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

WATCHING TELEVISION THAT IS
EDUCATIONAL AND INFORMATIONAL.

THE MORE YOU KNOW ON NBC.

DYLAN: I'M DYLAN DREYER, AND
THIS IS "EARTH ODYSSEY".

TODAY WE'RE ON A QUEST TO FIND
THE FUNKIEST FEATURES IN THE

ANIMAL KINGDOM, LIKE THE
HIGH-CLASS HEADWEAR OF THIS

EGYPTIAN SAND-SURFING REPTILE.

AND BENEATH THE WAVES, IT TAKES
SOME UNIQUE HORSEPOWER FOR THIS

SPECIES TO LAY THEIR EGGS.

PLUS, WE HANG OUT WITH SOME
HIGH-CLIMBING CARNIVORES.

AND ELEPHANTS AREN'T THE ONLY
MAMMALS THAT USE THEIR TRUNKS TO

THRIVE IN THE WILD.

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

[MUSIC]

DYLAN: EVERY WILD SPECIES HAS
DEVELOPED SPECIFIC TRAITS THAT

HELP THEM THRIVE IN THEIR UNIQUE
ENVIRONMENTS.

THESE EVOLUTIONARY ADAPTATIONS
ARE VITAL TO THEIR SURVIVAL, BUT

THEY CAN ALSO BE THEIR DEFINING
FEATURE, SOME BIZARRE, SOME

EXTREME, BUT ALL OF THEM
FANTASTICALLY FUNCTIONAL AND

EVEN A LITTLE FUNKY.

AND THERE ARE FEW BETTER
EXAMPLES THAN THE SAIGA ANTELOPE

THAT HAVE A NOSE FOR THE
PECULIAR.

IN NATURE, MOST SPECIES HAVE
EVOLVED TRAITS AND BEHAVIORS

THAT ARE CLEARLY A RESULT OF THE
HABITAT IN WHICH THEY LIVE, BUT

THERE ARE MANY STRANGE CREATURES
THAT HAVE BAFFLED SCIENTISTS FOR

CENTURIES.

HERE IN RUSSIA LIVES ONE OF THE
MOST UNUSUAL.

THIS IS THE SAIGA ANTELOPE.

ITS LARGE, CARTOON-LIKE NOSE
RESEMBLES A SHORTENED ELEPHANT

TRUNK, BUT THERE'S MORE TO THIS
COMICAL APPENDAGE THAN MEETS THE

EYE.

ITS NOSTRILS ARE LINED WITH
HAIRS, MUCOUS, AND GLANDS, WHICH

NOT ONLY WARM UP INHALED WINTER
AIR, BUT ALSO FILTER OUT DUST

DURING THE ARID SUMMER MONTHS,
AN ESSENTIAL ADAPTATION OF THE

STEPPE, WHERE SEASONAL CHANGES
CAN BE SEVERE.

AS THE END OF SUMMER APPROACHES,
THE GRASSES THEY FEED ON HAVE

COMPLETELY DRIED OUT.

SO, THE SAIGA MUST TRAVEL FAR
AND WIDE TO FIND WATER.

AND THEY'RE IN LUCK.

THIS FRESHWATER LAKE WILL KEEP
THE HERD HYDRATED IN THE

PUNISHING HEAT, BUT THIS IS NO
TIME TO RELAX.

PREDATORS TRACK DOWN PREY WITH
EASE ON THE FLAT, OPEN

GRASSLAND.

AND THERE IS NO COVER FOR THE
SAIGA TO SEEK SHELTER.

SOMETHING APPROACHES THE WATER,
AND THE SAIGA MAKE A QUICK EXIT.

FORMING LARGE HERDS PROVIDES
SOME PROTECTION, BUT THEIR

SURPRISINGLY FAST LEGS ARE THEIR
BEST DEFENSE.

AT FULL PACE, SAIGA ARE FASTER
THAN A RACEHORSE, UP TO 50 MILES

PER HOUR.

