Narrator: ANIMALS...

DO THE MOST INCREDIBLE THINGS.

[ GOAT BLEATS ]

LIKE THIS...

AND THIS.

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

WE'RE REVEALING ANIMALS'
BIGGEST SECRETS, LIKE...

HOW ARE VULTURES
IMMUNE TO DISEASE?

HOW DO KOALAS KEEP COOL
IN 100 DEGREE HEAT?

AND WHAT'S THE SECRET
BEHIND A FROG'S AMAZING TONGUE?

THESE WONDERS AND MORE ON...

KOALAS SPEND MOST OF THEIR LIVES
HIGH UP IN EUCALYPTUS TREES

IN THE AUSTRALIAN WOODLANDS.

THESE EXPERT CLIMBERS
ARE PERFECTLY ADAPTED

FOR THE HIGH LIFE.

TWO CLAWED THUMBS ON EACH PAW
PROVIDE A FIRM GRIP,

GIVING THEM THE CONFIDENCE
TO RELAX

WHILE DANGLING DOZENS
OF FEET IN THE AIR.

BUT WHAT THEY'RE NOT SO WELL
ADAPTED FOR IS THE HEAT.

THAT BIG FURRY COAT
JUST DOESN'T SUIT

THE EXTREME DAYTIME TEMPERATURES

THAT SOMETIMES CLIMB
TO 115 DEGREES.

WORSE FOR THESE AUSSIE FUR BALLS
IS THAT ABOVE 105 DEGREES,

THE BODY STARTS TO SHUT DOWN.

SO HOW DO KOALAS KEEP COOL?

TREE-HUGGING KOALAS
ARE INCREDIBLY CUTE,

BUT THERE IS PURPOSE
BEHIND THIS ADORABILITY

THAT CAN BE REVEALED WITH THE
HELP OF THERMAL IMAGING CAMERAS.

KOALAS LOVE EUCALYPTUS TREES,
NOT JUST FOR THE LEAVES,

BUT FOR THE TRUNKS, TOO.

THAT'S BECAUSE THE TRUNK
OF THE EUCALYPTUS

CAN BE UP TO 10 DEGREES COLDER
THAN THE SURROUNDING AIR.

SO WHAT DO KOALAS DO?

THEY GIVE THE TREE UP BIG HUG.

THE REASON THE TREES ARE COLDER
IS BECAUSE WATER HEATS UP

AND COOLS DOWN
MORE SLOWLY THAN AIR.

AND SOME TREES CAN CONTAIN
MORE THAN 70% WATER.

BUT TREES LIKE THE EUCALYPTUS
HAVE AN EXTRA COOL SETTING,

AND THAT'S BECAUSE THEY SUCK UP
FRESH GROUNDWATER

FROM THE COOLER ROOTS
TO THEIR LEAVES.

FOR KOALAS, IT'S LIKE THEY'RE
HUGGING A GIANT POPSICLE.

BUT THEIR LIFESAVING HUG

MUST PUT AS MUCH
OF THEIR SURFACE AREA

INTO CONTACT WITH THE TREE
AS POSSIBLE

TO GET THE MAXIMUM
REFRIGERATED EXPERIENCE.

IF THEY GET THAT HUG JUST RIGHT,
IT CAN TRANSFER A PHENOMENAL

50% OF THEIR BODY HEAT
INTO THE TREE.

AND WHEN THE TOPS OF THE TREES
HEAT UP IN THE SUN,

KOALAS HAVE A PLAN.

THEY CLIMB DOWN
TO THE LOWER BRANCHES,

WHERE THE GROUNDWATER IS COOLER.

SO IT MAY LOOK LIKE
ADORABLE TREE HUGGING,

BUT IT'S ACTUALLY
THE BEST AIR CONDITIONING

THE OUTBACK CAN OFFER.

AFRICAN ELEPHANTS LIVE
IN LARGE, TIGHT-KNIT FAMILIES.

A SINGLE HERD CAN HAVE
AS MANY AS 70 ELEPHANTS.

AND WITH THAT MANY MOUTHS
TO FEED,

THE HERD NEEDS TO COVER
A 4,000-SQUARE-MILE TERRITORY

TO FIND ENOUGH FOOD.

THAT'S NINE TIMES THE SIZE
OF LOS ANGELES.

ALTHOUGH INDIVIDUALS WILL OFTEN
WANDER AWAY FROM THE HERD

AND DEEP INTO THIS TERRITORY...

