- 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, EVERYBODY, I'M DYLAN
- DREYER.

WELCOME TO "EARTH ODYSSEY".

TODAY, WE'LL EXPLORE THE PLANET

TO FIND THE HUNGRIEST ANIMALS IN

THE WILD.

WHETHER THEY LOVE TO EAT OR LOVE

TO HUNT, THESE CREATURES ARE THE

HUNGRIEST ON EARTH, LIKE THE

BASKING SHARK, WHOSE LARGE MOUTH

WILL MAKE YOUR JAW DROP.

AND LATER, THERE'S A HUNGRY

PLANT THAT CRAVES MORE THAN JUST

A PITCHER OF WATER.

PLUS, THE LARGEST MAMMALS ON

LAND HAVE AN APPETITE THAT LASTS

ALL DAY LONG.

[MUSIC]

- DYLAN: HAVE YOU EVER BEEN SO
- HUNGRY THAT IT ALMOST MAKES YOU

ANGRY?

THE TERM FOR THAT IS "HANGRY",

AND BELIEVE IT OR NOT, THAT

FEELING TRANSCENDS SPECIES.

- TODAY, WE'RE SEARCHING FOR THE
- HUNGRIEST OF THE HUNGRY ON

EARTH, AND WE'LL BEGIN IN THE

HEBRIDES, WHERE HANGRY BABY

SEALS HOWL AND SCOWL FOR THEIR

NEXT MEAL.

- LYING JUST OFF THE WEST COAST OF
- SCOTLAND, THE HEBRIDES

ARCHIPELAGO IS MADE UP OF MORE

THAN 500 ISLAND AND ISLETS.

ISOLATION FROM THE MAINLAND HAS

MADE THE HEBRIDES THE PERFECT

BREEDING GROUND FOR MILLIONS OF

CREATURES, EARNING THE NAME

EUROPE'S LAST WILDERNESS.

EVER SINCE THEY WERE EXPOSED AT

THE END OF THE ICE AGE, THE

HEBRIDES ISLANDS HAVE BEEN A

LAND OF MYSTERY.

EARLY SAILORS RECOUNTED TALES OF

MERMAIDS WHO WOULD CALL OUT FROM

COASTAL CAVES...

...LURING THE SAILORS INTO THE

ROCKS AND INTO A WATERY GRAVE.

ALTHOUGH MERMAIDS ARE THE STUFF

OF LEGENDS, THESE EERIE CALLS

CAN STILL BE HEARD TODAY.

[SEAL SCREECHING]

GREY SEALS TAKE REFUGE IN THESE

CAVERNS.

[SCREECHING CONTINUES]

AND THEY ARE THE MOST VOCAL OF

ALL SEAL SPECIES.

HALF OF THE WORLD'S POPULATION

OF GREY SEALS LIVES ALONG THE

BRITISH COAST.

THE MONARCH ISLES ON THE OUTER

HEBRIDES CHAIN POST ONE OF THE

LARGEST GATHERINGS OF GREY SEALS

ON THE PLANET.

EACH WINTER, MORE THAN 35,000 OF

THESE SEA MAMMALS ARRIVE ON THE

ISLAND'S ISOLATED SHORES.

ALTHOUGH MOTHERS GIVE BIRTH TO

JUST ONE PUP AT A TIME, AROUND

9,000 ARE BORN HERE EVERY YEAR.

PUPS NURSE FOR JUST 18 DAYS.

THE MOTHER'S MILK IS SO RICH, IT

CONTAINS AROUND 60 PERCENT FAT.

THIS NUTRIENT-RICH MILK IS

ESSENTIAL SINCE THESE YOUNGSTERS

NEED TO PACK ON ABOUT FIVE

POUNDS A DAY.

IN AROUND THREE WEEKS' TIME,

THEIR WEIGHT MORE THAN TRIPLES.

ONCE THE PUPS ARE WEANED,

THEY'RE ABANDONED BY THEIR

MOTHERS AND LEFT TO FEND FOR

THEMSELVES.

- WITHOUT THE BURDEN OF A NURSING
- CHILD, THE MOTHER IS FREE TO

MATE AGAIN.

IN ABOUT TWO WEEKS' TIME, HUNGER

WILL DRIVE THESE ORPHANED PUPS

- INTO THE OCEAN IN SEARCH OF
- FOOD.

[SEAL GROWLING]

BULL SEALS PLAY NO PART IN THE

RAISING OF THE YOUNG.

