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 AND IT'S TIME FOR A WILD

JOURNEY ON EARTH ODYSSEY.

TODAY, WE'RE ON THE HUNT TO SEE
WHAT IT TAKES TO BE ONE OF

EARTH'S MOST PROLIFIC PREDATORS.

YOU HAVE TO BE QUICK IF YOU'RE
GOING TO KEEP UP WITH THESE

FIERCE FELINES.

AND WE'LL SEE WHY FEEDING THIS
CANINE CREW IS A FULL-TIME JOB.

LATER, ONE OF AFRICA'S FISHING
EXPERTS IS OUT TO STRUT ITS

STUFF.

BUT WE BEGIN OUR JOURNEY AT THE
WATER'S EDGE TO MEET AN APEX

PREDATOR WITH A PREHISTORIC
STYLE.

THERE'S THIS AND SO MUCH MORE
HERE ON EARTH ODYSSEY.

[MUSIC]

DYLAN: SURVIVAL IN THE WILD
REQUIRES GREAT SKILL,

ADAPTABILITY AND RESILIENCE.

IN RARE CASES, ANIMALS DEVELOP
EXCEEDINGLY STRANGE TRAITS AND

ODD PHYSICAL CHARACTERISTICS TO
MAKE THEM MORE PERFECTLY SUITED

TO THEIR ENVIRONMENT.

WHILE THESE STRANGE LOOKS MAY BE
EYE-CATCHING, EQUALLY AS

INTERESTING ARE THEIR STRANGE
BEHAVIORS.

JUST LOOK ALONG THE WATER'S EDGE
IN AFRICA, WHERE CROCODILES HAVE

PERFECTED A LOG-ROLLING
TECHNIQUE CRUCIAL TO THEIR

SUCCESS.

ON THE SHORES OF THIS AFRICAN
WATERING HOLE, A CROCODILE

PATIENTLY SITS AND OBSERVES THE
WILDLIFE.

ABSOLUTELY MOTIONLESS,
HE IS TOTALLY INSCRUTABLE.

THIS SPOONBILL ISN'T IN
MUCH DANGER.

THESE LARGE REPTILES RARELY
ATTACK BIRDS.

HOWEVER, THIS ONE SEEMS
TO BE TAKING AN INTEREST IN THE

LARGER ANIMALS DRINKING AT THE
WATER'S EDGE.

BUT THERE'S NOTHING TO
WORRY ABOUT.

THE CROC CHANGES COURSE AND
TRIES TO CATCH A FISH.

TO NO AVAIL.

LUCKILY, HE FEELS SOME
VIBRATIONS IN THE WATER AND

HEADS OVER TO SEE WHAT'S CAUSING
THEM.

CROCODILES, LIKE THESE TWO HERE,
HAVE NO INCISOR TEETH OR MOLARS,

SO THEY DON'T CHEW THEIR FOOD.

THEY HAVE TO RELY ON A RATHER
SPECIALIZED TECHNIQUE.

THEY ROLL OVER AND OVER
WITH THEIR PREY FIRMLY GRIPPED

IN THEIR JAWS.

BUT CROCODILES DON'T JUST EAT
LARGE PREY.

WHEN THE WATER IS WELL-STOCKED,
FISH ARE THE MAIN PART OF THEIR

DIET.

NORMALLY, THESE GREAT
REPTILES HAVE A CLEAR PREFERENCE

FOR GENTLY SLOPING RIVERBANKS.

IT'S THE PERFECT TERRAIN
FOR RESTING THEIR HEAVY BELLIES

AND SHORT LEGS.

THEY LIKE FLAT BANKS AND
SANDY SPITS WHERE THEY CAN LULL

UP AND BASK IN THE SUN.

AND BEST OF ALL IS TO
KEEP PART OF THEIR BODY IN THE

WATER SO THEY CAN SLIP EASILY
BACK INTO THE RIVER.

BUT THIS ENORMOUS
16-FOOT-LONG CROC HAS DONE JUST

THE OPPOSITE.

WHO KNOWS WHY, BUT HE HAS
SETTLED DOWN HIGHER UP ON A

ROCKY PART OF THE SHORE.

IT'LL TAKE A LOT OF
EFFORT TO GET HIS ENORMOUS BODY

BACK DOWN TO THE RAPIDS.

IN THE SWIRLING CURRENT,
IT'S CLEAR THE CROC IS NOT AT

HOME IN TURBULENT WATER.

BUT WITH A LAST PUSH, HE'LL MAKE
IT.

COMING UP, WHEN IT COMES
TO HUNTING SKILLS, THESE CAT

CUBS ARE FAST LEARNERS.

AND SIBLING RIVALRY IS A
SURVIVAL SKILL IN THIS FURRY

FAMILY.

