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 THERE, I'M DYLAN
DREYER.

WE'RE DIVING HEADFIRST INTO
AN AQUATIC ADVENTURE TO SEE

THE CURIOUS CREATURES OF OUR
PLANET'S WATERWAYS.

THIS IS "EARTH ODYSSEY."

TODAY WE'RE TAKING A DEEP
DIVE INTO THE WORLD OF

WATER-LOVING ANIMALS TO SEE
THE CREATURES WHO LIVE LIFE

IN THE SPLASH ZONE.

LIKE THESE AFRICAN AVIANS
THAT USE WATER AS A WALKWAY.

AND LOVE IS ALWAYS ON THE
ROCKS FOR THIS COLLECTION OF

CRUSTACEANS.

PLUS, STICKS AND STONES
AREN'T BREAKING THE BONES OF

THIS CURIOUS CHARACTER.

BUT FIRST, ONE MARINE MOM
HAS REACHED THE END OF AN

EPIC MIGRATION.

THIS AND A WHOLE LOT MORE
COMING UP ON "EARTH ODYSSEY."

[MUSIC]

DYLAN: OUR OCEANS MAKE UP
ABOUT 70 PERCENT OF THE

PLANET'S SURFACE.

THOUSANDS OF MILES OF ROUGH,
UNFORGIVING DEEP SEAS

SEPARATE THE CALMER SHALLOWS
OF THE COASTLINES.

FEW CREATURES ARE WILLING TO
BRAVE THE DAUNTING CHALLENGE

IT IS TO CROSS THEM.

HOWEVER, ONE REPTILE HAS
MADE IT THE HALMARK OF THEIR

SPECIES TO UNDERTAKE THIS
MIGRATION, TRAVELING

THOUSANDS OF MILES TO ENSURE
THE ARRIVAL OF THEIR NEXT

GENERATION.

TAKE A LOOK.

UNDER COVER OF DARKNESS, SEA
TURTLES LAND UPON THE COAST.

THIS IS NO MISTAKE OR ERROR OF
JUDGMENT; IT'S FOR A VITAL

REASON.

AS ADULTS, THESE OCEANGOING
CREATURES RETURN TO THE

SHORES WHERE THEY WERE BORN
EVERY 2 YEARS OR SO TO BREED.

[MUSIC AND SOUNDS OF WAVES]

DYLAN: THIS GREEN SEA TURTLE
HAS JUST FINISHED DIGGING

ITS NEST.

SHE USES IT TO LAY AROUND
100 EGGS THAT LOOK LIKE

GLOSSY GOLF BALLS.

[MUSIC CONTINUES]

DYLAN: THEIR SOFT SHELLS CAN
EASILY ABSORB ANY IMPACT AT

THE BOTTOM OF THE NEST.

ONCE HER EGGS ARE LAID, SHE
SEALS THE NEST.

THE SAND HAS A VITAL ROLE TO
PLAY.

ITS TEMPERATURE OVER THE
NEXT 8 WEEKS WILL NOT ONLY

HAVE AN INFLUENCE ON THE
INCUBATION PERIOD, BUT WILL

ALSO BE A DETERMINING FACTOR
IN THE GENDER OF THE HATCHLINGS.

UP TO 80 DEGREES FAHRENHEIT,
THEY WILL BE MALE.

ANY WARMER THAN THAT, AND
THE YOUNG WILL BE MOSTLY FEMALE.

AFTER SPENDING 40 MINUTES
SWEEPING THE SAND TO HIDE

ANY TRACE OF HER NEST, THE
FEMALE LEAVES HER EGGS TO

THEIR FATE AND RETURNS TO
THE OCEAN.

WHILE THIS MIGHT SEEM LIKE A
HIGH-RISK STRATEGY, THE

EVIDENCE IS THAT IT WORKS.

MARINE TURTLES COME FROM A
LONG LINEAGE WHICH GOES BACK

200 MILLION YEARS.

NOW THAT'S SOME IMPRESSIVE
FAMILY HISTORY.

