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.

WE’RE HEADED TO MEET
THE WILD, WEIRD,

AND WONDERFUL ANIMALS
OF AUSTRALIA.

THIS IS EARTH ODYSSEY.

ON TODAY’S EPISODE,
A SILENT PREDATOR

SWEEPS ACROSS THE OCEAN
FLOOR TRYING TO DEFEAT

A CRUSTACEAN ARMY.

THEN, AN AQUATIC
CREATURE SO STRANGE

SOME ZOOLOGISTS THOUGHT
IT COULDN’T BE REAL.

PLUS, A SPECTACULAR UNDERWATER
MIGRATION BRINGS OUT TWO VERY

DIFFERENT KINDS OF SWIMMERS.

AND ONLY IN AUSTRALIA WILL YOU
SEE BEACH GOERS LIKE THIS.

THIS AND MUCH MORE RIGHT
NOW ON EARTH ODYSSEY.

[MUSIC]

DYLAN: WILD ANIMALS FASCINATE
US.

AND THANKS TO MODERN TECHNOLOGY
AND BETTER EMPATHY FOR OUR

FELLOW LIVING CREATURES,
WE ARE UNLOCKING MANY

OF THEIR SECRETS.

BUT SOME THINGS REMAIN UNKNOWN.

IN AUSTRALIA, THOUSANDS OF
UNDERSEA ANIMALS GATHER IN

SHALLOW WATERS EVERY YEAR.

BUT WHEN THEY RETURN TO THE
DEEP, THEIR LIVES ARE STILL

SOMETHING OF A MYSTERY.

IN THE SOUTHERN PACIFIC OCEAN
OFF AUSTRALIA, ONE SPECIES

IS RISING FROM THE DEEP, STEP
BY STEP IN A HUGE FORMATION.

[WAVES CRASHING, MUSIC]

DYLAN: WITH MORE THAN 25 INCH
LEGS, THE JAPANESE SPIDER

CRABS ARE AMONG THE LARGEST
CRABS IN THE OCEAN.

A TOUGH OUTER SHELL IS A PERFECT
DEFENSE AGAINST PREDATORS.

BUT THIS INVERTEBRATE’S OUTER
SHELL IS TOTALLY RIGID.

SO AS THE SOFT CRAB GROWS,
THEY ALSO OUTGROW THEIR

OUTER BONY ARMOR EVERY YEAR.

NOW THEY’VE COME UP FROM
DEPTHS OF MORE THAN 2,500 FEET

TO MOLT.

ONE FEMALE HAS REACHED
THE FINAL STAGE.

HER BODY HAS BEEN PUMPING
OUT ENZYMES TO SEPARATE

THE OLD EXOSKELETON.

IT WILL TAKE HER AN
HOUR TO LITERALLY

CLIMB OUT OF HER SHELL.

MIGRATING EN MASSE, SPIDER
CRABS HAVE SAFETY IN NUMBERS.

BUT SHE’S BEEN LEFT BEHIND.

SHE NEEDS TO BE QUICK.

PREDATORS HAVE BEEN
WAITING FOR THE MIGRATION.

[TENSE MUSIC]

DYLAN: AN EASY TARGET, SHE NEEDS
TO GET BACK TO THE GROUP.

HUNGRY, SMOOTH STINGRAYS ARE
MORE THAN 13 FEET IN LENGTH.

BUT MID-MOLT, THE CRAB CAN’T
MOVE.

ANOTHER STRAGGLER.

IT’S INSTANTLY TARGETED.

IMMOBILE, THE MOLTING
CRAB COULD BE NEXT.

[SUSPENSEFUL MUSIC]

DYLAN: SHE GETS LUCKY.

SHE’S MANAGED TO WRIGGLE
FREE OF HER OLD SHELL,

BUT HER NEW, LIGHTER-COLORED
SHELL WILL TAKE DAYS TO HARDEN.

AT NEARLY 800 POUNDS, EACH
RAY WILL EAT MULTIPLE CRABS.

GETTING TO THE BOTTOM OF
THE PILE IS THE KEY SURVIVAL

STRATEGY.

CRABS THAT STILL HAVE
THEIR OLD, TOUGH SHELLS

ACT LIKE LIVING SHIELDS.

