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.

LET'S EXPLORE THE WORLD TOGETHER
ON TODAY'S "EARTH ODYSSEY".

TODAY, WE'LL SPEND TIME WITH THE
MOST SKILLED SURVIVAL

SPECIALISTS IN THE ANIMAL
KINGDOM.

LIKE THESE ORCAS, WHOSE UNIQUE
TRAPPING TECHNIQUE MEANS A MEAL

IS NEVER OUT OF REACH.

WE'LL DISCOVER THE AMAZING
ADAPTATION THAT ALLOWS THIS

WEASEL TO THRIVE FROM SEASON TO
SEASON.

AND LATER, THIS BROWN BEAR IS
THE PERFECT EXAMPLE OF HOW IT

TAKES A LOT OF HEART TO SURVIVE
THE WINTER.

BUT FIRST, WE'LL TAKE A LOOK AT
AN UNUSUAL CREATURE WHO HAS

LEARNED TO SWIM WHERE THERE'S NO
WATER.

ALL OF THIS AND MORE ON TODAY'S
"EARTH ODYSSEY".

[MUSIC]

DYLAN: THE MOST SKILLED WILD
SURVIVORS ALL SHARE ONE CRITICAL

ATTRIBUTE, THE ABILITY TO ADAPT
TO THEIR SURROUNDINGS.

FROM ENVIRONMENTS THAT ARE
BRUTALLY COLD, TO SCORCHING HOT,

THESE SURVIVAL SPECIALISTS KNOW
HOW TO KEEP A COOL HEAD WHEN THE

PRESSURE IS ON.

AND STAYING COOL IS KEY IN OUR
FIRST DESTINATION, WHERE THE

DANGER IS AS HIGH AS THE
TEMPERATURE.

AT MORE THAN THREE MILLION
SQUARE MILES, THE SAHARA DESERT

IS THE LARGEST HOT DESERT IN THE
WORLD.

WITH AN AVERAGE HIGH TEMPERATURE
ABOVE 100 DEGREES, SURPRISINGLY,

NIGHTTIME TEMPERATURES CAN DROP
BELOW FREEZING.

BUT IN THE DAY, THINGS WARM UP
RAPIDLY.

VERY RAPIDLY.

JUST A FEW HOURS AFTER SUNRISE
AND IT'S ALREADY A SCORCHING 95

DEGREES.

THE INTENSE HEAT AND CONSTANT
SANDSTORMS MAKE THIS A

TREACHEROUS PLACE TO LIVE.

BUT FOR ANIMALS ADAPTED TO THESE
EXTREME CONDITIONS, THIS HEAT IS

A VITAL SOURCE OF ENERGY.

THIS SANDFISH IS COLD-BLOODED
AND NEEDS THE SUN TO RECHARGE

AFTER A COLD NIGHT.

THE SANDFISH'S SMOOTH BODY AND
SHORT, STURDY LEGS ARE IDEAL FOR

MOVING ACROSS THE DESERT
TERRAIN.

HIS EARS AND NOSTRILS ARE ALSO
SMALL ENOUGH TO STOP SAND FROM

GETTING INTO HIS NOSE AND LUNGS.

THE SANDFISH IS PERFECTLY
DESIGNED FOR THIS EXTREME

ENVIRONMENT.

BUT SO IS ITS DEADLY ENEMY.

THE HORNED VIPER IS A FEARSOME
PREDATOR WITH A TASTE FOR

SANDFISH.

MOST ANIMALS STRUGGLE TO MOVE
ACROSS THE SANDY DUNES.

BUT THE HORNED VIPER HAS
DEVELOPED THE PERFECT TECHNIQUE

TO TRAVEL ACROSS THE BURNING
SAND AT HIGH SPEED.

TO AVOID SINKING, IT GRIPS WITH
TWO POINTS OF ITS LONG BODY,

REPEATEDLY THROWING THE REST OF
ITSELF SIDEWAYS.

