ANNOUNCER: WHEN YOU SEE THIS
SYMBOL YOU KNOW YOU'RE

WATCHING TELEVISION THAT'S
EDUCATIONAL AND INFORMATIONAL

THE MORE YOU KNOW ON NBC

DYLAN: HEY THERE, I'M
DYLAN DREYER, AND THIS IS

STAR, AND THIS IS "EARTH
ODYSSEY."

ON TODAY'S EPISODE, WE'LL
VENTURE INTO THE JUNGLES

TO SEE A RECENTLY
DISCOVERED GROUP OF

LANGURS LONG THOUGHT
EXTINCT.

PLUS, THE GIANTS OF THE
CLEAR BLUE CARIBBEAN FIND

A SAFE HAVEN FOR THEIR
YOUNG.

AND LATER, YOU WON'T
BELIEVE HOW FAR THESE

ELEPHANTS WILL TRAVEL TO
MAKE IT TO THEIR FAMILY

REUNION.

[ELEPHANTS GRUNTING]

[MUSIC]

DYLAN: THE COWNOSE RAYS
BEHIND ME ARE NATIVE TO

THE ATLANTIC OCEAN.

GOOD THING, BECAUSE THEY
NEED PLENTY OF ROOM.

THESE RAYS ARE CALLED
SCHOOLING RAYS, WHICH

MEANS THEY WILL TRAVEL IN
VERY LARGE GROUPS, EVEN

THOUSANDS AT A TIME.

FOR THE RAYS, THERE'S
CERTAINLY MORE SAFETY IN

NUMBERS WHEN SURVIVING IN
THE WILD.

IT ALSO HELPS TO HAVE A
STRONG FAMILY WATCHING

OVER YOU, ESPECIALLY IF
THE MAJORITY OF YOUR TIME

IS SPENT FLYING HIGH IN
THE TREES LIKE THESE

MONKEYS OF VIETNAM.

TAKE A LOOK.

VIETNAM IS SITUATED ON THE
EASTERNMOST RIM OF THE

INDOCHINA PENINSULA.

TO PROTECT THEIR FAMILIES,
ANIMALS HERE TAKE

ADVANTAGE OF THE COUNTRY'S
DIVERSE LANDSCAPE.

YELLOW-CHEEKED GIBBONS ARE
BORN WITH BLONDE FUR

BUT AT AROUND TWO YEARS OLD,
IT CHANGES TO BLACK.

AND WHILE MALES RETAIN
THIS DARK COLOR FOR LIFE,

FEMALES RETURN TO BLONDE
ONCE FULLY MATURE.

40 PERCENT OF THE CAT TIEN
REGION IS BAMBOO FOREST.

COMBINED WITH TOWERING
TREES, IT'S THE PERFECT

PLACE FOR ENERGETIC
YOUNGSTERS TO SHOW OFF.

GIBBONS ARE THE BEST
BRACHIATORS, OR SWINGERS,

ON THE PLANET.

THEY CAN REACH SPEEDS UP
TO 35 MILES AN HOUR

SWINGING 50 FEET FROM
BRANCH TO BRANCH.

AFTER PLAYTIME, THIS YOUNG
PRIMATE DECIDES IT'S TIME

TO REST.

HANGING FROM ONE ARM IS A
COMMON WAY FOR GIBBONS TO

RELAX.

LONG FINGERS AND POWERFUL
LIMBS ENABLE THEM TO HOLD

ON FOR OVER AN HOUR
WITHOUT LETTING GO.

WHEN IT COMES TO FOOD,
BAMBOO SHOOTS ARE A

PARTICULAR FAVORITE.

ALTHOUGH LEAVES, FRUITS,
AND SEEDS MAKE UP MOST OF

THEIR DIET, THEY ALSO
INDULGE IN INSECTS AND THE

OCCASIONAL BIRD'S EGG.

HAVING THUMB-LIKE
OPPOSABLE TOES ALLOWS

THEIR FEET TO GRASP LIKE A
SECOND PAIR OF HANDS.

HOWEVER, THIS YOUNG GIBBON
IS STILL GETTING USED TO

THE SLIPPERY SURFACE OF
BAMBOO CANES.

