In the heart of South East Asia

lies the tropical island

on Earth.

This is a lost world,

home to the beautiful

carnivores...

It may seem like paradise...

...but from it's sun-drenched
shores...

through ancient jungles...

...it's a struggle
just to survive...

but this struggle has led to
extraordinary adaptations...

and given rise to possibly
the greatest diversity of life

found on any island.

Isolated in vast tropical

These islands of wonder

Narrator:
Off the coast of Asia,

330 miles east of Singapore

and a thousand miles
north of Australia

lies the island of Borneo.

♪♪

♪♪

Its shores are fringed
by a tangle of mangroves

and flooded forests...

criss-crossed
by a network of rivers.

[ Birds calling ]

This waterlogged world
is the last stronghold

for a primate found
no where else on Earth...

♪♪

The proboscis monkey...

♪♪

This male's enlarged nose
serves one key purpose...

to attract a mate.

♪♪

And his super-sized snout

has secured him a harem
of adoring females...

♪♪

♪♪

...and their offspring.

It will take this baby
7 long years

to grow a nose
to rival his father's.

But for these monkeys,

their pot-bellies
are the key to their survival.

There is precious
little nutrition to be found

in the bitter leaves
of these flooded forests.

Proboscis have evolved
an enlarged gut

to extract any goodness
there is.

Still, only the youngest leaves
have enough nutrition

to be worth eating.

So the male must lead his troop
up to a mile a day

in search of fresh growth.

♪♪

♪♪

♪♪

But their route
is often blocked...

by one of the many rivers
that cut through the forest...

...patrolled by giant
predators...

♪♪

...like the saltwater crocodile,

which grows to more
than 16 feet long

and can weigh up to a ton.

To reach the young,
juicy leaves on the other side,

the group will have to cross.

But the male is hesitant.

♪♪

♪♪

Instead, it's the alpha female
who takes the lead.

[ Screeching ]

[ Splashing ]

Sounds of their splashes
carry 700 feet

through the water

and can draw unwanted attention.

But unlike most other monkeys,

proboscis are excellent
swimmers.

To survive here,
they have evolved webbed feet.

♪♪

Finally, the reluctant male
makes his move.

But a mother and baby
have been left behind.

This time the whole family
has made it...

At last they can feed
on the succulent fresh leaves.

The challenge of living in this
beautiful

but difficult environment

forces these monkeys to risk
their lives in search of food,

changing their behavior
and their bodies.

It is this way
all across Borneo,

where over 6,000 unique species
have adapted

to face these challenges
over thousands of years...

evolving from ancestors that
were isolated here long ago.

Borneo was once joined
to Thailand

and mainland Malaysia...

Part of a vast landmass,

home to one of
the oldest forests on Earth.

But when the last ice age ended
10,000 years ago,

sea levels rose,

leaving Borneo and
its ancient forests stranded.

♪♪

The surrounding shallows
are now home

to some of the richest
coral reefs in the world.

♪♪

♪♪

A single reef can support
more species of coral

than the entire Caribbean Sea.

♪♪

♪♪

For the people that live
on Borneo's coast,

accessing these submerged riches

has led to
an extraordinary adaptation.

The Bajau Laut --
People of the Sea.

♪♪

Over generations of diving,
their bodies have transformed.

♪♪

♪♪

Their spleens are 50%
larger than average.

It's believed this provides
their blood

with more oxygen for diving.

They can hold their breath
for over 3 minutes

and spend 60% of
their day hunting underwater,

longer than almost any other
human being.

The Bajau Laut
settled on Borneo's coasts

still rely on the sea
for nearly all their needs.

the Bajau continue to live off

one of richest coral reefs
in our seas.

But as you head inland,

conditions get tougher,
pushing life to extremes.

[ Birds calling ]

Just 10 miles from the coast
lies a steamy jungle world,

one of the last
surviving fragments

of an ancient
lowland rainforest.

Covering an area larger
than California,

less than a square mile can hold
thousands of species of trees.

♪♪

But one group of giants
dominate...

the Dipterocarps.

Towering up to 330 feet high,

they are the tallest rainforest
trees in the world.

Their branches form
a unique canopy world...

...that is home to the world's
largest tree-dwelling animal...

In orangutans, the bond between
mother and baby is very strong,

and this youngster will stay
with his mother

for up to 8 years.

[ Baby orangutan squeaking ]

He has a lot to learn.

Many of the forest
leaves here are poisonous...

but his mother can identify
around 500 species

that are safe to eat.

Remarkably, though,

we now know their knowledge
goes much further.

the orangs here

for over 20 years...

anywhere in the world.

Imagine what else is left to be
discovered in this rich canopy?

[ Birds calling ]

90% of Borneo's jungle life
is found up here.

A single tree can hold 1,000
different species.

This leads to intense
competition for food and space.

canopies...

life has evolved
in wondrous ways.

It feeds directly
from the giant trees,

...on the forest floor,
it's an impoverished world.

In these lowland forests,
30 miles or so from the coast,

the giant tree roots suck up
most of the nutrients...

leaving the soil depleted.

Since Borneo was cut off
10,000 years ago,

it's thought that many
of the large mammals died off.

With little to eat down here,

many that did persist
have shrunk.

Confined to her protected
forest sanctuary...

...the exceedingly rare
Bornean sun bear.

Weighing just 130 pounds,

it's the smallest bear
in the world.

This fallen branch
is a prized treat.

Filled with wood grubs
and beetles.

Nothing is wasted...
even a noxious millipede.

But it's not enough to sustain
even this little bear.

The real prize sits high above.

Guided by her exceptional
sense of smell...

...the sweet scent of honey.

defy gravity.

A common fairy bluebird.

It's a meager kill,

not enough to feed themselves,

But the Penan have an ingenious
way of reaching out to others.

Along the path,

they plant sticks on
which they leave messages.

A single feather signifies
they have caught a small bird.

And a folded, empty leaf shows
that they are hungry

and in need of food.

It's an ancient sign language
known as "Oroo."

Narrator: With more than 50
different symbols,

Narrator:
With their unique sign language

and communal bonds,

the Penan have overcome
the challenge

of finding enough food
on Borneo's forest floor.

With every step inland,
Borneo changes.

Fifty miles from the coast,
the elevation begins to rise,

and the lowland jungle

gives way to enormous caves...

and Deer cave is one of the
largest subterranean chambers

in the world.

Almost 700 feet wide