PLUS, WHO NEEDS CLAWS OR FANGS
WITH A BEAK AS SHARP AS THEIR

SKILLS WHEN EARTH ODYSSEY
RETURNS.

.

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

DYLAN: HUNTING A PREDATOR
DOESN'T MEAN LIFE COMES WITHOUT

DANGER.

YOUNG CHEETAHS CAN BE A TARGET
FOR LARGE PREDATORS, SO THE

YOUNG USUALLY STICK CLOSE TO
MOM.

SO WHEN SHE'S NOT AROUND, THERE
HAS TO BE A GOOD REASON, AND THE

CUBS KNOW IT.

CATS CAN'T HELP THEIR CURIOSITY.

ONE AFTER THE OTHER, THEY
INSTINCTIVELY FOLLOW IN THE

DIRECTION TAKEN BY THEIR MOTHER.

BUT THE BUSH IS DENSE AND
VISIBILITY VERY RESTRICTED.

WITH NO CLUES AS TO WHICH
DIRECTION TO TAKE, THE CHEETAH

CUBS CLING TOGETHER AND ARE
RELUCTANT TO RISK GOING ANY

FARTHER.

THE WIND IS IN THE RIGHT
DIRECTION, BUT THE SCENTS IT'S

CARRYING ARE TOO PROFUSE AND
MIXED.

FINALLY, IT'S THE ALARM
CRY OF THE IMPALA THAT TELLS

THEM WHERE THEIR MOTHER IS.

THE SUDDEN ARRIVAL OF ALL THE
CUBS OBLIGES HER TO THROW

HERSELF INTO THE HUNT TOO SOON.

IN THE PANIC FOLLOWING
THE ATTACK, THE YOUNG CHEETAHS

ONCE AGAIN FIND THEMSELVES LEFT
TO THEIR OWN DEVICES.

THEY'RE ALL THE MORE KEEN ON
FINDING THEIR MOTHER BECAUSE

SHE'LL HAVE SOMETHING FOR THEM
TO EAT.

THEY'RE IN A MORE OPEN AREA
HERE, AND THE YOUNG CATS CAN NOW

RELY MORE ON THEIR EYESIGHT.

BUT STILL, NOT SEEING THEIR
MOTHER, THEY CALL OUT.

EACH CHEETAH CUB USES
ALL ITS SENSES AND BRINGS ABOUT

A RAPID RESULT.

THERE ARE TWO PIECES OF GOOD
NEWS.

THEIR MOTHER IS NEARBY, AND HER
HUNT WAS SUCCESSFUL.

WHEN THEY'VE CAPTURED THEIR
PREY, CHEETAHS ARE UNDER

CONSTANT THREAT FROM STRONGER
ANIMALS.

HYENAS, A LEOPARD, OR LIONS.

SO WHEN THEY FEED, THERE'S
ALWAYS A SENTRY.

THE CHEETAH RELIES
ESSENTIALLY ON ITS EYESIGHT.

AS WITH ALL FELINES, THEY HAVE
BIG EYES PLACED ON THE FRONT OF

THE HEAD, WHICH GIVES THEM THE
EXCELLENT BINOCULAR VISION

THAT'S NECESSARY FOR JUDGING
DISTANCES.

THEIR FIELD OF VISION IS
INCOMPARABLE.

280 DEGREES.

THAT'S 100 DEGREES MORE THAN
MAN'S.

BUT THEIR VISUAL ACUITY IN
DAYLIGHT IS NO BETTER THAN OURS.

IT'S AT NIGHT THAT THERE'S A
DIFFERENCE.

THEIR VISION IS THEN SIX
TO EIGHT TIMES SUPERIOR TO THAT

OF HUMANS.

THE BIG CATS SEE SO WELL AT
NIGHT BECAUSE THEIR VISUAL

SYSTEM ALLOWS THEM TO CAPTURE
THE SLIGHTEST LIGHT.

FOR THEM, A NIGHT LIT BY
THE FULL MOON IS ALMOST THE SAME

AS BROAD DAYLIGHT TO US.

THE HUMAN EYE IS MADE UP
OF RODS, OR LIGHT-SENSITIVE

CELLS, AND CONES THAT
RECONSTITUTE COLORS.

BUT A FELINE'S RETINA CONSISTS
ALMOST ONLY OF RODS.

CONSEQUENTLY, THE LEOPARD AND
THE LION DON'T SEE COLORS, BUT

THEY DO SEE IN THE DARK.

THEY ALSO HAVE, AT THE BACK OF
THE EYE, A REFLECTIVE LAYER

CALLED THE CHOROIDAL TAPETUM,
WHICH HELPS TO INCREASE THE

AMOUNT OF LIGHT REACHING THE
RETINA.

AND THAT MEANS ONE THING.

NIGHT VISION.

WELL, NOT EXACTLY, BUT THEY ARE
ABLE TO USE THE SLIGHTEST AMOUNT

OF LIGHT TO THEIR BENEFIT.

