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 DO POLAR BEARS KEEP WARM?

CAN SPIDERS REALLY FLY?

AND IS YOUR PUG SMARTER
THAN A WOLF?

[ WOLF HOWLS ]

THESE WONDERS AND MORE ON...

CAPTIONS PAID FOR BY
DISCOVERY COMMUNICATIONS

AS RED RIDING HOOD KNOWS,
WOLVES ARE INCREDIBLY CLEVER.

[ WOLF HOWLS ]

THEIR CUNNING COMBINED
WITH BREATHTAKING TEAMWORK

MAKES THEM SUPREME HUNTERS.

WHAT ABOUT DOMESTIC DOGS?

THEY'RE DESCENDED FROM WOLVES
AND HAVE BEEN

SELECTIVELY BRED BY HUMANS
OVER THOUSANDS OF YEARS

SO THAT THEY CAN DO THIS...

AND THIS.

WOW!

DO THEIR SKILLS MEAN OUR DOGS
NOW HAVE MORE SMARTS

THAN THEIR CANINE ANCESTORS?

OR HAS GENERATIONS
OF DOMESTICATION

DRAINED MAN'S BEST BUDDY
OF BRAIN POWER?

[ WOLF HOWLS ]

IN A DARK, DARK WOOD

ON THE OUTSKIRTS
OF VIENNA, AUSTRIA,

LIVES A PACK OF
NORTH AMERICAN GREY WOLVES.

[ SPEAKS FOREIGN LANGUAGE,
SMOOCHES ]

Narrator:
AND ONE LADY HAS KNOWN THEM

SINCE THEY WERE PUPS.

NO.
DESPITE THE RED COAT,

SHE'S NOT
LITTLE RED RIDING HOOD.

SHE IS DR. FRIEDERIKE RANGE
FROM THE WOLF SCIENCE CENTER.

TODAY SHE'S GOING TO PIT THE
BRAIN POWER OF WOLF AGAINST DOG.

FOR TEAM WOLF,
WE HAVE SHIMA AND ARAGORN.

MY, WHAT BIG TEETH THEY HAVE.

REPRESENTING
MAN'S BEST FRIEND --

FRED AND TOTO.

TURN.

FRIEDERIKE WANTS TO TEST

HOW WELL THE DIFFERENT SPECIES
RESPOND TO COMMANDS.

SHE'S BEEN TRAINING BOTH
THE DOGS AND WOLVES FOR YEARS.

STAY.

FIRST OFF FOR TEAM DOG
IS FRED.

STAY.

NOW COME.

CLEVER BOY!

STAY.
STAY.

CAN ARAGORN SHOW THE SAME LEVEL
OF OBEDIENCE AS FRED?

WHY, HE'S QUITE GOOD
AT IT,

BUT AS SOON AS
I PUT DOWN MY HAND,

HE WILL MOVE.

WE HAVE BEEN TRAINING THIS
ANIMAL TO STAY FOR 10 YEARS,

AND THIS IS THE RESULT --
WHAT YOU SAW.

I MEAN, WE CAN'T GET
ANY FURTHER, REALLY.

SINCE FRED AND ARAGORN HAVE BOTH
HAD THE SAME TRAINING

SINCE THEY WERE PUPS,
THIS BASIC TEST OF OBEDIENCE

SEEMS TO GIVE DOMESTIC DOGS
THE EDGE.

NEXT UP IS
A PROBLEM-SOLVING TEST.

FOOD WILL BE PLACED OUT OF REACH
ON THE YELLOW PLANKS.

TO GET IT, OUR CANINE CONTENDERS
NEED TO PULL ON THE ROPES,

BUT THE TRAY ONLY MOVES
IF THE TWO ROPES

ARE PULLED AT THE SAME TIME.

THEY'VE ALL SEEN IT BEFORE,

BUT LET'S SEE IF
THEY REMEMBER HOW IT WORKS.

SO IN ORDER THAT
THEY ARE SUCCESSFUL,

THEY ACTUALLY HAVE TO
WORK TOGETHER.

Narrator: FIRST OUT OF THE GATE
IS ARAGORN.

HE SMELLS THE TREAT AND QUICKLY
WORKS OUT THAT,

TO GET IT,
HE NEEDS TO PULL THE ROPE.

BUT THIS ISN'T A ONE-WOLF JOB.

