NO FISH INSPIRES
THE SAME TERROR AS THE SHARK.

YOU'RE IN THE MONSTER'S MOUTH
GETTING THROWN AROUND.

SOMEBODY'S LIKE A RAG DOLL IN ITS
MOUTH GETTING THROWN ALL OVER.

WE'VE GOT SHARKS IN AUSTRALIA
THAT HIT HARD.

THEY DON'T LEAVE ANYTHING.

BUT AT LEAST THESE KILLERS
ARE CONFINED TO THE OCEANS.

OR ARE THEY?

IT SEEMS ONE SPECIES OF SHARK
HAS BEEN TRESPASSING

FROM SALTWATER INTO
MY TERRITORY... FRESHWATER...

OPERATING WHERE PEOPLE
THOUGHT NO DANGER EXISTED.

ALAN!

AS AN ANGLER AND BIOLOGIST, MY AIM
IS TO WORK OUT HOW THIS IS POSSIBLE

AND JUST HOW FAR INLAND THESE SHARKS
WILL BRING THEIR REIGN OF TERROR.

MY MISSION IS TO FIND OUT WHETHER
IT'S SAFE TO GET BACK IN THE WATER,

EVEN IF YOU'RE MILES
FROM THE SEA.

I'M A SPECIALIST IN HUNTING
DOWN GIANT FRESHWATER ANIMALS.

USING A COMBINATION OF LOGIC, LOCAL
INTELLIGENCE, AND INTUITION,

I FACE SHOALS OF PIRANHA IN SOUTH
AMERICA AND MAN-EATING CATFISH IN ASIA.

SHARKS, THOUGH, ARE
A DIFFERENT TARGET ALTOGETHER.

THESE CREATURES
ARE THE STUFF OF LEGEND.

"JAWS," THE ICONIC '70s STORY,

DESCRIBES FEROCIOUS MAN-EATERS
WITH A TASTE FOR HUMAN FLESH.

BUT THE REPORT OF A SHARK OPERATING IN
AN INLAND LAKE IS TRULY TERRIFYING.

TO INVESTIGATE,
I'M HEADING TO AUSTRALIA.

MIDSUMMER ON A BRACKISH LAKE.

THE TEMPERATURE...
OVER 80 DEGREES.

A 23-YEAR-OLD POST-DOCTORATE STUDENT,
BEAU MARTIN, AND HIS FRIEND DAVID

ARE PLANNING A COOLING SWIM
IN MIAMI LAKE.

I'M GONNA FLOG YOU.

I'M GONNA ABSOLUTELY SLAY YOU
IN THIS PLACE.

PUT SOME MONEY
WHERE IT IS.

50 BUCKS?
50 BUCKS, DONE.

YEAH, YOU NEED IT.
YOU NEED THAT FOR THE RACE.

YEAH.

GOING DOWN.

GONNA BEAT YOU.

WHOA.

HEY, KEYS, KEYS, KEYS.
NEED KEYS.

LET'S GO.

SHIRTS OFF... LESS DRAG.
WE'RE GOING. WE'RE GOING.

THEY BEGIN A SWIMMING RACE
ACROSS THE 500-YARD-WIDE LAKE.

DAVE TAKES THE LEAD...

AND REACHES THE SAFETY
OF THE SHORE.

BEAU, HOWEVER,
IS STILL OUT ON THE LAKE.

IN TRYING TO CATCH UP,
HE STRAYS INTO DEEPER WATER.

AAH!

IN AN INSTANT,
HE DISAPPEARS.

DAVE RETURNS TO THE WATER, BUT
THERE'S NO SIGN OF HIS FRIEND.

BEAU'S SUDDEN DISAPPEARANCE HAD ALL
THE HALLMARKS OF A SHARK ATTACK.

BUT FEW COULD IMAGINE
THIS APPARENTLY SAFE BACKWATER

TO BE A HUNTING GROUND
FOR SHARKS.

EVEN HERE, WHERE THERE ARE
THE DEADLIEST SNAKES,

MASSIVE CROCS, THE MOST POISONOUS
SPIDERS, THIS INCIDENT RANG ALARM BELLS.

WE JUST DON'T EXPECT TO BE
ATTACKED BY A SHARK

ON AN INLAND LAKE IN AN URBANIZED
AREA LIKE THE GOLD COAST.

IN AUSTRALIA, THERE ARE
THREE SPECIES OF SHARK

COMMONLY RESPONSIBLE FOR ATTACKS ON
PEOPLE... THE GREAT WHITE, THE TIGER SHARK,

AND THE BULL SHARK.

AUSTRALIANS KNOW VIC HISLOP
AS THE SHARK MAN.

LIKE QUINT FROM "JAWS,"

HISLOP HAS FOUGHT A SERIES
OF BATTLES WITH SHARKS,

INCLUDING
THIS 2 1/2-TON GREAT WHITE.

WE'VE GOT SHARKS IN AUSTRALIA
THAT HIT AND HIT HARD.

THEY DON'T LEAVE ANYTHING.

THEY'RE SO GOOD AT WHAT THEY DO, THEY PULL
SOMEBODY UNDER, YOU DON'T SEE ANY MORE.

SOMEONE'S GOT TO BE LOOKING AT
THAT EXACT SPOT TO SEE IT HAPPEN.

THE GREAT WHITE IS A NOTORIOUS MAN-EATER,
BUT SOME EXPERTS THINK THE BULL SHARK

IS A FAR MORE DEADLY
THREAT ALTOGETHER.

IT'S A VERY ROBUST ANIMAL,
VERY ROUGH AND TOUGH.

BECAUSE OF THE STRUCTURE
OF ITS TEETH,

IT CAN'T JUST BITE
THROUGH A BIG CHUNK OF MEAT.

IT HAS TO BITE AND START SHAKING
LIKE CRAZY.

AND, OF COURSE, SOMEBODY'S LIKE A RAG DOLL
IN ITS MOUTH GETTING THROWN ALL OVER,

AND THAT IMMEDIATELY ALSO INSTIGATES
ALL SORTS OF FEAR REACTIONS.

YOU KNOW, YOU'RE IN THE MONSTER'S
MOUTH GETTING THROWN AROUND.