...THEY ALWAYS SEEM TO FIND
THEIR WAY BACK TOGETHER.

IT'S AS IF THE ELEPHANTS
HAVE TOLD EACH OTHER

WHERE THEY'RE LOCATED.

SO, CAN ELEPHANTS COMMUNICATE
WHEN THEY'RE MILES APART?

[ ELEPHANT GROWLS ]

AT THE ADVENTURES WITH ELEPHANTS
SANCTUARY IN SOUTH AFRICA,

DR. ANGELA STOEGER-HORWATH

IS HOPING TO ANSWER
THIS QUESTION

BY TRYING TO RECORD THE SOUNDS

OF SEPARATED ELEPHANTS
COMMUNICATING.

SHE SPENT 10 YEARS
STUDYING THE COMPLEX SOUNDS

THAT MAKE UP ELEPHANT LANGUAGE.

Stoeger-Horwath:
ELEPHANTS ARE SPECIAL SPECIES

WHEN IT COMES
TO VOCAL COMMUNICATION.

I'M INTERESTED IN WHAT THEY MEAN
AND HOW THEY PRODUCE THE SOUNDS.

Narrator: SHE'S DEVISED A TEST
THAT INVOLVES SPLITTING A HERD

OF RESCUE ELEPHANTS
INTO TWO GROUPS.

SO, WE'LL TAKE MESSINA
AND THE BABIES THAT WAY.

WARDENS FOLLOW ONE GROUP
OF ELEPHANTS

AS THEY WANDER
OVER TWO MILES AWAY.

ANGELA AND RESEARCHER ANTON STAY
WITH THE REMAINING ELEPHANTS

TO SEE IF THEY CAN COMMUNICATE
EVEN OVER THIS DISTANCE.

TO EAVESDROP ON
ANY LONG-DISTANCE CHATTER,

THEY NEED SOME HIGHLY SENSITIVE
RECORDING EQUIPMENT.

THESE MICROPHONES
CAN DETECT FREQUENCIES

ABOVE AND BELOW
WHAT OUR HUMAN EARS CAN HEAR.

THE RESEARCHERS SET UP
NEXT TO ONE ADULT FEMALE

AND TWO YOUNG MALES.

ONE OF THEM
IS 23-YEAR-OLD BULL CHOVA.

WITH THE OTHER GROUP
NOW OVER TWO MILES AWAY

AND COMPLETELY OUT OF SIGHT,

CHOVA APPEARS TO BE LOOKING
FOR THE REST OF HIS HERD.

BUT HE'S NOT SAYING ANYTHING.

OR IS HE?

OH. DO YOU HEAR THAT?

ANGELA'S RECORDING EQUIPMENT

HAS DETECTED SOMETHING THE HUMAN
EAR COULD NORMALLY NEVER HEAR.

TO US, IT SOUNDS LIKE NOTHING,
BUT THROUGH THE HEADPHONES,

ANGELA CAN HEAR A SERIES
OF AMPLIFIED INFRASONIC CALLS.

[ ELEPHANT GRUMBLING ]

OH, YEAH,
THAT'S GREAT.

WE HEAR SOUNDS BETWEEN
20 AND 20,000 HERTZ,

BUT CHOVA'S BASSY RUMBLES
ARE 12 HERTZ,

THREE OCTAVES LOWER
THAN THE DEEPEST HUMAN VOICE.

AND THIS IS POSSIBLE
THANKS TO THE SCALE

OF AN ELEPHANT'S
UNIQUELY LARGE ANATOMY.

LIKE MANY ANIMALS,
AFRICAN ELEPHANTS

CREATE SOUND BY EXHALING AIR
OVER THEIR VOCAL CORDS.

BUT AT 3 INCHES LONG,
AN ELEPHANT'S VOCAL CORDS

ARE EIGHT TIMES BIGGER
THAN A HUMAN'S

AND CAN PRODUCE MUCH DEEPER,
LOWER FREQUENCIES,

BELOW THE RANGE
OF HUMAN HEARING.

THE AIR ALSO REVERBERATES
IN A HUGE CHAMBER

CREATED BY THE MOUTH
AND 7-FOOT-LONG TRUNK,

WHICH AMPLIFIES
THE LOW-FREQUENCY SOUND.

AND THE LOWER THE FREQUENCY
OF THE SOUND WAVES,

THE FARTHER THEY CAN TRAVEL.