UM, IT'S NOT A TUG-OF-WAR, GUYS.

OKAY, SO IT'S A FAIL THIS TIME,

BUT LET'S GIVE THEM
A SECOND CHANCE.

♪♪

WAY TO GO.

THE WOLVES HAVE LEARNED
THAT THEY NEED TO COOPERATE

TO GET THE TREAT.

GO AHEAD, GUYS.

YOU'VE EARNED IT.

Range: THIS REALLY NICELY SHOWS
THAT, OKAY,

HE KNOWS THAT HE HAS TO WAIT
UNTIL SHE'S THERE,

AND THEN THEY CAN SOLVE
THE TASK TOGETHER.

Narrator: NOW IT'S TIME FOR
TEAM DOG TO DO THE SAME THING.

TREAT, TREAT, TREAT,
TREAT, TREAT!

Narrator: SURELY, 20,000 YEARS
OF DOMESTICATION

MUST HAVE ENHANCED
FRED AND TOTO'S BRAIN POWER.

THEN AGAIN...MAYBE NOT.

AND ROUND TWO.

OH, NOW YOU'RE JUST
EMBARRASSING YOURSELVES.

THEY FAIL.

Narrator: SO HAS TEAM WOLF
CLAIMED THE CROWN?

WELL, THE TRUTH IS
THEY'RE BOTH CLEVER.

THEY JUST HAVE
DIFFERENT TYPES OF SMARTS.

WOLVES ARE PACK HUNTERS.

THEY NEED TO BE ABLE TO
BRING DOWN A BISON

OR FIGHT OFF A BEAR
THAT'S TWICE THEIR WEIGHT

AND JUST AS FEROCIOUS.

THESE CHALLENGES CAN
ONLY BE SOLVED

THROUGH TEAMWORK
AND COOPERATION.

BUT AFTER THOUSANDS OF YEARS
OF TREATS AND PATS,

DOGS DON'T NEED TO WORK
WITH OTHER DOGS TO SURVIVE.

INSTEAD, THEY NEED
TO WORK WITH US.

FROM SHEEP-HERDING
TO SEARCH AND RESCUE

AND WHATEVER THIS TOUGH GUY
DOES,

DOGS HAVE LEARNED HOW
TO COOPERATE WITH HUMANS

BUT HAVE LOST THE ABILITY
TO COOPERATE WITH EACH OTHER.

[ WOLF HOWLS ]SO WHO IS SMARTER?

I THINK WE'RE GOING TO
HAVE TO CALL IT A TIE.

[ DOG SIGHS ]

[ BIRDS CHIRPING ]

THE ARCTIC -- ONE OF THE COLDEST
PLACES ON EARTH.

TEMPERATURES CAN DROP TO
92 DEGREES BELOW ZERO,

COLD ENOUGH TO FREEZE HUMAN SKIN
IN JUST TWO MINUTES.

IT'S HARD TO IMAGINE
ANYTHING SURVIVING

IN THIS EXTREME CLIMATE,

BUT IT'S EXACTLY HOW
ONE MIGHTY MAMMAL LIKES IT --

THE POLAR BEAR.

THESE HYPERCARNIVORES
CAN GROW UP TO 9 FEET

AND WEIGH 1,300 POUNDS.

THAT'S THE EQUIVALENT
OF FOUR SUMO WRESTLERS.

THEY CAN SNIFF OUT A SEAL
FROM 20 MILES AWAY

AND HIT SPEEDS
OF 25 MILES AN HOUR.

BUT HOW ARE POLAR BEARS
DESIGNED TO SURVIVE

AN EXTREME ARCTIC WINTER?

WE ALL KNOW THESE SUPREME
HUNTERS ARE COVERED

IN A COAT OF FABULOUS FUR,
AND IT'S DOUBLY FABULOUS

BECAUSE THEY'VE GOT
TWO KINDS OF FUR

TO KEEP THEM WARM
IN THIS PUNISHING ENVIRONMENT...

...FIRST, AN OUTER LAYER
MADE UP OF 6-INCH-LONG HAIR

THAT'S BOTH OILY
AND WATER-REPELLENT.

IF WE WENT FOR A DIP
IN THIS OCEAN,

IT'D BE LIGHTS OUT IN MINUTES.

BUT EVEN IN THESE ICY WATERS,
A POLAR BEAR'S OUTER FUR

KEEPS ITS BODY TEMPERATURE
AT A CONSTANT 98.6 DEGREES.