AND IN THE WILD, EVERY ADVANTAGE
CAN MAKE ALL THE DIFFERENCE IN

SURVIVAL.

WHEN WE COME BACK, A
CANINE FAMILY THAT PLAYS

TOGETHER, STAYS TOGETHER IN THE
AFRICAN SAVANNAH.

AND SEE HOW THIS BRAZEN BIRD
KEEPS ITS BELLY FULL, NEXT ON

EARTH ODYSSEY.

.

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

DYLAN: IN THE WILD, SPOTTING A
PREDATOR ISN'T TOO HARD TO DO.

SHARP TEETH, STRONG JAWS, AND
NOT EXACTLY THE FRIENDLIEST

ATTITUDE TOWARDS THEIR PREY
ANIMAL NEIGHBORS.

BUT WHAT REALLY DEFINES A
PREDATOR IS OPPORTUNITY.

RARELY IS A MEAL EASY TO FIND OR
CATCH, SO EARTH'S HUNTERS HAVE

TO USE THEIR CUNNING AND
STRATEGIC ACTION TO CREATE THAT

ONE OPPORTUNITY THAT CAN MEAN
THE DIFFERENCE BETWEEN FILLING

THEIR BELLIES OR GOING HOME
HUNGRY.

FOR OUR PLANET'S
PREDATORS, HUNTING CAN SEEM LIKE

A FULL-TIME JOB.

IT'S DIFFICULT ENOUGH CATCHING
PREY FOR THEMSELVES, BUT THE

IMPORTANCE OF THEIR SUCCESS
SKYROCKETS WHEN THERE ARE MORE

MOUTHS TO FEED.

THESE YOUNG JACKALS ARE
EAGERLY AWAITING THEIR PARENTS'

RETURN BECAUSE IT MEANS FOOD.

MOM IS THE FIRST TO ARRIVE, AND
HER LITTER OF PUPS WASTES NO

TIME IN SEEING WHAT'S ON THE
MENU.

WITH THEIR BELLIES FULL
AND ENERGY UP, THESE ROWDY

ADOLESCENTS CAN GET BACK TO ONE
OF THEIR FAVORITE ACTIVITIES,

PLAY.

GAMES OF CHASE, WRESTLING, AND A
CHEEKY CHOMP OR TWO IS ALL PART

OF THEIR TRAINING FOR WHEN THEY
HAVE TO FEND FOR THEMSELVES.

LUCKILY, AS ADULTS, THEY WON'T
BE COMPLETELY ALONE.

JACKALS HUNT IN PAIRS OR SMALL
GROUPS, SO BONDING WITH

LITTERMATES CAN BE CRUCIAL TO
THEIR FUTURE SUCCESS.

AFTER THEIR THOROUGH
TRAINING SESSION, A LITTLE REST

IS IN ORDER.

THEY ARE HAPPY TO RELAX WHILE
SOME NOSY NEIGHBORS MAKE THEIR

WAY PAST.

ELEPHANTS ARE A LITTLE
OUT OF THEIR LEAGUE WHEN IT

COMES TO PREY.

THIS IS DEFINITELY A SITUATION
WHERE THE JACKALS' EYES ARE FAR

BIGGER THAN THEIR STOMACHS.

ONE ANIMAL WITH NO LIMIT
TO THEIR APPETITE IS THE HYENA.

THIS MOTHER IS DESPERATE TO FIND
SOME PREY WITH HER HUNGRY CUBS

WAITING AT HOME.

THE HERD OF WILDEBEEST COULD BE
THE PERFECT OPPORTUNITY.

IT WON'T BE EASY, BUT SHE'S GOT
TO TRY.

HER HUNTING PROCESS IS SIMPLE,
BUT USUALLY EFFECTIVE.

PHASE ONE, DISRUPT AND DIVIDE
THE HERD.

PHASE TWO, ISOLATE A TARGET
AND STAY ON ITS TAIL.

PHASE THREE, CUT THEM OFF AND
TAKE THE PREY BY SURPRISE.

FINAL PHASE, KEEP UP THE
PACE AND RUN FASTER.

OR SLOW DOWN AND ADMIT DEFEAT.

ALL THE HYENA CAN DO NOW
IS SLINK AWAY, EXHAUSTED AND NOW

HUNGRIER THAN EVER.

HIDING AMONGST THE VEGETATION,
THESE DWARF MONGOOSES ARE ON

HIGH ALERT.

BUT IT'S NOT THE WARTHOG THAT
HAS THEM SPOOKED, IT'S THEIR

CARGO.

EVEN FOR SKILLED HUNTERS LIKE
THESE, WHEN THEIR BABIES ARE

TRAVELING ALONGSIDE THEM, EVERY
MOVE MUST BE MADE WITH CAUTION.

