THIS BEAUTIFUL BARN OWL IS ON THE HUNT FOR A MEAL,

AND SOMEWHERE IN THIS FIELD, BENEATH ALL THIS SNOW,

IS A SINGLE MOUSE.

OUT OF SIGHT, IT MUST BE SAFE.

THE OWL CAN'T SEE IT,

BUT THE BIRD IS NOT GIVING UP ON BREAKFAST JUST YET.

♪♪

BULL'S-EYE, NO MORE MR. MICE GUY.

SOMEHOW, THIS OWL IS DEADLY ACCURATE

EVEN WHEN THE MOUSE IS HIDDEN.

SO HOW DO OWLS CATCH PREY THEY CAN'T SEE?

♪♪

THERE ARE 225 SPECIES OF OWL

ACROSS EVERY CONTINENT EXCEPT ANTARCTICA.

FOUR-YEAR-OLD LILY IS A BARN OWL.

LILY, THAT'S A GOOD GIRL.

LILY IS ALSO A HIGH-FLYING MODEL AND ASPIRING ACTRESS.

HER AGENT, HANDLER,

LLOYD BUCK, IS THE U.K.'s TOP PREDATOR TRAINER.

Buck: WE DO FILMING WORK AND PHOTOGRAPHY WORK WITH LILY,

TRYING TO REPLICATE THAT NATURAL BEHAVIOR FOR THE CAMERA.

BARN OWLS LIKE LILY EAT SMALL RODENTS

THAT YOU FIND IN A LONG GRASS.

THEY'RE KNOWN TO HAVE VERY GOOD EYESIGHT,

BUT THEY'VE ALSO DEVELOPED OTHER SUPER SENSES.

Narrator: AND IT'S ONE OF THESE SUPER SENSES

THAT'S THE SECRET TO FINDING HIDDEN PREY.

OWLS LIKE LILY HAVE INCREDIBLE HEARING.

LILY'S WHOLE HEAD IS SHAPED LIKE A BIG FEATHERY SATELLITE DISH,

AND LIKE A SATELLITE DISH,

LILY'S FACE PICKS UP DISTANT SOUNDS AND AMPLIFIES THEM.

SHE CAN HEAR A MOUSE SQUEAK HALF A MILE AWAY.

[ MOUSE SQUEAKING ]

I WONDER IF SHE CAN PICK UP RERUNS OF "DOWNTON ABBEY."

IT'S A TERRIFIC SHOW.

ANYWAY, SPECIAL FEATHERS MUCH STIFFER

THAN FLIGHT FEATHERS LINE THE EDGE OF THE FACE AND FUNNEL

THOSE SOUNDS TOWARDS HER HIGHLY SENSITIVE EARS

HIDDEN BENEATH THOSE FEATHERS.

BUT IT'S ONE THING HEARING SOMETHING FAR AWAY.

FINDING IT IS ANOTHER.

SO LLOYD HAS SET UP A TEST TO SHOW

HOW SHE CAN CATCH PREY WITHOUT SEEING IT.

THIS LITTLE DEVICE EMITS A BEEP,

WHICH IF I PRESS THE CONTROLLER, YOU CAN HEAR IT.

Narrator: LLOYD HAS COME UP WITH AN OWL VERSION OF HIDE-AND-SEEK.

AS THE RULES SAY, LILY MUST FIRST COVER HER EYES.

THEN LLOYD HIDES THE DEVICE 100 YARDS AWAY.

Buck: PREY ANIMALS ARE NOT GOING TO MAKE IT EASY FOR LILY.

THEY STICK DOWN IN THE LONG GRASS,

SO THIS IS THE PERFECT AREA.

Narrator: WE'VE ENHANCED THE SOUND SO YOU CAN HEAR IT,

BUT IT'S ACTUALLY AS QUIET AS A MOUSE.

[ DEVICE BEEPING ]

YOU READY?

YEP.

[ LILY SHRIEKING ]

♪♪

[ DEVICE BEEPING ]

♪♪

IMAGINE YOURSELF IN LILY'S SHOES OR FEATHERS.

SUPPOSE YOU LOST YOUR CELL PHONE,

AND IT'S IN SOMEWHERE THE SIZE OF, SAY,

MADISON SQUARE GARDEN ON VIBRATE.