- THEY HAVE A MORE IMPORTANT
- MISSION.

THE OLDER MALES MUST BATTLE OVER

TERRITORIAL RIGHTS AND ACCESS TO

THE FEMALE SEALS.

IT TAKES ABOUT TEN YEARS FOR THE

OLDER MALES TO BECOME LARGE AND

- STRONG ENOUGH TO STAKE THEIR
- CLAIM.

[SEAL SNARLING]

SOMETIMES AN INTIMIDATING SNARL

CAN WARD OFF A POTENTIAL RIVAL.

[SEAL SNARLING]

BUT THESE TWO WARRIORS APPEAR

TO HAVE MET THEIR MATCH.

[SEAL SNARLING]

FIGHTS BETWEEN BULL SEALS CAN

GET DOWN AND DIRTY, OFTEN

LEADING TO A SITUATION WHERE

ONLY ONE WALKS, OR SCOOTS, AWAY.

THIS MALE REALIZES HE'S NO MATCH

AND EVENTUALLY BACKS DOWN.

COMING UP, THESE GIANT FISH SURE

CAN PUT DOWN THE SEAFOOD, BUT DO

THEY EVER GET FULL?

PLUS, THE PITCHER PLANT IS ON

THE HUNT, BUT IT DOESN'T NEED TO

GO FAR TO FILL UP.

AND LATER, THESE ELEPHANTS ARE

LARGE, BUT ARE THEY IN CHARGE OF

THE FOOD CHAIN?

[BREAK]

.

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

DYLAN: THE WATERS OFF THE

HEBRIDES ARE TEEMING WITH

COUNTLESS VARIETIES OF FISH.

SO, IT'S NO SURPRISE THAT GREY

SEALS HAVE TO SHARE THIS FOOD

SOURCE WITH SOME OF THE LARGEST

SEA CREATURES ON THE PLANET.

MINKE WHALES WEIGH UP TO 15 TONS

AND CAN MEASURE UP TO 30 FEET IN

LENGTH.

- THESE MAMMOTH ANIMALS LUNGE AT
- THEIR PREY FROM BENEATH THE

SURFACE, SWALLOWING LARGE

VOLUMES OF FISH IN A SINGLE

GULP.

THE WHALES GENERALLY LIVE

SOLITARY LIVES, BUT THEY

SOMETIMES GATHER IN GROUPS OF

TEN OR MORE WHEN FEEDING.

BUT MINKE WHALES AREN'T THE ONLY

ONES LINING UP FOR THIS BUFFET.

TWENTY-FOUR SPECIES OF WHALES,

DOLPHINS, AND PORPOISES PATROL

THESE WATERS, INCLUDING

BRITAIN'S LARGEST FISH.

MEET THE BASKING SHARK.

THIS SLACK-JAWED CREATURE CAN

REACH UP TO 22 FEET IN LENGTH

AND HAS A DORSAL FIN UP TO

FOUR-AND-A-HALF FEET HIGH.

THEY'RE DRAWN TO THE HEBRIDES'

PLANKTON-RICH WATERS, WHERE THEY

REMAIN CLOSE TO THE SURFACE TO

FEED.

THESE MASSIVE SHARKS FILTER

AROUND A MILLION-AND-A-HALF

LITERS OF WATER EVERY HOUR,

TRAPPING THE TINY PLANKTON IN

THEIR ODD-LOOKING GILLS.

THE AMAZON RIVER ISLANDS ARE THE

HEART OF THE AMAZON RIVER.

MOST INSECTS IN THE AMAZON RIVER

ISLANDS HAVE NOT QUITE ADAPTED

TO THEIR AQUATIC HOME.

SOME ARE FORCED TO VENTURE

ACROSS THE WATER'S SURFACE IN

SEARCH OF DRY LAND.

IT'S A CROSSING FRAUGHT WITH

DANGER.

AROWANA LURK BENEATH.

THE FISH PATROL CLOSE TO THE

SURFACE, SCANNING FOR PREY.

NO INSECT IS SAFE.

AS THE FLOODWATERS RISE, MORE

AND MORE GET WASHED IN TO REACH.

IT'S A TIME FOR THE AROWANA TO

FATTEN UP BEFORE THE LONG DRY

SEASON RETURNS.

SOME OF THE WATERWAY'S MORE

UNUSUAL CREATURES ARE ALSO

TAKING ADVANTAGE OF THE NEW FOOD

AVAILABLE.

NEEDLEFISH LIE JUST BENEATH THE

SURFACE.