STOCKY IN SHAPE,
SAVAGE IN CHARACTER,

THE BULL SHARK IS BUILT LIKE A STREET
FIGHTER, WITH A LEVEL OF RAGING AGGRESSION

THAT GIVES IT ITS NAME.

POUND FOR POUND, IT'S TOP
OF THE LEAGUE OF MAN-EATERS.

STATISTICALLY,
A BULL SHARK'S ATTACK

IS MORE LIKELY TO RESULT
IN DEATH THAN A GREAT WHITE'S.

AND THE AUTHORITIES BELIEVE
THAT IT'S A BULL SHARK

THAT KILLED BEAU MARTIN
IN THIS CANAL SYSTEM.

THIS COMPLEX OF WATERWAYS WAS
BUILT DURING THE '70s AND '80s

AND IS BIGGER THAN VENICE, ITALY... 160
MILES OF CANALS AND OVER 30 LAKES.

THIS IS AN AREA WITH
JUST THOUSANDS OF APARTMENTS,

HOUSES RIGHT DOWN
ON THE WATERFRONT.

AND MOST OF THE PEOPLE HERE
JUST THINK OF THESE CANALS

AS A PERFECTLY SAFE PLACE
TO SWIM.

WHAT PUZZLES ME IS HOW ANY SHARK
COULD HAVE MADE ITS WAY HERE,

SO FAR FROM WHERE WE EXPECT TO FIND IT...
THE OPEN OCEAN.

TO WORK THAT OUT, I'M HEADING
60 MILES SOUTH TO THE COAST.

THERE WERE 15 SHARK ATTACKS
IN AUSTRALIA IN 2008,

BUT THERE'S ONE, WELL-REPORTED IN THE
PRESS, THAT IS CENTRAL TO MY INVESTIGATION.

16-YEAR-OLD BROCK CURTIS-MATHEW IS SETTING
OFF WITH HIS FRIEND PETER EDMONDS

FOR SOME
EARLY-MORNING BODYBOARDING.

WE GOT THERE MAYBE
A QUARTER TO 8:00, 8:00-ISH.

THEY'VE CHOSEN A LOCATION NEXT TO
THE MOUTH OF THE RICHMOND RIVER.

THIS IS A POPULAR SURFING SPOT,
OFTEN USED BY THESE CLOSE FRIENDS.

BUT THIS MORNING, AFTER SEVERAL
DAYS OF HEAVY RAIN,

THEY HAVE THE BEACH
TO THEMSELVES.

WE WERE MAYBE LIKE HALFWAY TO WHERE
WE WERE GONNA GO IN THE WATER.

I TURNED AROUND AND CAME
BACK IN, AND HE KEPT GOING.

WHILE BROCK COVERS THEIR POSSESSIONS
IN CASE OF MORE RAIN, PETER HEADS OUT.

HE'S AROUND 35 YARDS
FROM THE SURF LINE.

BUT AS BROCK GOES TO REJOIN HIS
FRIEND, HE GLIMPSES A DARK SHAPE.

I SAW THIS BIG, ROUND,
WEIRD, CIRCLE THING.

WHAT BROCK HAD SEEN
WAS A SHARK.

HE HAS NO IDEA IT IS
ATTACKING HIS FRIEND.

ALL HE CAN SEE FROM 25 YARDS
AWAY IS SOME SPLASHING.

I WAS JUST THINKING,
"OH, WHAT'S HE DOING?

SOMETHING'S...
SOMETHING'S NOT RIGHT."

BROCK APPROACHES
AS QUICKLY AS HE CAN.

WHEN I GOT UP, LIKE, REALLY
CLOSE, I COULDN'T SEE ANY BLOOD.

AND THEN, LIKE, ONCE I GRABBED HIM
AND STUFF, I NOTICED HIS LEG.

RISKING HIS OWN LIFE, BROCK CARRIES HIS
NOW UNCONSCIOUS FRIEND TOWARD SHORE.

HE HAD TAKEN
A FIRST-AID COURSE AT SCHOOL.

THERE WAS A SLIGHT PULSE WHEN I FIRST
CHECKED IT, LIKE A BEAT... BEAT... BEAT.

COME ON, PETE!

IN A STATE OF SHOCK, HE CALLS
THE EMERGENCY SERVICES.

Emergency service.

PLEASE,
HE'S GONNA DIE.

I JUST SAID, "CAN YOU
COME DOWN HERE QUICKLY?"

MY FRIEND'S BEEN ATTACKED
BY A SHARK."

FROM THE SHAPE AND THE SIZE
OF THE WOUND TO PETER'S THIGH,

THE ATTACKER APPEARS
TO BE A BULL SHARK...

SOME 9 FEET LONG.

AFTER THE ATTACK, LIFEGUARD STEPHEN LEAHY
WAS ONE OF THE FIRST ON THE SCENE.

IT WAS OBVIOUS THAT IT WAS
HIGH-IMPACT, IT WAS HARD-HITTING,

AND THERE WAS JUST A LARGE AMOUNT OF
FLESH REMOVED FROM HIS UPPER THIGH.

LEAHY HAS WORKED TO SAVE LIVES ON
THESE BEACHES FOR OVER 15 YEARS.

BUT IN THIS CASE, TRAGICALLY,
PETER HAD LOST TOO MUCH BLOOD.

THERE WAS
JUST ABSOLUTELY NOTHING

THAT WE WERE GOING TO DO
THAT WOULD SAVE THIS BOY'S LIFE.

DR. VIC PEDDEMORS IS THE FIRST
PERSON MEDICAL TEAMS TURN TO

WHEN THEY BELIEVE
THERE'S BEEN A SHARK ATTACK.

IT'S ESTIMATED THAT A SHARK BITE APPLIES
A FORCE OF OVER 4 TONS PER SQUARE INCH.

THE MOST IMPORTANT THING FOR A
SHARK IS TO GET THAT LOWER JAW IN

BECAUSE THOSE ARE THE HOOKING
TEETH THAT SORT OF LATCHES IN.

SO, ONCE IT'S GOT ITS LOWER JAW
IN, THE UPPER JAW CAN CLAMP DOWN.

IF THAT LOWER JAW HAS GOT IN
PROPERLY, IT ONLY NEEDS ONE BITE,

AND IT'LL TAKE THE MUSCLE
STRAIGHT OFF.