OH, ONE MORE THING. YOU'RE BLINDFOLDED.

HOW LONG DO YOU THINK IT WOULD TAKE TO FIND IT

IN AN AREA THAT BIG?

LILY PICKS UP THE FAINT SIGNAL IN LESS THAN 20 SECONDS,

AND AS SHE ZEROES IN,

HER BIRD-OF-PREY INSTINCTS TAKE OVER.

SHE CAN'T SEE THE ROBO-MOUSE, AND YET SHE'S DIRECTLY OVER IT.

NAILED IT.

NOT JUST CLOSE, A DIRECT HIT.

THAT'S A GOOD GIRL.

THIS CUTE LITTLE OWL IS IN FACT A SOUND-SEEKING MISSILE,

BUT HOW DID SHE FIND A TARGET SHE COULDN'T SEE?

AGAIN, IT'S ALL ABOUT LILY'S HEAD.

A BARN OWL'S RIGHT EAR IS HIGHER THAN ITS LEFT,

SO THE SQUEAK OF A MOUSE REACHES EACH EAR

AT FRACTIONALLY DIFFERENT TIMES.

THIS TINY DIFFERENCE MEANS

LILY CAN WORK OUT NOT ONLY THE EXACT DIRECTION

BUT THE DISTANCE OF THE SOUND.

HER OFFSET EARS CREATE A KIND OF SUPER ACCURATE

3-D SOUND-DETECTING MAP.

LILY'S HEARING IS AROUND 10 TIMES

MORE POWERFUL THAN OUR OWN.

INCREDIBLY, NO MATTER WHERE LLOYD HIDES IT, LILY LOCATES IT.

IT'S PINPOINT ACCURACY.

Narrator: LET THIS BE A WARNING.

DON'T HIDE FROM LILY.

SHE'LL FIND YOU EVERY SINGLE TIME.

THEY ARE AMAZING, AMAZING BIRDS.

[ INSECTS BUZZING ]

DEEP BENEATH THE WAVES, SOMETHING IS HIDING.

IT'S RIGHT IN FRONT OF YOU,

AN IT'S ONE OF NATURE'S MOST AMAZING CREATURES.

CAN YOU SEE IT?

TAKE A FEW SECONDS TO TRY AND FIND IT,

AND THREE, TWO, ONE, THERE IT IS.

LET'S SEE THAT AGAIN.

EVEN KNOWING IT'S THERE,

THIS OCTOPUS IS ALMOST IMPOSSIBLE TO SEE.

IT'S LIKE HARRY POTTER'S INVISIBILITY CLOAK IN REAL LIFE.

SO, HOW ARE OCTOPUSES SUCH MASTERS OF DISGUISE?

AROUND 300 SPECIES OF OCTOPUS LIVE IN EVERY OCEAN ON EARTH,

AND EVERY ONE HAS THE AMAZING ABILITY TO TRANSFORM.

THEIR DISGUISING SECRET IS IN THEIR INCREDIBLE SKIN.

IT'S MADE OF ELASTIC CELLS FILLED WITH COLORED PIGMENTS.

EACH CAN STRETCH AND SHRINK

TO CHANGE THEIR SIZE AND COLOR AT WILL.

IT LOOKS TRIPPY UP CLOSE, BUT IT'S LIKE MAGIC IN THE WILD.

THOUSANDS OF CELLS ALL COLOR MATCH

THEMSELVES TO THE SURROUNDINGS

A BIT LIKE HOW INDIVIDUAL PIXELS ON A TV

CREATE A PERFECT IMAGE ON A SCREEN.

BUT OCTOPUSES DON'T STOP AT SIMPLY CHANGING COLOR.

THEY ARE SHAPE-SHIFTERS.

THE SKIN CAN MOVE TO FORM BUMPS, RIDGES,

SPIKES AND HARD EDGES LIKE THE PLANT LIFE

AND ROCKS AROUND THEM AND RESULT:

NOW YOU SEE ME, AND NOW YOU DON'T.

TO EVADE PREDATORS,

MOST OCTOPUSES WILL PULL THIS DISAPPEARING TRICK,

BUT IN SHALLOW WATERS AROUND SOUTHERN ASIA,

THERE IS ONE THAT DOES MUCH MORE THAN THAT, MUCH MORE.