BENEATH THEIR WINTER WETSUIT
IS AN UNDERCOAT

OF MUCH SHORTER, THICKER HAIR
THAT HELPS THEM STAY WARM

BY TRAPPING HEAT
CLOSE TO THE SKIN.

THE SKIN ITSELF
ALSO PLAYS ITS PART

IN KEEPING THESE BEARS
WARM AND TOASTY.

UNDER THAT CREAM-COLORED COAT,

THE POLAR BEAR'S SKIN
IS ACTUALLY BLACK,

WHICH ABSORBS HEAT
FROM THE RAYS OF THE ARCTIC SUN.

THESE SUBZERO SURVIVORS HAVE
ONE FINAL BODY-WARMING WEAPON

IN THEIR IMPRESSIVE ARSENAL --

A 4-1/2-INCH LAYER OF FAT

THAT INSULATES THEM
FROM THE COLD ARCTIC AIR

LIKE A BIG, THICK,
BLUBBERY BLANKET.

WITH ALL THIS HEAT RETENTION
BUILT IN,

A POLAR BEAR'S BIGGEST PROBLEM
ISN'T STAYING WARM

BUT KEEPING COOL.

IN FACT,
THEY LOSE SO LITTLE HEAT

THAT ON A THERMAL-IMAGING
CAMERA,

ONLY THEIR FACE
IS CLEARLY VISIBLE.

YES, POLAR BEARS CAN ACTUALLY
OVERHEAT,

BUT IT MEANS THEY CAN HAVE FUN
TRYING TO KEEP COOL.

ABSOLUTELY FUR-BULOUS.

[ OWL HOOTING ]

COMING UP --
EXTRAORDINARY SOARING SPIDERS,

REMARKABLE RAPTORS,

AND A DEEP-SEA CLEANING SERVICE.

Narrator:
WHETHER BIG FEATHERS...

OR LITTLE FEATHERS...

OR NO FEATHERS...

THESE WINGS BELONG TO SOME OF
THE BEST FLIERS ON THE PLANET,

BUT THERE'S ONE TINY CRITTER
YOU MIGHT NOT EXPECT

TO BE CRASHING
THE PILOT PARTY,

AND THIS ONE'S GOT
EIGHT LEGS AND ZERO WINGS,

AND THEY'RE SUCH HIGH ACHIEVERS

THEY CAN FLY ACROSS
ENTIRE OCEANS.

THAT'S RIGHT --
ALL EIGHT LEGS CAN GO AIRBORNE.

THIS MIGHT SOUND LIKE
A FLIGHT OF FANCY,

BUT THESE SPIDERS AREN'T JUST
BLOWING IN THE WIND.

SCIENTISTS BELIEVE
THEY MAY ACTUALLY BE ABLE

TO PERFORM CONTROLLED FLIGHT

BY USING THEIR SILK
LIKE TINY SPIDER AERONAUTS.

IN THE U.K., DR. ERICA MORLEY
IS RESEARCHING SPIDER FLIGHT,

ABLY ASSISTED BY HER COPILOT

FROM THE LINYPHIIDAE
SPIDER FAMILY.

THAT'S MONEY SPIDERS
TO YOU AND ME.

AND THESE CHAPS
ARE REAL HIGH-FLIERS.

Morley:
YOU MIGHT NOT THINK OF SPIDERS
AS BEING VERY GOOD AT FLYING,

BUT ACTUALLY, THEY CAN GO FOR
HUNDREDS AND HUNDREDS OF MILES,

SO THEY'RE VERY GOOD
AT TRAVELING THROUGH THE AIR.

Narrator: TO GO GLOBAL, SPIDERS
ARE USING THEIR VERY OWN VERSION

OF THE WORLD WIDE WEB,

SHOOTING OUT
LONG STRANDS OF SILK

IN A PROCESS KNOWN AS
BALLOONING.

SO, WHEN A SPIDER
WANTS TO BALLOON,

YOU CAN SEE STICKING OUT
ITS FRONT PAIR OF LEGS.

IT'S JUST ABOUT TO TRY
AND TAKE OFF,

SO IT'S RAISING ITS ABDOMEN,

AND IT'LL BE LETTING OUT SILK
AND THEN TAKE OFF.