BECAUSE OF THE SITE
OF THIS INCIDENT,

THE LIFEGUARD ALREADY HAD THIS
ATTACKER'S IDENTITY IN MIND.

KNOWING THAT THE ATTACK'S
HAPPENED JUST HERE,

WE ALWAYS HAD,
IN THE BACK OF OUR MIND,

THAT THIS WAS GOING TO BE
A BULL SHARK INCIDENT.

IT'S LIKELY THAT THE SHARK HAD CONFUSED
PETER FOR ITS COMMON PREY, A LARGE FISH,

PERHAPS EVEN ANOTHER SHARK.

NOTHING CAN EVER COMPENSATE A FAMILY
OR FRIENDS FOR SUCH A CRUEL LOSS.

BUT IF THERE IS ANYTHING TO BE
SALVAGED FROM THIS TERRIBLE EPISODE,

IT MIGHT BE IN IDENTIFYING THE WARNING
SIGNALS THAT ACCOMPANY A BULL SHARK ATTACK.

BULL SHARKS HAVE BEEN OBSERVED CONGREGATING
AROUND RIVER MOUTHS AFTER HEAVY RAIN,

ATTRACTED BY THE SUPPLY OF FRESHWATER
FISH BEING WASHED OUT TO SEA.

WE KNOW THAT BULL SHARKS WILL
ALWAYS HANG AROUND THE RIVER MOUTH

AFTER PERIODS OF HEAVY RAIN AND
WHEN THERE ARE LOTS OF FISH AROUND.

THE BEACH WHERE THE ATTACK
OCCURRED IS ONLY 60 METERS AWAY

FROM THE ENTRANCE
OF THAT RIVER MOUTH.

THE BULL SHARK THAT KILLED PETER EDMONDS
HAD BEEN ATTRACTED TO THIS SHORELINE

BECAUSE OF ITS PROXIMITY
TO FRESHWATER.

WE'RE WELL AND TRULY AWARE THAT THERE'S
JUST SO MUCH FOR THE BULL SHARK TO LIVE ON

IN OUR FRESHWATER SYSTEMS, AND THAT'S PART
OF THE UNIQUENESS OF THE BULL SHARK...

CAN EASILY COPE IN SALTWATER
AND IN OUR OCEANS,

BUT IT'S JUST AS COMFORTABLE
IN OUR RIVER SYSTEMS.

PERHAPS THIS KNOWLEDGE MIGHT
PREVENT OTHERS BEING CAUGHT,

LIKE PETER, IN THE WRONG PLACE
AT THE WRONG TIME.

AS A BIOLOGIST, I WANT TO BETTER UNDERSTAND
THE PHYSIOLOGY AND PARTICULAR AFFINITY

BULL SHARKS HAVE
FOR FRESHWATER.

I NEED TO CATCH ONE.

I MUST HAVE FISHED LITERALLY THOUSANDS
OF DESTINATIONS ALL OVER THE WORLD,

BUT THIS TIME,
I THINK I'M OUT OF MY DEPTH.

I'VE NEVER TRIED TO CATCH ANY KIND
OF SHARK, LET ALONE A BULL SHARK.

100 MILES NORTH OF WHERE PETER
WAS KILLED, IN SIGHT OF LAND,

I JOIN A FISHING CHARTER BOAT
OUT AFTER SHARKS.

WITH FOUR RODS SET, I KNOW
I'M IN WITH A GOOD CHANCE.

OH, YEAH.

RIGHT. THERE WE GO.

THERE WE GO.
THAT IS A BULL SHARK.

HAMMERED QUITE BIG MULLETS, COUPLE-OF-POUND
MULLETS, AND JUST TOOK OFF.

I THINK WE'RE READY TO BRING IT IN
THE BACK OF THE BOAT, ACTUALLY.

OKAY.

THIS ONE'S
NONE TOO HAPPY TO SEE ME.

BUT AFTER THE HOOK'S OUT,
IT BECOMES EASIER TO HANDLE.

IT'S 4 1/2 FEET LONG, AROUND 1/3
OF THE LENGTH THEY CAN REACH.

BOAT'S ROLLING AROUND
A LITTLE BIT AT THE MOMENT,

SIDE ON TO THE TIDE
AND ROLLING A LITTLE BIT.

SO WITH SOMETHING LIKE THIS MOUTHFUL
OF TEETH, GOT TO BE A WEE BIT CAREFUL.

THE TEETH ARE PARTIALLY
OBSCURED BY THICK GUMS,

BUT THE TIPS ARE
AS SHARP AS SCALPELS.

THAT'S GOOD TO ACTUALLY SEE
ONE OF THESE ANIMALS CLOSE UP,

GET MY HANDS ON ONE...
THAT'S WHAT I WANTED.

BUT WHAT SETS THIS SPECIES OF SHARK
APART IS ITS EXTRAORDINARY ABILITY

TO OPERATE IN BOTH SALTY
AND FRESH WATER.

THE BULL SHARK IS THE ONLY SPECIES
OF SHARK THAT CAN DO THIS.

SOME SCIENTISTS SPECULATE THAT THE BULL
SHARK IS CAPITALIZING ON THIS ADAPTATION

TO DOMINATE
NEW FEEDING GROUNDS INLAND.

THE BULL SHARK IS UNIQUE BECAUSE IT'S
ACTUALLY MUCH MORE CAPABLE THAN OTHER SHARKS

IN REGULATING THE AMOUNT OF SALTS
AND UREA IN ITS BODY TISSUES.

BULL SHARKS CONSTANTLY TEST
THE SALT CONTENT OF THE WATER

WITH TINY SENSORS MOUNTED
ALL OVER THE BODY,

SIMILAR TO THE WAY
WE USE OUR TASTE BUDS.

THEN, A SPECIAL ORGAN, THE RECTAL
GLAND, ACTS LIKE AN ON/OFF VALVE,

RELEASING OR RETAINING SALT
AS REQUIRED.

IT'S REALLY INCREDIBLE HOW
CAPABLE THEY ARE AT DOING THAT.

BUT IT'S OBVIOUSLY,
ENERGETICALLY, VERY COSTLY,

AND THAT'S WHY WE TEND TO FIND THE BIGGER
ANIMALS CAPABLE OF CHANGING VERY QUICKLY,

WHEREAS THE SMALLER ANIMALS

TEND TO STAY WITHIN A RELATIVELY
NARROW BAND OF SALINITY.