IT SCARES OFF PREDATORS

BY IMPERSONATING MORE DANGEROUS CREATURES.

THIS IS THE MIMIC OCTOPUS.

BELIEVED TO HAVE A REPERTOIRE OF AT LEAST 15 KNOWN ALIASES,

WHEN A HUNGRY GREY REEF SHARK SWIMS NEAR,

IT FLATTENS ITS BODY INTO THE SHAPE OF A TOXIC

BOTTOM-DWELLING FISH OR GROWS SPIKES

AND TURNS ORANGE AND WHITE TO LOOK LIKE A LETHAL LIONFISH.

AND THEY'RE SO INTELLIGENT THAT THEY KNOW

THE BEST ALIASES TO USE,

LIKE WHEN FACED WITH A DAMSELFISH.

THEY MAY LOOK CUTE, BUT THEY ATTACK OCTOPUSES,

SO THE OCTOPUS SCARES IT OFF

BY IMPERSONATING THE DAMSELFISH'S OWN PREDATOR,

A VENOMOUS SEA SNAKE.

THE OCTOPUS IS SO GOOD AT MIMICKING,

IT EVEN TRICKED US.

SCIENTISTS DIDN'T KNOW THEY EXISTED UNTIL 20 YEARS AGO,

EVEN THOUGH THEY'VE BEEN SWIMMING IN PLAIN SIGHT

FOR MILLENNIA.

THE MIMIC OCTOPUS IS THE UNDISPUTED CHAMPION

OF HIDE-AND-SEEK.

♪♪

COMING UP: EXTRAORDINARY HUNTERS,

TOILET-CLIMBING RATS AND UNFREEZABLE FEET.

♪♪

Narrator: ON THE PLAINS OF AFRICA, PREDATORS ARE EVERYWHERE,

BUT WHAT'S THE MOST EFFICIENT HUNTER?

SURPRISINGLY, IT'S NOT LIONS.

THEIR HUNTING SUCCESS RATE CAN BE AS LOW AS 17 PERCENT.

HOW ABOUT CHEETAHS WITH THEIR EXTREME SPEED?

NOT EVEN CLOSE.

THEY ONLY CATCH AROUND HALF OF THEIR PREY.

HUMANS: EVEN WITH GUNS, THEIR SUCCESS RATE CAN BE

AS LOW AS 20 PERCENT.

SURPRISINGLY THE TOP DOG IS THE WILD DOG.

[ WILD DOG BARKS ]

THEY MAY RESEMBLE MAN'S BEST FRIEND,

BUT FOR THEIR PREY, THEY'RE ITS WORST NIGHTMARE

WITH AN INCREDIBLE 80 PERCENT HUNT-TO-KILL CONVERSION RATE.

SO WHAT MAKES WILD DOGS AFRICA'S MOST SUCCESSFUL HUNTERS?

MAGNIFICENT YET MENACING,

WILD DOGS ARE ALSO KNOWN AS PAINTED DOGS

BECAUSE OF THEIR STRIKING COATS.

IN PACKS OF UP TO 20, THEY ROAM THE EAST AFRICAN SAVANNA

WITH EACH PACK RULING TERRITORIES THE SIZE OF CHICAGO.

THESE NOMADIC DOGS CAN COVER 30 MILES EACH DAY,

HUNTING PREY FROM SMALL RABBITS TO HUGE WILDEBEEST.

THIS PACK OF 10 LIVES

IN THE N/A'AN KU SE RESERVE IN NAMIBIA,

AND FOR THE LAST 5 YEARS,

COLETTE MASSIER HAS BEEN LEARNING

HOW THESE KILLER CANINES CAN CATCH

ALMOST EVERYTHING THEY SET THEIR TEETH ON.

Massier: THEY'RE NOT THE BIGGEST.

I MEAN, THE LION AND LEOPARD IS FAR BULKIER,

MUCH STRONGER, WEIGHS A LOT MORE.

THESE GUYS ARE SLENDER. THEY'VE GOT SKINNY LITTLE LEGS

THAT YOU THINK COULD SNAP LIKE A TWIG,

BUT THEY ARE EXTREMELY SUCCESSFUL IN THEIR HUNTING.

