NARRATOR: WHEN YOU SEE THIS
SYMBOL, YOU KNOW YOU'RE

WATCHING TELEVISION THAT IS
EDUCATIONAL AND INFORMATIONAL.

THE MORE YOU KNOW ON NBC.

DYLAN: HI, EVERYONE, I'M DYLAN
DREYER.

WELCOME TO "EARTH ODYSSEY".

FROM AFRICA TO SOUTH AMERICA,
TODAY WE'RE EXPLORING THE

WORLD'S MOST TANTALIZING
TROPICAL TERRAINS.

WE'LL BEGIN IN THE CARIBBEAN,
WHERE THIS LOCAL LIZARD WORKS

SMARTER, NOT HARDER WHEN IT
COMES TO ISLAND-HOPPING.

THEN IT'S OFF TO THE GALAPAGOS
FOR A SUN-SOAKED SWIM WITH A

HERD OF ROARING SEA MAMMALS.

WE'LL VISIT THE WORLD'S LARGEST
TROPICAL WETLAND, THE PANTANAL,

HOME TO SOME OF THE MOST
SPECTACULAR SIGHTS IN NATURE.

AND LATER, A STOP-OFF AT
ZANZIBAR TO SEE WHY THIS

TROPICAL TREASURE FINDS ITSELF
IN A PINCH.

ALL OF THIS AND MUCH MORE TODAY
ON "EARTH ODYSSEY".

[MUSIC]

DYLAN: THE TROPICS ARE AN AREA
OF THE EARTH SURROUNDING THE

EQUATOR.

COVERING 36 PERCENT OF THE
PLANET'S LANDMASS, THIS REGION

RECEIVES THE MOST SUNLIGHT
YEAR-ROUND, MAKING IT AN IDEAL

HOME FOR A VAST ARRAY OF
WILDLIFE.

THE BIODIVERSITY OF THE TROPICS
IS SECOND TO NONE, LIKE IN THE

CARIBBEAN, WHERE ONE ISLAND
LOCAL HAS BECOME AN EXPERT AT

GETTING AROUND BY BOTH LAND AND
SEA.

A CHAIN OF 7,000 CARIBBEAN
ISLANDS LIES 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 300
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 800 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, WE CONTINUE OUR
TROPICAL TREK TO THE GALAPAGOS,

WHERE THE LOCAL SEA LIONS KNOW
HOW TO HAVE A ROARING GOOD TIME.

[SEA LION GROANING]

AND LATER, DISCOVER WHY THIS
UNIQUE WETLAND IS A VITAL PART

OF ITS NEIGHBOR'S SURVIVAL.

THEN, IN ZANZIBAR, WE'LL SEE A
COLOSSAL CRUSTACEAN THAT RULES

THE CRAB COMMUNITY.

ALL OF THIS AND MORE WHEN WE
RETURN TO "EARTH ODYSSEY".

.

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

[MUSIC]

DYLAN: ONE OF EARTH'S MOST
ICONIC TROPICAL ARCHIPELAGOS IS

KNOWN MORE FOR ITS UNIQUE
ECOSYSTEM THAN ANYTHING ELSE.

IT'S THOUGHT THAT THIS GALAPAGOS
SETTLER WAS ONCE JUST A

CALIFORNIA DREAMER.

SCIENTISTS SAY ANCESTORS OF THE
SEA LION LEFT THEIR NORTH

AMERICAN HOME AND SWAM NEARLY
3,000 MILES

HERE TO ISABELLA ISLAND.

GALAPAGOS SEA LIONS ARE SMALLER
THAN THEIR AMERICAN COUSINS.

TEN FEET LONG AND WEIGHING IN AT
MORE THAN 500 POUNDS, THIS ONE

IS NO PUSHOVER.

SEA LIONS ARE THE LARGEST
MAMMALS ON THESE ISLANDS AND

PROBABLY ONE OF THE FIRST
ANIMALS THAT DARWIN SAW

SUNBATHING ON THE ROCKS.

COMFORTABLE ON LAND AND IN THE
SEA, THESE CREATURES HAVE HIND

FLIPPERS THAT HELP THEM NAVIGATE
THE SLIPPERY ROCKS.

NEWBORN PUPS ARE PUT IN A
NURSERY ABOUT A WEEK AFTER

BIRTH.

ONE FEMALE IS IN CHARGE OF THE
WHOLE LOT.

THE OTHER FEMALES GO ON TRIPS,
LOOKING FOR FOOD.

THOSE TRIPS CAN LAST FOR SEVERAL
DAYS.