THIS AMAZING ADAPTATION
GIVES THE BULL SHARK

A DEADLY ACCESS-ALL-AREAS FREEDOM
TO ROAM, BRINGING ITS VIOLENCE

TO OUR ONCE-PEACEFUL INLAND WATERS...
A PREDATOR THAT CAN OPERATE

IN RIVERS AND ADJOINING LAKES
ALL AROUND THE WORLD,

RESPONSIBLE FOR FATAL ATTACKS
FROM AUSTRALIA TO SOUTH AFRICA,

FROM FLORIDA TO NEW JERSEY.

HERE, IN 1916, FOUR PEOPLE WERE
KILLED AND ONE WAS SEVERELY MUTILATED

IN A 10-DAY SPREE OF ATTACKS.

THIS PROVIDED THE INSPIRATION FOR THE
MOST FAMOUS SHARK STORY OF ALL, "JAWS."

BUT WHAT IS SO TERRIFYING
IS THAT TWO OF THESE DEATHS

OCCURRED 15 MILES UP AN ESTUARY...
AT MATAWAN CREEK...

IN A PLACE THAT EVERYONE
THOUGHT WAS SAFE.

MAN-EATERS ARE SUPPOSED TO BE FOUND IN UNTAMED
PLACES, BUT THIS UNSTOPPABLE PREDATOR

SEEMS TO BE BRINGING ITS SAVAGERY INTO
THE VERY HEART OF OUR CIVILIZED WORLD.

AAH!

IS THERE NOTHING IN PLACE TO
STOP THESE DEADLY PREDATORS?

I'M HERE TO MEET TONY HAM.

G'DAY, JEREMY.
HOW YOU GOING?

HE MANAGES THE SHARK CONTROL PROGRAM
ON THE GOLD COAST IN AUSTRALIA.

GOT THE BAIT ON BOARD.

WE'RE PLANNING TO MAKE AN INSPECTION OF
THE SHARK NETS JUST OFF THE MAIN BEACH.

THIS SECTION OF THE BEACH IS CALLED MAIN
BEACH ON THE OTHER SIDE OF THE SPIT.

THAT'S A FAIRLY HEAVILY
POPULATED BEACH.

IN SUMMER, YOU'D HAVE ANYWHERE
UPWARD OF 50,000, 60,000 PEOPLE

BETWEEN HERE AND SURFERS PARADISE,
AND THEN, FROM SURFERS DOWN FURTHER,

PROBABLY DOUBLE
THAT NUMBER.

IT'S A BIG BEACH JUST RUNNING
UP WITH SORT OF ALL THE HOTELS

AND SOME OF THE TOURIST
AMENITIES BEHIND THAT.

EXACTLY, BUT BRANCHING OFF HERE ARE A
NUMBER OF CANAL ESTATES AND LARGE LAKES.

AND WHAT'S HAPPENED IS IT'S BASICALLY
EXTENDED THE RIVER HABITAT.

AND SO WE HAVE BULL SHARKS HERE
PRETTY CONSTANTLY.

RIGHT UP INLAND?

YEAH, SO BULL SHARKS WILL
ACTUALLY LIVE ALL THE WAY UP

AND INCLUDING INTO FRESHWATER
REACHES OF SOME RIVERS.

SO THEY'RE DEFINITELY
IN THERE,

AND WHEN YOU GET IN THE WATER,
IF YOU GET IN THE WATER,

YOU COULD ONLY BE JUST A MATTER OF
YARDS AWAY FROM ONE, I SUPPOSE.

LITERALLY, FEET, AND YOU
WOULDN'T KNOW THEY WERE THERE

UNLESS, YOU KNOW, YOU ACTUALLY
SEE IT OR IT BUMPS INTO YOU

OR ACTUALLY DOES HAVE
A BITE AT YOU.

AROUND THE SPIT, AT ABOUT 500 YARDS OFF
THE BEACH, THE SWELL HAS PICKED UP.

THIS SHARK NET IS PRETTY MUCH
THE ONLY LINE OF DEFENSE

ALONG A 2 1/2-MILE-LONG BEACH.

THE IDEA IS TO REMOVE SHARKS
THAT COME IN CLOSE TO THE SHORE.

BUT LOOKING AT IT, I CAN SEE
NO REASON WHY BULL SHARKS

WOULDN'T EASILY GO UNDER IT
OR AROUND IT

AND THEN HEAD ON, RELENTLESSLY,
INTO THE CANALS.

AFTER ALL, THE NET IS ONLY 200
YARDS LONG AND JUST 20 FEET HIGH.

SOME THINK THAT THESE MEASURES ARE, IN
FACT, LITERALLY WORSE THAN USELESS.

SHARK NETS IN AUSTRALIA ARE A FALSE
SENSE OF SECURITY FOR TOURISM.

THEY KILL EVERYTHING WE LOVE
OUT THERE.

THEY KILL DOLPHINS,
TURTLES, DUGONG.

BUT MORE IMPORTANT, THE BIG SHARKS
HAVE LEARNED TO FEED OFF THOSE NETS.

THEY'RE NOW A FEEDING GROUND.

COST MILLIONS
OF TAXPAYERS' DOLLARS

FOR A WASTE OF TIME,
JUST A FALSE SENSE OF SECURITY.

IT'S A JOKE.

IF HISLOP IS CORRECT, BULL SHARKS
ARE BEING LURED TOWARDS THE SHORE

AND THEN INLAND
INTO THE CANALS AND LAKES.

AND BECAUSE, INEVITABLY, THEY'LL
MEET MORE PEOPLE INLAND,

THIS SPECIES HAS TO BE
A FAR GREATER THREAT

THAN OTHER MAN-EATING SHARKS
WHICH REMAIN OUT AT SEA.

ON MIAMI LAKE, THE DAY AFTER
BEAU MARTIN'S DISAPPEARANCE,

THE SEARCH BEGINS,
LED BY BEAU'S FATHER.

EXHAUSTIVELY, HE COMBS
THE PERIMETER OF THE LAKE.

FOR TWO DAYS,
THERE IS NO SIGN OF BEAU.