YELLOW-CHEEKED GIBBONS
SPEND MOST OF THEIR LIVES

IN THE UPPER CANOPY OF THE
TREES, RARELY VENTURING

DOWN TO THE FOREST FLOOR.

VIETNAM'S LABYRINTH OF
CAVES PROVIDE A PERMANENT

SHELTER FOR ONE OF THE
MOST UNCOMMON PRIMATES IN

THE WORLD.

HA LONG BAY IN NORTHERN
VIETNAM CONSISTS OF MORE

THAN 1,600 LIMESTONE
ISLANDS AND ISLETS.

IT'S ALSO HOME TO SOME OF
THE WORLD'S LARGEST CAVES.

THESE LIMESTONE CAVERNS
PROVIDE REFUGE TO SOME OF

THE RAREST SPECIES OF
LANGURS.

THESE LANGURS WERE FIRST
DISCOVERED IN THE 1960'S,

BUT THEY ALMOST COMPLETELY
DISAPPEARED FOLLOWING THE

VIETNAM WAR AND WERE
ASSUMED TO BE EXTINCT.

BUT 30 YEARS LATER, A
SMALL POPULATION WAS

DISCOVERED LIVING IN THE
CAVES OF THESE LIMESTONE

FORESTS.

THERE ARE BELIEVED TO BE
AROUND A THOUSAND LIVING

IN THE WILD TODAY.

LANGURS RARELY COME TO THE
GROUND, SPENDING MOST OF

THEIR DAY FEEDING IN THE
TREES.

LIKE OTHER LEAF-EATING
MONKEYS, THEY LACK CHEEK

POUCHES.

INSTEAD, THEY RELY ON A
COMPLEX MULTI-CHAMBERED

STOMACH.

THIS REQUIRES THEM TO EAT
ON A SEEMINGLY CONTINUOUS

BASIS.

MUNCHING ON SUCCULENT
LEAVES ALSO REDUCES THE

NEED TO DRINK WATER.

THE ADULTS IN THIS GROUP
TAKE A BREAK FROM FEEDING

TO INDULGE IN A LITTLE
MUTUAL GROOMING.

THIS RITUAL NOT ONLY
REINFORCES SOCIAL BONDS,

IT'S ALSO THE PERFECT WAY
TO RELAX.

BUT THESE YOUNGER MEMBERS
OF THE GROUP HAVEN'T QUITE

GRASPED LANGUR SOCIAL
ETIQUETTE.

THE ONLY WAY THESE
YOUNGSTERS KNOW HOW TO

UNWIND IS WITH A GAME OF
MONKEY TAG.

AS THEIR DAY COMES TO A
CLOSE, THE LANGURS RETURN

TO THE SAFETY OF THEIR
LIMESTONE CAVERNS.

COMING UP, FIND OUT WHERE
THESE GIANTS OF THE SEA GO

TO LAY THEIR EGGS WHEN WE
RETURN.

.

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: WELCOME BACK TO THE
BEST OF "EARTH ODYSSEY."

WHILE ANIMALS CAN'T ALWAYS
CHOOSE WHERE THEY RAISE

THEIR FAMILIES, THEY CAN
ADAPT TO THEIR

SURROUNDINGS.

PLENTY OF FOOD AND WATER
ALSO ENCOURAGE A THRIVING

ECOSYSTEM FOR WILDLIFE.

TAKE, FOR INSTANCE, THE
NUTRIENT-RICH WATERS OF

THE CARIBBEAN SEA.

FROM THE VIBRANT CORAL
REEFS TO GIANT SEAFARING

CREATURES, IT'S FILLED
WITH UNIQUE ANIMALS WHO

CALL THIS PARADISE HOME.

SEVEN THOUSAND ISLANDS
BETWEEN THE NORTH AND

SOUTH AMERICAN CONTINENTS
MAKE UP THE CARIBBEAN.

THE ISLAND THAT'S FARTHEST
SOUTH IN THE CARIBBEAN IS

CALLED TRINIDAD, THE
PERFECT NESTING GROUND FOR

AN ANCIENT OCEAN-BOUND
TRAVELER.