Stoeger-Horwath: THE DISTANCE
THAT THESE RUMBLES CAN TRAVEL

IS ESTIMATED
OF ABOUT 4 KILOMETER.

Narrator:
THAT'S 2 1/2 MILES.

AND IN COOLER
NIGHT TEMPERATURES,

A LOW-FREQUENCY ELEPHANT CALL
COULD TRAVEL UP TO 6 MILES.

THAT'S LIKE A BANKER
ON WALL STREET SAYING HELLO

AND BEING HEARD
ALL THE WAY IN BROOKLYN.

[ ELEPHANT GRUMBLING ]

AND CHOVA'S SILENT CALLS
SEEM TO BE SAYING SOMETHING,

BECAUSE IT APPEARS HE CAN HEAR
THE OTHERS CALLING BACK.

[ ELEPHANT GRUMBLING ]

I'M PRETTY SURE
THAT HE IS LISTENING,

BECAUSE HE SPREAD HIS EARS.

SO, THE EARS REALLY HELP HIM
TO LOCALIZE THE SOUND.

Narrator:
CHOVA'S 4-FOOT-WIDE EARS

FUNNEL THE LOW-FREQUENCY SOUNDS
INTO HIS EAR CANALS.

HIS MASSIVE EARS AND HEAD
HELP HIM PINPOINT

WHERE THE CALLS ARE COMING FROM.

[ ELEPHANT GROWLING ]

♪♪

CHOVA IDENTIFIES
THE ORIGIN OF A SOUND

DUE TO THE
FRACTION-OF-A-SECOND DELAY

BETWEEN IT HITTING ONE EAR,
THEN THE OTHER.

BECAUSE THE DISTANCE
BETWEEN ELEPHANT EARS

IS FIVE TIMES
THE DISTANCE BETWEEN OURS,

THEY CAN USE
THIS EXAGGERATED DELAY

TO MORE ACCURATELY DETERMINE
THE SOURCE OF THE SOUND.

THIS UNIQUE METHOD OF BOTH
CREATING AND HEARING INFRASOUND

MEANS ALTHOUGH ELEPHANTS
MAY BE PHYSICALLY MILES APART,

THEY CAN ALWAYS STAY IN TOUCH.

[ ELEPHANTS TRUMPETING ]

AND WHATEVER CHOVA'S
LAST CALL WAS,

IT'S BROUGHT THE REST OF
THE HERD STRAIGHT BACK TO HIM.

THERE'S ONLY ONE THING
AN ELEPHANT LOVES

MORE THAN A GOOD, OLD WANDER
AROUND THEIR TERRITORY,

AND THAT'S GETTING
BACK TOGETHER AGAIN.

[ ELEPHANT GRUMBLING ]

COMING UP, WHAT'S THE SECRET

OF THE FROG'S AMAZING TONGUE?

HOW DO VULTURES
SURVIVE A TOXIC MEAL?

AND WHAT'S THIS SPIDER'S SECRET
TO LONG LIFE?

Narrator:
WHEN IT COMES TO CATCHING BUGS,

FROGS HAVE GOT IT LICKED.

SUPER-STRETCHY TONGUES BLAST OUT

FIVE TIMES FASTER
THAN THE BLINK OF AN EYE.

AND ONCE IT STICKS,

THERE'S NO GETTING AWAY.

WHAT'S THE SECRET
BEHIND A FROG'S AMAZING TONGUE?

SO THERE'S BLACK PANTHER,

SPIDERMAN, BATMAN,

BUT WHY NO SUPERHERO NAME
FOR A FROG?

FROGS CAN SECRETE POISON.

THEY CAN HAVE INVISIBLE SKIN,

AND THEY CAN JUMP 20 TIMES
THE LENGTH OF THEIR OWN BODY.

BUT FOR BIOMECHANICS ENGINEER
DR. ALEXIS NOEL,

A FROG'S GREATEST SUPERPOWER

IS SOMETHING THEY ALL HAVE --

THAT INCREDIBLE TONGUE.

THEIR TONGUES ARE JUST AMAZING.

YOU KNOW, HOW ARE THESE FROGS
ABLE TO SNATCH INSECTS

RIGHT OUT OF THE AIR?

HOW ON EARTH DO THESE TONGUES
ACTUALLY STICK?

Narrator: FOR FIVE YEARS,
ALEXIS HAS BEEN TRYING TO CRACK

THIS STICKY MYSTERY.