PRODUCING THE SMOOTH MOVEMENT
THAT GIVES THE SNAKE ITS

NICKNAME: THE SIDEWINDER.

THIS TECHNIQUE ALSO PREVENTS IT
FROM OVERHEATING, KEEPING AS

MUCH OF ITS BODY OFF THE SEARING
GROUND AS POSSIBLE.

BUT RIGHT NOW, HE SMELLS PREY.

THE SANDFISH APPEARS UNABLE TO
MOVE.

HE IS STILL WARMING UP HIS BODY
AS HIS NEMESIS NEARS.

THE SANDFISH KNOWS HE HAS NO
CHANCE OF OUTRUNNING THE VIPER.

THE SNAKE TAKES HIS TIME AS HE
PREPARES TO STRIKE.

THE OUTCOME APPEARS INEVITABLE,
BUT THE SANDFISH HAS A SECRET

WEAPON FOR SURVIVING IN THE
DESERT.

DISAPPEARING INTO THE SAND, THE
LIZARD ESCAPES THE VIPER'S

DEADLY FANGS.

IT'S THIS INCREDIBLE TRICK THAT
GIVES THE SANDFISH ITS NAME.

LITERALLY SWIMMING THROUGH THE
SAND TO SAFETY.

HIS STREAMLINED BODY AND SMOOTH
SKIN MEANS HE CAN TRAVEL WITH

GREAT SPEED UNDER THE DESERT,
AWAY FROM HIS ENEMIES.

LEAVING THE VIPER TO CONTINUE
HIS SEARCH FOR BREAKFAST.

COMING UP, WE'LL SEE HOW THESE
BROWN BEARS BEAT THE COLD BY

HIBERNATING.

THEN, IN THE WILDS OF FINLAND,
WE'LL SEE HOW ONE SMALL

PREDATOR'S LOOK CHANGES WITH THE
SEASONS.

AND HOW THIS MARINE MAMMAL USES
ITS HEAD TO HUNT WHEN THE ODDS

ARE STACKED AGAINST IT.

ALL OF THIS AND MORE COMING UP
ON "EARTH ODYSSEY".

.

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

[MUSIC]

DYLAN: WHAT MAKES ANIMALS SUCH
INCREDIBLE EXPERTS AT SURVIVING

IN THE WILD IS THEIR CREATIVITY.

FINDING UNIQUE WAYS TO THRIVE IS
THE KEY TO SUCCESS FOR EVERY

CREATURE, BIG AND SMALL.

FOR EXAMPLE, ONE OF THE BIGGEST
ANIMALS IN THE TAIGA OF NORTH

AMERICA HAS DEVELOPED ITS OWN
SPECIAL WAY TO SURVIVE THE

EXTREMES OF WINTER.

AFTER FOUR LONG MONTHS,
TEMPERATURES HAVE FINALLY RISEN

ABOVE FREEZING.

AND THIS IS THE FIRST BROWN BEAR
TO EMERGE.

WEIGHING ALMOST 1,100 POUNDS,
BROWN BEARS ARE OMNIVORES AND

WILL EAT ANYTHING.

BUT THERE WAS LITTLE TO CHOOSE
FROM HERE IN WINTER.

SO, IN ORDER TO SURVIVE, HE HAS
CONSERVED HIS ENERGY SLEEPING

RIGHT THROUGH THE COLDEST PART
OF THE YEAR.

FOR UP TO SIX MONTHS, BROWN
BEARS DIG DENS OR HIDE

THEMSELVES AWAY IN CAVES TO
HIBERNATE.

THEY REDUCE THEIR HEARTRATE FROM
50 TO 10 BEATS PER MINUTE.

SLASHING THEIR METABOLIC RATE.

THE BROWN BEAR CAN SURVIVE FOR
100 DAYS WITHOUT FOOD OR WATER.

BUT NOW, SPRING HAS FINALLY
SPRUNG.

THE HUNGRY BEAR HAS WOKEN UP.