Narrator: TO REVEAL WHAT MAKES THEM SO SUCCESSFUL,

COLETTE IS GOING INTO THE WILD DOGS' DOMAIN

TO EXAMINE THEIR HUNTING UP CLOSE.

SHE'S BRINGING A LURE OF FRESH SPRINGBOK,

BUT THE SIGHT OF HUMAN FLESH WILL GET THE DOGS SALIVATING TOO

BECAUSE AFRICAN WILD DOGS CANNOT BE TAMED.

Massier: THEY ARE WILD.

YOU REALLY HAVE TO BE CAREFUL. YOU CANNOT TAKE IT LIGHTLY.

YOU'VE ALWAYS GOT TO KEEP A LOOKOUT

BECAUSE THEY'RE VERY QUICK.

SO IT IS QUITE A HAIRY SITUATION,

BUT WE SHOULD MAKE IT OUT ALIVE, HOPEFULLY.

Narrator: HOPEFULLY?

IT LOOKS LIKE THEY'VE ALREADY PICKED UP THE SCENT

OF COLETTE AND THE SPRINGBOK LURE.

[ WILD DOGS YELPING ]

♪♪

THEY'RE COMING.

Narrator: THE HUNT IS ON,

AND THE DOGS EASILY KEEP PACE WITH THE TRUCK.

Massier: THEY CAN REACH SPEEDS OF 60 Ks PER HOUR,

WHICH IS INCREDIBLE.

Narrator: THAT'S NEARLY 40 MILES PER HOUR

AND NOT AS A SHORT SPRINT.

THE SECRET TO THEIR HUNTING SUCCESS IS,

THEY CAN SUSTAIN THEIR SPEED.

PREY LIKE ANTELOPE CAN OUTSPRINT THEM,

BUT THESE DOGS MAINTAIN THEIR SPRINT SPEED FOR UP TO 3 MILES.

LIKE LONG-DISTANCE CYCLING TEAMS,

THEY SWAP THE LEADER TO MAINTAIN THE PACE.

THIS DOG ON THE RIGHT COMES FROM THE BACK AND NOW TAKES THE LEAD.

Massier: THAT'S HOW THE PACK AS A WHOLE

REALLY MANAGES TO GO THESE LONG DISTANCES

THAT A CHEETAH COULD NEVER DO OR A LEOPARD OR EVEN A LION.

Narrator: FOR THE PREY, IT'S LIKE BEING CHASED

BY 10 FURRY TERMINATORS.

THEY JUST KEEP COMING.

NO MATTER HOW FAST YOU RUN OR YOU THINK YOU'RE RUNNING,

YOU'RE GOING TO TIRE, YOU'RE GOING TO SLOW DOWN,

BUT THESE GUYS ARE GOING TO KEEP GOING.

IT'S RELENTLESS.

Narrator: AND AS THE PREY TIRES, THE DOGS DO SOMETHING AMAZING.

THEY COMMUNICATE WITH EACH OTHER.

CONSTANT YELPS AND BODY-LANGUAGE CUES

SEND ORDERS ACROSS THE PACK,

ORGANIZING THE HUNTING PARTY INTO ATTACK POSITIONS.

THEIR TECHNIQUE IS TO ALL SURROUND THE PREY

AND CUT OFF THE WEAKEST.

THAT'S EXACTLY WHAT THEY'RE DOING.

THEY'RE SORT OF TRYING TO CUT US OFF AS A PIECE OF MEAT REALLY.

Narrator: DOGS MOVE TO TAKE OUT THE TARGET, FLANKING THE SIDES.

OTHERS ARE COMMANDED TO SPRINT FORWARD AND HEAD IT OFF.

SO THIS PIECE OF SPRINGBOK WE HAVE HERE

DOESN'T ACTUALLY STAND A CHANCE.

♪♪

Narrator: WILD DOGS' KILLER CATCHING TECHNIQUES

MEAN THAT NO MATTER HOW FAR YOU RUN,

THERE IS LITTLE CHANCE OF ESCAPE.

Massier: THEY ARE AFRICA'S MOST MAGNIFICENT, AMAZING HUNTERS.

I'M SO LUCKY TO BE ABLE TO SEE THIS IN ACTION.

