few soon become an army.

They haven't eaten for months

and are hungry for anything
they can find.

Sometimes even each other.

But a robotic crab

won't satisfy anyone's hunger.

All in working order,

Spy Crab rejoins
the march to the sea.

Since human settlers arrived,

the crabs have faced hurdles

never found in nature.

The smallest try to squeeze through.

The rest have just one option.

To climb.

No problem with
six powerful legs to help.

Once down, an even greater
challenge awaits them.

Many roads close in
the migration season, but not all.

There are always some

that never make it.

But here it's a case

of waste not, want not.

Now it's Spy Crab's turn.

Against the odds,

most make it to the coast.

They assemble in the shade,

waiting for the perfect moment.

High tide triggers the final push.

Then, in their thousands,

they release their eggs.

A victory dance speeds the process.

Each crab may release 100,000 eggs,

all swept out

by the retreating tide.

In four weeks' time,

their hatchlings will return
to the island.

Madagascar.

Bizarre baobab trees

are a remnant of the island's

ancient connection to Africa,

now 300 miles west.

It was once connected to Asia, too.

Separated from both

for millions of years,

life here has taken

its own evolutionary course.

In the island's spiny forest,

95% of plants

exist nowhere else on Earth.

And the animals are equally unique.

A sifaka lemur.

One of over 100 different species

found only here.

Madagascar is also home to half
the world's species of chameleon.

One of the most beautiful

is the panther chameleon.

This one's a spy.

He's eyeing up a warty chameleon.

To their own kind,

they are fiercely territorial.

But not, it seems, to our spy.

While our chameleon
is otherwise preoccupied,

another takes over.

It's soon spotted by another lemur.

The ringtail.

They spend more time on the ground

than any other.

They're also
intelligent and curious.

Anything new demands a second look.

Lemurs are sun-worshippers.

Adopting the lotus position

helps raise their body temperature.

Vital for an animal

with a low metabolism.

They're very good natured -

even to those that steal their sun.

After half an hour's meditation,

the day begins.

They live in large groups

up to 30 strong.

Their tail acts as a flag,

making sure no-one gets lost.

While ringtails spend

most of their time on the ground...

..sifakas spent most of theirs

in the trees.

Their powerful legs

and stabilising tails

help them leap up to ten metres.

Adapted for jumping

from tree to tree,

they have trouble

walking on all fours.

They have a unique solution.

They pogo.

How better to cross open ground?

It may not be conventional,

but it's surprisingly quick.

In just a few seconds,

they can be gone.

Leaving our spy with those

who prefer life in the slow lane.

Back on Kangaroo Island,

it's now the breeding season

for the animals that gave
the island its name.

This type of the western grey
kangaroo

is smaller and stockier

than its mainland relatives.

They, too, hang around in groups

known as mobs.

Each consists of up to ten females

and their babies, called joeys.

Every mob has an adult male,

known as a boomer,

keeping an eye out for them.

Now there's a newcomer
in their ranks.

The boomer checks out

any new member of his gang.

She looks the part.

That's good enough for him.

Inside the mob,

females often act as aunties

to each other's joeys.

One joey has
taken a shine to Spy Roo.

He seems to regard her

as an auntie, too.

Then, as the ultimate sign
of acceptance,

he even tries to suckle.

Despite the apparent harmony,

there are dangerous
rivalries here, too.

Competing males are everywhere,

hoping to steal a female.

Their liaison is no longer a secret.

It's something no boomer
would tolerate.

First, a bit of shoving,

Then, the claws are out.

His mob can only watch
from the sidelines.

Now for the big guns.

The kick can deliver

a blow over of two tonnes.

Victory for now.

But the boomer must
always stay on guard.

Meanwhile, peace returns.

And the joey's adopted auntie

is the centre of attention
once more.

Just off the coast of South Africa

lies a small outcrop

known as Seal Island.

Cape gulls are common here,

but this one has a camera

in its eye and belly.

Below are the Cape fur seals

that gave the island its name.

Over 60,000 of them.

They feed on the vast fish stocks

that thrive
in the cold Antarctic currents.

At this time of year,

they gather to raise their young.

Among them is a spy.

He can sneak right up close

without raising suspicion.

