All language subtitles for Brazil A Natural History 4of5 Paradise Coast 1080p

The coastline of Brazil is one of
the most spectacular in the world.

Yet most of us have only heard
only of Copacabana beach.

But Brazil's Atlantic coast
is much more than a strip

of sun drenched sand.

There are strange sculpted dunes,

remote rocky isles,

and unique tropical reefs.

The shallow seas hold a wealth of wildlife.

Humpback whales prowling
octopus and moray eels,

deadly snakes, and spinner dolphins.

All live along Brazil's extraordinary coast.

Brazil's coast stretches nearly 7500 kilometers.

From tempered southern seas to the tropics.

It's lined with wild rocky shores,

and tropical paradise beaches.

The waters here attract many visitors.

Far out to sea, humpback whales are heading north

towards Brazil's coast.

The whales are on an urgent mission.

They left their Antarctic feeding
grounds three weeks ago,

and they've been swimming nonstop ever since.

The whales have reached
Brazil's southern most waters,

but it will be another week before they arrive

at their final destination.

These southern Brazilian shores
are pounded by wild weather.

The waves churn out the sand.

And a chill wind, called the
Minuano sculpts the landscape.

Every year the wind and waves combine to create

a large futile lagoon just in land of the beach.

Huge flocks of birds

take advantage of the abundant
food in these waters.

Many have flown thousands of kilometers

from North America to feed here.

Sandpipers need the lagoons to
build up their fat reserves

before their long journey home,

as do the rare Hudsonian Godwits.

They use their longer bills to
probe deeper into the sand.

The migrants mingle with the residents.

The flamingos are filter
feeders, stirring up the mud

with their feed before sifting

the murky water for nutrients.

The lagoon is so rich in food that

the flamingos never have to leave.

This is the only place in
Brazil where they can be see

all year round.

But by April,

the summer visitors are ready to leave

for their breeding grounds.

Some as far away as the high arctic.

The Godwits will fly nonstop at an astonishing

9000 kilometers, fueled by the food of the lagoon.

On their journey, they pass the well named

magnificent frigatebird.

A true master of the coastal waters,

it soars effortlessly on it's two meter long wings

as it searches for food.

It feeds on fish without wetting it's feet.

In fact, strangely for a seabird,

it doesn't have waterproof feathers.

A landing in the sea could be fatal.

They are amazing agile flyers,

but for all their elegance,
they're not above piracy,

trying to steal an easy meal from each other.

Magnificent frigatebirds
are found along the entire

7500 kilometers of the Brazilian coastline.

And they nest on many of the islands.

But not this idyllic looking island.

A mere 32 kilometers from the
mainland, Queimada Grande

lies just below the tropic of Capricorn.

Yet, no one lives on this island.

In fact, the Brazilian navy forbids visitors.

And with good reason.

The island is the home of this
snake, the golden lance head.

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

And the island is literally covered in snakes.

No one has been brave, or
foolish enough to count them,

but estimates suggest their as many as 4000 snakes

on this small island.

Another assessment calculated there is one snake

for every square meter.

The golden lance head's
closest relative is a snake

that preys on mammals, but
there are no mammals here,

so the snakes have taken to
the trees to hunt birds;

no easy task.

This part of the coast
suffers frequent rainstorms.

And when showers sweep in from the sea,

the birds dive under the canopy of the forest

looking for shelter.

The snakes are waiting.

They wriggle the tails, trying to fool the birds

that there's a juicy grub to eat.

The golden lance head senses
prey by heat detectors

in pits on its head.

In the cool of the rain, the
warm birds are easier to find.

The golden lance head's venom
is five times more potent

than that of it's mainland relative.

The snake needs to quickly kill a bird

for if a bitten bird manages to fly off,

it will never be found.

But the birds that live on
the island all year round,

know to avoid the snakes.

It turns out the snakes hardly ever catch

these savvy residents.

They rely almost completely on naive birds,

occasional visitors to the island.

The snakes go months without food.

Queimada Grande offers no
welcome to the frigatebirds.