UNDER THESE TROPICAL SKIES
THERE'S A NATURAL

ENVIRONMENT WHICH IS NEITHER
FULLY LAND NOR SEA.

IT'S A VAST AREA OF FOREST
GROWING OUT OF THE WATER

ITSELF.

THESE ARE CALLED MANGROVE
FORESTS AND THEY PLAY A

PRIMORDIAL ROLE HERE IN THIS
CARIBBEAN ENVIRONMENT.

THEY'RE SPAWNING AREAS FOR
MARINE SPECIES AND ACT AS

WATER FILTERS, FORMING
BUFFER ZONES WHICH PROTECT

THE SHORES FROM HURRICANES.

AT LOW TIDE, THE MIGHTY
GROUND BELONGS TO THE CRABS.

ESPECIALLY FIDDLER CRABS
WHOSE MALES ARE RECOGNIZABLE

BY THEIR SINGLE, OVERSIZED,
HYPER-DEVELOPED CLAW.

THE SMALL PINCER IS USEFUL
FOR RUMMAGING IN THE SILT.

ITS SIZE IS ADAPTED TO ITS
SMALL MOUTH PARTS.

BUT WHAT IS THE BIGGER ONE
FOR?

EACH MALE IS LORD OF ITS OWN
TERRITORY, A BURROW THAT HE

BUILDS, MAINTAINS AND
DEFENDS FIERCELY.

THE LARGE CLAW IS IN FACT A
WEAPON, BUT IT IS MAINLY A

DETERRENT AS VIOLENT
CONFRONTATION IS RARE.

[MUSIC]

DYLAN: BUT ITS MAIN ROLE IS
AS PART OF ITS DISPLAY; A

SHOW DURING WHICH EACH MALE
PERFORMS A SERIES OF

MOVEMENTS USING THIS
REMARKABLE APPENDAGE.

THE AIM IS TO ATTRACT THE
SMALL-PINCERED FEMALES TO

LAY THEIR EGGS IN HIS NEST.

AND WHO COULD RESIST SUCH
GRACEFUL CHOREOGRAPHY?

[MUSIC CONTINUES]

DYLAN: IN THIS NEW WORLD
CRUSTACEAN ORCHESTRA, EACH

SPECIES OF FIDDLER HAS ITS
OWN RHYTHM, FREQUENCY AND

SEQUENCE OF MOVES.

IN THE HEART OF THE MANGROVE
FOREST, THESE LITTLE CRABS

HAVE DEVELOPED A SIMPLE YET
EFFECTIVE METHOD OF

COMMUNICATION BY WAY OF BODY
LANGUAGE.

IT MAKES EACH OF THEM FLUENT
IN THE LANGUAGE OF LOVE.

AFTER THE BREAK, WHO NEEDS
TO SWIM WHEN YOU CAN WALK ON

WATER?

THESE DURABLE DECAPODS MAKE
THEIR HOME BETWEEN A ROCK

AND A HARD PLACE.

LATER, WE'LL MEET A STRIKING
SHRIMP THAT CAN'T HELP BUT

CATCH THE EYE, WHEN "EARTH
ODYSSEY" RETURNS.

.

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

[MUSIC]

DYLAN: THE ANIMAL KINGDOM
DOESN'T DISCRIMINATE WHEN IT

COMES TO CREATURES WHO LOVE
THE WATER.

THEY COME IN ALL SHAPES,
SIZES AND SPECIES.

AND WHILE MANY MAY NOT SPEND
THEIR LIVES UNDER THE WAVES,

FOR EVERY CREATURE, SURVIVAL
IS DIRECTLY TIED TO THEIR

NEED FOR WATER.

BUT THERE'S ALWAYS TIME FOR
A BREAK ALONG THE RIVERBANKS.

[MUSIC]

DYLAN: THE WATERFRONT IS ITS
OWN BEVY OF ACTIVITY THAT

SEES ANIMALS OF EVERY KIND
TAKING PART.

THIS LORD OF THE LILLIES
APPEARS TO WALK ON WATER AS

IT SEARCHES FOR A SNACK.