SHE'S DISCOVERED
A FROG'S TONGUE MUSCLE

IS 10 TIMES SOFTER THAN OURS,

SQUISHY LIKE BRAIN TISSUE,

BUT AS ELASTIC AS A BUNGEE CORD.

AND IT'S COVERED
IN THICK, STICKY SALIVA.

Noel:
THE WAY I LIKE TO IMAGINE IT IS
ACTUALLY A PIECE OF CHEWING GUM

COVERED IN STICKY HONEY.

AND THAT'S BASICALLY
WHAT A FROG TONGUE

AND TOAD TONGUES ARE LIKE.

Narrator:
THIS ELASTIC, HONEY-LIKE SALIVA

IS MADE FROM THE SAME CELLS
FOUND IN OUR MUCUS.

FROG SALIVA IS ABOUT
THE SAME CONSISTENCY.

IT'S WHAT MAKES THE SALIVA
SO STICKY AND GOOEY.

Narrator:
BUT WITH A TONGUE SO STICKY,

WHY DOESN'T ITS MOUTH
STICK SHUT?

FROG SALIVA IS ACTUALLY
A REVERSIBLE ADHESIVE,

SO IT'S ABLE TO CHANGE
HOW STICKY

OR HOW VISCOUS ITS SALIVA IS

BASED ON WHEN IT'S
CONTACTING THE INSECT

OR WHEN IT'S TRYING
TO SWALLOW THE INSECT.

Narrator: TO REVEAL THE SECRET
OF HOW THIS SALIVA CAN SWITCH

BETWEEN STICKY AND UN-STICKY,

ALEXIS FILMS THE TONGUE LASHINGS

WITH A HIGH-SPEED CAMERA.

FIRST, THE ELASTIC TONGUE
ROLLS OUT INTO ACTION.

WHEN THE TONGUE SLAPS
INTO A BUG,

IT LOOKS LIKE THE BUG'S STUCK
WITH FAST-ACTION SUPER GLUE.

BUT WHAT'S ACTUALLY HAPPENING
IS THE TONGUE IS SO FAST,

IT HITS THE BUG WITH A FORCE
12 TIMES GREATER THAN GRAVITY,

AND THE PRESSURE FROM THIS FORCE

CHANGES THE MOLECULAR STRUCTURE
OF THE SALIVA,

TURNING IT FROM ITS NATURAL
THICK AND GOOEY STATE

INTO A RUNNY, WATERY LIQUID.

Noel: IT'S THE FLUID
ACTUALLY BEING SQUISHED

THAT CAUSES THE SALIVA
TO DROP ITS VISCOSITY

FROM HONEY TO WATER.

Narrator: WHEN THE SUPER-FAST
TONGUE MAKES CONTACT,

THE SALIVA BECOMES
50 TIMES THINNER.

IT'S SO WATERY,
IT CAN SEEP INTO ALL THE GROOVES

ON THE INSECT'S SHELL.

A FRACTION OF A SECOND LATER,

AS THE PRESSURE
FROM THE IMPACT FADES,

THE SALIVA GOES BACK TO BEING
THICK AND GLOOPY AGAIN,

EXPANDING IN THE CRACKS,

CREATING A VICE-LIKE GRIP
ON THE BUG.

SO THAT INSECT HAS NO CHANCE
OF GETTING OFF THE TONGUE.

Narrator: SO THE REASON
A FROG'S TONGUE IS SO STICKY

IS BECAUSE IT'S SO FAST,

GUARANTEEING ANY BUG
A STICKY END.

COMING UP...

A BIRD THAT DINES ON BOTULISM,

AND THE SECRET TO THIS SPIDER'S
INCREDIBLY LONG LIFE.

Narrator:
ANIMALS CAN MAKE A MEAL

OUT OF PRETTY MUCH ANYTHING.

BUTTERFLIES DINE ON SALTY TEARS.

DUNG BEETLES --
WELL, YOU KNOW WHAT THEY EAT.

AND VULTURES,
NATURE'S CLEANUP CREW,

HAVE A TASTE FOR ROTTING FLESH.

CONSIDERING THIS BUFFET
OF LETHAL BACTERIA,

HOW ARE VULTURES IMMUNE
TO DISEASE?

[ BIRD SCREECHES ]

[ BIRDS CHIRPING ]

TO FIND OUT, WE'VE COME
TO THE VulPro VULTURE SANCTUARY

IN SOUTH AFRICA.