EVERY SPRING, THE
LEATHERBACK TURTLE SWIMS

ASHORE UNDER THE COVER OF
NIGHT.

THE FEMALE LEATHERBACKS
CROSS THOUSANDS OF MILES

IN OPEN OCEAN TO REACH
TRINIDAD'S SHORES.

IT'S TIME TO LAY HER EGGS
IN THE SAME SPOT THAT SHE

WAS BORN.

THE LARGEST TURTLES IN THE
WORLD, THESE SEAFARING

REPTILES CAN GROW TO BE
ABOUT SIX FEET, BUT THEY

CAN WEIGH AS MUCH AS A
SMALL CAR.

THE TURTLES VOLLEY FOR
POSITION.

WITH AS MANY AS FIVE
HUNDRED TURTLES COMING

ASHORE, IT'S HARD TO CLAIM
A SPOT ON THE BEACH.

TO GET THE NEST STARTED,
THE FEMALES DIG DEEP INTO

THE SAND WITH THEIR GIANT
FLIPPERS.

THIS ONE WILL MAKE THE
HOLE LARGE ENOUGH TO FIT

AT LEAST ONE HUNDRED EGGS.

TO KEEP THE EGGS SAFE, SHE
MUST BURY THEM UNDER THE

SAND.

THE TEMPERATURE OF THE
SAND DETERMINES IF SHE'LL

HAVE BOYS OR GIRLS.

IF THE SAND HEATS UP TO
MORE THAN 86 DEGREES, THE

BABY TURTLES WILL BE
FEMALE.

ANY COOLER, AND THEY'LL
PROBABLY END UP MALE.

THE WORK IS EXHAUSTING,
BUT SHE'S STILL GOT ONE

MORE TRICK UP HER SLEEVE
TO KEEP HER EGGS SAFE.

A FEW FEET AWAY, THE
MOTHER WILL DIG UP THE

SAND AGAIN, CREATING A
DECOY AND HOPEFULLY

THROWING OFF THE SCENT FOR
ANY WOULD-BE EGG ROBBERS.

WITH SO MANY TURTLES
TRYING TO REACH A NESTING

SPOT, THERE ARE USUALLY A
FEW STRAGGLERS STILL HARD

AT WORK AS DAWN BREAKS.

ONCE THEIR BABIES ARE SAFE
UNDER THE SAND, THESE

LEATHERBACK FEMALE TURTLES
WILL TURN BACK TOWARD THE

SEA, NEVER TO RETURN TO
THEIR NESTS AGAIN.

BUT THAT'S NOT THE ONLY STORY
TOLD IN THIS AREA.

THESE PROTECTED WARM
WATERS ARE NOW A NURSERY

FOR ANOTHER OCEAN
TREASURE, BABY HUMPBACK

WHALES.

THEY'RE CALLED CALVES.

FROM DECEMBER TO APRIL,
THERE ARE NEARLY THREE

THOUSAND HUMPBACKS THAT
VISIT THE SILVER BANK

NURSERY.

THE MOTHER HUMPBACK AND
HER CALF STAY CLOSE

TOGETHER, CONSTANTLY
TOUCHING EACH OTHER AS

THEY SWIM IN THE CLEAR
BLUE WATERS.

PHYSICAL CONTACT IS
IMPORTANT FOR THE BABY AND

ITS MOTHER.

FOR THE FIRST YEAR, THE
TWO WILL STAY TOGETHER.

WHEN SUMMER GETS CLOSER,
THE WHALES WILL SWIM

THOUSANDS OF MILES AWAY.

THEY HEAD NORTH TO THE
COLD ATLANTIC OCEAN WATERS

WHERE THERE ARE PLENTY OF
FISH.

IT WILL BE TEN YEARS
BEFORE THE CALF WILL FULLY

GROW TO ITS ENORMOUS SIZE.

SOME GET AS LARGE AS 52
FEET, WEIGHING AN

UNBELIEVABLE ONE HUNDRED
THOUSAND POUNDS.

