CAPTIONS PAID FOR BY
DISCOVERY COMMUNICATIONS

OUT IN THE OPEN,
WITHOUT ANY SEAWEED TO HIDE IN,

THIS PYGMY SEAHORSE
IS RISKING HER LIFE.

AND SHE'S HEADING STRAIGHT
FOR THE JAWS OF A FLOUNDER.

THE FLOUNDER TAKES A BIG BITE
THEN LETS HER GO.

THEN, IN A BIZARRE TURN,

THE SEAHORSE STRETCHES
HERSELF BACK INTO SHAPE

AND CONTINUES ON
LIKE NOTHING HAPPENED.

THIS DELICATE BEAUTY
IS FAR TOUGHER THAN SHE LOOKS,

AND HER SECRET SKELETAL DESIGN

COULD REVOLUTIONIZE PROSTHETICS.[ WHIRRING ]

WHAT MAKES A SEAHORSE
NEARLY INDESTRUCTIBLE?

THERE ARE 47 SPECIES
OF SEAHORSE FOUND

IN SHALLOW WATERS
ALL OVER THE WORLD.

THESE MYSTERIOUS ANIMALS RANGE
FROM A HALF TO 14 INCHES LONG.

ALL ARE ABLE TO CHANGE COLOR
TO BLEND IN

WITH THEIR SURROUNDINGS.

AND EACH HAS A TINY DORSAL FIN
FOR PROPULSION,

WHICH GIVES THEM A TOP SPEED
OF 59...

INCHES PER HOUR.

[ MUSIC SLOWS DOWN ]

♪♪

PETITE FINS MIGHT
MAKE SEAHORSES

THE SLOWEST SWIMMERS
IN THE OCEAN

BUT THEY HAVE ONE
GREAT ADVANTAGE.

THE FIN HARDLY DISTURBS
THE SURROUNDING WATER.

SO SEAHORSES CAN
SLOWLY CREEP UP

TO UNSUSPECTING SMALL
CRUSTACEANS AND PLANKTON.

♪♪

THE DOWNSIDE IS
THEIR SLOW SPEED

ALSO MAKES THEM EASY TO CATCH.

TOP BIOMECHANICAL ENGINEER
PROFESSOR JOANNA McKITTRICK

BELIEVES THIS VULNERABILITY

HAS LED TO THE EVOLUTION
OF SOMETHING QUITE REMARKABLE.

McKittrick:
IF YOU ARE A SLOW SWIMMER

LIKE THEY ARE,
YOU SHOULD HAVE SOME ARMOR.

Narrator: THE SEAHORSE HAS
AN INTERNAL SKELETON.

BUT IT'S ALSO GOT ABOUT
100 ANGULAR

ARMOR-PLATED SEGMENTS COVERING
THE SEAHORSE'S ENTIRE BODY.

AS A RESULT, THE SEAHORSE
HAS THE ONLY TAIL

IN THE ANIMAL KINGDOM
WHOSE CROSS-SECTION IS SQUARE.

NO ONE HAS A SQUARE TAILS
EXCEPT FOR SEAHORSES.

AND SO THAT GOT US THINKING,
WHY ARE THEY SQUARE

INSTEAD OF BEING ROUND?

Narrator:
JOANNA DID SOME INVESTIGATING.

SO WE PUT THE SEAHORSE
INTO A MICRO C.T.

PEOPLE GET C.T. SCANS
ON THEIR OWN BODIES.

AND THEN WE BUILT
AN ARTIFICIAL SEAHORSE TAIL.

♪♪

Narrator: WHEN JOANNA BUILT
A LARGE-SCALE MODEL OF THE TAIL,

SHE UNCOVERED THE SECRET OF THE
SEAHORSE'S INDESTRUCTIBILITY.

IT'S A VERY CLEVER DESIGN.

IF I SQUEEZE IT,
IF I'M A PREDATOR,

YOU CAN SEE
THAT THESE L-SHAPED SEGMENTS

BUCKLE AND DEFORM.

Narrator:
EACH SQUARE BLOCK OF THE TAIL

IS MADE UP OF FOUR
L-SHAPED SEGMENTS.

IN AN ATTACK, THE PLATES
SLIDE OVER EACH OTHER.

BY DOING SO, THEY SOAK UP
THE BITE FORCE

AND PROTECT VITAL PARTS
LIKE THE SPINAL COLUMN.

AND EVEN MORE REMARKABLE,

WHEN THE PREDATOR
RELEASES ITS JAWS,

THE ELASTIC CONNECTIVE TISSUE
SPRINGS THE PLATE

BACK INTO PLACE.