HERE, CONSERVATIONIST
KERRI WOLTER

TAKES CARE OF MORE THAN
400 RESCUED CAPE VULTURES.

Wolter:
THESE BIRDS ARE JUST INCREDIBLE.

THEY'RE NATURE'S
GARBAGE COLLECTORS.

THEY'RE ABLE TO CONSUME
ANY TYPE OF CARCASS

THAT HAS DIED
OF VARIOUS DISEASES.

Narrator: TO SEE HOW VULTURES
CAN SURVIVE DISEASE-RIDDEN MEAT

THAT WOULD KILL EVERYTHING ELSE,

KERRI HAS OPENED UP
A VULTURE RESTAURANT.

WITH ENTREES TOO TOXIC
FOR HUMANS TO HANDLE,

HER CUSTOMERS AREN'T WORRIED
ABOUT EXPIRATION DATES.

THEY CAN EAT FRESH FOOD,
AND THEY CAN EAT

THE MOST ROTTEN PIECE OF MEAT
THAT IS LYING AROUND.

Narrator:
FROM THE MOMENT AN ANIMAL DIES,

BACTERIA START TO SPREAD
THROUGHOUT THE BODY.

IN JUST A COUPLE OF HOURS

THIS MEAT WOULD BE LETHAL TO US,

BUT VULTURES HAPPILY DIVE IN.

THEIR SECRET --

A CHEMICAL ARSENAL
HIDDEN IN THEIR GUTS.

VULTURES HAVE THE MOST ACIDIC
STOMACH ACIDS OF ANY ANIMAL.

THEIR ACIDITY IS 10 TIMES
WHAT A HUMAN STOMACH WOULD BE.

THEY'RE ABLE TO BREAK DOWN
ANY OF THESE BACTERIA

OR POTENTIAL
INFECTIOUS DISEASES.

Narrator: THE VULTURE'S
STOMACH JUICES ARE MORE ACIDIC

THAN CAR BATTERY ACID --

SO CORROSIVE,
IT DISSOLVES NOT JUST BONES,

BUT METALS LIKE COPPER
AND NICKEL

AND COMPLETELY OBLITERATES
DEADLY DISEASES LIKE RABIES,

CHOLERA, AND EVEN ANTHRAX.

BUT INCREDIBLY, BY THE TIME
THE VULTURE POOPS,

THE REMNANTS ARE TOTALLY
DECONTAMINATED --

ULTRA-FILTERED FECES,
YOU MIGHT SAY.

BUT WHEN YOU HAVE TO GO IN
HEADFIRST TO GET YOUR MEAL,

THINGS CAN GET A LITTLE MESSY
AT THE DINNER TABLE.

THAT'S WHY VULTURES
MAKE A BOLD FASHION CHOICE.

THEY GO BALD.

[ BIRDS CHIRPING ]

WITH NO FEATHERS
ON THEIR HEADS AND NECKS,

THEY DON'T NEED TO WORRY
ABOUT BLOOD AND MEAT

CLOGGING THEIR FEATHERS.

IN JUST TWO HOURS, THE VULTURES
HAVE STRIPPED THE CARCASSES

TO SKIN AND BONES.

EACH BIRD HAS EATEN 4 1/2 POUNDS
OF ROTTEN, STINKING MEAT,

THE EQUIVALENT OF A MAN EATING
170 OUT-OF-DATE, RAW BURGERS

IN ONE SITTING.

BUT PLEASE DON'T
CONSIDER THEM DISGUSTING.

VULTURES ARE LIFESAVERS.

WITHOUT VULTURES
TO ERADICATE THE DEAD,

DANGEROUS BACTERIA
WOULD MULTIPLY IN CARCASSES

AND INFECT OTHER ANIMALS.

Wolter: THESE BIRDS ARE
SO INCREDIBLY IMPORTANT.

THEY ARE ESSENTIAL
FOR OUR ENVIRONMENT.

Narrator: VULTURES TRULY ARE
THE ULTIMATE CLEANUP CREW.

[ BIRD SCREECHES, HOOTS ]

NEXT, A SPIDER'S SECRET
TO A LONG LIFE.

Narrator: SPIDERS.

IF THEY'RE LUCKY,
THE TYPICAL GARDEN VARIETY

LIVES FOR ABOUT A YEAR.