Narrator: SPIDERS DON'T ACTUALLY
MAKE SILK BALLOONS.

THEY RELEASE STRANDS OF SILK
SO LIGHT AND THIN --

250 TIMES THINNER
THAN A HUMAN HAIR --

THAT THE STRANDS
CATCH THE WIND LIKE A KITE.

IN A BREEZE, THE AIR CARRIES
THE SILK THREADS,

BUT THEY'RE STRONG ENOUGH
TO CARRY THE SPIDER,

WHO GOES ALONG FOR THE RIDE.

AND USING THE EARTH'S
AIR CURRENTS,

SPIDERS HAVE BEEN FOUND UP TO
2 1/2 MILES UP IN THE AIR

AND 1,000 MILES OUT TO SEA.

SPIDERS USE BALLOONING
TO SEEK FOOD,

AVOID DANGER, AND FIND A MATE,

BUT WHAT HAPPENS
WHEN THERE'S NO WIND?

ARE ALL SPIDERS GROUNDED?

VERY RECENTLY, ERICA HAS
DISCOVERED THAT SPIDERS

COULD BE HARNESSING
ANOTHER POWER TO TAKE OFF --

ELECTRICITY.

THERE'S ALWAYS AN ELECTRIC FIELD
IN THE ENVIRONMENT.

WE ONLY NOTICE IT
WHEN IT'S STRONG,

SO IN THUNDERSTORMS,

CAN CLEARLY SEE
THERE'S ELECTRICITY THERE.

BUT IT'S ACTUALLY THERE
ALL THE TIME.

EVEN ON A SUNNY DAY, THERE
WILL BE A SMALL ELECTRIC FIELD.

Narrator:
AND ERICA BELIEVES THAT

BY USING THEIR SPIDEY SENSES,

ARACHNIDS MIGHT BE HARNESSING

THE EARTH'S NATURAL
ELECTRICAL FIELD

TO CREATE ENOUGH FORCE

TO LAUNCH THEMSELVES
INTO THE AIR WITHOUT WIND.

TO PUT THIS ZAPPY THEORY
TO THE TEST,

ERICA HAS BUILT A UNIQUE CHAMBER
THAT CAN SIMULATE

THIS PLANETARY PHENOMENON
ON A MUCH SMALLER SCALE.

THIS BOX HAS A METAL PLATE
AT THE TOP

AND A METAL PLATE AT THE BOTTOM,

AND WE CAN PRODUCE AN ELECTRIC
FIELD BETWEEN THE TWO PLATES.

IF WE SEE BALLOONING,
WE KNOW THAT IT'S NOT THE WIND.

IT'S THE ELECTRIC FIELD
THAT'S CAUSING THIS BEHAVIOR.

Narrator:
CAN OUR SPIDER GET AIRBORNE

USING THE POWER
OF ELECTRICITY ALONE?

AND THERE IT GOES.

Narrator:
INCREDIBLY, BY HARNESSING

THIS AIRTIGHT CONTAINER'S
ELECTRICAL FIELD,

ERICA IS PROVING

THAT SPIDERS DON'T NEED A BREEZE
TO BLAST OFF,

AND THERE'S A HAIR-RAISING
REASON WHY.

THEY'RE USING TINY, TINY HAIRS
ON THEIR LEGS

TO DETECT THESE ELECTRIC FIELDS.

IF YOU RUB A BALLOON
ON YOUR HEAD

AND THEN HOLD IT UP,
YOUR HAIR WILL STAND ON END.

IT'S A SIMILAR THING

THAT'S HAPPENING
WITH THE SPIDER LEG HAIRS.

Narrator: ONCE THEY'VE DETECTED
AN ELECTRICAL FIELD,

SPIDERS SHOOT SILK STRANDS
OUT OF THEIR BODIES

WHICH HAVE A NEGATIVE
ELECTRICAL CHARGE.

THIS PUSHES AGAINST
A NEGATIVE CHARGE

GENERATED BY THE SURFACE
THEY'RE ON,

CREATING ENOUGH FORCE

TO PROPEL THE SPIDER
INTO THE AIR LIKE A CATAPULT.

ONCE AIRBORNE, THE ELECTRICAL
ACTIVITY IN THE AIR

PULLS THE SPIDER EVEN HIGHER.