BUT IT'S A FALSE ALARM.

THIS TIME, IT'S JUST A VERY
THIRSTY YOUNG FOX, WHICH IS NO

THREAT TO THE HERD.

THE STRANGE-LOOKING CREATURES
QUICKLY RETURN TO THE LAKE TO

QUENCH THEIR OWN THIRST.

COMING UP, WE'LL STOP OFF IN THE
PHILIPPINES TO SEE HOW THIS

QUIRKY CLIMBER STAYS COMFY IN
THE CANOPY.

THEN, WE DISCOVER HOW THIS FISH
IS A HORSE OF ANOTHER COLOR.

PLUS, HOW EGYPT'S DESERTS ARE
LITERALLY SWIMMING WITH THE

WEIRD AND WILD.

ALL OF THIS WHEN WE RETURN ON
"EARTH ODYSSEY".

.

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

DYLAN: WELCOME BACK TO "EARTH
ODYSSEY", WHERE THE JUNGLES OF

THE PHILIPPINE ISLANDS OF
PALAWAN HIDE A VERY

UNUSUAL-LOOKING CREATURE.

THIS BINTURONG IS ON THE PROWL
FOR FOOD.

WITH HIS STOCKY BODY AND SMALL,
TUFTED EARS, HE'S ALSO KNOWN AS

A BEARCAT.

BUT HE'S NOT BUILT FOR LIFE ON
THE FOREST FLOOR.

INSTEAD, HE'S MORE AT HOME IN
THE BRANCHES ABOVE.

SEMI-RETRACTABLE CLAWS MAKE
SCALING TALL TREES LOOK EASY.

HE ALSO HAS A PREHENSILE TAIL,
ONE OF ONLY TWO CARNIVORES IN

THE WORLD WITH THIS UNUSUAL
FEATURE.

THE TAIL WORKS LIKE A FIFTH
HAND, HELPING HIM GRIP, BALANCE,

AND MOVE THROUGH THE CANOPY.

BUT HIS KEEN SENSE OF SMELL IS
WHAT MAKES CANOPY LIVING A

BREEZE.

HE'S SNIFFED OUT A POTENTIAL
MEAL.

POWERFUL JAWS SHRED BARK EASILY,
REVEALING THE GRUBS HIDDEN

UNDERNEATH.

FRUIT, BIRDS, AND SMALL RODENTS
ARE ALSO ON THE MENU.

HOWEVER, HE'S CAUGHT THE SCENT
OF HIS FAVORITE SNACK, EGGS.

LONG, SENSITIVE WHISKERS AND HIS
NATURAL AGILITY HELP HIM TO

TRACK DOWN TREATS LIKE THIS
HIDDEN HIGH UP AMONG THE

BRANCHES.

IN FACT, HIS FEET WILL RARELY
TOUCH THE GROUND.

THIS BINTURONG' S ANATOMY AND
DEXTERITY MAKE HIM PERFECTLY

ADAPTED TO LIFE IN THE CANOPY.

BUT THE BEARCAT IS NOT THE ONLY
ANIMAL WITH FASCINATING FEATURES

LIVING AT HIGH ALTITUDES.

THE HIMALAYAN MOUNTAIN RANGE IS
ONE OF THE YOUNGEST ON THE

PLANET, BUT IT'S STILL A WORLD
FULL OF MYSTERY AND UNDISCOVERED

WONDERS.

AND IN THE SHADOW OF ONE OF
INDIA'S HIGHEST PEAKS, NANDA

DEVI, LIES A HIDDEN VALLEY WITH
ITS OWN UNIQUE MICROCLIMATE.

AS SPRING ARRIVES, ONE
FASCINATING CREATURE BEGINS TO

EMERGE.

NOT ALL ASIATIC BLACK BEARS
HIBERNATE, BUT IN COLDER REGIONS

SUCH AS THIS, THEY'RE FORCED TO
REMAIN IN THEIR DENS FOR UP TO

FIVE MONTHS OF THE YEAR.