THE BIGGER THEY GET,
THE LONGER THEY TEND TO LIVE,

WITH SOME TARANTULAS
SURVIVING INTO THEIR 20s.

BUT IN AUSTRALIA,
SCIENTISTS HAVE DISCOVERED

AN AMAZING
AND RECLUSIVE ARACHNID

THAT LIVES TWICE AS LONG
AS ANY OTHER SPIDER,

REACHING THE RIPE, OLD AGE
OF 43.

THIS IS THE TINY

AND APPROPRIATELY NAMED
TRAPDOOR SPIDER.

THEY'RE HARD TO SPOT,

AND THEY DON'T GIVE UP
THEIR SECRETS EASILY.

HOW DOES A SPIDER LIVE SO LONG?

THE SECRET TO THIS TIMID
LITTLE CRITTER'S LONG LIFE

IS HIDING BEHIND THIS DOOR.

IT'S THEIR EXTRAORDINARY HOME.

THE TRAPDOOR SPIDER'S BURROW
CAN REACH 12 INCHES LONG

AND ABOUT 2 INCHES WIDE.

THEY DIG IT OUT
WITH SPECIALLY ADAPTED

AND HARDENED MOUTH PARTS,
LIKE DIGGING FANGS.

THEN THE INDUSTRIOUS SPIDERS
WALLPAPER THE CHAMBER

WITH THEIR OWN SILK
TO KEEP IT FROM CAVING IN.

PART OF THE REASON
THESE SPIDERS LIVE SO LONG

IS THEIR SECURE HOME
KEEPS THEM SAFE FROM PREDATORS.

MORE THAN THAT, THESE HOMEBODIES
NEVER LEAVE IT,

NOT EVEN FOR DINNER.

INSTEAD, THEY GET IT DELIVERED.

THEY GRAB MEALS
RIGHT FROM THEIR DOORSTEP,

THANKS TO AN INCREDIBLE
BOOBY TRAP.

THIS AMAZING TRAPDOOR

IS MADE OUT OF SOIL
AND PIECES OF LEAVES

BOUND INTO A LID
WITH SPIDER SILK.

THEY EVEN FASHION A SILK HINGE,

WHICH ENSURES THE DOOR
DOESN'T FLY OFF

WHEN THE SPIDER JUMPS OUT --

HANDY FOR WHEN
YOU GET THE WRONG ORDER.

BUT MEALS AREN'T ALWAYS EASY
TO COME BY.

THE SPIDER CAN WAIT FOR DAYS,
SOMETIMES WEEKS

FEELING FOR THE MOVEMENT
OF A PASSING BUG,

WHICH THE SPIDER DETECTS

WITH SUPER-SENSITIVE HAIRS
ON ITS LEGS.

DURING THIS WAIT, THE SPIDER
DOES SOMETHING INCREDIBLE.

IT POWERS DOWN.

AND HERE STARTS
THE REAL SECRET TO A LONG LIFE.

INSIDE ITS BODY,
THE CONTINUOUS CYCLE

OF CELL DIVISION
AND REPLICATION SLOWS.

EVERY TIME A CELL SPLITS,
IT DAMAGES ITS DNA.

THIS IS ONE OF THE MAIN
CAUSES OF AGING.

SO BY SLOWING DOWN
CELL DIVISION,

A TRAPDOOR SPIDER
IS ABLE TO EXTEND ITS AGE.

BUT THAT'S JUST ONE
OF ITS ANTI-AGING TRICKS.

BY USING UP SO LITTLE ENERGY,

THE SPIDER DOESN'T
NEED MUCH FOOD,

WHICH IS LUCKY, BECAUSE WHEN
FINALLY AN INSECT DOES PASS BY,

THERE'S A GOOD CHANCE
THAT THE SPIDER WILL MISS.

OOPS.

AND AGAIN?

ONLY 10% OF THIS SPIDER'S
AMBUSHES ACTUALLY WORK.

BUT SCIENTISTS HAVE DISCOVERED

THAT THE SPIDER'S
LOW-CALORIE DIET

CAN LEAD TO A LONGER LIFE.

SO IT LOOKS LIKE OUR DOCTORS
HAVE BEEN RIGHT ALL ALONG.

THE SECRET TO A LONG,
HEALTHY LIFE IS EAT WELL

AND GET PLENTY OF REST.
AND ONE MORE THING --

GET ALL YOUR MEALS DELIVERED.
WHO KNEW?