THE JACANA MOVES EASILY
ACROSS THE FLOATING

VEGETATION THANKS TO ITS
UNIQUE PHYSICAL ATTRIBUTES.

THEIR FEET HAVE LONG,
OVER-DEVELOPED TOES THAT

ALLOW THEM TO SPREAD THEIR
WEIGHT EVENLY AND EFFECTIVELY.

SO EFFECTIVELY, IN FACT, THE
WATER LILLIES HARDLY DIP AS

THEY STAND ON THEM.

THIS IMPRESSIVE FEAT COMES
WITH A DELICIOUS REWARD-

FOOD.

THERE'S ALWAYS AMPLE
PICKINGS OF INSECTS AND

INVERTEBRATES OUT ON THE
WATER WHERE OTHERS AREN'T

ABLE TO REACH.

IT'S A PRIVATE DINING AREA
ALL TO THEMSELVES.

THOUGH JEALOUS EYES ARE
NEVER FAR AWAY.

EACH FISHING BIRD HAS THEIR
OWN TECHNIQUE FOR FINDING

A MEAL.

SOME DIVE.

WHILE OTHERS SPEAR.

BUT FOR ALL, IT'S THE SIZE
OF THE CATCH AND SIZE OF THE

BIRD THAT MAKES THE
DIFFERENCE.

AND WHEN IT COMES TO SIZE,
TWO FISHING BIRDS IN THE

SAVANNA STAND TALL AS THE
GOLD STANDARD.

THE FIRST, THE GOLIATH
HERON, THE BIGGEST HERON

IN THE WORLD.

[MUSIC]

DYLAN: IT STANDS 5 FEET
TALL.

[MUSIC CONTINUES]

DYLAN: ITS COMPETITOR, A
SOARING RAPTOR, THE FISH EAGLE.

[MUSIC CONTINUES]

DYLAN: WITH A WINGSPAN
REACHING ALMOST 8 FEET, IT

JOINS THE GOLIATH HERON AS
ONE OF EARTH'S MOST

IMPRESSIVE FISHERMEN.

COMING UP, THESE COLORFUL
CRUSTACEANS LOOK ABSOLUTELY

CRABULOUS.

AND LATER, WE'LL MEET A
DEEPSEA SWIMMER WITH A

SEE-THROUGH STYLE.

ALL THIS AND MORE NEXT ON
"EARTH ODYSSEY."

.

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

[MUSIC]

DYLAN: BIZARRE SHAPES,
VIBRANT COLORS, SKELETONS

ON THE OUTSIDE.

CRUSTACEANS ARE A CLASS OF
ANIMAL THAT SEEMS STRAIGHT

OUT OF THE IMAGINATION.

BUT THESE CREATURES ARE MORE
THAN JUST AN INTRIGUING

SIGHT, THEY ARE CONSUMMATE
SURVIVORS.

OVER MILLIONS OF YEARS EACH
SPECIES HAS ADAPTED TO HAVE

HIGHLY-SPECIALIZED SKILLS THAT
ARE AS UNIQUE AS THEIR LOOK.

ABLE TO THRIVE FROM THE
DEEPEST OCEAN TRENCHES TO

THE SUN-SOAKED SHORES.

CRUSTACEANS CAN BE FOUND
EVERYWHERE.

CRABS, FOR INSTANCE, MEET ON
ROCKS BETWEEN THE LAND AND

THE SEA.

[MUSIC]

DYLAN: BUT THEY ONLY EMERGE
BRIEFLY FROM THEIR FAVORITE

PLACE.

[MUSIC CONTINUES]

DYLAN: SEVERAL MILLION YEARS
OLD, THIS GROUP IS A BRANCH

OF THE KINGDOM ANIMALIA
WHICH CONTAINS ABOUT 50,000

SPECIES; MOST OF WHICH ARE
AQUATIC.

IT ISN'T ALWAYS EASY TO
OBSERVE THEM IN THEIR

NATURAL ENVIRONMENT BECAUSE
THEY HIDE IN HOLES AND

CRACKS DURING THE DAY.