ON THE MORNING OF THE THIRD DAY, AFTER
THE POLICE HAVE GIVEN UP THE HUNT,

HE BEGINS TO SEARCH
FROM HIS KAYAK.

HE HAPPENS UPON THE BODY OF HIS SON,
PART IN AND PART OUT OF THE WATER.

THE ONLY REASON HIS BODY HAD SURFACED...
THE GASES RESULTING FROM DECOMPOSITION,

CAUSING HIS BODY TO INFLATE.

THE AUTOPSY REVEALED THAT BEAU HAD BEEN
STRUCK THREE TIMES... BY A BULL SHARK...

ONE DEVASTATING BITE ON HIS
LEFT THIGH PROVING FATAL.

THIS PREDATOR HAD SLIPPED
WITH EASE

FROM THE SEA INTO THE BRACKISH
WATER OF MIAMI LAKE.

ONCE INSIDE, IT HAD BEEN FREE
TO GO ABOUT ITS BUSINESS UNSEEN

UNTIL THE KILLING OF BEAU MARTIN
REVEALED ITS DEADLY PRESENCE.

BUT JUST HOW MUCH FURTHER
INLAND INTO FRESHWATER

ARE THESE PREDATORS
CAPABLE OF GOING?

80 MILES INLAND FROM THE OCEAN,
TRAINER ALAN TREADWELL IS TAKING

HIS FINEST TROTTING HORSE, GLEN-BURNS
ARM, FOR EXERCISE IN THE RIVER.

I'D SWUM THERE FOR EIGHT,
NINE YEARS, NEVER A PROBLEM.

IT'S A VERY POPULAR PICNIC SPOT.

THIS PART OF THE RIVER
IS A SECLUDED OASIS,

POPULAR WITH FAMILIES
AS A SWIMMING HOLE.

BUT ON THIS DAY, TREADWELL HAS THE RIVER
TO HIMSELF FOR HIS TRAINING PROGRAM.

HE WANTS TO BUILD UP HIS HORSE'S MUSCLE
STRENGTH WITHOUT STRAINING ITS LEGS.

GLEN-BURNS ARM, A 6-YEAR-OLD
GELDING WEIGHING 1,000 POUNDS,

HAS WON 7 TIMES
OVER A 3-YEAR CAREER.

WITH THE HELP OF HIS
STABLE HAND, ALICE HOLDEN,

TREADWELL TIES A HALF-INCH ROPE
TO THE HORSE'S HALTER.

WITH IT, HE CAN CONTROL
THE HORSE FROM THE BRIDGE.

AS FAR AS TREADWELL CAN SEE
FROM 20 FEET UP ON THE BRIDGE,

EVERYTHING APPEARS
TO BE GOING TO PLAN.

THE HORSE WAS SWIMMING.
I HAD CONTROL OF THE HORSE.

BUT SUDDENLY
SOMETHING STARTLES IT.

THE HORSE LOOKS
LIKE IT'S GONNA DROWN.

THEN, ALL OF A SUDDEN, I SAW SOMETHING
HANGING OFF THE BACK OF HIM.

ALAN!

AS THE HORSE ROLLED OVER,
THE COLOR LIGHTENED,

AND IT WENT TO A WHITE
UNDERNEATH, WHATEVER IT WAS.

WHATEVER THIS CREATURE IS, IT
HAS THE FORCE TO HOLD ON TO

AND THE POWER TO SUBMERGE
A 1,000-POUND HORSE.

THE HORSE IS IN TROUBLE.
WE HAD A PROBLEM.

I'VE GOT TO GET THIS HORSE
OUT OF THERE.

WHATEVER'S WRONG, IF I CAN GET HIM
OUT OF THE WATER, I CAN CONTROL IT.

HE WON'T DROWN.

IF WE HADN'T HAVE GOTTEN HIM OUT, I
DON'T BELIEVE HE WOULD HAVE SURVIVED.

TRAINER ALAN TREADWELL WAS ABLE
TO PULL HIS HORSE TO SAFETY.

IF THE VICTIM HAD BEEN A HUMAN,
1/5 OF THE SIZE OF HIS HORSE,

THERE WOULD BE NO HOPE
OF SURVIVING THE ATTACK.

THE HORSE, GLEN-BURNS ARM, WAS
TREATED BY A VETERINARY SURGEON...

WHO PHOTOGRAPHED THE WOUND.

I WANT TO MEET UP
WITH ALAN TREADWELL

TO FIND OUT IF THIS ATTACK CAN
BE ATTRIBUTED TO A BULL SHARK.

HELLO, ALAN.

G'DAY. HOW ARE YOU?
I'M WELL, THANKS.

THIS IS THE BOY, IS HE?
YEAH, THIS IS HIM.

CAN I SAY HELLO?
SAY HELLO.

HEY.

SO HE'S NOT JUST
AN ORDINARY HORSE, IS HE?

HE'S A BIT OF AN ATHLETE. BIT OF AN
ATHLETE... YEAH, HE HAS BEEN. OR USED TO BE.

YEAH.
YEAH.

CAN WE SEE THE WOUND
AT ALL?

CAN YOU SHOW ME
WHERE IT WAS?

YEAH, I CAN DO.

IT'S HEALED PRETTY WELL.

YEAH.

THAT'S WHERE IT WAS,
ON THE FLAT THERE.

RIGHT, SO, LOOKING AT HIM NOW, YOU
WOULDN'T... HE LOOKS FINE. HE LOOKS FINE.

BUT, I MEAN, DID HE RECOVER FULLY, OR...
NO, I DON'T THINK SO.

ACTUALLY, HE SWELLS UP IN THE
FETLOCK AFTER A HARD RUN... RIGHT.

WHICH VIRTUALLY MAKES IT
IMPOSSIBLE TO RACE HIM.

SO, IN EFFECT, THIS ACTUALLY
FINISHED HIS CAREER.

IT HAS DONE, YES.

IT STILL SEEMS TO BE A BIT
AWKWARD IN THAT ONE BACK LEG.

I DON'T KNOW WHAT HAPPENED
TO IT. IT'S IMPOSSIBLE TO SAY.

SO, POSSIBLY, THERE'S SOME SORT OF, YOU
KNOW, DEEP MUSCLE DAMAGE, SOMETHING.

YEAH, IT COULD BE.
THAT'S EXACTLY RIGHT, YEAH.