Touching noses shows

they are totally at ease.

All around, the pups
are growing fast.

Fed on their mother's full-fat milk,

they quickly outgrow

their island home.

Everyone is squabbling over space.

Soon they must venture
into the water,

including our spy.

Female seals are known to adopt
orphans.

Perhaps this is why Spy Seal

is creating interest.

He's also a welcome playmate

to the younger seals.

But in nature,

danger is never far away.

Spy Gull is patrolling the waters

around the island.

Below, the ocean's greatest
predator.

A great white shark.

Each year, over 40 gather here

to hunt the young seals.

Spy Seal is the first

to see the shark approach.

But one young seal

is still blissfully unaware.

Seen from above,

a game of cat and mouse unfolds.

The seal may be young,

but he's quick and manoeuvrable.

From above,

something remarkable becomes clear.

The seal pup can turn faster
than the shark.

He deliberately gets behind it,

out of sight.

Whenever the shark turns,

the seal stays right on its tail.

Until finally...

..he makes his escape.

Our spy is now the only seal
remaining.

The shark begins to circle...

..checking out
yet another likely target.

Sharks can detect

minute electric fields.

Spy Seal has plenty of those.

At every pass, it gets closer.

The first bite is exploratory.

Testing if it's a worthwhile meal.

This wasn't what it was looking for.

Battered and bruised,

Spy Seal is left alone.

But it's a long way

back to the island.

Over 5,000 miles away,

off the coast of Western Australia,

is Rottnest Island,

home to one of the most
photogenic creatures on Earth.

Meet the quokkas,

the only native mammals
to live here.

These marsupials

have no other living relatives

and exist only in a few places
in Australia.

They have a friendly reputation.

So our spy should fit right in.

It's all going to plan.

As few predators are found
on the island,

they are curious and welcoming.

Spy Quokka's mission is to find out

how they raise their young.

Quokkas are vegetarians

and tea tree is one
of their favourites.

Behind their cute smile

are some razor-sharp teeth.

And they use their five-fingered
hands for grasping.

Quokkas eats so much vegetation,

they rarely need to drink.

But this is what our spy
has come to see.

A baby quokka.

A joey, just three months old.

All marsupials

carry their babies in a pouch.

Quokkas are no exception.

For the last three months,

he's relied on his mother's milk.

Now he's trying solid food.

But, as a result,

he's getting too big for his pouch.

Withholding food is one way

to deal with the problem.

It's already quite
a squeeze to get out,

but there's a big,
wide world to explore.

He's going to need a lot
of looking after.

Our spy now witnesses

another sight of quokka life.

For all their cuteness,

quokkas will fight over food,

especially tea tree.

Even the joey's mother

isn't keen to share.

With all this competition,

Spy Quokka is on dangerous ground.

A peace offering.

That seems to have done the trick.

For the baby, it's been quite enough

adventure for one day.

Across the Indian Ocean,

on the remote island of Komodo,

the east winds are blowing.

They bring the dry
and harsh conditions

that trigger the breeding season

for the infamous Komodo dragon.

Unique to these tiny
Indonesian islands,

they are the largest
lizard in the world.

Up to three metres in length.

The forked tongue is used

to detect odours.

This male is seeking a mate.

Spy Dragon
looks just like the real thing.

Certainly worth a closer inspection.

He rakes his claws over the skin

to try to release pheromones

to reveal its sex and age.

Then checks with his tongue.

She may look the part,

but she doesn't smell the part.

There's nothing of interest here.

He heads to the water hole -

always a good meeting place

at this time of year.

Here, Spy Pig is also on duty.

As wild pigs are often
eaten by dragons,

it soon attracts interest.

Again, he uses his tongue
to check its scent.

But there is something

far more interesting on the wind.

A real female dragon.

Some wooing is required.

His advances captured by a mud cam.

She stops to show she's interested.

This time, raking the skin

gives off all the right signals.

Our spy captures what must be

the closest reptiles get

to a tender moment.

But pheromones travel far.

Another male is also on the scent.

With testosterone raging,

a fight is inevitable.

The female has a vested interest
in the outcome,

so follows behind.

They test their strength
by wrestling.

The victor pins his rival
to the ground.

