Narrator: ANIMALS...

DO THE MOST INCREDIBLE THINGS...

LIKE THIS...

AND THIS.

I BET YOU'RE WONDERING, "HOW DO THEY DO THAT?"

WE'RE REVEALING ANIMALS' BIGGEST SECRETS --

LIKE, WHY DO LIONS LAZE ABOUT WHILE LIONESSES DO ALL THE WORK?

WHY ARE HAGFISH THE MOST DISGUSTING ANIMALS

ON THE PLANET?

AND HOW DO DOGS KNOW WHEN WE NEED A HUG?

THESE WONDERS AND MORE.

"HI. RALPH THE PUG HERE.

LATELY, I'VE BEEN HAVING THIS RECURRING NIGHTMARE.

MY PERSON IS STUCK IN THIS TINY ROOM,

AND SHE'S CRYING HER EYES OUT.

I CAN'T EVEN GET IN AND COMFORT HER

WITH ONE OF MY SPECIAL PUG HUGS.

HOLD ON, MOM. I'M COMING."

OKAY, SO, RALPH WASN'T ACTUALLY HAVING A NIGHTMARE.

HE AND HIS CANINE CHUMS ARE BEING TESTED TO SEE

IF THEY CAN RECOGNIZE UNHAPPINESS IN THEIR OWNERS.

OKAY. LET'S DO IT.

FIRST, A GROUP OF HAPPY, HUMMING DOG OWNERS

SIT BEHIND A GLASS DOOR.

IN COME THE DOGS.

ALTHOUGH THE GLASS IS SEPARATING THEM,

THE DOGS SEEM PRETTY HAPPY, TOO.

BUT SEE HOW THAT TEST COMPARES WITH THIS ONE.

Woman: ALL RIGHT. YOU CAN START.

OKAY. CUE THE SOBS.

[ ALL CRYING ]

NOW, RELEASE THE HOUNDS.

DESPERATE TO COMFORT THEIR OWNER,

THIS TIME, THE DOGS BURST THROUGH THE DOOR.

Woman: GOOD BOY! GOOD BOY!

-GOOD BOY. -HI, BUDDY!

Narrator: AND RALPH GETS TO ADMINISTER HIS SPECIAL PUG HUG.

THIS TEST PROVES WHAT EVERY DOG OWNER KNOWS --

DOGS NOT ONLY KNOW WHEN WE'RE FEELING BLUE,

THEY WANT TO DO SOMETHING ABOUT IT.

SO, HOW DO DOGS KNOW WHEN YOU'RE SAD?

THIS CHARMING CHAP IS OAKLEY.

Amber: YEAH. THAT'S A GOOD BOY.

Narrator: OAKLEY IS A 5-YEAR-OLD RESCUE.

HIS BEST FRIEND, DOG TRAINER AMBER OLIVER,

IS ON A MISSION TO DEVELOP HIS AMAZING EMPATHETIC INSTINCTS.

OAKLEY IS MY BEST FRIEND, BUT HE'S ALSO MY SERVICE DOG.

HE HAS BEEN TRAINED TO HELP PEOPLE LIKE ME,

WITH SOCIAL ANXIETY.

Narrator: AMBER IS ONE OF 50 MILLION AMERICANS

WHO SUFFER FROM THIS SEVERE CONDITION.

OFTEN MISREAD AS EXTREME SHYNESS,

THOSE WITH THE DISORDER CAN SUFFER FROM PANIC ATTACKS

IN PUBLIC SITUATIONS.

BUT RATHER THAN HIDING AT HOME,

AMBER HAS STARTED TRAINING DOGS TO HELP HER AND OTHER SUFFERERS.

I'M NOT WORRIED ABOUT HAVING AN ANXIETY ATTACK,

BECAUSE I KNOW THAT HE'S GOING TO BE THERE

TO BREAK THE CYCLE AND TAKE CARE OF ME.

THEIR ABILITY TO DO THESE THINGS IS JUST ASTOUNDING.

IT'S REALLY COOL.

Narrator: TO READ AMBER'S EMOTIONS,

OAKLEY RELIES ON HIS SUPER SENSE.