HE MAY BE THE SAME SIZE AS HIS
AMERICAN COUSINS, BUT THAT'S

WHERE THE SIMILARITIES END.

HE HAS A SHAGGY BLACK COAT WITH
A DISTINCTIVE CREAMY,

CRESCENT-SHAPED MARK ON HIS
CHEST, EARNING HIM THE NICKNAME

MOON BEAR.

BUT ONE OF THE BIGGEST
DIFFERENCES IS HIS DIET.

DESPITE BEING ARMED WITH
TWO-INCH-LONG CURVED CLAWS AND

CANINE TEETH DESIGNED FOR
TEARING MEAT, THIS PREDATOR IS

PRIMARILY VEGETARIAN.

GRASSES, FRUITS, AND NUTS MAKE
UP THE MAJORITY OF HIS DIET,

ALONG WITH THE OCCASIONAL
INSECT.

AND HIS INCREDIBLY ACUTE SENSE
OF SMELL CAN DETECT HONEY FROM

MORE THAN THREE MILES AWAY.

[BEAR SNIFFING]

DURING THE AUTUMN MONTHS, THE
BEAR WILL CONSUME ACORNS,

WALNUTS, AND OTHER FRUITS THAT
HAVE A HIGH FAT CONTENT,

ENSURING HE WILL BE SUSTAINED
THROUGHOUT THE WINTER.

WHILE IT MIGHT BE AN UNUSUAL
CHOICE FOR A BEAR THIS SIZE,

GOING VEGETARIAN MEANS HE CAN
FLOURISH IN THIS ENVIRONMENT

WITHOUT EVER NEEDING TO EXPEND
ENERGY HUNTING.

WHEN WE RETURN, THIS
EYE-CATCHING FISH IS SADDLED

WITH RESPONSIBILITY.

AND LATER, THESE EGYPTIAN LOCAL
LIZARDS ARE AS MYSTERIOUS AS THE

PYRAMIDS.

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

.

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

[MUSIC]

DYLAN: THE SEAHORSE IS ONE OF
THE MOST ICONIC CREATURES IN OUR

OCEANS, AND THEY'RE ALSO ONE OF
THE MOST BIZARRE.

WITH A HEAD LIKE A STALLION,
INDEPENDENTLY MOVING EYES, A

SMALL, TOOTHLESS MOUTH, AND A
SPIRAL TAIL, THESE ANIMALS ARE

TRULY UNIQUE.

BUT SEAHORSES ALSO HAVE NO
STOMACHS, AND WHEN IT COMES TO

PRODUCING THEIR OFFSPRING, THE
REAL FUNKY FEATURES BEGIN

TO SHOW.

SOME CREATURES HAVE EVOLVED TO
REPRODUCE IN A WHOLE NEW WAY,

AND DOING THINGS DIFFERENTLY MAY
JUST BE THE SECRET TO THEIR

SUCCESS.

ON THE SOUTHERN COAST OF SOUTH
AFRICA, THE KNYSNA ESTUARY

SUPPORTS A NUMBER OF ENDEMIC
SPECIES, INCLUDING THE MOST

ENDANGERED SEAHORSE IN THE
WORLD.

THIS CAPE SEAHORSE HAS THE
SMALLEST KNOWN GEOGRAPHIC RANGE

OF ITS KIND, OCCURRING IN JUST A
HANDFUL OF ESTUARIES ALONG THE

SOUTH AFRICAN COAST.

IT'S THE ONLY SEAHORSE KNOWN TO
EXCLUSIVELY INHABIT ESTUARIES,

AND WITHIN THE SUBMERGED
VEGETATION, SOMETHING

EXTRAORDINARY IS ABOUT TO
HAPPEN.

UNIQUELY, IT'S THE MALES WHO
BECOME PREGNANT AND GIVE BIRTH

TO THE BABIES.