MEANWHILE, THE PUPS LEARN TO
SOCIALIZE AND PLAY TOGETHER.

WHEN THE MOTHERS RETURN, THEY
CALL OUT FOR THEIR YOUNG PUPS.

[SEA LION BARKING]

WHEN THE PUPS GROW OLDER,
THEY'LL LEARN TO DO THE SAME,

CALLING FOR THEIR MOTHERS.

[SEA LION BARKING]

THE MALES STAY OUT OF THE WAY
WHEN IT COMES TO PUP-REARING.

USUALLY, THERE'S ONE BULL SEA
LION CALLED A BEACHMASTER.

HE WATCHES OVER A GROUP OF
FEMALES AND THEIR PUPS, BUT HE'S

CHALLENGED BY OTHER BULLS, AND
OFTEN THE TURNOVER IS FAST.

THIS BEACHMASTER WILL PROBABLY
STAY IN CHARGE FOR A FEW DAYS

BEFORE GIVING UP.

THE LONGEST ANYONE KEEPS THE JOB
IS ABOUT THREE MONTHS.

EXHAUSTED FROM CONSTANTLY
PATROLLING, THE SEA LIONS TAKE A

COLLECTIVE NAP ON THE SHORES.

A VISITOR COMES BY TO CHECK IN
ON THEM.

THIS LAVA LIZARD FEEDS ON THE
FLIES THAT IRRITATE THE SEA

LIONS, JUMPING ON THEIR ENORMOUS
BACKS TO CATCH THE BUZZING

INSECTS.

IT'S BETTER THAN A FLYSWATTER AS
LONG AS THEY DON'T END UP POKING

YOU IN THE EYE.

COMING UP, A TROPICAL TERRAIN
THAT'S AS DIVERSE AS THE

WILDLIFE THAT CALLS IT HOME.

PLUS, THE FOOD THAT MAKES THE
COCONUT CRAB OF ZANZIBAR GO

NUTS.

ALL OF THIS AND MORE WHEN WE
RETURN TO "EARTH ODYSSEY".

.

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

[MUSIC]

DYLAN: EVERY YEAR IN THE
TROPICS IS DEFINED BY TWO STARK

OPPOSITES, THE WET SEASON AND
THE DRY SEASON.

RAIN IS A KEY DRIVING FORCE FOR
ALL LIFE.

THE ARID DESERTS OF NORTH AFRICA
SEE LESS THAN FIVE INCHES OF

RAIN PER YEAR, BUT OUR NEXT
LOCATION IS HOME TO THE LARGEST

WETLAND ON EARTH, AND IT'S MORE
THAN JUST ABUNDANT WATER THAT

MAKES THIS PLACE A WONDERLAND.

THE PANTANAL, ONCE EXTREMELY
DRY, IT HAS BEEN TRANSFORMED

INTO A WATER WORLD ONCE MORE.

ITS SWOLLEN RIVERS FUNNEL SOUTH,
JOINING THE PARAGUAY RIVER, THEN

MERGE WITH THE PARANA, THE
SECOND LONGEST RIVER IN SOUTH

AMERICA.

TOGETHER, THEY DRAIN A FIFTH OF
THE ENTIRE CONTINENT.

ONE OF THE TRIBUTARIES PASSES
THROUGH IGUAZU FALLS...

...THE MIGHTIEST WATERFALLS IN
THE AMERICAS.

SHAPED LIKE A GIANT HORSESHOE,
THEY'RE A SERIES OF 275 FALLS

DROPPING 260 FEET INTO A NARROW
CHASM.

NEARLY TWO MILES ACROSS, THE
IGUAZU FALLS ARE WIDER THAN THE

VICTORIA FALLS AND DWARF
NIAGARA.

IN THE WET SEASON, UP TO THREE
MILLION GALLONS FLOW OVER THE

EDGE EVERY SECOND, 18,000
OLYMPIC SWIMMING POOLS EVERY

HOUR.

BLACK VULTURES GATHER.

THEY KNOW THAT ANYTHING SWEPT
OVER THE EDGE WILL BE DASHED ON

THE ROCKS BELOW, AN EASY MEAL ON
TAP.

HUGE FLOCKS OF GREAT DUSKY
SWIFTS SWIRL THROUGH THE MIST.

THEY'VE COME TO BREED.

BUT THEY HAVE A PROBLEM.

THE LUSH FORESTS THAT CLOAK THE
FALLS ARE FULL OF THIEVES.

TOUCANS, SPECIALIST NEST
RAIDERS.

AND COATIS, THEY'LL EAT ANYTHING
THEY CAN FIND, BUT EGGS ARE A

PARTICULARLY VALUABLE PRIZE.