And finally sees him off.

But with everyone
in a fighting mood,

Spy Pig is no longer quite so safe.

The other dragons are showing
interest, too.

He may be down,

but he keeps on filming.

At nearly 100kg,

these dragons are ten times heavier

than their victim,

and they've hardly even started.

For the first time ever,

a view inside a dragon's mouth.

One laden with venom

and toxic saliva,

dosed with over 50 types

of deadly bacteria.

But as Spy Pig doesn't taste edible,

he's soon abandoned.

Anyway, the Dragons still have

romance on their mind.

Spy Pig's days are well
and truly over.

While our friendly dragon
survives unscathed.

In the middle of the South Atlantic,

the Falkland Islands

become the focus of another
spectacular event.

Rockhopper penguins

have arrived to breed.

Here, too, is Spy Penguin.

Part of an army of penguin cams

ready to provide total coverage.

While the mothers
are fishing out at sea,

the males are left

on parenting duties.

One is already in trouble.

His chicks have hatched,

and his partner is yet
to return with food.

Just off shore, another spy

also awaits the penguins' return.

They arrive without warning.

Just getting ashore
is difficult enough.

Another penguin cam is there

to film their achievement.

Many more will be needed

to cover the huge challenge ahead.

To reach their chicks,

somehow the penguins must scale

this 100-metre cliff.

Just reaching the first level

is tricky enough.

But rockhoppers will never let

one mishap get in their way.

Even though at every step

they risk going back to the start.

With a little fancy footwork,

this female is faring best of all.

However, she still needs

to reach the next level up.

But they're not called
rockhoppers for nothing.

Although a little practice
is required.

Or, perhaps, an easier route.

But nothing here is ever that easy.

Next, this aquatic bird

must become a climber,

with beaks and bills

acting as crampons.

Fortunately, a thick layer
of fat cushions her fall.

She follows an ancient route.

The sides carved out
by the beaks and claw marks

of generations before her.

For some, the intensity of the climb
brings out a competitive streak.

But our heroine avoids
getting involved.

Instead, she finds some
welcome relief.

A natural shower.

A quick freshen up before
meeting her partner.

Just one more level to complete
what's known in the trade

as a chimney climb.

Now it's just a matter
of finding her mate.

Not so easy when everyone
here is equally feisty.

The reunion will be short.

to go fishing.

They will each take shifts
over the next six weeks,

until the chicks are ready
for a life at sea.

Back in the Galapagos Islands,
the moss-shrouded mountains

of Santa Cruz set the scene
for another remarkable gathering.

Boulder-cam is on a mission to
find this rare and secret event.

It's not long before it finds
the first hopeful sign.

A giant Galapagos tortoise.

Unique to these islands, at nearly
two metres head to tail,

they are the biggest in the world.

In these moist mountain valleys,
there is plenty for them to eat.

But it's so tough and fibrous,
they must feed for eight hours a day

just to get enough nutrients.

It's not the only tortoise here.

There's a spy in disguise.

It's the breeding season.

Spy Tortoise could be just
what he's looking for.

Although he's never come across
a female like this before.

With 400 kilos on her back,

it's a good job her shell
is reinforced.

Well, that was never going to work.

But he soon picks up the scent
of a real female...

..with both spies hot on his heels.

He would have smelt her
from over a mile away.

A useful skill in such
a dense forest.

It's now just a case
of following the sound.

TORTOISE GROANS

Mating can last for hours.

TORTOISE GROANS

It never ends gracefully.

Finding a mating pair is quite
an achievement.

But our spies have yet
to complete their mission.

But this is a hopeful sign.

In fact, Galapagos tortoises
are everywhere.

And here it is...

..their Shangri-La.

An incredible gathering
of over 30 giant tortoises.

All enjoying the fresh water

found in just a few mountain pools.

It's a haven for
other wildlife, too.

The Galapagos pintail duck.

For the tortoises,
the pools not only offer a place

to drink and chill, but to
absorb the food they've eaten.

Our spy's mission
is finally complete.

Leaving the tortoises to
digest their high-fibre meal.

Next time, our spy creatures
venture to the Poles to find

the extraordinary animals
that thrive in a world

of ice and snow.