THESE GIANTS OF THE SEA
HAVE LONG SOUGHT REFUGE IN

THE CALM CLEAR WATERS OF
THE CARIBBEAN, A SAFE

PLACE FOR EVEN THE LARGEST
MARINE ANIMALS.

COMING UP ON "EARTH
ODYSSEY," NO MORE

MONKEYING AROUND.

WAIT UNTIL YOU SEE HOW
THESE PRIMATES HAVE

LEARNED TO SLEEP HIGH IN
THE TREES.

.

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

DYLAN: HERE AT RIPLEY'S
AQUARIUM OF THE SMOKIES,

THESE NURSE SHARKS ARE
NOCTURNAL, OFTEN RESTING

DURING THE DAY.

THEY GET THEIR NAME FROM
THE SUCKING NOISE THEY

MAKE WHEN THEY'RE FEEDING.

THE NOISE SOUNDS A LOT
LIKE A BABY SUCKING ON A

BOTTLE, WHICH REMINDS US
OF ANOTHER ANIMAL ON THE

OTHER SIDE OF THE WORLD, A
GROUP OF YOUNG MONKEYS WHO

STICK CLOSE TO THEIR
MOTHERS, ESPECIALLY WHEN

THEY'RE FEEDING.

IT'S A SURVIVAL INSTINCT
THAT KICKS IN AT BIRTH AND

STAYS WITH THE YOUNGSTERS
UNTIL THEY'RE READY TO

BRAVE THE WORLD ON THEIR
OWN.

TAKE A LOOK.

THE TIBETAN MACAQUE IS ONE
OF THE LARGEST OF ALL

MACAQUE SPECIES.

LIKE MOST PRIMATES,
GROOMING PLAYS AN

IMPORTANT PART IN THE
LIVES OF THE TROOP.

THIS RITUAL REINFORCES
SOCIAL BONDS AND PROVIDES

A RELAXING BREAK FROM THE
DAILY GRIND.

AFTER BREAKFAST, THESE
YOUNGER MALES TAKE TIME TO

BURN OFF SOME ENERGY.

PLAYTIME FOR THESE
PRIMATES ISN'T JUST ABOUT

HAVING FUN OR TUSSLING
WITH YOUR BUDDY.

THIS IS ACTUALLY AN
IMPORTANT LEARNING TOOL,

AS ONE DAY, THESE TWO
COULD BE COMPETING OVER A

FEMALE MEMBER OF THE
TROOP.

THIS MOTHER HAS FOUND A
QUIET PLACE TO ESCAPE FROM

THE RUCKUS DOWN BELOW.

SHE'S JUST GIVEN BIRTH,
AND THIS SPOT UP IN THE

TREES PROVIDES PROTECTION
FOR HER NEW BABY.

AS TRANQUIL AS THE FOREST
SEEMS, THIS MOTHER KNOWS

THAT DANGER LURKS AROUND
EVERY CORNER.

MACAQUES ARE FOUND IN
DIVERSE TYPES OF

ENVIRONMENTS ACROSS ASIA.

THESE LION-TAILED MACAQUES
LIVE IN THE TROPICAL

FORESTS OF SOUTHERN INDIA.

THIS BABY IS THE NEWEST
ADDITION TO A MACAQUE

FAMILY LED BY A DOMINANT
MALE.

SHE WILL STAY WITH HER
TROOP ALL OF HER LIFE AND

WILL EVENTUALLY FIND HER
PLACE IN THE SOCIAL

HIERARCHY AS SHE GETS OLDER.

HOWEVER, THIS YOUNG

MALE WILL ONE DAY BREAK
AWAY FROM HIS FAMILY AND

JOIN A BACHELOR GROUP.

HE'S ALREADY SHOWING SIGNS
OF INDEPENDENCE.

THE YOUNG MALE IS LEARNING
HOW TO INVESTIGATE HIS

ENVIRONMENT TO FIND THINGS
TO EAT.

MACAQUES ARE EXTREMELY
ADAPTABLE TO THEIR

ENVIRONMENTS.