ALTHOUGH THERE HAD BEEN
NO REPORTS OF SHARKS

THIS HIGH
UP THE BRISBANE RIVER BEFORE,

ALAN TREADWELL BELIEVES
THAT WHAT HE SAW WAS A SHARK.

YET HE ONLY GLIMPSED THE WHITE
SHAPE FOR A FRACTION OF A SECOND.

I WANT TO TAKE A LOGICAL APPROACH TO
DISCOVER EXACTLY WHAT HAPPENED HERE.

MY FIRST STRATEGY
IS TO MEASURE THE SALT CONTENT

AT THIS STRETCH
OF THE BRISBANE RIVER.

THE WATER'S SALTINESS LESSENS
THE FURTHER UPRIVER YOU GO.

I'VE TAKEN A READING OF SEAWATER
WITH THIS MACHINE,

AND THE READING I GET
IS ABOUT 17.

DOWN THE OTHER END OF THE SCALE, ANYTHING
LESS THAN ABOUT 1 IS FRESHWATER,

SO THE FACT THAT I'VE JUST GOT A READING
OF LESS THAN .5... THIS IS FRESHWATER.

I KNOW BULL SHARKS
CAN GET INTO FRESHWATER.

EVERYTHING POINTS TO THIS BEING A
SHARK ATTACK... EXCEPT FOR ONE THING.

THERE'S A GOOD REASON
WHY I DON'T THINK

THEY COULD BE RESPONSIBLE
FOR THIS PARTICULAR INCIDENT.

LOOK AT THIS... JUST 5 MILES DOWN
THE RIVER IS THIS MAN-MADE BARRIER

THAT JUST GOES
RIGHT ACROSS THE RIVER.

MOUNT CROSBY WEIR IS A DAM THAT HAS
BEEN IN PLACE FOR OVER A HUNDRED YEARS.

THE DIFFERENCE IN HEIGHT BETWEEN
THE WATER ON THE OCEAN SIDE

AND THE UPRIVER SIDE
IS 12 FEET.

NOW, I CAN UNDERSTAND HOW SOMETHING MIGHT
POSSIBLY GET UP FROM THE SEA TO HERE,

BUT HOW'S IT GONNA GET
OVER THAT?

SO, WHAT ELSE COULD IT BE?

I THINK THERE MIGHT BE A CLUE IN
SOMETHING ALAN TREADWELL TOLD ME.

ALTHOUGH ON THE SURFACE, THE WOUND
TO GLEN-BURNS ARM HAS HEALED,

UNDERNEATH THE SKIN, THERE IS
SUCH PROFOUND MUSCLE DAMAGE

THAT HE CAN NO LONGER RACE.

THAT IS EXACTLY THE CASE WITH ATTACKS
MADE BY ANOTHER ANIMAL ENTIRELY...

THE SALTWATER CROCODILE.

WHEN A CROCODILE BITES ITS VICTIM,
IT DEPOSITS BACTERIA IN THE WOUND

THAT CAUSE
LONG-TERM MUSCLE DAMAGE.

THE MOST DISTINCTIVE THING ABOUT A
SALTWATER CROC IS THAT BIG, GNARLY HEAD

WITH THOSE BIG, ACTUALLY BLUNT
BUT LONG, PENETRATING TEETH.

SALTWATER CROCODILES WILL LIVE

IN FRESHWATER, SALTWATER,
BRACKISH WATER, MINERAL WATER.

THEY DON'T CARE.

ONCE A CROCODILE REACHES 13, 14 FEET,
AND UP, YOU'RE DEALING WITH AN ANIMAL

THAT CAN TAKE DOWN
A ONE-TON WATER BUFFALO.

IT SEEMS MORE LIKELY THAT THE CREATURE
WHICH ATTACKED GLEN-BURNS ARM

IS NOT A SHARK BUT A CROCODILE.

WHAT THEY PREFER
IS DEEP, DARK, MURKY WATER

BECAUSE THEY ARE
THE MASTERS OF CAMOUFLAGE.

THAT'S HOW THEY GET THEIR PREY.

THEY WILL LAUNCH FROM AN INVISIBLE
POSITION UP OUT OF THE WATER,

GRAB WHATEVER IT IS
THEY'RE TARGETING,

DRAG IT BACK INTO THE WATER
IN THE BLINK OF AN EYE.

JUST THE KIND OF WATER
WHERE THE ATTACK HAPPENED.

THERE'S ONE PROBLEM
WITH THIS IDEA.

WHILE CROCS WERE ONCE FOUND
THIS FAR SOUTH,

NONE HAVE BEEN SEEN ANY CLOSER THAN
150 MILES AWAY IN THE LAST 20 YEARS.

I WOULD BE SURPRISED THAT A CROCODILE
WHO IS BIG ENOUGH TO TAKE ON A HORSE,

A, WOULD GO UNNOTICED FOR LONG PERIODS OF
TIME, YOU KNOW, WAY OUTSIDE OF ITS RANGE,

AND, B, IN THAT SITUATION,
WOULD MISS.

YOU KNOW, IF IT'S IN DEEP WATER,
IT'S A LARGE ANIMAL,

AND IT'S GOING IN TO REALLY HAVE A GO,
YOU'D BE THE LUCKIEST HORSE ALIVE.

WHEN ALL AVENUES SEEM CLOSED, I
TURN TO THE LEAST UNLIKELY OPTION

IN MY PURSUIT OF THE TRUTH.

IF THE ATTACKER WASN'T A
CROCODILE, IT HAS TO BE A SHARK.

YET I NEED TO BE CERTAIN.

IF THIS IS THE TRUTH, IT HAS
FAR-REACHING REPERCUSSIONS.

IT WOULD SHOW CONCLUSIVELY
THAT SAVAGE BULL SHARKS

CAN AND WILL LAUNCH ATTACKS
IN FRESHWATER.

IT WOULD MEAN THERE IS NO KIND OF WATER
THAT'S SAFE FROM THESE PREDATORS.

BUT I'M LOOKING FOR PROOF.

I WANT TO SHOW SCIENTIST VIC PEDDEMORS
THE WOUNDS INFLICTED ON THIS RACEHORSE.

HE'S ONE OF THE WORLD'S LEADING
EXPERTS ON SHARK BITES.