McKittrick: I CAN TWIST IT TO
A HIGH DEGREE AND DROP IT,

AND IT GOES BACK
TO ITS ORIGINAL SHAPE.

Narrator: BUT THAT'S NOT ALL.

SO THIS GLASS ROD
IS GOING TO SHOW

THE PURPOSE
OF THE SEAHORSE'S TAIL.

Narrator: NOT ONLY IS THE ARMOR
INCREDIBLY TOUGH,

THE ABILITY OF EACH
SQUARE SEGMENT

TO OVERLAP THE NEXT MEANS
THE TAIL DOESN'T JUST BEND,

IT CAN GRIP SLIM PLANTS.

YEAH, IT'S CURLED AROUND
180 DEGREES.

SO THE TAIL IS VERY FLEXIBLE.

Narrator:
JOANNA DECIDED TO COMPARE
THE GRIP OF THE SEAHORSE TAIL

WITH A PREHENSILE MONKEY'S TAIL.

A CROSS-SECTION
OF A MONKEY'S TAIL IS CIRCULAR.

THAT MEANS ONLY A SMALL AREA
OF THE ACTUAL TAIL

IS IN CONTACT
WITH WHAT IT'S GRIPPING.

BUT THE SEAHORSE'S SQUARE
TAIL STRUCTURE

IS FAR MORE EFFECTIVE.

YOU CAN SEE THERE'S
A LOT OF SURFACE AREA,

SO IT CAN ADHERE TO THE GRASS
MUCH BETTER THAN THIS ROUND ONE.

SO THERE'S ONLY A LITTLE BIT
OF SURFACE AREA.

SO THAT MAKES IT
A BETTER GRIPPER.

♪♪

Narrator:
THE SEAHORSE'S ARMORED TAIL

HAS INSPIRED
PROFESSOR McKITTRICK

TO USE ITS SQUARE DESIGN

FOR THE NEXT GENERATION
OF MORE FLEXIBLE

AND STRONGER GRIPPING
ROBOTIC ARMS

FOR USE IN SURGERY
AND SEARCH AND RESCUE.

IT'S AN AMAZING DESIGN.

IF YOU WANT TO MAKE
A FLEXIBLE GRIPPER,

ASK THE SEAHORSE.

Narrator: IT SEEMS THESE
EXTRAORDINARY ANIMALS

HAVE BEEN HIDING A SECRET.

IT'S DEFINITELY HIP
TO BE SQUARE.

IF A DOG GETS ITS JAWS
ON A BONE OR A CHEW TOY,

THE INSTINCT FOR MANY
IS TO BURY IT.

WHICH IS CRAZY, BECAUSE IN
THE GROUND, THINGS GET FILTHY

OR NIBBLED BY BUGS.

BUT MANY DOGS JUST CAN'T HELP
BURYING OBJECTS

OR TREATS THEY LOVE.

[ BARKING ]WHY DO DOGS BURY THINGS?

[ WHIMPERING ]

OBSERVING PUPPIES
AND YOUNG DOGS,

SCIENTISTS HAVE NOTICED
SOMETHING REMARKABLE.

SOME WILL TRY TO BURY
THEIR TOYS INDOORS,

AND OTHERS USE THEIR MUZZLE

TO PUSH IMAGINARY DIRT
OVER THEIR TREATS.

THE DOGS' BURYING INSTINCT

INVOLVES AT LEAST
FIVE SEPARATE INSTRUCTIONS.

[ DOG BARKS ]

TAKING THE SPECIAL THING
TO A SAFE PLACE.

CHECK NO ONE IS LOOKING.

DIG A HOLE.

DROPPING THE THING IN.

COVER IT WITH THE MUZZLE.

LIKE ALL INSTINCTS,
THESE COMPLICATED INSTRUCTIONS

ARE ENCODED INTO THE DOG'S DNA.

[ DOG BARKS ]

[ DOG PANTING ]

AND 99 PERCENT OF A DOG'S DNA

COMES FROM THESE GUYS --
GRAY WOLVES.

BECAUSE DESPITE AROUND
40,000 YEARS OF SEPARATE

EVOLUTIONARY DEVELOPMENT,
DOMESTIC DOGS AND GRAY WOLVES

STILL BELONG
TO THE SAME SPECIES.

[ HOWLING ]

FOR WOLVES, HOARDING FOOD
IS VITAL FOR SURVIVAL.

