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 AND THIS IS "EARTH

ODYSSEY".

TODAY, WE TRAVEL AROUND THE
WORLD TO DISCOVER THE ODDEST

ANIMALS IN THE WILD.

WE'LL BEGIN IN RUSSIA WHERE THIS
STRANGE LOOKING ANTELOPE SPECIES

KNOWS HOW TO STAY SAFE.

THEN WE HEAD TO THE COAST OF
SOUTH AFRICA WHERE THIS MASTER

OF CAMOUFLAGE REALLY STANDS OUT.

AND LATER, IT'S A SPECIAL
DELIVERY FOR THESE MALE

SEAHORSES.

PLUS, THIS SHOCKING SYMBIOTIC
RELATIONSHIP KEEPS THESE SPECIES

SAFE FROM PREDATORS AND FROM
EACH OTHER.

[MUSIC]

DYLAN: THE THEORY OF NATURAL
SELECTION MAKES PERFECT SENSE

WHEN EXPLAINING WHY GIRAFFES
HAVE LONG NECKS OR WHY

CHAMELEONS CHANGE COLOR TO MATCH
THEIR ENVIRONMENT.

BUT ON THE OTHER HAND, THERE ARE
MANY SPECIES THAT HAVE BAFFLED

SCIENTISTS FOR CENTURIES, LIKE
THE MYSTIFYING MAMMALS YOU'RE

ABOUT TO MEET THAT LOOK ABOUT AS
ODD AS THEY ACT.

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, MUCUS, AND GLANDS.

WHICH NOT ONLY WARM UP IN HAILED
WINTER AIR, BUT ALSO FILTER OUT

DUST DURING THE ARID SUMMER
MONTHS.

AN ESSENTIAL ADAPTATION OF THE
STEP 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.

[MUSIC]

DYLAN: 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.

[MUSIC]

DYLAN: 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 HEAD TO THE COAST
WHERE THIS SPECIES OF OCTOPUS

DOES EVERYTHING SHE CAN TO KEEP
HER HEAD ABOVE WATER IN THESE

UNFORGIVING REEFS.

AND LATER, THE RELATIONSHIP
BETWEEN THIS UNUSUAL DUO IS

MAKING WAVES IN THE REEFS OF
SOUTH AFRICA.

PLUS, A GENDER REVEAL WITH A
TWIST.

.

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

[MUSIC]

DYLAN: IN THE ANIMAL WORLD,
IMAGE CAN BE EVERYTHING.

AMONG THE OCEAN'S COUNTLESS
SPECIES, MANY SEEK TO STAND OUT

WITH THEIR STRIKING LOOKS.

BUT OTHERS USE THEIR APPEARANCE
TO STAY OUT OF SIGHT.

AS THE TIDE GOES OUT ALONG THE
SOUTH AFRICAN COAST, VAST ROCK

POOLS BEGIN TO EMERGE.

THE RETREATING WAVES LEAVE
BEHIND COUNTLESS SEA CREATURES,

NOW TRAPPED IN THE POOLS.

THEY COME IN ALL SHAPES AND
SIZES AND MOST RELY ON THE ROCKS

AND THE CREVICES TO HOLE UP
UNTIL THE TIDE RETURNS.

BUT ONE IS HIDING IN PLAIN
SIGHT.

THE OCTOPUS IS A MASTER OF
CAMOUFLAGE.

THE COLOR AND TEXTURE OF ITS
SKIN CAN QUICKLY CHANGE TO MATCH

ITS SURROUNDINGS.

AN ESSENTIAL ADAPTATION FOR
AVOIDING PREDATORS.

BUT ALSO, AMBUSHING PREY.

THIS FEMALE IS ON THE LOOKOUT
FOR ANY CRABS UNFORTUNATE ENOUGH

TO SHARE THE SAME ROCK POOL AS
HER.

SHE JETS HERSELF AT SPEEDS UP TO
25 MILES PER HOUR, BY RAPIDLY

DRAWING WATER INTO HER MANTLE
AND EXPELLING IT THROUGH A

TUBE-LIKE SYPHON.

AND HER LACK OF BONES ENABLES
HER TO FIT IN EXTREMELY SMALL

SPACES.

THERE'S NOWHERE TO HIDE FROM
THIS RELENTLESS PREDATOR.

BEFORE LONG, SHE'S CLEANED OUT
THE ROCK POOL, BUT SHE'S STILL

HUNGRY.

IT WILL BE HOURS BEFORE THE TIDE
COMES IN.

LUCKILY, THE OCTOPUS HAS ANOTHER
EVEN MORE UNUSUAL ABILITY TO

HELP AVOID THE WAIT.