[MUSIC CONTINUES]

DYLAN: THESE ANCIENT ANIMALS
LIVE IN EVERY REGION OF THE

WORLD.

FROM THE SEA SURFACE TO
DEPTHS OF THOUSANDS OF FEET.

THEY VARY IN SIZE FROM WELL
UNDER AN INCH TO MORE THAN

10 FEET FOR THE JAPANESE
SPIDER CRAB; THE LARGEST

KNOWN CRUSTACEAN IN THE
WORLD.

THEIR CLASSIFICATION IS VERY
COMPLEX.

[MUSIC]

DYLAN: THERE ARE
BRACHIOPODS; SO NAMED

BECAUSE THEY HAVE GILLS ON
THEIR FEET, SUCH AS ARTEMIA

WHICH BREATHE BY TAKING IN
OXYGEN FROM THE WATER

THROUGH THEIR FEET.

OR CIRRIPEDES SUCH AS
BARNACLES, WHOSE DISTINCTIVE

FEATURE IS THAT THEY SPEND
THEIR ENTIRE LIFE ATTACHED

TO THE SAME PLACE.

THERE ARE MANY SUBCLASSES
TOO.

THE ONE WE ARE INTERESTED IN
IS MALACOSTRACA AS IT

CONTAINS THE ORDER DECAPODA
WHICH INCLUDES THE WORLD'S

BEST-KNOWN CRUSTACEANS.

[MUSIC CONTINUES]

DYLAN: DECAPODS, SO NAMED
BECAUSE OF THEIR 10 LEGS,

INCLUDE CRUSTACEANS SUCH AS
SHRIMPS, CRAYFISH, CRABS AND

SLIPPER LOBSTERS.

AND WITHIN THIS GROUP THERE
ARE SWIMMING CRUSTACEANS AND

WALKING CRUSTACEANS.

SOME, LIKE LOBSTERS, SLIPPER
LOBSTERS AND CRAYFISH HAVE A

VERY LONG, WELL-DEVELOPED
ABDOMEN ENDING IN A TAIL FIN.

[MUSIC CONTINUES]

DYLAN: WHILE OTHERS SUCH AS
HERMIT CRABS HAVE ASYMMETRICAL

ABDOMENS.

AND LASTLY, THERE ARE THOSE
THAT ARE ROUNDER WITH A

SMALL ABDOMEN OFTEN FOLDED UNDER
THE THORAX LIKE SPIDER CRABS.

[MUSIC CONTINUES]

DYLAN: BUT THIS GROUP IS NOT
AS SIMPLE AS IT SEEMS.

THERE ARE MANY OTHER
SUBCLASSES SUCH AS AMPHIPODS

REPRESENTED BY THESE
SKELETON SHRIMPS.

OR ISOPODS, REPRESENTED BY
PARASITES.

CRUSTACEANS COME IN ALL
SORTS OF SHAPES AND COLORS

AND VARY FROM ONE EXTREME TO
ANOTHER.

SOMETIMES THEY LOOK ALMOST
UNREAL.

WHILE ALL THESE CREATURES
BELONG TO THE SAME GROUP,

THEY CAN BE WILDLY
DIFFERENT; SOME LIVING IN

THE SEA, OTHERS IN FRESH
WATER LIKE HERE.

CRAYFISH EVOLVED FROM
PRIMITIVE MARINE ANCESTORS

LIKE ALL ITS RIVER AND
LAKE-DWELLING FELLOWS.

MAKING AN APPEARANCE IN
ALMOST EVERY BODY OF WATER

ON EARTH, CRUSTACEANS ARE
EVERYWHERE.

WHEN WE RETURN, WE'RE DIVING
INTO THE DEEP OCEAN FOR A

LOOK AT SOME DELICATE
DECAPODS.

UP NEXT ON "EARTH ODYSSEY."

.

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

[MUSIC]

DYLAN: EARTH'S OCEAN
ENVIRONMENTS ARE CONSTANTLY

MOVING AND SHIFTING WITH THE
CURRENT.