A safer island is one rightly
famed for it's seabirds.

110 kilometers north, or 10 hours on the wing

from snake island, lies Atol das Rocas.

The frigatebirds share this island

with nesting brown boobies.

Brown booby parents take turns
to look after the babies,

and to hunt for fish.

The isolated islands are safe from predators,

but they suffer the same unpredictable weather as

Queimada Grande.

Boobies nest throughout the
year, so there are chicks

of all ages and all suffering in the rain.

The cold rain transforms the island into

a bleak, drenched rock.

For the naked youngster, unable to regulate

it's temperature, the rainstorm
poses a real threat.

The parent needs to shelter the chick

from the torrential downpour.

The birds that bred earlier
have a much older chick,

more able to weather the storm.

And a good meal will boost it's reserves.

Although the parent takes some persuading.

The younger chick is succumbing to the wet.

The mother seems to ignore the baby,

but the chick may now be so cold and weak

that it no longer prompts a instinctive response

from the parent.

The unpredictable weather makes choosing

a time to breed a gamble.

There will always be winners and losers.

But boobies are long lived birds.

Maybe next time her chick
will escape the downpours.

The brown boobies and
frigatebirds of Atol das Rocas

range of huge expanses of the coast.

They fly effortlessly over the
migrating humpback whales.

They are still steadily swimming
at five kilometers an hour.

But in a few days, their
marathon journey will be over.

The Brazilian coast is very varied,

and in sheltered stretches
mangroves and mud dominate.

The prop roots of the red
mango tree trap and hold mud,

which becomes a resource for
a host of small creatures.

The most obvious of which is the fiddler crab.

It's the males that want to be noticed.

Their oversized claw is used as a signal

to ward off other males,

and to attract more sensibly attired females.

The crabs biological clocks tell them to return

to the safety of their burrows
before the tide returns.

After a journey of more than 4000 kilometers,

the whales have finally arrived.

The Abrolhos Bank, over 70 kilometers offshore.

The whales have not come here to feed.

In fact, they haven't eaten since
they left Antarctic waters

and will not feed again until they return

in three months time.

They're living off fat reserves.

They've come here to mate.

And the males waste no time, chasing females

and displaying to each other.

Humpbacks are the most
acrobatic of the big whales,

and they are big, over 12 meters long

and weighing 30 tons.

Sand travels well in water, so beneath the surface

these displays must be hard to ignore.

The warm shallow waters here
are perfect for corals,

and the Abrolhos Bank is the
largest and most important

coral reef in the South Atlantic.

The reef here is unique for it has corals

found only in Brazil.

As these corals grow, they
form strange formations.

These are ancient species that have survived

only here in Brazil, isolated from the nearest

coral reefs in the Caribbean.

The Abrolhos reef provides a home

for a large number of fishes.

Shoals patrol the open water above the reef.

Other smaller fish use the many nooks and crannies

to hide from the bigger fish.

The reef operates day and night,

while many fish sleep, the
corals are still active.

It's now that they put out their tentacles

and trap the many tiny creatures of the plankton.

With fewer veracious fish
around, it's a safer time

for corals, and for crayfish.

The corals thrive here in the

24 degree Celsius shallow waters.

And it's precisely these conditions that have

drawn the humpback whales thousands of kilometers

from their feeding grounds.

Warm shallow water makes the ideal nursery

for young humpback whales.

Dwarfed by another a newborn
humpback is still a big baby,

over 4 meters long at birth
and weighing nearly two tons.

Despite it's huge size, the whale infant

is vulnerable like any other baby

and needs the support of its mother.

The baby whale has very little insulating blubber,

and so the warm water is crucial

as is the shelter as it learns to swim.

The baby will spend the first year

of its life with its mother.

In that time the young whale has a lot

to learn about humpback life.

But there's still time to play and frolic.

The baby grows rapidly.

That's not so surprising when
its mothers milk is 50% fat,

and the baby suckles frequently,

consuming over 45 kilos of milk a day.

Mother whales are very attentive,

often supporting their babies
when they surface to breathe.