DOGS HAVE REALLY AMAZING NOSES,

AND THEY CAN BE TAUGHT TO RESPOND

TO CHEMICAL CHANGES IN YOUR BODY.

SOMETIMES, A DOG CAN RESPOND TO JUST SMELLING SOME SWEAT.

Narrator: BEFORE A PANIC ATTACK KICKS IN, OUR HEARTS BEAT FASTER.

ADRENALINE PUMPS THROUGH OUR BLOOD,

AND WE SWEAT MORE.

INCREDIBLY, THE CHEMICALS IN OUR SWEAT

ARE SLIGHTLY DIFFERENT

DEPENDING ON WHETHER WE'RE HAPPY, OR SAD, OR STRESSED.

OAKLEY KNOWS WHEN TO HELP

BECAUSE HIS SUPER SENSITIVE NOSE --

10,000 TIMES MORE SENSITIVE THAN OUR OWN --

CAN DETECT THESE MINUSCULE CHANGES IN OUR ODOR.

AND THE CLEVER CANINE CAN DETECT OTHER CHANGES, TOO.

OAKLEY HAS BEEN TRAINED TO PAY ATTENTION TO LABORED BREATHING,

FOR INSTANCE, AS THAT'S A REALLY EASY SIGN

THAT I'M ABOUT TO HAVE A PANIC ATTACK.

SO, IF I START HAVING LABORED BREATHING,

HE JUMPS INTO ACTION.

Narrator: LET'S SEE WHAT HAPPENS

WHEN AMBER SIMULATES A PANIC ATTACK.

ALL SHE'S GOING TO DO IS BREATHE FASTER

AND THINK ANXIOUS THOUGHTS.

♪♪

♪♪

OAKLEY PICKS UP ON AMBER'S EMOTION.

GOOD BOY.

AND THEN, HIS TRAINING KICKS IN.

SO, WHAT OAKLEY IS DOING RIGHT NOW

IS CALLED "DEEP-PRESSURE THERAPY."

AND THIS IS REALLY HELPFUL, BECAUSE HE'S PRESSING HIS WEIGHT

DOWN ON MY LAP AND ON MY CHEST, WHICH IS WHY HIS PAW IS UP HERE.

AND THIS IS REALLY HELPFUL TO HELP CALM ME DOWN

AND KIND OF GROUND ME

AND HELP ME PAY ATTENTION TO MY BREATHING.

AW.

OKAY.

VERY SWEET.

Narrator: A DOG'S AMAZING SENSE OF SMELL AND HEARING

ALLOWS HIM TO READ OUR EMOTIONS ALMOST INSTANTLY.

AND WHAT'S TRULY INCREDIBLE,

AND BEYOND THE REALM OF MERE SCIENCE,

IS THE FACT THAT DOGS LIKE OAKLEY

WANT TO HELP US IF THEY CAN.

DOGS REALLY ARE MAN AND WOMAN'S BEST FRIEND.

IN A LION'S HOUSEHOLD,

THE SHARE OF CHORES DOESN'T LOOK FAIR.

WHILE THE LIONESSES GO OUT AND HUNT --

BRINGING HOME THE BACON, OR WARTHOG --

THE BLOKES ARE SEEMINGLY GOOD FOR NOTHING,

AND LIE AROUND WAITING FOR DINNER TO BE SERVED.

SO, WHY DO ONLY LIONESSES HUNT?

OUT IN AFRICA'S SAVANNA,

THE JOB OF PROVIDING THE EQUIVALENT OF 15 T-BONE STEAKS

FOR EACH OF THE LIONS IN THE 20-CAT PRIDE

FALLS SQUARELY IN THE PAWS OF THE LIONESSES.

HER HECTIC SCHEDULE INVOLVES LICKING THE KIDS CLEAN,

SCHOOLING THE TEENS, FINDING A WATER HOLE,

AND ON TOP OF THAT, THEY HAVE TO SPEND

8 HOURS A DAY SHOPPING FOR WILDEBEEST AND STUFF.

THEY DO ALL THAT AND STILL MANAGE

TO LOOK GOOD ON THE PRAIRIE.