SO, WHAT DO YOU MAKE
OF THAT?

WELL, I'D DEFINITELY SAY IT LOOKS
LIKE A SHARK BITE OF SOME DESCRIPTION

BECAUSE OF THESE GAPS BETWEEN THE
TOOTH AND THE WAY THAT IT SEEMS

TO HAVE SCRATCHED DOWN
THE HINDQUARTER OF THE HORSE.

THAT IS THE BITE
IN MORE CONTEXT.

WOW.

I THINK THIS IS JUST A HIT WITH
THE UPPER JAW AND A SLIP DOWN.

CAN YOU GET ANY IDEA FROM THAT ROUGHLY
HOW BIG THE SHARK MIGHT HAVE BEEN?

THIS ISN'T MUCH
OF A CRESCENT,

WHICH SUGGESTS THAT THE JAW
MUST HAVE BEEN FAIRLY BIG.

ASSUMING THAT THAT WAS THE SORT OF... THIS
PART OF THE JAW THAT HIT IT LIKE THAT.

SO, THE CURVE
IS QUITE GENTLE.

THE CURVE
IS VERY GENTLE.

SO, IF YOU THINK OF IT AS
HITTING LIKE THAT... MM-HMM.

NOW, IF YOU LOOK AT THIS TOOTH THERE, THAT
TOOTH THERE... IT'S A FAIRLY CLOSE MATCH.

THAT'S NOT TOO FAR
OFF A MATCH.

AND THIS IS
2.75 METERS IN LENGTH.

8 OR 9 FOOT.

IT'S A VERY SIMILAR
SORT OF CURVATURE.

AND IT LINKS IN WITH
OUR KNOWLEDGE OF BULL SHARKS.

WE... ONE WOULD EXPECT
A BIGGER BULL SHARK

UP IN A VERY FRESHWATER
COMPONENT OF THE RIVER.

THIS EVIDENCE SUGGESTS THAT THE CREATURE
THAT ATTACKED ALAN TREADWELL'S HORSE

IS A BULL SHARK...
OVER 8 FEET LONG.

AND BY HUNTING THROUGH
THE GOVERNMENT ARCHIVES...

I KNOW NOW HOW THESE ANIMALS
MANAGED TO GET OVER THE WEIR.

THE BRISBANE RIVER HAS FLOODED REPEATEDLY,
WITH ONE EXTREME OCCURRENCE IN 1974.

THE CITY ITSELF WAS INUNDATED, BUT
SO, TOO, WAS THE SURROUNDING AREA...

INCLUDING THE MOUNT CROSBY DAM.

IT SEEMS THAT, AS THE FLOOD
SUBSIDED, A COLONY OF BULL SHARKS,

SOME GROWING TO OVER 8 FEET LONG,
WERE LOCKED IN FAR UPRIVER.

AND IF THIS CAN HAPPEN HERE, IT CAN
HAPPEN ANYWHERE THAT BULL SHARKS ROAM.

THE DANGER THEY PRESENT
ISN'T RESTRICTED TO AUSTRALIA.

BULL SHARKS HAVE BEEN OBSERVED MOVING UP
THE MISSISSIPPI RIVER AS FAR AS ST. LOUIS.

AND THERE HAS EVEN BEEN AN ATTACK
REPORTED IN LAKE MICHIGAN.

TO FULLY UNDERSTAND THIS
THREAT, I WANT TO GET MY HANDS

ON ONE OF THESE BIG PREDATORS
IN FRESHWATER.

BUT TO DO THAT, I NEED TO LEARN
SOME SPECIALIST TECHNIQUES

FROM AN EXPERT
IN CATCHING BIG SHARKS.

HELLO, THERE.
YOU TERRY?

HOW YOU DOING? TERRY.
NICE TO MEET YOU.

NICE TO MEET YOU.
I'M BEN.

HELLO, THERE.

ON MARCH 14, 2007, JUST HERE IN THE
RIVER MOUTH, TERRY HESSE CAUGHT

A 9 1/2-FOOT-LONG FEMALE BULL SHARK
ESTIMATED TO WEIGH OVER 500 POUNDS.

THIS ALL LOOKS
LIKE PRETTY SERIOUS STUFF.

YEAH, WELL, FOR OUR RODS
AND REELS, WE USE ONE OF THESE.

RIGHT... COMPLETELY BLOWN AWAY
WITH THE IDEA OF USING A...

NEEDING TO USE
THAT IN A RIVER.

THESE GUYS ARE SERIOUS.
I'M IMPRESSED.

THEY'RE FISHING
IN THIS BUSY WORKING PORT

ON THE FRONTIER BETWEEN SEA
AND FRESHWATER.

ONE THING I'M NOTICING ALREADY
IS THE ATTENTION TO DETAIL.

THEY'VE GOT A COMPREHENSIVE PLAN TO OUTWIT
THE SUPERSENSORY CAPACITY OF THIS SHARK.

BULL SHARKS, LIKE ALL SHARKS,
HAVE TINY PINHOLES IN THEIR SNOUT

CALLED THE AMPULLAE OF LORENZINI,
USED FOR DETECTING ELECTRICAL FIELDS.

THEY'RE SO SENSITIVE
THAT THEY CAN DETECT

THE ELECTRICAL IMPULSES
OF A FISH'S HEARTBEAT.

SHARKS WITH WIDER HEADS, LIKE THE BULL
SHARK, HAVE MORE OF THESE PINHOLES,

AND THEREFORE, THEY CAN LOCK
ONTO PREY MORE ACCURATELY.

ANOTHER ONE THERE, OR... TO AVOID GIVING
OFF ANY ELECTRICAL SIGNALS TO THE SHARK,

TERRY MASKS ALL BUT THE METAL HOOK POINT
IN PLASTIC AND CABLE-TIES THIS TO THE EEL.

NEXT, TERRY'S MAKING SURE
HE CAPITALIZES

ON THE SHARK'S SMELL SENSE
BY USING FRESH BAIT.

2/3 OF THE SHARK'S BRAIN IS
DEVOTED TO SNIFFING OUT PREY.

AND BY FISHING AT NIGHT,

WE'RE CHOOSING THE MOST LIKELY
TIME FOR SHARKS TO GO HUNTING.