ACROSS THE ASIAN
CONTINENT, THESE CURIOUS

CREATURES LIVE OFF THE
LAND, LEARNING FROM EACH

OTHER AND NURTURING THEIR
YOUNG.

COMING UP, ONE OF THE
LARGEST POPULATIONS OF

THESE GIANTS ON EARTH.

THAT'S NEXT ON "EARTH
ODYSSEY."

.

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

DYLAN: WELCOME BACK TO THE
BEST OF "EARTH ODYSSEY."

WHERE YOU LIVE CAN DICTATE
WHAT KIND OF CHALLENGES

YOU'LL FACE GROWING UP.

LAND ANIMALS CERTAINLY
DON'T HAVE THE SAME ISSUES

AS THOSE FROM THE SEA, BUT
HOPEFULLY, THEY ALL HAVE

SOMEONE WHO WILL SHOW THEM
THE ROPES AND HELP THEM

NAVIGATE THEIR
SURROUNDINGS.

LET'S SEE HOW TWO VERY
DIFFERENT SPECIES TEACH

THE NEXT GENERATION THE
SKILLS THEY NEED TO

SURVIVE.

LOCATED JUST ABOVE THE
EARTH'S EQUATOR YOU'LL

FIND THE SMALL ISLAND
NATION OF SRI LANKA IN THE

INDIAN OCEAN.

WHAT IT LACKS IN SIZE,
THIS COUNTRY MAKES UP FOR

IN DIVERSITY.

THESE LOWLANDS ARE RULED
BY GIANTS.

ELEPHANTS LIVE IN
CLOSE-KNIT GROUPS UNDER

THE WATCHFUL EYE OF AN
OLDER FEMALE.

WITH HER YEARS OF
KNOWLEDGE AND EXPERIENCE,

THE MATRIARCH KNOWS WHERE
TO FIND FOOD AND WATER IN

TIMES OF SHORTAGE.

WITH WATER A PRECIOUS
COMMODITY, HERDS FROM

ACROSS NORTHEAST SRI LANKA
MAKE THEIR WAY TO A VAST

LAKE KNOWN AS MINNERIYA
TANK.

SOME ELEPHANTS TRAVEL
HUNDREDS OF MILES TO REACH

THIS RESERVOIR.

OFTEN, FAMILY GROUPS BAND
TOGETHER TO FORM LARGER

HERDS.

THE LAKE IS A KEY TO
SURVIVAL FOR THE ISLAND

ELEPHANTS.

EVEN AFTER WEEKS WITHOUT
RAIN, MINNERIYA TANK

OFFERS BOTH FOOD AND WATER
FOR THESE MIGRATING HERDS.

AND THE SURROUNDING SCRUB
FOREST PROVIDES

MUCH-NEEDED SHELTER FROM
THE SUN.

A THOUSAND MILES WEST OF
THE SOUTH AMERICAN COUNTRY

OF ECUADOR ARE A GROUP OF
ISLANDS CALLED THE

GALAPAGOS.

ISABELA IS BY FAR THE
LARGEST IN THE CHAIN OF

GALAPAGOS ISLANDS.

IT'S THOUGHT THAT THIS
SETTLER ON ISABELA ISLAND

WAS ONCE JUST A CALIFORNIA
DREAMER.

SCIENTISTS SAY ANCESTORS
OF THE SEA LION LEFT THEIR

NORTH AMERICAN HOME AND
SWAM NEARLY THREE THOUSAND

MILES TO ISABELA ISLAND.

GALAPAGOS SEA LIONS ARE
SMALLER THAN THEIR

AMERICAN COUSINS.

TEN FEET LONG AND WEIGHING
IN AT MORE THAN FIVE

HUNDRED 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.

[SEA LION GROWLING]

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 GROWLING]

...A COMMON BOND BETWEEN
MOTHERS AND YOUNG

WITNESSED IN SPECIES
ACROSS THE ANIMAL KINGDOM.

THANKS FOR JOINING ME ON
THIS SPECTACULAR JOURNEY

THROUGH THE GREATEST
PLACES ON EARTH.

WE'LL SEE YOU NEXT TIME
FOR ANOTHER "EARTH

ODYSSEY."