OUT IN THE WILD, THE AMOUNT OF
ELECTRICITY IN THE ATMOSPHERE

INCREASES THE HIGHER YOU GO,

AND SPIDERS USE A MIXTURE
OF ELECTRICITY

AND WIND
TO NOT JUST LAUNCH BUT FLY.

SO, DOES ALL THIS MEAN

A TARANTULA COULD BE
SOARING SOMEWHERE OVERHEAD?

NOT TO WORRY.

SCIENTISTS THINK ONLY TINY
SPIDERS ARE CAPABLE OF FLIGHT.

♪♪

COMING UP --
THE ULTIMATE AERIAL ACROBAT

AND A DRIVE-THROUGH WASH
FOR FISH.

Narrator: ONE OF THE LEAST-KNOWN
BIRDS OF PREY, THE GOSHAWK,

HAS BEEN CALLED
THE CHEETAH OF THE SKIES.

AND LIKE ITS BIG-CAT NAMESAKE,
IT'S AMONG THE FASTEST

AND MOST AGILE PREDATORS
ON THE PLANET.

GOSHAWKS CAN WEAVE THROUGH
DENSE FORESTS

PURSUING PREY AT SPEEDS
OF 40 MILES AN HOUR.

BUT WITH SOME ALREADY REMARKABLE
RAPTORS IN THE RUNNING...

THIS IS ELLIE, A 15-YEAR-OLD
NORTHERN GOSHAWK.

AND WITH THE HELP OF
HER WINGMAN AND TRAINER,

LLOYD BUCK,
AND THIS PLASTIC FOREST,

SHE'S HOPING TO SHOW US
WHY SHE'S THE BADDEST BIRD

ON THE BLOCK.

Buck:
THIS IS ELLIE.

SHE'S A BIRD OF PREY THAT HUNTS
OTHER BIRDS AND MAMMALS.

MOSTLY, THEY'RE IN HEAVY FOREST
AND WOODED AREAS --

DENSE COVER --

SO THEY'VE GOT TO BE ABLE
TO CATCH THEIR PREY

IN THAT ENVIRONMENT.

THAT'S NOT EASY.

Narrator: LLOYD IS GOING TO TEST
HOW QUICKLY ELLIE CAN NAVIGATE

AND REACT TO OBSTACLES
OF DIFFERENT SHAPES AND SIZES.

SHE'LL NEED TO WING HER WAY

THROUGH THIS TANGLED FOREST
OF PIPES

AND FINISH BY SQUEEZING
THROUGH A NARROW GAP.

IF YOU HOLD HER UP TO THAT --
LOOK.

THAT'S NARROWER
THAN HER BODY WIDTH AT REST,

SO SHE'S GOT TO DO
SOMETHING SPECIAL

TO FIT THROUGH THERE
AND AT SPEED.

SHE'S NOT ONLY JUST TRYING
TO FLY THROUGH THAT GAP.

SHE'S GOT AN OBJECTIVE,
OR TARGET.

SHE WANTS TO GET THAT LURE.
THAT'S HER PREY.

Narrator:
IN A REAL HUNT SITUATION,

A 4-INCH OPENING WOULD BE ENOUGH

TO PUT OFF EVEN THE MOST
DETERMINED BIRD OF PREY,

BUT WHAT WILL ELLIE MAKE OF IT?

[ ELLIE SQUAWKS ]

RIGHT.
LET'S GIVE HER A GO.

♪♪

GOOD GIRL.

[ ELLIE SQUAWKS ]

Narrator:
FLYING AT OVER 30 MILES AN HOUR,

ELLIE USES
LIGHTNING-FAST REACTIONS

TO ADJUST HER WINGS
AND BODY POSITION.

THEN, WITHIN A FRACTION
OF A SECOND,

SHE CALCULATES A WAY
TO SQUEEZE THROUGH THE GAP.

SHE PUT HER WINGS ABOVE HERSELF.

IT MAKES HER BODY PROFILE LESS
SO SHE CAN FIT THROUGH.

THEY JUST ARE
INCREDIBLE PREDATORS, AMAZING.

GOOD GIRL.

Narrator: LLOYD IS TAKING
ELLIE'S TEST ONE STEP FURTHER.

Buck: WE'RE ADDING ANOTHER
DIMENSION NOW.

WE'VE GOT THIS TUBE,
AND ITS DEPTH SIMULATES

JUST WHAT IT WOULD BE LIKE

IF SHE WAS GOING THROUGH
DENSE COVER.