CLIMBING OUT OF THE WATER,
POWERFUL TENTACLES HELP HER

MANEUVER ACROSS THE ROCKS AND
SHELLS.

SHE KNOWS THAT THE NEARBY POOLS
STILL HAVE PLENTY TO OFFER.

NOTHING WILL COME BETWEEN THIS
EXTRAORDINARY PREDATOR AND HER

PREY.

THE OCTOPUS IS HAPPY BEING A
FISH OUT OF WATER.

BUT SOMETIMES CREATURES APPEAR
SO OUT OF PLACE IT SEEMS NATURE

HAS MADE A MISTAKE.

HERE IN THE HEART OF SOUTH
AMERICA, AMID THE FLOODED

FORESTS OF THE RIO NEGRO LIVES
ONE OF THE WORLD'S MOST UNUSUAL

CREATURES.

THE SLOTH.

IT MIGHT HAVE A UNIQUE
APPEARANCE BUT IT'S NOT JUST ITS

FEATURES THAT SET IT APART.

SLOTHS ARE ALSO THE SLOWEST
MAMMALS ON EARTH.

[MUSIC]

DYLAN: THIS THREE-TOED SLOTH
TRAVELS AT A TOP SPEED OF SIX

AND A HALF FEET PER MINUTE
THROUGH THE TREES.

HE'S SO SEDENTARY THAT ALGAE
GROWS ON HIS FURRY COAT, GIVING

HIM A GREENISH TINT, WHICH IS
USEFUL CAMOUFLAGE IN THE CANOPY.

HE'S BUILT FOR LIFE IN THE
TREETOPS, SPENDING NEARLY ALL

HIS TIME HANGING FROM THE
BRANCHES WITH A POWERFUL GRIP,

AIDED BY HIS LONG CLAWS.

BUT HEAVY RAIN BEGINS TO FALL
ACROSS THE AMAZON AND THE SPRING

FLOODWATERS HAVE ALREADY BEGUN
TO RISE.

THOUSANDS OF SQUARE MILES OF
RAINFORESTS ARE EVENTUALLY

FLOODED.

AND DESPITE THE DANGERS, HE'S
BEEN FORCED TO BRAVE THE WATERS

IN SEARCH OF A NEW HOME.

[MUSIC]

DYLAN: A SLOTH MAY BE SLOW AND
CUMBERSOME IN THE TREES, BUT

THEY'RE SURPRISINGLY CAPABLE
SWIMMERS.

DUE TO THEIR INCREDIBLY SLOW
DIGESTIVE RATE, ALL SLOTHS BOAST

AN ENORMOUS MULTICHAMBERED
STOMACH.

THIS BIG BAG OF FERMENTING
LEAVES CREATES A LOT OF GAS,

ACTING AS A GIANT FLOTATION
DEVICE.

AND THE LONG ARMS MAKE EFFECTIVE
PADDLES.

HE MOVES THREE TIMES FASTER THAN
ON LAND.

BUT NOT FAST ENOUGH TO GO
UNNOTICED.

THE GREEN ANACONDA IS A
FORMIDABLE AMAZON PREDATOR.

OFTEN CATCHING LARGE CAPYBARA
AND THE OCCASIONAL CAYMAN.

SO A VULNERABLE SLOTH IS AN
OPPORTUNITY TOO GOOD TO MISS.

[MUSIC]

DYLAN: FINALLY, HE MAKES IT TO
A SUITABLE TREE AND MAKES THE

LONG CLIMB TO SAFETY.

COMING UP, WE DISCOVER WHY THE
RELATIONSHIP BETWEEN SEA

ANEMONES AND CLOWNFISH IS NO
LAUGHING MATTER.

BUT FIRST, THE PREGNANCY FOR
THIS SPECIES OF SEA FISH MAY BE

UNUSUAL BUT WE'LL FIND OUT WHY
IT'S PERFECT FOR THIS GROWING

FAMILY.

.

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

[MUSIC]

DYLAN: FOR CENTURIES, SAILORS
HAVE WARNED EACH OTHER ABOUT

MYTHICAL SEA CREATURES LIKE
MERMAIDS, SIRENS, AND THE KILLER

KRAKEN.

AND EVEN THOUGH MORE THAN 80
PERCENT OF THE EARTH'S OCEANS

ARE UNMAPPED, UNOBSERVED, AND
UNEXPLORED, IT'S SAFE TO BET

THAT WE WON'T BE RUNNING INTO
THOSE MONSTERS.

BUT THAT DOESN'T MEAN THAT THE
OCEANS AREN'T FULL OF BIZARRE

ODDITIES.