Narrator: COMING UP: WHY NO PLACE

IS OFF-LIMITS TO A RAT

AND HOW PENGUINS CAN COMFORTABLY BE ON ICE 24-7.

Narrator: CHICAGO, THE WINDY CITY,

HOME TO BEARS, CUBS AND BULLS.

COME ON IN.

BUT THERE'S A NEW TEAM IN TOWN,

AND THEY'RE STEPPING UP AND TAKING OVER.

A RECENT STUDY CLAIMS THAT CHICAGO IS NOW

THE RAT CAPITAL OF AMERICA.

MANY BELIEVE IN ALL URBAN AREAS,

WE'RE ONLY EVER 6 FEET AWAY FROM ONE.

THERE'S PROBABLY ONE RIGHT NEXT TO YOU RIGHT NOW.

BUT WHY ARE WE ALWAYS JUST A FEW FEET AWAY FROM A RAT?

[ RAT SQUEAKS ]

THERE ARE 56 SPECIES OF RAT,

BUT THE BEST KNOWN AND MOST ABUNDANT IS THE BROWN RAT.

BROWN RATS DON'T LIVE IN THE WILD.

WHEREVER THERE ARE HUMANS, THEY KNOW THEY'LL FIND

BITS OF OLD BURGER, FINGER-LICKED CHICKEN

AND THE OCCASIONAL LOADED HOT DOG.

NOT YOU, SIR.

AND THEY MULTIPLY FAST.

A FEMALE BROWN RAT CAN PRODUCE 12 LITTERS A YEAR

WITH UP TO 22 PUPS EACH TIME.

WITHIN 3 MONTHS, HER BABIES CAN PRODUCE BABIES,

WHO ALSO PRODUCE BABIES,

WHICH MEANS A SINGLE PAIR OF BROWN RATS

CAN HAVE AS MANY AS 100 BABIES

AND 2,000 DESCENDANTS IN JUST 1 YEAR.

BUT THE FACT THERE ARE SO MANY ONLY PARTLY EXPLAINS

WHY WE'RE ALWAYS SO CLOSE TO THEM.

IT SEEMS RATS CAN GO ANYWHERE,

AND I MEAN ANYWHERE.

WE'VE COME UP WITH A STRING OF CHALLENGES TO TEST

JUST HOW EASY IT IS FOR RATS TO GET UP CLOSE WITH HUMANS.

MEET THE CHALLENGERS:

RANDY AND HIS RODENT BUDDY, ROCKY.

FIRST TEST: HOW SMALL A HOLE CAN A RAT GET THROUGH?

INCREDIBLY, RATS CAN SQUEEZE THROUGH A HOLE

AS SMALL AS A QUARTER.

THE RATS' RIBS ARE HINGED AT THE SPINE,

ALLOWING THEM TO TEMPORARILY COLLAPSE UNDER THE PRESSURE.

THE GENERAL RULE IS, IF ITS HEAD FITS, THEN THE BODY WILL FOLLOW.

BETTER BLOCK UP THOSE BASEBOARDS.

NOW, WILL THIS CHASM STOP THEM?

♪♪

INCREDIBLE.

RATS CAN JUMP 2 1/2 FEET IN THE AIR.

THAT'S THE EQUIVALENT OF THE AVERAGE MAN

JUMPING 11 FEET OFF THE GROUND.

HANDY FOR FINDING FOOD IN ALL THOSE HIGH PLACES.

RANDY IS TAKING A WELL-EARNED BREATHER,

BUT WILL ROCKY TAKE ON THE HIGH-WIRE CHALLENGE?

NICE WORK.

WHOA.

ROCKY NEARLY FELL, BUT NOT TO WORRY:

HE HAS INCREDIBLE BALANCE THANKS TO HIS SUPERSIZED TAIL.

A RAT'S TAIL FOLLOWS A SIMILAR PRINCIPAL

AS A TIGHTROPE WALKER'S POLE.

IT WORKS AS A COUNTERBALANCE.

IF HE TIPS ONE WAY,

THE TAIL SWINGS IN THE OPPOSITE DIRECTION.

THIS BALANCING TECHNIQUE ALLOWS THE RAT

TO RUN ACROSS POWER LINES AND INTO YOUR HOME.

