THE MORE YOU KNOW ON NBC.

DYLAN: HI, I'M DYLAN
DREYER, AND WE'RE ABOUT TO

EMBARK ON ANOTHER "EARTH
ODYSSEY."

ON TODAY'S EPISODE, WE
EXPLORE THE HIDDEN BEAUTY

OF THE CARIBBEAN ISLANDS.

SURROUNDED BY CRYSTAL BLUE
WATERS AND WHITE SANDY

BEACHES, IT'S HARD TO
BELIEVE WHAT'S BUBBLING

BENEATH THE SURFACE.

THE CARIBBEAN HAS AN
EXPLOSIVE SECRET.

VOLCANOES AND EARTHQUAKES
ROCKING THE LAND,

ULTIMATELY CREATING A
PARADISE ON EARTH.

FIND OUT HOW THESE
ISLAND-HOPPING LIZARDS

HITCH A RIDE THROUGH THE
CARIBBEAN, AND LATER, DIVE

DEEP INTO A COLORFUL MAZE
OF CORAL REEFS.

[MUSIC]

DYLAN: BEHIND ME IS A
COLONY OF AFRICAN

BLACK-FOOTED PENGUINS, A
SPECIES THAT'S ADAPTED TO

THE BALMIER TEMPERATURES
OF THE SOUTHWESTERN COAST

OF AFRICA.

IT SHOWS FIRSTHAND HOW
IMPORTANT ADAPTATION IS TO

SURVIVAL IN NATURE.

DOWN IN THE CARIBBEAN,
IGUANAS HAVE ADAPTED BY

LEARNING HOW TO TRAVEL
FROM ISLAND TO ISLAND.

WITH THEIR DETERMINATION
TO SURVIVE, THIS SPECIES

IS A CARIBBEAN SUCCESS
STORY.

LET'S SEE HOW THEY DID IT.

A CHAIN OF SEVEN THOUSAND
CARIBBEAN ISLANDS LIE

BETWEEN THE NORTH AND
SOUTH AMERICAN CONTINENTS.

VOLCANIC ISLANDS AND REEFS
DOT THE CRYSTAL BLUE

WATERS OF THE CARIBBEAN
SEA.

THEY RANGE IN SIZE AND
SCOPE, EACH WITH ITS OWN

ANIMALS AND PLANTS.

BUT WHY LIMIT YOURSELF TO
JUST ONE ISLAND?

THIS LAND ANIMAL FOUND A
CLEVER WAY TO ISLAND-HOP.

TREES AND BUSHES GET
UPROOTED DURING MAJOR

HURRICANES WHEN THEY BLOW
THROUGH THE ISLANDS.

THE LESSER ANTILLEAN
IGUANAS ARE PARTICULARLY

GOOD AT HITCHING A RIDE ON
THE PASSING DEBRIS.

THESE LIZARDS HAVE NOW
COLONIZED MUCH OF THE

EASTERN CARIBBEAN ISLANDS.

ON THE ISLAND OF DOMINICA,
TEN THOUSAND IGUANAS

OCCUPY FORESTS CLOSE TO
THE SHORELINES.

THE REPTILES LIVE BY A
COLORFUL ORDER.

THE BRIGHT GREEN IGUANAS
ARE EITHER YOUNG OR

FEMALE.

AS THEY GET OLDER, THEY
LOSE THEIR GREEN SHEEN,

BUT GAIN GREATER RESPECT
FROM THEIR FELLOW LIZARDS.

THE SENIORS ARE DARK GRAY
WITH PALE BLUE SCALES ON

THE SIDES OF THEIR HEADS.

THEY CAN OVERSEE AS MANY
AS SEVEN POTENTIAL

FAMILIES AT A TIME.

APRIL IS NESTING SEASON.

THE OLDER MALES WILL
DEFEND THEIR MULTIPLE

HOMES FROM INVADERS.

AN AGGRESSIVE SHOW OF
HEAD-BOBBING TELLS ANY

CHALLENGERS THAT THEY'RE
NOT WELCOME.

JUST KEEP MOVING.