BUT EVEN IN THE WATER, SOME
CREATURES EXCEL AT STAYING PUT.

BARNACLES, FOR INSTANCE,
GATHER PARTICLES OF PLANKTON

BY CONSTANTLY FILTERING THE
WATER.

THESE SMALL, BARELY VISIBLE
CRUSTACEANS OFTEN FIND

THEMSELVES INVADED BY CORAL
AND THEIR HARD PART IS

NO LONGER VISIBLE.

HERE, LESS COLONIZED, IT'S
EASIER TO SEE THEM FEEDING.

[MUSIC]

DYLAN: BARNACLES CAN LIVE
NEAR THE SURFACE BETWEEN THE

AIR AND WATER.

WHAT YOU MIGHT THINK AT
FIRST GLANCE ARE SHARP BUMPS

ON THE ROCKS ARE ACTUALLY
LIVING CREATURES.

THESE ANIMALS HAVE CALCIUM
PLATES WHICH CAN BE PULLED

TOGETHER.

THIS HERMETIC SEAL PREVENTS
THE BARNACLES FROM DRYING

OUT AND IT MEANS THEY CAN
WITHSTAND LONG PERIODS OUT

OF THE WATER.

THEY ALSO NEED SOMETHING ON
WHICH TO ATTACH THEMSELVES;

EVEN SOMETHING LIVING.

[MUSIC CONTINUES]

DYLAN: ALWAYS IN PAIRS,
HARLEQUIN SHRIMPS FEED

EXCLUSIVELY ON STARFISH.

WITH THEIR PINCERS, THEY
HAVE CUT OFF AN ARM AND ARE

TAKING IT AWAY TO EAT.

[MUSIC CONTINUES]

DYLAN: LESS THAN A HALF INCH
IN LENGTH, SKELETON SHRIMP

ARE THE ONLY CRUSTACEANS
ABLE TO STAND UP BY

ANCHORING THEMSELVES WITH
THEIR REAR LEGS.

THEY CAPTURE THEIR PREY WITH
THEIR MUCOUS-SECRETING

ANTENNAE; A THICK AND VISCUS
SUBSTANCE.

THIS MUCOUS PARALYZES THE
PLANKTON LARVAE AND SMALL

INVERTEBRATES THEY FEED ON.

BUT TO FEED, SOME SHRIMP HAVE
ADOPTED A DIFFERENT TECHNIQUE.

THEY OFFER THEIR SERVICES
IN WHAT ARE KNOWN AS CLEANING

STATIONS.

[MUSIC CONTINUES]

DYLAN: THEY REMOVE OTHER
CREATURES' PARASITES.

[MUSIC CONTINUES]

DYLAN: AND THOSE WHO MIGHT'VE
BECOME PREDATORS IF IT WASN'T

FOR THIS INDISPENSABLE REMOVAL
FUNCTION, OPEN THEIR EARS

AND MOUTHS WIDE WHERE THE
CLEANER SHRIMP WORK UNDISTURBED.

[MUSIC CONTINUES]

DYLAN: IT'S A REMARKABLE
EXAMPLE OF SOLIDARITY AND

TRUST; SHOWING HOW ANIMALS
CAN HELP EACH OTHER THRIVE

IN EARTH'S WILDEST WATERS.

WITH SO MUCH OF OUR PLANET
COVERED BY WATER IT'S NO

SURPRISE THAT THERE ARE SO
MANY CAPTIVATING SIGHTS IN

THE AQUATIC ANIMAL KINGDOM.

FROM MOUNTAIN STREAMS TO
OPEN OCEAN, OUR WATERWAYS

ARE BURSTING WITH AN
INCREDIBLY DIVERSE ARRAY OF

LIFE MADE ALL THE MORE
ASTONISHING BY THE DIFFERENT

WAYS THEY'VE LEARNED TO
SURVIVE BENEATH THE SURFACE.

WE'RE SO GLAD YOU COULD JOIN
US AND HOPE TO SEE YOU FOR

THE NEXT EPISODE OF "EARTH
ODYSSEY."