THE MALES, HOWEVER -- WELL, THEY HAVEN'T EVEN GOT

A BALLGAME ON THE TV TO KEEP THEM AWAKE.

IT DOESN'T SOUND FAIR,

BUT THE LIONESSES ARE PROBABLY GLAD

THE MALES AREN'T AROUND TO SLOW THINGS DOWN.

FEMALES ARE SMALLER, MORE NIMBLE, AND BETTER ORGANIZED.

THEY WORK TOGETHER AS A TEAM,

CORRALLING THEIR PREY INTO DEADLY TRAPS.

AND WHEN IT'S TIME TO POUNCE, THEIR STREAMLINED BODIES

ACCELERATE TO 50 MILES AN HOUR IN JUST A FEW SECONDS.

THE LIONS ARE MUCH HEAVIER, AND TRUTH BE TOLD, A BIT SLOW.

AND WITH A GLORIOUS MANE THAT'S EASILY SPOTTED,

WELL, THIS GUY IS PRETTY USELESS IN A HUNTING PARTY.

SO, WHY DO THE LIONESSES PUT UP WITH HIM?

WELL, THE LAZY LUMP HAS A VERY IMPORTANT ROLE TO PLAY,

BECAUSE, WHILE THE LIONESSES HUNT,

HE'S KEEPING THE FAMILY SAFE AND FIGHTING OFF INTRUDERS.

IN THE SAVANNA, CIRCLING THE PRIDE ARE JEALOUS MALES.

THESE BACHELORS AREN'T HAPPY

BECAUSE THEY HAVE TO HUNT FOR THEMSELVES.

THEY WOULD LIKE NOTHING MORE THAN TO GET COZY

WITH ALL THESE LOVELY LIONESSES.

THEIR NOT-SO-SECRET PLAN IS TO OUST THE ALPHA MALE,

HOOK UP WITH THE PRIDE, AND MAKE THEIR OWN CUTE LITTLE CUBS.

IF THE MALE SUCCEEDS IN TAKING OVER,

SOMETHING TRULY HORRIFIC FOLLOWS.

TO STOP THE MUMS FROM WASTING TIME NURTURING CUBS

BELONGING TO THE PREVIOUS INCUMBENT,

THE NEW KING OF THE BLOCK WILL KILL THE YOUNGSTERS.

SEEMS CRUEL, DOESN'T IT?

SO, TO PROTECT THE CUBS FROM OTHER JEALOUS MALES,

DAD HAS TO USE HIS BULK, CLAWS, AND TEETH TO FIGHT THEM OFF.

IN FACT, THE REASON THE LIONESSES HAVE LATCHED ON

TO THIS LAZY GUY

IS BECAUSE HE'S BIG ENOUGH TO PROTECT THEIR CUBS

FROM ALL THE OTHER HORRIBLE MALE LIONS OUT THERE.

SO, ALTHOUGH THE MUMS ARE DOING THE LION'S SHARE,

DEEP DOWN, THEY KNOW HE'S DOING AN IMPORTANT JOB

KEEPING THEIR CUBS SAFE.

MIND YOU, A BIT MORE HOUSEWORK WOULD GO A LONG WAY.

COMING UP, THE FIGHTER ACES OF THE BIRD WORLD,

THE MOST REPULSIVE CREATURE IN THE UNDERWORLD,

AND CAN THESE GUYS REALLY SURVIVE AN APOCALYPTIC WORLD?

♪♪

Narrator: HUMANS HAVE ALWAYS DREAMT OF FLYING LIKE A BIRD,

AND AS FOR BIRDS,

WELL, THEY DREAM OF FLYING LIKE THESE GUYS.

♪♪

SMALL YET MIGHTY,

HUMMINGBIRDS ARE THE FIGHTER ACES OF THE BIRD WORLD,

BUT AMONG ALL THEIR INCREDIBLE ACROBATIC POWERS,

ONE STANDS OUT AS UNIQUE.