THE FEMALES DIG A
GOOD-SIZE NEST THAT CAN

HOLD AS MANY AS 18 EGGS.

ONCE THEY ARE NESTLED IN
THERE, HER WORK IS DONE.

SHE ALLOWS THE CARIBBEAN
SUN TO KEEP THESE EGGS

WARM.

THE EGGS ARE HIDDEN THREE
FEET UNDER THE SAND, YET

HUNGRY PASSERSBY STILL TRY
TO DIG THEM UP.

THESE ARE THE GROUND
LIZARDS WHO ARE NATIVE TO

THE ISLAND OF DOMINICA.

THEY ARE KNOWN BY THE
LOCALS AS ABOLO.

SCAVENGERS BY NATURE, THE
GROUND LIZARDS TRY TO

STEAL EGGS FROM AN
UNSUSPECTING IGUANA.

LUCKILY, THESE EGGS ARE
READY TO HATCH.

BRIGHT GREEN LIZARDS SWARM
OUT OF THE NESTS, READY TO

FACE THE WILDER SIDE OF
DOMINICA.

THIS ISLAND IS THE WETTEST
CARIBBEAN ISLAND.

IT RECEIVES AN AMAZING
THREE HUNDRED INCHES OF

RAIN EVERY YEAR.

THAT'S 25 FEET OF WATER.

FRESH RAINWATER FLOWS DOWN
THE ISLAND'S COUNTLESS

WATERFALLS FROM HIGH IN
THE MOUNTAINS TO THE

CARIBBEAN SEA BELOW.

THAT RAINWATER CARRIES
CRITICAL NUTRIENTS FOR THE

ANIMALS AND PLANTS.

LOOK CLOSELY, AND YOU'LL
SEE THE WATER BUBBLING

BELOW.

THAT'S WHERE AN ACTIVE
VOLCANO SIMMERS THROUGH

CRACKS UNDERWATER IN THE
OCEAN FLOOR.

ALL OF THESE FACTORS PLAY
A KEY PART IN THE

FORMATION OF THE
CARIBBEAN'S INCREDIBLE

CORAL REEFS.

THE REEFS ARE LIVING AND
BREATHING ORGANISMS CALLED

POLYPS, A NETWORK OF
BILLIONS OF TINY ANIMALS.

MANY OF THE REEFS' FISHES
AND ORGANISMS ARE ONLY

FOUND HERE IN THE
TURQUOISE BLUE WATERS OF

THE CARIBBEAN.

THE REEFS' RICH ECOSYSTEMS
SHELTER MORE THAN EIGHT

HUNDRED DIFFERENT
VARIETIES OF BRIGHTLY

PAINTED FISH, NOT TO
MENTION OTHER CREATURES

LURKING AROUND, A MAZE OF
UNIQUE AND ABUNDANT

WILDLIFE THAT THRIVES ON
THESE VOLCANIC ISLANDS.

COMING UP ON "EARTH
ODYSSEY," BOILING LAKES

BREAK THROUGH THE TROPICAL
PARADISE, AND THEN, FIND

OUT HOW THE FIRST PEOPLE
SETTLED ON THE CARIBBEAN

ISLANDS.

.

ANNOUNCER: WE NOW RETURN TO
THE MORE YOU KNOW ON NBC.

ANNOUNCER: THIS EPISODE OF
"EARTH ODYSSEY WITH DYLAN

DREYER" IS BROUGHT TO YOU
BY RIPLEY'S AQUARIUMS.

DYLAN: NORTH OF TRINIDAD,
THERE IS A SMALL CHAIN OF

ISLANDS KNOWN AS THE
WINDWARD AND LEEWARD

ISLANDS.

GREAT SLABS OF ROCK CALLED
TECTONIC PLATES BORDER

THESE ISLANDS, AT ONE TIME
ROCKING THIS AREA WITH

VOLCANOES AND EARTHQUAKES.

THERE ARE 17 ACTIVE
VOLCANOES IN THE

CARIBBEAN, EVEN ONE THAT'S
STILL UNDERWATER.

DOMINICA ISLAND IS THE
YOUNGEST ISLAND OF THE

CARIBBEAN, ONLY 26 MILLION
YEARS OLD WITH MOUNTAIN

PEAKS ALMOST A MILE HIGH.