APPROACHING THE FINAL CURVE,

ROCKY IS COMMITTING THE ULTIMATE PHOBIC NIGHTMARE.

A RAT CAN SCURRY UP SEWER PIPES AND INTO YOUR TOILET.

RATS ARE EXCELLENT SWIMMERS AND CAN TREAD WATER FOR 3 DAYS.

THEY CAN EVEN SURVIVE BEING FLUSHED BACK DOWN

BECAUSE THEY CAN HOLD THEIR BREATH UNDERWATER FOR 3 MINUTES.

RATS DON'T ALWAYS GET A GOOD RAP,

BUT WHEN IT COMES TO SNIFFING OUT FOOD,

THERE'S NO HOME, BATHROOM OR KITCHEN THAT'S OFF-LIMITS,

WHICH IS WHY RANDY AND HIS AGILE BUDDIES

ARE ALWAYS JUST A FEW FEET AWAY.

LUNCH IS ON ME, FELLAS.

COMING UP: A PENGUIN BABY WITH ANTIFREEZE FEET.

Narrator: ANTARCTICA, THE COLDEST PLACE ON EARTH.

TEMPERATURES DOWN HERE PLUMMET TO A RECORD

MINUS 135.8 DEGREES FAHRENHEIT.

IMAGINE STANDING IN THOSE TEMPERATURES.

COLD YET?

WELL, NOW IMAGINE STANDING THERE WITHOUT SHOES OR SOCKS,

JUST BARE FEET.

AFTER JUST 2 MINUTES WITHOUT WARM BLOOD

PUMPING AROUND YOUR FEET,

YOUR TOES START TO FREEZE AND WILL EVENTUALLY FALL OFF.

BUT AMAZINGLY, THERE IS ONE ANIMAL

WHOSE FEET ARE FINE IN THIS DEEP FREEZE:

THE PENGUIN.

THEY STAND AROUND FOR MONTHS WITH BARE TOES,

JUST CHILLING OUT.

SO WHY DON'T PENGUINS' FEET FREEZE?

THESE ICE SHEETS ARE HOME TO AN ESTIMATED

40 MILLION PENGUINS,

HUGE GROUPS OF SMALL SOUTHERN ROCK HOPPERS,

KINGS AND THE BIGGEST MOST ICONIC EMPERORS.

TO KEEP THEIR BODIES WARM IN THE FREEZING COLD,

ALL THESE BRILLIANT BIRDS HAVE AN INSULATING LAYER OF FAT

AND THICK DOWNY FEATHERS THAT TRAP WARM AIR AGAINST THEIR SKIN

EXCEPT ON THEIR FEET.

LOOK AT THEM!

THOSE TOES HAVE NO FEATHERS, NO FAT,

NOTHING TO KEEP THEM WARM.

INSTEAD, CLEVER INTERNAL

PLUMBING KEEPS THEIR TOES TOASTY.

BLOOD VESSELS BRING COLD BLOOD UP FROM THE BARE FEET.

WARM BLOOD COMES DOWN FROM THE FEATHER-COATED BODY.

WHERE THE BLOOD MEETS, THE VESSELS WRAP AROUND EACH OTHER,

ALLOWING THE HOT BLOOD TO WARM UP THE COLD BLOOD.

IT MEANS BLOOD GOING UP INTO THE BODY ISN'T COLD,

AND BLOOD PUMPING DOWN IS WARM ENOUGH

TO KEEP THEIR TOES FROM FREEZING.

IF YOU'RE INTO SCIENCE, IT'S CALLED

THE COUNTERCURRENT HEAT EXCHANGE.

BUT WHEN FREEZING ANTARCTIC BLIZZARDS COME IN,

EVEN THIS BIOLOGICAL BRILLIANCE NEEDS HELP.

TO HEAT THEIR TOES, PENGUINS SIT ON THEIR BACKSIDES

TO RAISE THEIR FEET OFF THE COLD ICE

AND WRAP THEM AND THEIR YOUNG IN THEIR FEATHERS.

IT'S THE EQUIVALENT OF PENGUIN SLIPPERS.

THESE FEET-WARMING TACTICS

MIGHT NOT GIVE THEM A GRIP ON THE ICE,

BUT IT DOES GIVE THEM HAPPY FEET.