THEIR SLIM PROFILE HELPS THEM TO

AVOID DETECTION.

- THEY HUNT BY SIGHT AND ARE READY
- TO TAKE ADVANTAGE OF ANY

STRAGGLERS.

- UNLUCKY SPIDERS ARE PICKED OFF
- WITH EASE.

- CARNIVOROUS FISH ARE NOT THE
- ONLY UNDERWATER ANIMALS ENJOYING

A GLUT OF FOOD.

- COMING UP, THE HUNTING SKILLS OF
- THE PITCHER PLANT IS

PITCHER-PERFECT.

- PLUS, THESE ELEPHANTS ARE ALWAYS
- ON THE HUNT FOR THEIR NEXT MEAL,

AND IT'S ALWAYS RIGHT IN FRONT

OF THEIR NOSES.

[BREAK]

.

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

DYLAN: LET'S GET THIS STRAIGHT.

AN HERBIVORE ONLY EATS PLANTS,

AND A CARNIVORE ONLY EATS MEAT,

BUT THERE ARE CARNIVOROUS

PLANTS, AND THEY'RE SOME OF

NATURE'S MOST SKILLED HUNTERS,

LIKE THE PITCHER PLANT, WHICH

LOVES TO FEAST ON FLIES.

BUT SINCE THEY'RE ROOTED TO THE

SPOT, THESE PLANTS CAN'T BE

PICKY.

INSTEAD, THEY MUST BE STICKY.

BORNEO IS THE WORLD'S THIRD

LARGEST ISLAND.

RISING ABOVE ITS SWAMPY FORESTS

IS A VERY DIFFERENT LANDSCAPE...

...MOUNT KINABALU, MALAYSIA'S

HIGHEST MOUNTAIN.

- IT'S A HUGE PLUG OF GRANITE THAT
- PUSHED UP THROUGH THE

SURROUNDING ROCK 15 MILLION

YEARS AGO, THE GEOLOGICAL BLINK

OF AN EYE, AND IT'S STILL GOING

UP, GROWING ALMOST A QUARTER OF

AN INCH EVERY YEAR.

- REACHING MORE THAN
- TWO-AND-A-HALF MILES INTO THE

AIR, THE MOUNTAIN TOWERS ABOVE

THE LAND BELOW, AN ISLAND IN THE

SKY.

AS YOU CLIMB, THE PLANT LIFE

CHANGES.

- TEMPERATURES COOL, AND SOILS GET
- THINNER.

- PLANTS HAVE EVOLVED A
- MIND-BOGGLING NUMBER OF WAYS TO

COPE.

- SIX THOUSAND PLANT SPECIES GROW
- HERE.

THAT'S HALF OF ALL THE PLANTS

FOUND IN MALAYSIA.

A PITCHER PLANT, THE STRANGEST

OF THEM ALL.

- THESE PLANTS HAVE COME UP WITH
- AN INGENIOUS WAY TO SUPPLEMENT

THEIR DIETS.

THEY'RE CARNIVORES.

ATTRACTED TO THE SMELL OF SWEET

NECTAR, A FLY CAN'T HELP ITSELF

FROM TASTING THE PLANT'S RIM.

JUST BELOW IS A DEADLY

RESERVOIR.

FLUID FILLED WITH DIGESTIVE

ENZYMES BREAKS DOWN ANYTHING

UNLUCKY ENOUGH TO FALL IN.

THE PLANT'S RIBBED EDGE IS

DESIGNED TO MAKE INSECTS LOSE

THEIR FOOTING, BUT THE FLY TAKES

OFF IN THE NICK OF TIME.

- EVEN IF FALLEN INSECTS DO MAKE
- THEIR WAY OUT OF THE LETHAL

POOL, WITH WATERLOGGED WINGS,

THEY'D HAVE NO WAY OF ESCAPING

THE PLANT'S WICKED SPINES.

BUT PITCHER PLANTS ARE NOT JUST

AGENTS OF DESTRUCTION.

- OVER TIME, THE FLUID IN THE
- PITCHERS IS DILUTED BY

RAINWATER, AND THEY BECOME

OCCUPIED BY FLY LARVAE.

BUT THESE SQUATTERS PAY RENT.

THEY HELP BREAK DOWN THE PLANT'S

PREY AND KEEP BACTERIA AT BAY.

NOT A BAD FEE TO AVOID BECOMING

A PITCHER PLANT'S NEXT MEAL.