THEY'RE THE ONLY BIRD ON THE PLANET ABLE TO FLY IN REVERSE.

SO HOW DO HUMMINGBIRDS FLY BACKWARDS?

♪♪

FOUND IN NORTH AND SOUTH AMERICA

AND WEIGHING AS LITTLE AS A PENNY,

HUMMINGBIRDS' SHIMMERING BEAUTY

IS ECLIPSED ONLY BY THEIR SKILL IN THE AIR.

Dr. Clark: THEY'RE LITTLE FIGHTER JETS.

THEY'RE CAPABLE OF OUTMANEUVERING ANY OTHER BIRD.

THEIR TOP SPEED IS AROUND

50 MILES AN HOUR IN LEVEL FLIGHT.

THE ACCELERATIONS THEY HIT, ALL OF THAT IS JUST --

IT'S AMAZING WHAT THEY CAN DO.

Narrator: BUT EXPERT DR. CHRIS CLARK

KNOWS THE TINY BIRDS' AGILITY COMES AT A PRICE.

FLAPPING THEIR WINGS SO ENERGETICALLY IS HUNGRY WORK,

AND IF A HUMMINGBIRD CAN'T REFUEL

AT LEAST ONCE EVERY 10 MINUTES, IT WILL PERISH.

CHRIS IS GOING TO USE

THE HUMMINGBIRDS' INSATIABLE APPETITE

TO HELP HIM FIGURE OUT HOW THEY FLY BACKWARDS.

HE'S SET UP A FEEDER INSIDE A WIND TUNNEL,

WHICH WILL, HOPEFULLY, LURE A HUMMINGBIRD

IN FRONT OF HIS SLOW-MOTION CAMERAS.

CAMERA, CHECK. LIGHTS, CHECK.

OKAY. CUE TALENT.

MEET LOUIE, A GORGEOUS ANNA'S HUMMINGBIRD

FRESHLY CAUGHT THIS MORNING.

ONE OF THE WAYS YOU CAN TELL IT'S AN ANNA'S HUMMINGBIRD

IS FROM THE PURPLE COLORS ON BOTH ITS THROAT

AND ON THE TOP OF HIS HEAD.

Narrator: FIRST, CHRIS CHECKS TO SEE

IF LOUIE CAN DRINK THE SUGAR WATER FROM THE FEEDER.

UNLIKE MOST BIRDS, HE FIGURED THAT OUT ALMOST IMMEDIATELY.

Narrator: IT'S VITAL THAT LOUIE STAYS STILL AS HE FEEDS

BECAUSE HE HAS ONE OF THE WEIRDEST, MOST DELICATE

AND, RELATIVE TO ITS SIZE, LONGEST TONGUES IN NATURE.

Dr. Clark: IMAGINE FLYING AROUND WITH A ENORMOUS STRAW

ON THE FRONT OF YOUR HEAD, AND YOU HAVE TO AIM THAT STRAW

AND GET IT INTO AN EXACT SPOT TO DRINK,

AND YET THEY'RE ABLE TO DO IT EFFORTLESSLY.

OH, HERE HE COMES AGAIN.

Narrator: IF YOU SCALED UP

HIS HAIRY, FORKED TONGUE TO HUMAN SIZE,

IT WOULD BE ABOUT 3 FEET LONG

AND ABLE TO SUCK UP NEARLY A PINT IN A SECOND.

SORRY, LOUIE. THIS ISN'T A RESTAURANT.

IT'S A WIND TUNNEL.

Dr. Clark: SO, I WILL GO AHEAD AND TURN IT ON.

Narrator: CHRIS BLASTS HIM WITH A FORCEFUL 20-MILE-AN-HOUR WIND.

[ WIND RUSHING ]

LOUIE IS SO LIGHT, HE'S BLOWN TO THE BACK OF THE CAGE.

OKAY. HE'S BACK.

BUT JUST AS CHRIS WAS HOPING,

THE LITTLE ROCKET IS RUNNING OUT OF FUEL.