IN THE SNOW, WOLVES ARE ABLE
TO CORNER AND TAKE DOWN A DEER,

A BOAR, EVEN A HALF-TON ELK.

ONCE THE PACK
HAS HAD ITS FILL,

THEY DRAG THE REMAINS
TO A SAFE SPOT.

WITHOUT A FRIDGE,
THE WOLF DIGS A NICE HOLE,

PLACES THE FOOD IN IT,

AND COVERS IT OVER
WITH ITS NOSE,

JUST LIKE DOMESTIC DOGS DO.

THE COLD GROUND KEEPS
THE KILL FRESH FOR WEEKS.

♪♪

DESPITE 40,000 YEARS
OF NOT NEEDING TO DO THIS,

YOUR PET IS POWERLESS
TO RESIST ITS WOLF DNA.

IT JUST YEARNS TO PUT A CHUNK
OF ELK IN THE FREEZER.

SINCE ELK HERDS DON'T FREQUENT
MANY BACKYARDS,

YOU MAY INSTEAD FIND

BURIED AMONG THE PETUNIAS.

THE URGE IS HARD-WIRED
INTO YOUR DOG'S BRAIN,

SO IT'S HARD TO STOP IT.

[ PANTS ]

BUT THERE IS HOPE.

SCIENTISTS HAVE NOTICED
THE MORE MODERN BREEDS OF DOG

LIKE THIS CHIHUAHUA

ARE LESS LIKELY TO CARRY
THE BURYING GENE

THAN ANCIENT BREEDS
LIKE THIS HUSKY.

SO IT'S POSSIBLE
IN ANOTHER 40,000 YEARS,

DOGS WILL HAVE LOST
THE UNNECESSARY INSTINCT TO DIG.

GOOD NEWS -- THERE'S LIGHT
AT THE END OF THE TUNNEL.

[ CROAKING ]

COMING UP -- WHAT MAKES THESE
THE MOST SENSITIVE WHISKERS

ON THE PLANET?

AND CAN THIS TRUNK DETECT ODORS
NO OTHER NOSE CAN?

Narrator: 20 YEARS AGO,

RESEARCHERS TRACKED
A HERD OF ELEPHANTS

MARCHING THROUGH
WAR-TORN ANGOLA.

AT THE TIME, FOR NO APPARENT
REASON, THEY STOPPED,

TURNED LEFT,
AND TOOK A DETOUR.

[ CRACKLING ]

IT WAS LATER DISCOVERED

CHANGED COURSE AROUND
A HIDDEN MINEFIELD.

THAT REMARKABLE BEHAVIOR
GOT SCIENTISTS WONDERING --

CAN ELEPHANTS DETECT BOMBS?

MILITARY RESEARCHER
KIP SCHULTZ HAS COME

TO BELA-BELA, SOUTH AFRICA.

WHAT DO YOU THINK,

HE'S INVESTIGATING REPORTS THAT
ELEPHANTS MIGHT EVEN BE BETTER

DIFFERENT PAINT BUCKETS.

EACH ONE WILL
BE LOADED WITH A PAD.

ONE IT WILL HAVE A PAD IN THERE
WITH A QUANTITY OF TNT

THAT'S PROBABLY
10 MILLIGRAMS OR LESS.

♪♪

Narrator:
10 MILLIGRAMS OF TNT

IT'S LIKE A FEW GRAINS OF SALT.

THIS EXPLOSIVE IS DESIGNED
TO BE ALMOST ODORLESS.

SO IN TODAY'S TEST, A HUMAN
WOULD SMELL AND SEE NOTHING.

Schultz: CHISHURU
DID VERY WELL TODAY.

I DIDN'T SEE ANY MISSES
OF ANY TARGETS THAT WE PUT OUT,

AND WE DIDN'T HAVE
ONE FALSE ALERT.

RESEARCH HAS REVEALED THAT

WHILE A TOP TRAINED DOG
CAN DETECT THE PRESENCE OF TNT

94 PERCENT OF THE TIME,

ELEPHANTS DETECT IT
A STAGGERING

99.7 PERCENT OF THE TIME.

IN OTHER WORDS, ELEPHANTS
ARE 20 TIMES LESS LIKELY

TO MISS A HIDDEN BOMB.

WE DON'T SEE A ROLE
FOR THE ELEPHANT

ACTUALLY IN THE MINEFIELD,

BUT I THINK AS WE START
TO SCRATCH INTO THIS,

WE'LL SEE THAT THERE'S THINGS
THAT WE CAN LEARN

FROM A RESEARCH STANDPOINT