BANDS PATROL EVERY LEVEL OF THE
FOREST.

THE SWIFTS HAVE COME UP WITH AN
EXTRAORDINARY SOLUTION.

AS DUSK ARRIVES, THEY FLY EVER
CLOSER TO THE FALLS, LOOKING FOR

A CHANCE TO PENETRATE THE
THUNDERING CURTAIN OF WATER.

THEN, ONE-BY-ONE, THEY SWOOP
THROUGH.

ONCE THEY'VE MADE IT TO THE
SLIPPERY CLIFF FACE, THEIR LONG

CLAWS ENABLE THEM TO CLING ON.

THEN THEY CLAMOR TOWARDS THEIR
NESTS, AND PRECIOUS EGGS ARE

SAFELY DEPOSITED OUT OF DANGER'S
REACH.

WHEN WE RETURN, WHY THIS NIGHT
STALKER TOPS THE LIST OF

CREEPIEST CRAWLERS IN THE
AFRICAN TROPICS.

FIND OUT WHEN "EARTH ODYSSEY"
RETURNS.

.

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

[MUSIC]

DYLAN: AS NIGHT DRAWS IN ON THE
ISLANDS OF ZANZIBAR, THE WORLD'S

BIGGEST CREEPY-CRAWLY REVEALS
ITSELF.

WEIGHING IN OVER
EIGHT-AND-A-HALF POUNDS WITH A

LEG SPAN UP TO THREE FEET, THE
COCONUT CRAB IS THE PLANET'S

LARGEST LAND-LIVING
INVERTEBRATE.

IT'S ACTUALLY A GIANT HERMIT
CRAB.

WHILE IT'S YOUNG, IT CARRIES
ANOTHER CREATURE'S ABANDONED

SHELL ON ITS BACK FOR
PROTECTION.

BUT ONCE FULLY GROWN, IT
DEVELOPS A TOUGH OUTER SKIN.

THIS CRAB STAYS HIDDEN DURING
THE DAY TO REDUCE WATER LOSS

FROM HEAT, BUT AT NIGHT, THIS
SOLITARY STALKER HEADS OFF IN

SEARCH OF ITS FAVORITE FOOD.

UNLIKE MOST OF ITS RELATIVES,
THE COCONUT CRAB CAN'T SURVIVE

IN WATER.

IT WOULD DROWN IF SUBMERGED.

ITS GILLS HAVE EVOLVED TO WORK
LIKE LUNGS, ALTHOUGH THEY NEED

TO BE KEPT MOIST IN ORDER TO
FUNCTION.

ITS ANTENNAE HAVE ALSO EVOLVED,
ENABLING IT TO PICK UP AIRBORNE

SCENTS THE SAME WAY INSECTS DO.

THIS FOREST FORAGER, ALONG WITH
OTHERS, IS ON TO SOMETHING.

ALSO KNOWN AS THE ROBBER CRAB,
OR PALM THIEF, COCONUT CRABS ARE

GREAT CLIMBERS.

THEY CAN CUT DOWN COCONUTS BY
THEMSELVES; HOWEVER, FALLEN

FRUITS ARE QUICKLY SEIZED UPON.

ALTHOUGH THE SURROUNDING SEA IS
A NO-GO ZONE FOR THESE

LAND-BASED GIANTS, IT WASN'T
ALWAYS THAT WAY.

THEY STARTED LIFE IN THE WATER.

A FEMALE COCONUT CRAB MAKES HER
WAY TO THE SHORE.

SHE'S BEEN CARRYING A BATCH OF
EGGS GLUED TO HER ABDOMEN FOR

TWO MONTHS.

AT HIGH TIDE, THEY'RE READY TO
BE RELEASED.

ON CONTACT WITH WATER, THE EGGS
HATCH IMMEDIATELY.

THE JUVENILE GIANTS EVENTUALLY
MAKE THEIR WAY ASHORE, WHERE

THEY LIVE A HERMIT'S LIFE BEFORE
BECOMING PERMANENT DRY LAND

RESIDENTS.

THANK YOU ALL SO MUCH FOR
JOINING US ON OUR TREK TO THE

TROPICAL TERRAINS OF THE PLANET.

FROM THE ISLANDS OF THE
CARIBBEAN TO THE COAST OF

AFRICA, THESE REGIONS SPAN THE
GLOBE AND HOST AN ARRAY OF

UNBELIEVABLE WILDLIFE.

WE'LL SEE YOU NEXT TIME FOR
ANOTHER "EARTH ODYSSEY".