THE TRICK IS THAT HE HAS TO TURN AROUND TO GO TO THE FEEDER,

AND TO DO THAT, HE'LL HAVE TO FLY BACKWARDS,

AND WE'RE NOT SURE HE CAN DO IT AT THIS SPEED OR NOT.

WE THINK HE CAN.

Narrator: BECAUSE OF THE WIND BLOWING HIM TOWARD THE FEEDER,

LOUIE WILL HAVE TO FLY BACKWARDS AT 20 MILES AN HOUR

JUST TO STAY STILL ENOUGH TO FEED ON THE SUGAR WATER.

COME ON, LOUIE.

♪♪

NEARLY. GO ON.

Dr. Clark: OH, OH, HE'S -- OH, THERE WE GO.

OH, LOOK AT THAT. THAT IS SO COOL.

Narrator: INCREDIBLE.

CHRIS' SLOW-MOTION CAMERAS REVEAL SOMETHING AMAZING.

LOUIE ISN'T ONLY FLAPPING HIS WINGS UP AND DOWN.

Dr. Clark: IT'S A BIT DIFFERENT

FROM HOW OTHER BIRDS DO IT WHEN THEY FLY.

Narrator: MOST BIRDS PRODUCE LIFT

ONLY WITH A DOWNWARD FLAP OF THEIR WINGS,

BUT HUMMINGBIRDS HAVE BORROWED AN IDEA FROM AN UNLIKELY SOURCE.

THEY FLY MORE LIKE AN INSECT DOES THAN DO OTHER BIRDS.

INSECTS HAVE MORE OR LESS A FLAP WING

THAT THEY JUST FLAP BACK AND FORTH,

AND HUMMINGBIRDS BASICALLY DO THE SAME THING.

Narrator: JUST LIKE INSECTS, LOUIE IS TRACING OUT

A FIGURE-8 PATTERN IN THE AIR.

HALF THE FIGURE-8 IS MADE WHEN THE WING GOES DOWN,

AND THEN THE OTHER HALF OF THE FIGURE-8

IS WHEN THEY TURN THEIR WING OVER,

AND THEN THEY GO DOWN AGAIN IN THE OTHER DIRECTION,

AND THAT LETS HIM GET THRUST

BOTH WHEN HE FLAPS HIS WINGS DOWN

AND ALSO WHEN HE FLAPS HIS WINGS UP.

Narrator: TO GO IN REVERSE, LOUIE SIMPLY HAS TO LEAN BACK.

Dr. Clark: WHEN HE WANTS TO FLY BACKWARDS, HE HAS TO FLAP

WITH THEM TILTED UP TO DIRECT THE AIR BACKWARDS

SO THAT HE GOES BACKWARDS.

Narrator: TO PULL THIS OFF,

AN INCREDIBLE 25% OF LOUIE'S BODY WEIGHT

IS MADE UP OF HUGE, POWERFUL CHEST MUSCLES,

WHICH ALLOW HIM TO FLAP HIS WINGS

AN ASTONISHING 80 TIMES A SECOND.

WITHOUT THEIR HOVERING SUPERPOWER,

HUMMINGBIRDS WOULDN'T BE ABLE TO GATHER NECTAR.

THE ONLY PROBLEM IS, HOVERING USES UP SO MANY CALORIES,

THEY HAVE TO DRAIN THE NECTAR FROM 1,000 FLOWERS EVERY DAY

JUST TO KEEP THEIR ENGINE GOING.

NO REST FOR THE WICKED, EH?

TIME TO LET LOUIE GET BACK TO HIS DAY JOB.

YOU WERE GREAT. OH.

Narrator: SO LONG, LOUIE.

COMING UP, WHY HAGFISH

ARE THE MOST DISGUSTING ANIMALS ON THE PLANET.

Narrator: THE ANIMAL KINGDOM HAS AN ABUNDANT SUPPLY OF GROSS.

LIZARDS THAT SHOOT STREAMS OF FOUL-SMELLING BLOOD

FROM THEIR EYES...

GULLS THAT PROJECTILE-VOMIT ON UNSUSPECTING PREDATORS.

OVER A WEEK WITHOUT A HEAD.