THIS ALLOWS THE FEMALE TO MAKE
MORE EGGS STRAIGHTAWAY AND

THEREFORE REPRODUCE QUICKER.

INTERNAL FERTILIZATION OCCURS IN
THE MALE, AND HIS POUCH TISSUES

HAVE CAPILLARIES THAT SUPPLY THE
EMBRYOS WITH OXYGEN AND VITAL

FLUIDS.

AFTER A NUMBER OF WEEKS, THE
FATHER BEGINS TO GIVE BIRTH.

BUT THIS CAN BE A LONG PROCESS
WITH CONTRACTIONS LASTING UP TO

12 HOURS.

THE YOUNG FRY WILL OFTEN GRASP
ONTO NEARBY WEEDS WITH THEIR

PREHENSILE TAILS...

...PREVENTING THEM FROM BEING
WASHED AWAY BY STRONG CURRENTS

AND WAVES.

THIS NEW FATHER WILL EVENTUALLY
GIVE BIRTH TO UP TO 200 BABIES.

AND OVER THE COMING WEEKS,
THEY'LL BRAVE THE ESTUARY WATERS

UNTIL THEY TOO ARE ABLE TO MATE.

BUT THIS IS NO TIME FOR THE
FATHER TO RELAX.

A FEW HOURS AFTER THE BIRTH, THE
FEMALE WILL DEPOSIT MORE EGGS

INTO HIS POUCH TO START THE
PROCESS ALL OVER AGAIN.

SO, A MALE COULD DELIVER BABIES
IN THE MORNING AND GET PREGNANT

AGAIN THE SAME DAY, CONTINUING
ONE OF THE MOST UNIQUE LIFE

CYCLES IN THE ANIMAL KINGDOM.

COMING UP, FOR THESE RARE
EGYPTIAN REPTILES, LIFE ON THE

SAND IS NO DAY AT THE BEACH WHEN
WE RETURN TO "EARTH ODYSSEY".

.

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

DYLAN: EGYPT IS A COUNTRY
SYNONYMOUS WITH PHARAOHS,

PYRAMIDS, AND ABOVE ALL, DESERT.

SITUATED IN NORTH AFRICA, IT IS
SURROUNDED BY TWO MAJOR SEAS.

TO THE NORTH, THE MEDITERRANEAN,
AND TO THE EAST, THE RED.

BUT THESE VAST BODIES OF WATER
PLAY LITTLE PART IN FUELING THE

HUGE ARRAY OF LIFE FOUND WITHIN
EGYPT'S SAND-COVERED CENTER.

WITH AN ANNUAL RAINFALL OF JUST
OVER 30 INCHES, OFTEN FAR LESS,

REMARKABLY, THIS REGION ALSO
LAYS CLAIM TO ONE OF THE WORLD'S

EARLIEST AND LONGEST-LASTING
CIVILIZATIONS.

ANCIENT EGYPTIANS BELIEVED THAT
CREATURES HAD POWER OVER NATURE,

CONTROLLING THE SUN, THE MOON,
THE DAY, AND NIGHT.

AND ONE IN PARTICULAR WAS SEEN
AS LORD OF THE WATER, THE KEY TO

SURVIVING THIS HARSH DESERT
LIFE.

POSSIBLY THE MOST INFLUENTIAL
CREATURE THROUGHOUT EGYPT'S

ANCIENT HISTORY IS THE SNAKE.

WITH ITS DISTINCTIVE SIDEWINDING
MOVEMENT AND UNIQUE HORN-LIKE

PROTRUSIONS, THE HORNED VIPER IS
ONE OF THE MOST EASILY

RECOGNIZABLE SNAKES OF THE
DESERT.

BECAUSE THE SAND IS LOOSE AND
OFFERS LITTLE GRIP, THE VIPER

CONTRACTS ITS MUSCLES AND FLINGS
ITS BODY SIDEWAYS.