THE ISLAND HAS NOT
EXPERIENCED A VOLCANIC

ERUPTION IN HUNDREDS OF
YEARS, YET THERE IS A

GREAT DEAL OF ACTIVITY
JUST BELOW THE SURFACE

SOMETIMES BREAKING
THROUGH.

A BOILING LAKE MORE THAN
TWO HUNDRED DEGREES.

DON'T STAND TOO CLOSE.

THEY HAVE OPENINGS IN THE
EARTH'S CRUST CALLED

FUMAROLES.

MORE THAN TWO HUNDRED FEET
WIDE, IT LIES WITHIN THE

CRATER OF DOMINICA'S
INACTIVE VOLCANO.

THESE MASSIVE VENTS
RELEASE A POISONOUS

COCKTAIL OF GASES FROM
DEEP WITHIN THE VOLCANOES

BELOW, BUT THERE IS AN
UPSIDE TO VOLCANOES.

NUTRIENT-RICH SOIL HAS
CREATED IDEAL GROWING

CONDITIONS FOR CRITICAL
WILDLIFE.

BEFORE CHRISTOPHER
COLUMBUS SET SAIL TO THE

NEW WORLD AND LANDED IN
THIS REGION, THERE WERE

PEOPLE ALREADY LIVING ON
THE CARIBBEAN ISLANDS.

AROUND FOUR THOUSAND YEARS
AGO, IT'S THOUGHT THAT

THEY ORIGINALLY MADE THEIR
WAY TO THE ISLANDS BY BOAT

FROM NEARBY SOUTH AMERICA.

THESE SETTLERS WOULD
TRAVEL BETWEEN ISLANDS IN

HAND-CARVED CANOES.

THEY CHOSE TO LIVE IN THE
MORE MOUNTAINOUS VOLCANIC

ISLANDS.

BACK IN SOUTH AMERICA, THE
PEOPLE COULD HUNT ANY

NUMBER OF ANIMALS FOR
FOOD.

WHEN THEY FIRST ARRIVED,
THEY MUST HAVE BEEN AMAZED

THAT THEY WERE THE LARGEST
ANIMALS ON LAND.

CUT OFF FROM THE REST OF
THE WORLD AND BORN OUT OF

THE VOLCANIC ERUPTIONS,
THE ISLANDS PROVED TO BE

TOO MUCH OF AN OBSTACLE
FOR THE LARGER MAMMALS.

HUNGRY FOR PROTEIN, THE
FIRST PEOPLE TURNED TO

WILDLIFE IN THE SEA TO
SURVIVE.

THE SETTLERS QUICKLY
BECAME EXPERT FISHERMEN.

THEY ALSO LEARNED LAND AND
WHAT PLANTS WOULD BE SAFE

TO EAT.

JUST LIKE THE WILDLIFE ON
THESE ISLANDS DRIFTING IN

THE SEA, THE FIRST PEOPLE
HAD TO ADAPT TO AN

ENTIRELY NEW ENVIRONMENT.

AS THESE FIRST SETTLERS
DISCOVERED, THE CARIBBEAN

ISLANDS SUPPORT A RICH AND
DIVERSE VARIETY OF

WILDLIFE THANKS TO ITS
VOLCANIC HISTORY.

COMING UP ON "EARTH
ODYSSEY," FIND OUT HOW THE

CARIBBEAN ISLANDS PROTECT
THEMSELVES WHEN POWERFUL

STORMS COME CALLING.

THAT'S NEXT.

.

ANNOUNCER: WE NOW RETURN TO
THE MORE YOU KNOW ON NBC.

DYLAN: WELCOME BACK TO
"EARTH ODYSSEY."

I'M DYLAN DREYER.

HERE AT RIPLEY'S AQUARIUM
OF THE SMOKIES, THERE'S A

STRANGE-LOOKING SOUTH
AMERICAN FISH WHO SETS HIS

SIGHTS TWICE.

THIS IS THE ANABLEPS, AND
IT'S THE ONLY ANIMAL IN

THE WORLD EQUIPPED WITH
BIFOCALS.