It's not just the whales that
use the Abrolhos as a nursery.

The islands are important for the

magnificent frigatebirds as well.

This is one of their main breeding colonies.

The males compete for females in a curious manner,

inflating their chests and appearing like

large animated balloons.

The females survey the males from above,

picking their partners whilst on the wing.

The larger the sack, and nosier the call,

the more attractive the male seems to be.

The chicks will not fly for 22 weeks.

For the first part of that extended infancy,

both parents feed the chick.

But after about 10 weeks, the male departs,

leaving the female to do all the work.

She stays and cares for her
chick for another nine months,

even after it's able to fly.

It is the longest period of
parental care of all birds.

Frigatebirds are wonderfully adapted to

their aerial way of life.

They can stay in the air for
several days and nights,

and may even sleep on the wing.

In this manner they traverse huge expanses of sea.

Which is how they reach Arquipelago
de Fernando de Noronha.

Over 2000 kilometers away,
in the tropical Atlantic.

The islands are remote, and rugged.

The few animals that have been marooned here,

over millions of years, developed
special ways of coping.

This skink is only found on Noronha.

Its ancestors drifted across the Atlantic,

not from South America, but Africa.

They were typical little
lizards and fed on insects.

But the Noronha skink has broader diet.

In order to survive on the
island, it has found food

in an unusual place.

The lizards objective is the large flowers,

over nine meters up the tree.

There are termites to eat,
but the skink ignores them,

preferring a drink of sap before

it continues it's long journey.

The skink drinks the nectar, and as it does,

it's dabbed in pollen.

The lizards, along with the local doves

are the main pollinators of the tree.

These are the kind of strange relationships

that develop on remote islands.

Noronha is home to a pod of spinner dolphins.

They return to a shelter of a bay each morning,

after spending the night hunting
in the open Atlantic Ocean.

Here they rest and get some sleep,

but sleeping dolphins don't stop.

They have to keep swimming and breathing.

The dolphins are not totally unconscious,

only parts of their brains are
switched off at any one time.

They stay in small groups, in this way,

they're all with some dolphins half awake

with one eye open for danger.

The dolphins are relatively immune from the tides,

but the lives of creatures of the rocky shoreline

are dominated by the pull of the moon.

At low tide, huge waves batter the shoreline.

It looks like nothing could survive.

But this crab does more than survive,

it thrives amongst the breakers.

The crab has the odd name sally lightfoot.

Its streamlined body and strong legs

help it hold tight to the rocks.

It risks the surf to feed on the seaweed

that is exposed at low tide.

When the tide turns and the water rises,

the crabs retreat, preferring to stay on land

than risk predators coming in with the tide.

They wait out the high tide, safe and dry,

above the water line.

Then as the tide retreats, the
crabs make their way back

to the waters edge and their seaweed.

But the tidal journey is more
hazardous than it looks,

for these rock pools are the home of monsters.

The crabs have to cross the killing pools.

They have no choice if they are to eat.

The octopus even leaves the water and walks

over the rocks to reach the pools.

The crabs make the journey with every tide

so the killers know their routes.

A moray eel slithers over the
rocks to reach the pools.

The octopus hunts by stealth,

using it's incredible powers of camouflage.

The eel seeks out a place from which to ambush.

The crabs cross as quickly
as possible, even walking on

water in their attempt to
avoid the waiting killers.

The moray eel lies in wait at
a well used crossing point.

But the crabs are called lightfoot for a reason.

The monsters patience pays off.

The surviving crabs reach the banks of seaweed

and get to eat and live another day,

but tomorrow the tides will return,

and with them, so will the sea monsters.

When the tide is high, the
octopus leaves the rock pools

and slips into deeper water.

It is a shape shifter, able
to imitate rock and weed.

And even the color of nearby fish.

The octopus gains protection fish,

the fish follow it in hope of sharing a kill.

By late morning, the dolphins are rested

and they begin to play.

Dolphins are highly intelligent
and social animals.

One of the favored games is
pass the sargassum weed.