COMING UP, IT IS TRULY AMAZING

HOW MANY HOURS A DAY THESE

ELEPHANTS SPEND GRAZING.

[BREAK]

.

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

- DYLAN: LOCATED NEAR THE
- SOUTHERN TIP OF INDIA SITS THE

ISLAND NATION OF SRI LANKA.

ALTHOUGH IT IS ROUGHLY THE SIZE

OF PENNSYLVANIA, THIS TROPICAL

REGION IS PACKED WITH ENOUGH

WILDLIFE TO RIVAL A VAST

CONTINENT.

BECAUSE OF ITS UNIQUE CLIMATE,

YOU WILL FIND A STAGGERING ARRAY

OF CREATURES BOTH LARGE AND

SMALL.

AND THEY RANGE FROM THE FRIENDLY

TO THE FEROCIOUS.

[MONKEY GRUNTING]

FOR SUCH A SMALL COUNTRY, SRI

LANKA HAS A VERY COMPLICATED

CLIMATE SYSTEM.

- ON AVERAGE, TWO MONSOONS A YEAR
- HIT THE ISLAND, DRENCHING IT IN

TORRENTIAL RAINS FOR WEEKS ON

END; HOWEVER, FOR THE REST OF

THE YEAR, SRI LANKA'S LOWLANDS

ENDURE MONTHS OF DROUGHTS.

THIS LEAVES ANIMALS LIKE THE

ELEPHANT TO GO IN SEARCH OF

WATER.

- SRI LANKA'S LOWLAND PLAINS COVER
- MORE THAN TWO-THIRDS OF THE

ISLAND.

THIS REGION IS HOME TO OVER

2,000 WILD ELEPHANTS, ONE OF THE

BIGGEST POPULATIONS ON EARTH.

- WITH THE ARRIVAL OF DRY SEASON,
- FINDING FOOD BECOMES

INCREASINGLY DIFFICULT.

A FULLY GROWN ELEPHANT SPENDS UP

TO 16 HOURS A DAY GRAZING.

FEEDING ON THE SHORT, DRY GRASS

REQUIRES A SPECIAL TECHNIQUE.

THE ELEPHANT GRABS, TWISTS, THEN

SHAKES THE CLUMPS TO REMOVE ANY

DIRT.

- 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.

- AND WITH THE ARRIVAL OF THE
- FEMALES, MALE ELEPHANTS ARE

NEVER FAR BEHIND.

- MALE ELEPHANTS, OR BULLS,
- NORMALLY LEAD A SOLITARY

EXISTENCE, BUT DURING MATING

SEASON, THEY ARE READY FOR SOME

FEMALE COMPANIONSHIP.

- WITH THE BULLS' HORMONES RAGING,
- THEY'RE READY TO GRAPPLE WITH

OTHER MALES TO ASSERT THEIR

DOMINANCE.

[ELEPHANTS GRUMBLING]

- THE WINNER OF THIS SHOWDOWN
- STANDS TO WIN THE PICK OF THE

HERD.

[ELEPHANT GROANING]

BUT ROMANCE ASIDE, THE REAL

PULL OF MINNERIYA IS ITS

PRICELESS WATER SUPPLY.

EVERY ANIMAL NEEDS WATER TO

SURVIVE, BUT FEW ANIMALS ENJOY A

GOOD BATH QUITE AS MUCH AS

ELEPHANTS.

THEIR TRUNKS CAN PULL IN UP TO

TWO GALLONS OF WATER, WHICH THEY

USE TO HOSE DOWN THE OTHER

MEMBERS.

[WATER SPLASHING]

- WITHOUT THIS INVALUABLE WATER
- SUPPLY, YOUNG ELEPHANTS IN

PARTICULAR ARE PRONE TO

OVERHEATING AND DEHYDRATION.

- SO, A COOL DIP IN THE LAKES IS
- NOT JUST REFRESHING, IT IS

ESSENTIAL TO THEIR SURVIVAL.

THANK YOU FOR JOINING US ON OUR

JOURNEY TO FIND THE HUNGRIEST

ANIMALS IN THE WILD.

- SOME OF NATURE'S MOST
- FASCINATING FEEDERS ARE

SOMETIMES WHERE YOU LEAST

SUSPECT THEM, BUT THEY'RE ALWAYS

EXPECTED TO MAKE THE MOST OF

THEIR NEXT MEAL.

JOIN US NEXT TIME ON ANOTHER

"EARTH ODYSSEY".