[HOPEFUL MUSIC]

DYLAN: IT TAKES 48 HOURS OF THE
ONSLAUGHT TO SURVIVE BEFORE

HER SHELL FULLY HARDENS.

THE MARCHING CRABS WILL LEAVE
BEHIND WHAT LOOKS LIKE A

GRAVEYARD.

BUT THOSE OLD SHELLS ARE A
SIGN OF A HEALTHY LIFE CYCLE.

FOR ALL WE CAN SEE IN
SHALLOW WATER, THESE CRABS

ARE SOMETHING OF A MYSTERY.

SCIENTISTS ARE NOT SURE
EXACTLY WHERE IN THE DEEP

OCEAN THE CRABS RETURN TO.

NEW RESEARCH TECHNIQUES TO
TRACK THE CRABS’ MIGRATION

HOME MIGHT BRING THE ANSWER.

COMING UP, AN EXTRAORDINARY
MIGRATION IN AUSTRALIA’S

OCEANS ATTRACTS A
SOPHISTICATED PREDATOR.

THEN, WILD WALLABIES GET
INTO A BEACHCOMBING BATTLE.

BUT IS IT ALL JUST FOR SHOW?

PLUS, WHAT HAS WEBBED
FEET, A DUCKBILL, AND

A TAIL LIKE A BEAVER?

THE ANSWER IS COMING
UP ON EARTH ODYSSEY.

NARRATOR: WE‘LL BE RIGHT BACK
TO THE MORE YOU KNOW ON NBC.

.

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

[MUSIC]

DYLAN: RAINFORESTS COVER LESS
THAN 1% OF AUSTRALIA.

BUT THOSE FORESTS ARE HOME TO
ONE-THIRD OF THE COUNTRY’S

MAMMAL AND BIRD SPECIES.

RIVERS FEED THE LUSH FOLIAGE
AND PROVIDE A HUNTING GROUND

FOR ONE OF THE BEST
EXAMPLES OF AUSTRALIA’S

EVOLUTIONARY ISOLATION.

THE PLATYPUS.

THIS AUSTRALIAN NATIVE
HAS A DUCK BILL,

WEBBED FEET, A TAIL
LIKE A BEAVER,

AND SHE LAYS EGGS.

SCIENTIFICALLY CLASSIFIED AS A
MAMMAL BECAUSE SHE ALSO NURSES

HER YOUNG.

THIS SPECIES’ EVOLUTIONARY PATH
DIVERGED FROM OTHER MAMMALS

MORE THAN 165 MILLION YEARS AGO.

THE MALES CAN BE MORE THAN 20
INCHES LONG AND ARE PERFECTLY

ADAPTED TO AN AQUATIC LIFESTYLE.

A BOTTOM FEEDER, THE
PLATYPUS CLOSES HIS EYES,

EARS AND NOSE AS HE DIVES.

BUT THIS ANIMAL ISN’T
SWIMMING BLIND.

THE PLATYPUS HAS A SUPER SENSE.

HIS UNIQUE BILL IS PACKED WITH
THOUSANDS OF ELECTRICALLY

SENSITIVE RECEPTORS.

HE USES IT TO SCAN THE
RIVERBED FOR ELECTRICAL

SIGNALS PRODUCED BY THE
MUSCLE CONTRACTIONS OF PREY,

LIKE CRUSTACEANS AND
WORMS HIDING IN THE MUD.

HE’LL STORE HIS CATCH
IN HIS CHEEK POUCHES.

THIS MALE WILL SPEND MORE
THAN 10 HOURS HUNTING,

EATING AROUND HALF HIS
BODY WEIGHT EVERY DAY.

IF ALL THESE PLATYPUS FEATURES
WEREN’T UNIQUE ENOUGH,

HE’S ALSO ONE OF THE FEW
MAMMALS ARMED WITH POISON.

PLATYPUS MALES HAVE HIND LEG
SPURS LOADED WITH VENOM TO FEND

OFF RIVALS.

ANOTHER RIVER PREDATOR IS
TRACKING HIS EVERY MOVE,

WAITING FOR THE PERFECT
MOMENT TO STRIKE.

AN AZURE KINGFISHER,
A RIVERSIDE HUNTER

AND A KEEN OBSERVER
OF THE PLATYPUS.