AT ONLY ABOUT 15 INCHES,
NOSE TO TAIL, WEIGHING IN AT

AROUND 12 OUNCES, THE DWARF
MONGOOSE IS A SURPRISING

ADDITION TO EARTH'S ELITE
HUNTERS.

THEIR YOUNG ARE THE
SPITTING IMAGE OF THEM, MERELY A

MINI VERSION.

AT JUST FOUR MONTHS OLD,
THIS LITTLE ONE WILL BE ABLE TO

HUNT FOR HIMSELF.

WHILE THEY MAY BE ONE OF
AFRICA'S SMALLEST CARNIVORES,

THEY'RE CERTAINLY BIG ON
LEARNING FAST.

AFTER THE BREAK, WE'LL MEET A
PREDATOR THAT'S PERFECTED

THE ART OF THIS STEALTH ATTACK.

THERE'S A LOT MORE EARTH ODYSSEY
COMING UP NEXT.

.

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

DYLAN: WHEN LOOKING AT THE
ESSENCE OF THE PREDATOR, WHAT

MAKES THEM SO DANGEROUS AND
IMPRESSIVE IS ONE TRAIT, ITS

CAPACITY TO CATCH PREY.

THERE IS HIGH COMPETITION IN THE
SAVANNA TO SEE WHICH PREDATOR

HOLDS THE BEST HUNTING RECORD.

BUT THERE IS A STANDOUT, AND
HERE HE IS, THE CHEETAH.

WHEN HE COMPETES, DEPENDING ON
THE CIRCUMSTANCES AND THE PLACE,

HE WINS THREE TO SEVEN TIMES OUT
OF TEN.

THE LION WINS ONE TIME
OUT OF THREE, AND IT'S ONLY ONE

IN 20 FOR THE LEOPARD.

NO TERRESTRIAL ANIMAL CAN OUTRUN
THE CHEETAH, BUT HE IS UNABLE TO

SUSTAIN HIS EFFORT FOR LONG.

RUNNING, WHERE LIFE OR DEATH IS
OFTEN AT STAKE, IS ALSO A

QUESTION OF ENDURANCE.

THE HYENA STANDS OUT IN TESTS OF
STAMINA.

IT CAN RUN NEARLY 30 MILES PER
HOUR FOR LONG DISTANCES.

THE HERBIVORES ARE WELL
REPRESENTED BY THE WILDEBEEST.

IT'S NOT AS FAST AS A GAZELLE,
LIKE THE IMPALA, THAT CAN RUN AT

MORE THAN 50 MILES PER HOUR, BUT
IT HAS GREATER ENDURANCE.

THE ONE WHO FALLS IS THE
WEAKEST, OR THE ONE WHO GOT OFF

TO A BAD START.

THE STARTING LINE FOR THESE
HIGH-RISK COMPETITIONS IS OFTEN

AT THE WATER'S EDGE.

IT'S A VERY DANGEROUS SPOT FOR
PREY.

THE LIONS MAY TEST THEIR
SKILLS HERE WITHOUT EVEN KNOWING

WHETHER IT'S A SIMPLE TRAINING
SESSION OR REAL COMPETITION.

INCREDIBLE REFLEXES ARE
VITALLY IMPORTANT FOR PREY,

BUT IT'S EQUALLY IMPORTANT FOR
THE HUNTERS.

BIRDS ARE THE MOST REMARKABLE IN
THIS DOMAIN.

THIS STRIATED HERON APPROACHES
ITS PREY WITHOUT EVER TAKING ITS

EYES OFF IT.

TO GIVE ENOUGH SURPRISE TO WORK,
THE BIRD'S BEAK MUST MOVE FASTER

THAN THE FISH CAN REACT.

HERONS ARE IMPRESSIVE
CHAMPIONS OF PATIENCE AND

STILLNESS.

THE GREY HERON CAN STAY
COMPLETELY STILL FOR MANY

MINUTES, WAITING FOR ITS PREY TO
COME INTO ITS FIELD OF ATTACK.

THOUGH IT LOOKS LIKE
TODAY, LUCK WASN'T ON THE

HERON'S SIDE.

EARTH'S PREDATORS ARE AN
IMPRESSIVE REMINDER OF WHAT IT

TAKES TO SURVIVE IN THE WILD.

THEY MUST DEVELOP THE STRENGTH
AND SKILLS TO CATCH THEIR PREY

IN COMPETITIVE ENVIRONMENTS,
ADAPT TO CHANGING CLIMATES AND

RESOURCES, AND WORK HARD EVERY
DAY TO ENSURE THE SAFETY AND

SUCCESS OF THE NEXT GENERATION.

THANK YOU FOR COMING ALONG ON
TODAY'S JOURNEY.

WE HOPE YOU'LL JOIN US FOR THE
NEXT ONE, RIGHT HERE ON EARTH

ODYSSEY.