THE SNOW AND ICE HAVE BEGUN TO
MELT AND THE BEAR CAN START TO

LOOK FOR FOOD ONCE AGAIN.

HE'S SO HUNGRY THAT HE'LL GO FOR
ANYTHING THAT'S AVAILABLE.

BEARS HAVE ONE OF THE BEST
SENSES OF SMELL OF ANY MAMMAL.

2,000 TIMES MORE POWERFUL THAN
HUMANS.

USING SMELL ALONE, HE TRACKS
DOWN A CARCASS MORE THAN 18

MILES AWAY FROM HIS DEN.

A VICTIM OF THE COLD WINTER
PROVIDES MUCH-NEEDED SUSTENANCE.

BUT HE NEEDS TO BE QUICK, A FIND
LIKE THIS IS SURE TO ATTRACT

ATTENTION.

THERE ARE AROUND 2,500 BEARS
ROAMING NORTHERN EUROPE'S

FORESTS.

AND MOST WILL BE HUNGRY.

AT FIRST, HE'S TOO BUSY TO
NOTICE HE'S GOT COMPANY.

LUCKILY, BEARS HAVE GREAT
HEARING.

THE THAWING ICE GIVES THE
INTRUDER'S GAME AWAY.

THE INTRUDER IS MUCH BIGGER, SO
HE MAKES A SWIFT EXIT.

LUCKILY, THERE WILL BE PLENTY OF
FOOD LEFTOVER.

HE JUST HAS TO WAIT HIS TURN.

COMING UP, HOW THIS CREATURE'S
STYLE IS NEVER OUT OF SEASON.

AND WE'LL SEE THE ULTIMATE
HUNTING TECHNIQUE THAT HAS BEEN

PASSED DOWN FOR GENERATIONS.

ALL COMING UP NEXT ON "EARTH
ODYSSEY".

.

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

[MUSIC]

DYLAN: SOME AMAZING ANIMALS CAN
ACTUALLY CHANGE THEIR PHYSICAL

APPEARANCE TO BLEND INTO THEIR
SURROUNDINGS.

THESE COLOR-CHANGING CREATURES
HAVE QUITE THE ADVANTAGE IN THE

WILD.

THE SKIN OF A CHAMELEON OR
OCTOPUS CAN CHANGE RAPIDLY TO

CAMOUFLAGE FROM PREDATORS.

WHILE OTHER COLOR-COORDINATORS
ARE MORE SUBTLE, ALTERING THEIR

LOOK OVER THE COURSE OF THE
SEASONS.

JUST LIKE THIS FURRY BUT
FEROCIOUS FINNISH NATIVE.

HERE IN FINLAND, ONE ANIMAL USES
A TRAIT TO SURVIVE

THE EXTREME CHANGES BETWEEN THE
SEASONS.

THE WEASEL.

THE WORLD'S SMALLEST CARNIVORE.

AT AROUND SIX INCHES LONG, IT
HAS A CUTE, HARMLESS APPEARANCE.

BUT LOOKS CAN BE DECEPTIVE.

[MUSIC]

DYLAN: AND EVOLUTION HAS GIVEN
THEM A WEAPON.

WEASELS CHANGE THEIR COLOR
ACCORDING TO THE SEASONS.

IN THE SUMMER, WEASELS HAVE A
BROWN COAT.

AND IN WARMER REGIONS, WHERE
SNOW IS SCARCE, THEY STAY THIS

COLOR.

BUT IN SNOW-COVERED REGIONS,
THIS CAN CHANGE TO WHITE.

THIS ABILITY TO CHANGE COLOR TO
SUIT THEIR SNOWY ENVIRONMENT

MAKES THEM HARD TO SPOT.

AND ONE CAN SMELL HIS FAVORITE
MEAL.

[MUSIC]

DYLAN: VOLES.

THESE SMALL RODENTS LIVE IN
UNDERGROUND BURROWS.

THEY USUALLY TRAVEL IN A NETWORK
OF TUNNELS BENEATH THE SNOW, BUT

SOMETIMES, THEY HAVE TO VENTURE
OUT.