THE MAMMAL’S HUNTING TECHNIQUE
MAKES HIM A FISHERMAN’S

BEST FRIEND.

AS HE STIRS UP THE RIVERBED,
THE PLATYPUS FLUSHES

FISH TO THE SURFACE.

CUE THE KINGFISHER.

SCIENTISTS SAY THE ELUSIVE
PLATYPUS IS HARD TO COUNT AND

STUDY, BUT THEY KNOW PLATYPUS
NUMBERS HAVE DROPPED BY A THIRD

IN THE LAST 30 YEARS.

THIS PROTECTED RAINFOREST
IS ONE OF THE LAST PLACES

THIS UNIQUELY AUSTRALIAN
ANIMAL CAN SURVIVE.

COMING UP, HIGHLY INTELLIGENT
HUNTERS THAT WORK AS A TEAM TO

CATCH A SUMPTUOUS FISH DINNER.

AND THESE WILD ONES KNOW HOW TO
PICK THEIR BATTLES CAREFULLY.

MORE AUSTRALIAN SURVIVAL
STRATEGIES WHEN EARTH ODYSSEY

COMES RIGHT BACK.

NARRATOR: WE‘LL BE RIGHT BACK
TO THE MORE YOU KNOW ON NBC.

.

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

[MUSIC]

DYLAN: THE DAZZLING BLUE OF
AUSTRALIA’S COASTLINE IS HOME TO

ABUNDANT MARINE LIFE, BUT
UNDERNEATH THE PEACEFUL WATERS,

THE SERIOUS BUSINESS OF PREDATOR
AND PREY INVOLVES DAILY DANGER.

SOME ANIMALS SUCCEED THROUGH
SPEED AND SIZE, WHILE OTHERS

SEEK SAFETY IN NUMBERS.

AND ONE CLEVER OPERATOR
OPTS TO USE BOTH BRAINS AND

BRAWN WHILE ON THE HUNT.

THESE WILD COASTS ARE VIBRANT
HABITATS TO AUSTRALIA’S

EXTRAORDINARY CREATURES.

FROM OCEAN ICONS

AND THE UNEXPECTED,

TO THE MESMERIZING.

THIS IS SOUTHWESTERN AUSTRALIA.

AT THE TIP OF THIS
IMMENSE CONTINENT,

HEADLANDS FRAME PRISTINE
BAYS THAT PLAY HOST

TO AN ENORMOUS ANNUAL MIGRATION.

HUNDREDS OF THOUSANDS
OF AUSTRALIAN SALMON

HAVE TRAVELED MORE
THAN 2,000 MILES

FROM SOUTHEASTERN AUSTRALIA.

DESPITE THEIR NAME, THEY ARE
PART OF THE RAY-FINNED FISH

FAMILY AND NOT RELATED
TO SALMON OR TROUT.

AND AT MORE THAN 27 INCHES LONG,
THEY HAVE REACHED ADULTHOOD.

THEIR MIGRATION IS SYNCED WITH
THE PEAK OF AN EASTWARD FLOWING

CURRENT.

THE CURRENT TRIGGERS THE
HUGE SCHOOLS TO SPAWN.

AS THE EGGS ARE RELEASED, THE
CURRENT WILL CARRY THE NEXT

GENERATION TO PROTECTED
COASTAL NURSERIES IN THE EAST.

IT’S AN ANNUAL EVENT TO
EXTEND THE FISH’S BLOODLINES.

AND A POTENTIAL FEAST FOR
OTHERS.

GRAY NURSE AND COPPER SHARKS
MORE THAN 10 FEET LONG.

[TENSE MUSIC]

DYLAN: THEY’RE HEADING STRAIGHT
FOR THE MIGRATORS.

BUT THE AUSTRALIAN SALMON
ARE NO EASY TARGETS,

EVEN FOR SHARKS.

WHEN ONE FISH SENSES ITS
NEIGHBOR GETTING TOO CLOSE,

IT SPEEDS UP, THE WHOLE
SCHOOL MOVING AS ONE.

BUT IN THESE WATERS,
THERE’S ANOTHER SPECIES

THAT HUNTS THESE FISH,
AND THEY WORK AS A TEAM.

WITH LARGER BRAINS THAN
HUMANS, THESE DOLPHINS STAY IN

CONSTANT COMMUNICATION.