FOR INSTANCE, THE SEAHORSE.

IT'S A FISH WITHOUT SCALES
THAT'S NOT VERY GOOD AT

SWIMMING.

AND TO TOP IT OFF, THE MALES
HAVE A VERY UNIQUE BURDEN TO

CARRY AND IT'S NOT WHAT YOU'RE
EXPECTING.

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

AND DOING THINGS DIFFERENTLY MAY
JUST BE THE SECRET TO THEIR

SUCCESS.

[MUSIC]

DYLAN: 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.

[MUSIC]

DYLAN: 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 STRAIGHT AWAY, AND

THEREFOR, 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.

[MUSIC]

DYLAN: 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.

COMING UP, THE FATAL TOUCH OF
THESE ANEMONES IS NO LAUGHING

MATTER, UNLESS YOU'RE A
CLOWNFISH.

.

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

[MUSIC]

DYLAN: OFF THE COAST OF SOUTH
AFRICA IS THE SODWANA REEF

SYSTEM.

IT'S HOME TO ANOTHER SEA
CREATURE WITH AN UNCONVENTIONAL

ADAPTATION.

WITH MORE THAN 1,000 SPECIES OF
FISH, THIS REEF IS ONE OF THE

HEALTHIEST AND MOST DIVERSE IN
EXISTENCE.

BUT SPACE IS HIGHLY SOUGHT AFTER
IN THIS OVERCROWDED ECOSYSTEM

AND DANGER CAN COME FROM ANY
DIRECTION, SO ONE REEF RESIDENT

HAS HAD TO THINK OUTSIDE THE BOX
WHEN CHOOSING A HOME.

ACROSS THE CORAL'S VAST COLONIES
OF ANEMONES SWAY WITH THE

CURRENT.

THEY MAY BE SIMPLE SEA
CREATURES, BUT THEY ARE FAR FROM

HARMLESS.

HUNGRY FISH MIGHT BE TEMPTED BY
THEIR ALLURING, SOFT TENTACLES.

BUT THE SLIGHTEST TOUCH WILL
TRIGGER THEM, FIRING A

HARPOONLIKE FILAMENT INTO THEIR
PREY.

INJECTING A PARALYZING
NEUROTOXIN.

THE HELPLESS VICTIM IS THEN
GUIDED INTO THE MOUTH BY THE

TENTACLES, TO MEET A GRISLY END.

MOST SEA CREATURES KNOW TO GIVE
THE ANEMONES A WIDE BIRTH.

BUT ONE SPECIES CHOOSES TO
IGNORE THE WARNING SIGNS.

[MUSIC]

DYLAN: UNLIKE ALL OTHER FISH ON
THE REEF, THESE CLOWNFISH DON'T

APPEAR TO BE PHASED BY THE
STINGING TENTACLES.

IN FACT, THEY'RE COMPLETELY
IMMUNE TO THE TOXINS THE

ANEMONES PRODUCE, THANKS TO A
MUCUS LAYER COVERING THEIR

BODIES.

CONSEQUENTIALLY, THEY HAVE
DEVELOPED A UNIQUE SYMBIOTIC

RELATIONSHIP.

THEY REMOVE ANY PARASITES AND
DRIVE AWAY INTRUDERS FROM THEIR

HOME WHILE THE ANEMONE PROVIDES
SHELTER FOR THE CLOWNFISH, AS

WELL AS PROTECTION FROM THEIR
PREDATORS.

IT'S AN UNUSUAL ALLIANCE BUT ONE
WHERE BOTH PARTIES REAP THE

BENEFITS.

IN THIS TIME, FEMALES WILL LAY
UP TO 1,000 EGGS NEARBY AND THE

MALE WILL STAND GUARD UNTIL THEY
HATCH.

[MUSIC]

DYLAN: THANKS TO THEIR
EXTRAORDINARY IMMUNITY, THEIR

YOUNG WILL GROW UP IN A SAFE
ENVIRONMENT AND EVENTUALLY FIND

ANEMONES OF THEIR OWN TO CALL
HOME.

THANK YOU FOR JOINING US ON THIS
ADVENTURE AROUND THE WORLD TO

DISCOVER SOME OF EARTH'S MOST
FASCINATING ANIMAL ODDITIES.

AS WE'VE SEEN, SOMETIMES THE
TRAITS THAT SET US APART FROM

THE HERD ARE ALSO WHAT MAKE US
THRIVE.

WE'LL SEE YOU FOR ANOTHER
ADVENTURE ON THE NEXT "EARTH

ODYSSEY".

[MUSIC]