This game way be a way of
improving the coordination

of the young dolphins, and perfecting the skills

needed to hunt successfully.

This is a time too for adult
dolphins to chase about

and indulge in a lot of touching and caressing.

Several males will consort with a female.

The male swimming upside down to mate with her.

The female can avoid unwanted interest

by out swimming the accompanying males.

But often she chooses to stay and mate,

and with several of her consorts.

Below the playful dolphins, a ray is searching for

shrimps, crabs, and fish that hide

in amongst the rocks and seaweed.

It's often joined in its
hunting trips by a companion,

a yellow jack.

The rays electrical sense detects something.

The jack hangs on in anticipation
that the ray will stir up

something for it to pounce on.

It makes for an easier life
than hunting for yourself,

but this time, there are no scraps for the jack.

A haunting reminder of how
wild and remote Noronha is

are the shipwrecks found just offshore.

The Ipiranga was a Brazilian navy ship.

It's become a surrogate reef and home

to a wide community of fish.

Snappers and groupers patrol the decks.

In shallower water, lies an older wreck.

A Greek ship that sank in 1929.

Shoals of glassy sweepers now use it as

a secure cave to hide in.

They feed at night and will only come out

under cover of darkness.

Small mouth grunts are also nighttime feeders,

staying in tight shoals for
protection during the day.

Noronha has its own unique wrasse.

They act as cleaners, picking
parasites off larger fish

just like their cousins on reefs the world over.

But the Noronha wrasse has had to adapt

to life on these isolated islands.

They shadow big fish, hoping they will frighten

small prey for them to snatch.

They also follow the many parrot fish found here,

picking up the crumbs for the bigger fishes table.

The Noronha wrasse is a jack of all trades.

Much more flexible than its specialist relatives,

a necessity on these remote islands.

The spinner dolphins hunt in the
evening and into the night,

and so by the afternoon they
start getting more active.

It is this spectacular spinning that

gives these dolphins their name.

The reasons for the spectacular
leaps is not known.

It may be showing off, a courtship display,

removing parasites, perhaps a mix of all three.

These dolphins home is the sea around Noronha,

but the great ocean wanderers
range even further north.

Here the Brazilian coast turns west and transforms

into the most extraordinary landscape.

Lencois Maranhenses lies just two degrees south

of the equator.

It is one of the largest
expanses of dunes in the world.

Almost 1500 square kilometers
of dazzling white sand.

Away from the coast, it looks like a desert.

Yet even here, animals try to make a living.

An armadillo searches the sand, hoping to pick up

the scent of a scorpion or a spider.

It has an acute sense of smell and detect food

20 centimeters underground.

But these dunes offer nothing.

With little prospect of food, the armadillo digs

a shelter from the fierce equatorial sun.

But this strange place is not a wasteland,

for seven times as much rain
falls here as in a desert.

And the armadillo has the scent of more rain.

The storms brings about a transformation.

The landscape changes miraculously,

and creatures start to appear.

Is it the moisture trickling down through the sand

that awakens them?

We don't know.

But somehow the terrapin
knows it's time to emerge.

Oddball creatures surface from the sand,

where they have remained for
months since the last rains.

They strike out in search of water.

But it's a long way.

Eventually the toad and the
terrapin reach the pools.

But what can these new pools possibly hold?

Amazingly, there are insects and even fish

thriving in ponds that
weren't here a few days ago.

How is this possible?

Did birds transfer the eggs here?

Do the eggs lie dormant in the sand?

How most creatures get here is still a mystery.

Whatever the truth, the magical arrival of life

to these dunes is one of the wonders of the world.

All the creatures have only a few months to feed

before the tropical sun evaporates the pools

and Lencois returns to its desert like state.

By the time the pools vanish, the humpback whales

will have set off back down the Brazilian coast

heading for Antarctica.

The baby will continue to suckle for the duration

of the whole journey, but the mother will not feed

until she arrives in Antarctic waters,

five months since she last ate.

The coast of Brazil is full of strange animals,

many are visitors or wanderers,

but all depend on the clean
waters and riches of the seas.