Narrator:
WHAT'S MORE CHALLENGING --

ELLIE HAS NO IDEA
HOW DEEP THE TUBE IS.

Buck: IT'S ALL ABOUT HER
ANTICIPATING THE TUBE

AND THE HOLE
AS SHE APPROACHES IT.

WITHOUT GETTING THAT RIGHT,
SHE'LL NEVER GET THROUGH.

Narrator: ON APPROACH,

ELLIE WILL HAVE TO CHANGE
THE SHAPE OF HER BODY AND WINGS

AND CALCULATE
HOW LONG THE TUBE IS

AND HOW TO MANEUVER THROUGH IT.

NAILED IT.

Buck: AND THAT'S SOMETHING
THEY HAVE TO DO ALL THE TIME.

YOU KNOW, IF A HARE
OR A RABBIT OR A BIRD

GETS INTO THICK UNDERGROWTH,
THEY HAVE GOT TO CRASH THROUGH

AND MAYBE GO THROUGH A TUNNEL
JUST LIKE THIS.

Narrator: OTHER BIRDS WOULD
LIKELY CRASH INTO THIS HOLE,

BUT NOT ELLIE.

Buck:
LOOK AT WHAT SHE'S DOING.

THE DECISION-MAKING,
THE EVALUATING --

THAT'S WHAT SETS THEM APART.

THAT'S WHAT MAKES THEM
PRETTY MUCH

THE MOST SUCCESSFUL BIRD OF PREY
IN THE WORLD.

[ ELLIE SQUAWKS ]

[ FROG CROAKING ]

Narrator: COMING UP --
THE ULTIMATE ACT OF FAITH

BETWEEN PREDATOR AND PREY.

Narrator:
PREENING, GROOMING, CLEANING --

SOME ANIMALS USE THEIR TRUNKS,

OTHERS THEIR TONGUE.

THAT GUY LIKES
A ROLL IN THE MUD.

THIS ONE PREFERS
A NICE, LONG SOAK.

FISH NEED A SCRUBBING, TOO,

BUT DON'T HAVE THE TOOLS
FOR THE JOB, SO...

FISH, LIKE ANY OTHER ANIMAL,
GET DIRTY.

COVERED IN PARASITES
AND DEAD SKIN CELLS,

EVEN THESE BEAUTIES NEED
A GOOD SCRUB UNDER THE FINS.

AND ONE FISH HAS FOUND
AN INGENIOUS WAY

TO GET THE JOB DONE --

GOAT FISH.

THESE STRIKING STRIPED GUYS
ARE FOUND

IN TEMPERATE WATERS
ACROSS THE PACIFIC.

THEY'RE BOTTOM-FEEDERS

WHO LOVE NOTHING MORE
THAN A GOOD SHRIMP COCKTAIL.

BUT WHEN THE MEAL'S OVER,

AND THE GOAT FISH
IS READY FOR A WASH,

A PECULIAR DEAL IS MADE BETWEEN
THE DINER AND ITS DINNER.

THE GOAT FISH FINDS A SHRIMP,
AND INSTEAD OF ATTACKING,

THE FISH WAITS IN A POSITION
CALLED POSING.

LOOKING GOOD, BUDDY.

THEN THE GOAT FISH
CHANGES COLOR.

THE APTLY NAMED CLEANER SHRIMP
SEES THIS AS A SIGNAL

THAT THE FISH WANTS
TO BE CLEANED,

AND, AMAZINGLY, THE SHRIMP
WAVES ITS ANTENNAE

BACK TO THE FISH
TO AGREE TO THE JOB.

ONCE HE'S SURE
HE'S NOT ON THE MENU,

THE MINI POWER WASHER
GETS TO WORK

EATING UP ALL THE DEAD SKIN
AND PARASITES ON THE GOAT FISH.

IT WILL EVEN SWIM INSIDE
THE GILLS,

SCRUBBING IN ALL THOSE
HARD-TO-REACH PLACES,

BUT IT'S NOT JUST GOAT FISH

THAT'S DONE A DEAL
WITH ITS DINNER.

CLEANER SHRIMP ARE ALSO EMPLOYED
BY OTHER FISHY CLIENTS,

LIKE THIS GROUPER.

I HOPE THIS LITTLE FELLOW
GETS HAZARD PAY.