YOU'RE ABOUT TO SEE WHY
HAVING TWO PUPILS IN EACH

EYE CAN BE A LIFE-SAVER,
LITERALLY.

THE CARIBBEAN ISLANDS ARE
VULNERABLE TO DEVASTATING

STORMS WITH HIGH WINDS.

KNOWN AS HURRICANE ALLEY,
THE ISLANDS NEED TO EMPLOY

EVERY DEFENSE THEY CAN
WHEN STORMS ROLL THROUGH.

A NATURAL BARRIER FOR THE
ISLANDS ARE THE MANGROVE

FORESTS.

AS THEY GROW, THEY
STRADDLE BOTH THE WATER

AND LAND, A NATURAL
BREAKWATER.

THE COMPLICATED NETWORK OF
THE MANGROVE'S ROOT SYSTEM

CREATES A BARRIER TO
POUNDING WAVES AND SURF

DURING STORMS.

TRINIDAD'S CARONI SWAMP IS
THE LARGEST MANGROVE

FOREST ON THE ISLAND.

AS THE TIDES RISE AND
FALL, THE MANGROVE FORESTS

TAKE ON A GREAT DEAL OF
SALTY WATER.

THERE ARE ONLY A FEW
PLANTS THAT SURVIVE UNDER

SUCH HOSTILE CONDITIONS,
BUT THESE MANGROVES MANAGE

TO CREATE A THRIVING
ECOSYSTEM.

NESTLED IN ITS ROOTS, THE
MANGROVES ACT AS A SAFE

HAVEN FOR SCHOOLS OF YOUNG
FISH.

THE CHANGING TIDES CREATE
A NEW SET OF CHALLENGES

AND OPPORTUNITIES FOR THE
ANIMALS WHO SHELTER IN THE

MANGROVES.

A FISH OUT OF WATER, THE
FOUR-EYED FISH IS

PERFECTLY HAPPY TO ENJOY A
MEAL OF INSECTS WHEN THE

TIDE IS OUT.

WHEN THE WATER ROLLS BACK
IN, THE FISH SWITCH TO

CRUNCHY LITTLE CRUSTACEANS
SKIMMING THE WATER'S

SURFACE.

WITH A DIET OF SURFACE
ANIMALS, THE FOUR-EYED

FISH HAVE TO WORK DOUBLE
DUTY TO WATCH FOR POSSIBLE

THREATS, ONE OF WHICH IS
THE SPECTACLED CAIMAN.

THIS REPTILE SHARES HIS
FAMILY LINE WITH

ALLIGATORS.

THE CAIMAN CAN LIVE IN ALL
TYPES OF RIVERS AND

LOW-LYING WETLANDS, BUT HE
PARTICULARLY ENJOYS THE

STILL WATERS OF THE SWAMP.

FOUR EYES ARE CERTAINLY
BETTER THAN TWO WHEN YOU

NEED TO WATCH FOR
PREDATORS; HOWEVER, IT'S

JUST A CLEVER ADAPTATION.

THIS FISH ONLY HAS TWO
EYES.

EACH EYE HAS TWO PUPILS.

THE TOP HALF FOCUSES ABOVE
THE WATER.

THE BOTTOM HALF KEEPS A
LOOKOUT BELOW.

WHEN THE TIDE IS LOW,
ANOTHER INHABITANT OF

CARONI'S GLOPPY, THICK MUD
MAKES AN APPEARANCE,

CRABS.

A TEASPOON OF THIS MUD
SUPPORTS ABOUT TEN MILLION

BACTERIA, PLENTY TO HELP
GROW A DIVERSITY OF TINY

CREATURES.

FIDDLER CRABS EXTRACT
CHOICE BITS FROM THE MUD

WITH THEIR ONE LITTLE
CLAW, BUT SUCH PRECISE

WORK TAKES TIME AND
PATIENCE.

COMING UP, SNAP TO IT.

FIND OUT WHY THESE
COLORFUL LITTLE BIRDS ARE

MAKING SUCH A RUCKUS.

.