UNFORTUNATELY, NATURE HASN'T
GIVEN VOLES THE SAME ABILITY TO

CHANGE COLOR, LEAVING THEM AT A
DISTINCT DISADVANTAGE.

[MUSIC]

DYLAN: THE WEASEL SPOTS THE
OPPORTUNITY AND GIVES CHASE.

[MUSIC]

DYLAN: IT CLOSES THE GAP
QUICKLY, BUT THE VOLE MAKES IT

BACK TO ITS BURROW.

IT MAY THINK IT'S SAFE, BUT THE
WEASEL'S SMALL ENOUGH TO FOLLOW

IT INTO ITS TUNNEL.

THIS HUNGRY WEASEL IS GOING TO
HAVE A BUSY WINTER.

WHEN WE RETURN, WE HEAD TO
PATAGONIA, WHERE THESE

MAGNIFICENT MARINE MAMMALS ARE
PERFECTING THEIR TRAPPING

TECHNIQUE.

.

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

[MUSIC]

DYLAN: FOR MANY ANIMALS OF THE
WILD, SURVIVAL MEANS TRAVELING

INCREDIBLE DISTANCES IN SEARCH
OF SAFETY, FOOD, AND A PLACE TO

BREED.

AND ONE OF THE MOST POPULAR
MIGRATION DESTINATIONS SITS JUST

OFF THE PACIFIC COAST OF CANADA.

VANCOUVER ISLAND IS HOME ONE OF
THE WORLD'S MOST DIVERSE

ECOSYSTEMS.

GLACIER-CAPPED MOUNTAINS,
ANCIENT FORESTS, A NETWORK OF

RIVERS AND CREEKS, AND A
NUTRIENT-RICH OCEAN THAT

SUPPORTS AN ABUNDANCE OF
WILDLIFE.

INCLUDING THE REGION'S FAMOUS
PACIFIC SALMON, ORCAS, AND OF

COURSE, THIS GENTLE GIANT.

HUMPBACK WHALES CAN REACH 52
FEET IN LENGTH AND WEIGH MORE

THAN 36 TONS, MAKING THEM THE
FIFTH LARGEST ANIMAL ON THE

PLANET.

[MUSIC]

DYLAN: THE HUMPBACK'S ENORMOUS
FRAMES ARE FUELED BY SMALL

SCHOOLING FISH LIKE HERRING.

AND SWARMS OF TINY SHRIMP-LIKE
CRUSTACEANS KNOWN AS KRILL.

THESE TOOTHLESS WHALES USE A
MASS OF BRISTLES CALLED BALEEN

PLATES TO FILTER FOOD FROM THE
WATER.

THE HUMPBACKS ARE ABOUT TO
EMBARK ON A MAMMOTH JOURNEY.

[MUSIC]

DYLAN: THEY SPEND EACH WINTER
IN THE WARMER SOUTHERN WATERS

OFF MEXICO AND HAWAII.

MORE THAN 3,000 MILES AWAY.

THIS IS WHERE THEY'LL BREED
BEFORE RETURNING TO VANCOUVER

ISLAND'S FOOD-RICH WATERS WITH
THEIR CALVES IN TOW.

BUT THERE'S ONE RESIDENT POD OF
WHALES THAT NEVER LEAVES THE

REGION AND THESE PREDATORS HAVE
A TASTE FOR VANCOUVER ISLAND'S

SPECIALTY: SALMON.

KILLER WHALES WEIGH UP TO NINE
TONS AND ROAM THE ISLAND'S COAST

IN PODS OF UP TO 30 INDIVIDUALS.

UNLIKE HUMPBACKS, THEY HAVE MORE
THAN 20 PAIRS OF POINTED,

INTERLOCKING TEETH.

ALSO KNOWN AS ORCAS, NAMED AFTER
THE ROMAN GOD OF THE UNDERWORLD,

THEY HUNT IN PACKS AND ARE OFTEN
REFERRED TO AS THE WOLVES OF THE

SEA.