THIS WAY, ONLY TWO POINTS OF ITS
BODY REMAIN IN CONTACT WITH THE

GROUND WHEN TRAVELING ACROSS THE
DUNES.

DESPITE GROWING TO JUST OVER 20
INCHES, HORNED VIPERS STILL PACK

A VENOMOUS PUNCH.

WITHOUT TREATMENT, A BITE CAN BE
FATAL TO HUMANS.

IT'S THOUGHT THESE HORNS MAY
PROTECT THE SNAKE'S EYES AS WELL

AS BREAK UP ITS OUTLINE AGAINST
THE DESERT TERRAIN.

SO REVERED WAS THIS SPECIES,
EGYPTIANS EVEN EMBALMED THEIR

BODIES.

THIS ACT WAS A SIGN OF DEVOTION
TO THE SNAKE GODS AND A WAY OF

EARNING THEIR PROTECTION.

PREFERRING TO HUNT AT NIGHT,
THIS INDIVIDUAL SEEKS SHELTER

FROM THE MORNING SUN.

HOWEVER, ANOTHER REPTILE IS ONLY
JUST WAKING UP.

THIS LIZARD, ALSO KNOWN AS A
SKINK, WOULD MAKE AN IDEAL MEAL

FOR A VIPER.

SHORT, STUBBY LEGS AND A THICK,
SQUARE-SHAPED BODY AREN'T

OBVIOUS ATTRIBUTES FOR SPEED.

AND WITH NOWHERE TO HIDE, THE
OUTCOME OF THIS DUEL LOOKS SET.

BUT WHAT IT LACKS IN ATHLETIC
APPEARANCE, THIS LIZARD MORE

THAN MAKES UP FOR IN STYLE.

A TORPEDO-SHAPED SNOUT, SMOOTH,
SHINY SCALES, AND PADDLE-LIKE

FEET OFFER CLUES TO ONE OF
NATURE'S GREATEST DISAPPEARING

ACTS.

NOW YOU SEE IT...

...NOW YOU DON'T.

ALSO KNOWN AS A SANDFISH, THE
SKINK LITERALLY SWIMS THROUGH

THE SAND WHENEVER FACED WITH
DANGER.

BUT IT ISN'T JUST LIZARDS THAT
UTILIZE THE DESERT'S VAST

CONCEALMENT RESOURCE.

SAND BOAS ARE ALSO BUILT FOR
BURROWING.

A STOUT BODY, SMALL EYES, AND
HARD SCALES PROTECT THEIR SKIN

FROM THE ABRASIVE SAND.

HOWEVER, THIS RELATIVELY SMALL,
NON-VENOMOUS SNAKE EMPLOYS

ANOTHER UNIQUE DEFENSE TACTIC.

TO CONFUSE PREDATORS, THE SAND
BOA LEAVES PART OF ITS BODY

EXPOSED.

IT'S HEAD-SHAPED TAIL IS ARMORED
WITH TOUGH SCALES.

THIS LESS VULNERABLE BODY PART
CAN WITHSTAND MOST ATTACKS,

GIVING THE SNAKE TIME TO REACT
OR FLEE.

JUST ONE EXTRA MOMENT CAN MAKE
ALL THE DIFFERENCE IN THE WILD

AND IS ONLY POSSIBLE BECAUSE OF
THIS UNUSUAL ADAPTATION.

THANKS FOR JOINING US AS WE
EXPLORED THE WONDERFUL WORLD OF

THE WEIRD AND THE WILD.

FROM ANTELOPE TRUNKS TO DEVIL'S
HORNS, TO SAND-DIVING SNOUTS,

THESE CRUCIAL ADAPTATIONS MAY
LOOK BIZARRE, BUT THEY ENSURE

SUCCESSFUL SURVIVAL FOR EARTH'S
MOST UNUSUAL SPECIES.

I'LL SEE YOU ON OUR NEXT
ADVENTURE RIGHT HERE ON

"EARTH ODYSSEY".