[DOLPHIN WHISTLES]

DYLAN: DRIVERS SPLIT FROM THE
MAIN POD,

HERDING THE FISH TOWARDS THE
BEACH.

[DOLPHIN WHISTLES]

DYLAN: IN THE SHALLOWS, THE
SCHOOL BECOMES SPLINTERED.

UTILIZING ECHOLOCATION AND
EXCEPTIONAL EYESIGHT,

THE DOLPHINS HIT THE PANICKING
FISH, AND STRAGGLERS

ARE PICKED OFF.

THEY MAY NOT ALL SURVIVE,
BUT FOR THE AUSTRALIAN

SALMON, THEIR ULTIMATE
GOAL HAS BEEN ACHIEVED.

THEIR EGGS ARE ALREADY DRIFTING
TOWARDS THEIR NURSING GROUNDS.

COMING UP, CAN YOU TELL A
WALLABY FROM A KANGAROO?

MARSUPIALS IN THE MANGROVES,
WHEN EARTH ODYSSEY COMES

RIGHT BACK.

NARRATOR: WE‘LL BE RIGHT BACK
TO THE MORE YOU KNOW ON NBC.

.

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

[MUSIC]

DYLAN: AUSTRALIA BOASTS MORE
THAN 20,000 MILES OF SHORELINE.

ITS MARINE ECOSYSTEMS ARE
AMONG THE MOST SPECIES-RICH IN

AUSTRALIA.

WHERE THE LUSH LAND MEETS THE
BEAUTIFUL CORAL SEA, ONE HABITAT

TAKES ROOT ON THE INTERTIDAL
ZONE.

MANGROVES.

THESE TREES EVOLVED TO
GROW IN SALTY CONDITIONS.

THEIR ENTIRE REPRODUCTION
IS ADAPTED TO A SEMI-AQUATIC

LIFESTYLE.

TO DISPERSE, THEY SIMPLY DROP.

PERFECTLY BUOYANT, THEY WILL
SPEND UP TO A MONTH AT SEA,

DRIFTING MORE THAN 100 MILES.

AN UNLIKELY BEACHGOER,
EASTERN GRAY KANGAROOS

HAVE LEARNED TO BENEFIT FROM
THE BOUNTY OFFERED BY THE SEA.

THE MANGROVE POD BOUNTY HAS MADE
THIS A POPULAR MARSUPIAL SPOT.

A SMALLER RELATIVE OF THE
EASTERN KANGAROO JOINS THE

BEACHCOMBERS.

THE AGILE WALLABY.

WHILE BOTH SPECIES FEED ON
THE SAME COASTAL VEGETATION,

THERE IS LITTLE INTERSPECIES
CONFLICT.

BUT THE WALLABIES BREED YEAR
ROUND, MEANING THERE’S ALWAYS

SOMEONE READY TO SHOW OFF.

IT’S A BATTLE OF STRENGTH.

FORELIMBS TO GRAPPLE
AND SCRATCH.

POWERFUL KICKS.

THE SIGNATURE MOVE.

BUT THE WALLABIES ARE
PULLING THEIR PUNCHES.

WITH NO DEFINED MATING SEASON,
THERE’S NO NEED TO GO ALL OUT.

NOCTURNAL BY NATURE, THE WALLABY
MOB RETREATS TO THE FOREST AS

THE SUN RISES.

THE KANGAROOS TAKE A DIFFERENT
APPROACH TO COOLING DOWN.

BREAKFAST OVER.

NOT ALL MANGROVE PODS
HAVE BEEN CONSUMED.

UP AND DOWN THE COAST,
THEY BEGIN TO TAKE ROOT,

KEEPING THE VALUABLE
HABITATS ALIVE.

THE ANIMALS OF THE SOUTHERN
HEMISPHERE ARE TRUE ORIGINALS.

FROM BEACHCOMBING KANGAROOS TO
THE DOLPHINS WHO MAKE A TEAM

SPORT OUT OF HERDING AUSTRALIAN
SALMON.

THANKS FOR JOINING US TODAY
ON OUR WILDLIFE ADVENTURES.

I’M DYLAN DREYER.

WE’LL SEE YOU NEXT
TIME ON EARTH ODYSSEY.