BUT THIS PARTICULAR POD POSES NO
THREAT TO THE SALMON.

THESE KILLER WHALES HUNT
MAMMALS.

WHILE THE RESIDENT PODS OF ORCAS
EAT ONLY FISH, THIS VISITING

GROUP GOES FOR MUCH LARGER PREY,
SUCH AS SEA LIONS.

THESE SEA LIONS WERE LUCKY TO
GET AWAY.

ORCAS CAN BE FOUND ALL AROUND
THE WORLD, A TESTAMENT TO THEIR

ABILITY TO SURVIVE IN AN ARRAY
OF DIFFERENT ENVIRONMENTS.

IN EVERY OCEAN ON EARTH, PODS OF
ORCA ALL DEVELOP THEIR OWN

UNIQUE HUNTING TECHNIQUES.

BUT THIS PATAGONIAN SHORELINE IS
ONE OF ONLY TWO PLACES IN THE

WORLD WHERE ORCAS HAVE LEARNED
TO PURPOSEFULLY STRAND

THEMSELVES AS THEY ATTEMPT TO
CATCH SEAL PUPS PLAYING ON THE

BEACH.

[MUSIC]

DYLAN: IN BREEDING SEASON, THIS
AMBUSH TACTIC IS HIGHLY

SUCCESSFUL.

BUT THEY DON'T ALWAYS GET IT
RIGHT.

AND THE ORCA RISK DEATH IF THEY
ARE UNABLE TO WRIGGLE BACK INTO

DEEPER WATER.

THE ORCAS, HOWEVER, HAVE THE
INTELLIGENCE TO KNOW THAT THIS

IS A HIGH-RISK STRATEGY.

SO, TODAY, EVEN BEFORE THE SEAL
PUPS HAVE BEEN BORN, THESE ORCA

HAVE GATHERED HERE FOR A
TRAINING SESSION.

THE ORCA ARE WAITING NEAR THE
ENTRANCE TO A LAGOON.

THEY KNOW THIS AREA HAS A LARGE
TIDAL RANGE.

GRADUALLY, THE ATLANTIC WATERS
FLOOD A HIDDEN CHANNEL.

ALLOWING THE ORCAS TO SWIM IN.

[MUSIC]

DYLAN: ONCE INSIDE THE LAGOON,
THE BIGGEST ORCA NOW

DEMONSTRATES HOW TO TIME ITS
ATTACK WITH THE SURGE OF A WAVE.

WAITING FOR THE NEXT WAVE TO
MANEUVER BACK INTO DEEPER WATER.

[MUSIC]

DYLAN: THE YOUNG ORCAS ARE THEN
FORCED TO PRACTICE THIS BEACHING

TECHNIQUE.

[MUSIC]

DYLAN: FOR THE ORCAS, THIS
PRACTICE MAKES PERFECT.

IT MAY BE RISKY, BUT BY
PRACTICING IN ADVANCE, THEY

DEMONSTRATE EXTREMELY HIGH
INTELLIGENCE.

ENABLING THE YOUNGSTERS TO LEARN
THIS SKILL IN A LOWER PRESSURE

ENVIRONMENT.

IT'S THIS LEVEL OF INTELLIGENCE
THAT MAKES THE OCEAN'S LARGEST

DOLPHIN ALSO ITS DEADLIEST
PREDATOR.

IN EVERY CORNER OF THE WORLD,
ANIMALS DISPLAY THEIR INGENIOUS

INSTINCTS TO SURVIVE THE WILD.

WHETHER IN SAND, SNOW, OR SEA,
SURVIVING AGAINST THE ODDS IS

JUST ANOTHER DAY IN THE LIFE FOR
THESE CREATIVE CREATURES.

THANKS FOR JOINING US AND I HOPE
TO SEE YOU AGAIN ON THE NEXT

"EARTH ODYSSEY".