ANNOUNCER: WE NOW RETURN
TO THE MORE YOU KNOW ON NBC.

DYLAN: TRINIDAD IS THE
SOUTHERNMOST ISLAND IN THE

CARIBBEAN.

THIS IS WHERE THE SOFT
TURQUOISE WATER MEETS ITS

ROUGHER COUSIN, THE
ATLANTIC OCEAN.

INSIDE TRINIDAD'S FORESTS,
THE GOLDEN-HEADED MANAKIN

BIRDS ARE PLANNING THEIR
OWN MEETING.

THESE TINY BIRDS ARE
LOOKING FOR A POTENTIAL

DATE.

THE ONLY WAY TO SETTLE
THIS IS TO HAVE A

DANCE-OFF ON THEIR OWN
PERCH.

EACH ONE SHOWING OFF ITS
MOVES, TRYING TO GRAB THE

ATTENTION FROM A PASSING
FEMALE.

[BIRDS CHIRPING]

FURTHER IN THE FOREST,
ANOTHER GROUP OF MANAKINS

TRY THEIR LUCK.

THESE MALE WHITE-BEARDED
MANAKINS STAY CLOSE TO THE

GROUND.

EACH BIRD KEEPS ITS AREA
TIDY, REMOVING ANY LEAVES

OR STRAY BRANCHES.

THESE MANAKINS PUT ON
THEIR OWN SHOW.

THEY RAISE THEIR CHIN
FEATHERS TO IMPRESS THE

LADIES.

THE FLUFF OF WHITE AT
THEIR THROATS LOOKS LIKE A

BEARD, BUT THAT'S NOT ALL.

WHEN THE BIRDS STRIKE
THEIR WINGS TOGETHER, THEY

MAKE A DISTINCT SNAPPING
NOISE.

FINALLY, THEY GET A
PASSING FEMALE'S

ATTENTION.

SHE'S NOT NEARLY AS FLASHY
AS THE MALES, BUT YOU'D

NEVER KNOW IT BY THE WAY
THEY'RE ACTING.

[BIRDS CHIRPING]

PERHAPS IT'S THEIR
OVER-EAGER ATTITUDES.

WHATEVER THE REASON, THEY
BOTH FALL SHORT THIS TIME.

THE FEMALE FLIES OFF TO
FIND ANOTHER PERCH TO

SETTLE DOWN.

TRINIDAD ONLY SEPARATED
FROM SOUTH AMERICA 12,000

YEARS AGO.

THAT'S WHY THIS CURIOUS
LITTLE FELLOW ONLY SETTLED

HERE ON TRINIDAD RATHER
THAN THE OTHER CARIBBEAN

ISLANDS.

THE SILKY ANTEATER IS THE
SMALLEST ANTEATER IN THE

WORLD.

HE MIGHT BE LITTLE, BUT
HE'S TOUGH.

THE SILKY ANTEATER CAN
VACUUM UP AS MANY AS FIVE

THOUSAND ANTS.

THAT'S JUST A MIDNIGHT
FEAST FOR THIS

NIGHT-LOVING ANIMAL.

DURING THE HOT DAY, HE
PREFERS TO SLEEP OFF HIS

MEAL OF CREEPY INSECTS ON
A STURDY TREE BRANCH.

IT'S ISLAND LIFE FOR THESE
CARIBBEAN NATIVES.

WITH PLENTY TO EAT AND
DRINK, PLUS THE BEAUTIFUL

CLEAR BLUE WATERS, NATURE
SETS THE STAGE FOR A

COLORFUL DISPLAY.

THANKS FOR JOINING ME ON
THIS EXCITING EXPEDITION

THROUGH THE WILD SIDE OF
THE CARIBBEAN ISLANDS.

WE'VE SEEN HOW THIS
TROPICAL PARADISE TEEMS

WITH A DIVERSE AND
ABUNDANT ARRAY OF

WILDLIFE, ALL OF WHOM FIND
WAYS TO SURVIVE AND THRIVE

IN ONE OF THE EARTH'S
GREAT VOLCANIC HOTSPOTS.

WE'LL SEE YOU NEXT TIME ON
"EARTH ODYSSEY."