IT'S IN THE DARK WHEN
THE SUPERSENSORY BULL SHARK

HAS THE EDGE OVER FISH
THAT RELY MORE ON VISION.

TERRY BEGINS THE JOURNEY ACROSS THE
RIVER MOUTH TO PLACE THE BAITS.

BULL SHARKS HAVE BEEN REPORTED
TO RAM KAYAKS,

TAKING THE PADDLE SPLASH
AND RUDDER MOVEMENTS

FOR THE THRASHING
OF A FISH IN DISTRESS.

TERRY'S OKAY, BUT IN GETTING
THESE BAITS SET IN THE DARK,

I'VE INJURED MY INDEX FINGER.

IT'S GOING TO MAKE THINGS
DIFFICULT.

I'M JUST HOPING THAT THIS AND THE
DISTURBANCE FROM THE BUSY PORT

DOESN'T DAMAGE MY CHANCES.

PICK IT UP!
PICK IT UP!

AT 2:30 A.M... FISH ON!

WITH THE TIDE HIGH,
THE LINE BEGINS TO RUN.

WE'RE ON.

LET'S ACTUALLY
PUT THAT ON.

NO, OFF.
IT'S ALL RIGHT.

YEP.

STARTS SLOWING DOWN.

AT THE MOMENT, IT JUST FEELS
LIKE THERE'S A BOAT ON THE END.

THERE'S JUST A DEAD WEIGHT.

I'M JUST CHANGING
THE RATIO THERE.

YEAH, THAT... YEAH, THAT'S PULLING,
THAT'S PULLING, THAT'S PULLING.

IT IS COMING MY WAY.

AND WITH NEARLY 200 YARDS OF LINE TAKEN
IN, WHATEVER IT IS REACHES THE SHORE.

HOLY WHAT IS IT? THAT IS HUGE!

LIKE SOMETHING FROM "20,000
LEAGUES UNDER THE SEA,"

IT CERTAINLY ISN'T A SHARK.

BUT WHAT ON EARTH IS IT?

IT'S NOT A SHARK,
BUT IT IS AN EXCEPTIONAL FISH.

IT'S JUST REMARKABLE.

THAT IS SOMETHING,
ISN'T IT?

I'VE NEVER SEEN ANYTHING
LIKE THIS IN MY LIFE BEFORE.

IT'S WHAT THEY CALL
A QUEENSLAND GROUPER.

THIS IS A MONSTER.

IT'S NOT THE MONSTER I WAS
AFTER, BUT THIS IS A MONSTER.

WE'RE LOOKING
AT 6 FEET AND 3 INCHES.

WHAT ABOUT THE GIRTH?

YEAH.

2'1".
ITS GIRTH IS 4'3"... 4'3".

THIS IS A PROTECTED MARINE
FISH NORMALLY FOUND ON REEFS.

BUT THEY'RE KNOWN TO COME INTO RIVER
MOUTHS LIKE THIS ON RARE OCCASIONS.

LOOK AT THAT.

THIS FISH... EVEN TERRY AND BEN
HAVEN'T SEEN ANYTHING LIKE THIS

ANYWHERE LIKE THIS SIZE,
YOU KNOW.

SO IT'S JUST AN AMAZING CATCH
AND PARTICULARLY FROM A RIVER.

JUST, YOU KNOW, THIS THING
REALLY IS A RIVER MONSTER.

GROUPERS HAVE
AN EXTRAORDINARY TRICK.

THIS 250-POUND MALE ACTUALLY
STARTED LIFE AS A FEMALE.

WHEN THERE ARE TOO FEW MALES
IN A SPAWNING GROUP,

A FEMALE WILL SWITCH SEX
TO KEEP BREEDING NUMBERS UP.

OH. HA!

TIME, THOUGH, FOR THIS GENDER
BENDER TO HEAD BACK HOME.

TO ME, THAT JUST UNDERLINES
EVEN MORE THAN BEFORE

THAT, YOU KNOW, WE JUST HAVE NO IDEA AT
ALL WHAT IS DOWN THERE IN OUR RIVERS.

IT FEELS AMAZING TO CATCH A FISH LIKE
THAT, BUT IT'S NOT WHAT I'M HERE FOR.

ARMED WITH THE KNOWLEDGE I'VE GAINED
FROM TERRY, I'M DRIVING 50 MILES UPRIVER

FROM BRACKISH WATER
TO FRESHWATER.

I'M FISHING AT NIGHT.

I'M FISHING
WITH THE FRESHEST BAIT.

SO... AND I'M PUTTING
OUT TWO RODS.

HERE WE GO. LOOK.

SOMETHING...
SOMETHING HAD THAT.

BUT IT DIDN'T HAVE
THE HOOK IN ITS MOUTH.

SO, WHATEVER IT WAS, IT'S STILL OUT THERE,
AND I'M RUNNING OUT OF BAIT NOW, SO...

IT'S ANNOYING.

FINALLY, I'M IN LUCK.

I'VE GOT A TAKE
ON THE OTHER ROD.

AND KEEP IT AWAY FROM SOME TREES
AND STUFF ON THE SIDE THERE.

YEAH, IT'S A SHARK.
IT'S A SHARK.

UP WE COME.

THIS IS A SHARK IN A RIVER.
OKAY.

THIS MAY BE A SMALL ONE, BUT FOR ME,
THIS IS, IN SOME WAYS, MORE UNSETTLING.

UP ONTO THE GRASS.

I ALREADY KNOW THERE ARE
BIG FEMALES IN THIS RIVER.

CATCHING ONE LIKE THIS IMPLIES
THEY'RE BREEDING HERE.

THAT BODY IS JUST SOLID MUSCLE.
YOU JUST FEEL IT.

WHEN IT DECIDES TO FLEX, THAT'S
JUST GOT SO MUCH STRENGTH THERE.

THIS ONE DIDN'T SWIM
ALL THE WAY FROM THE OCEAN.

IT WAS MOST LIKELY BORN IN
BRACKISH WATER JUST DOWNSTREAM.

AND WHILE ONLY 18 MONTHS OLD, IT
SEEMS TO BE THRIVING IN FRESHWATER.

IT'S A SCARY THOUGHT
THAT THIS RIVER

WILL BE ITS HUNTING GROUND
FOR LIFE... ANOTHER 15 YEARS.

"AT 3'6" LONG
AND 15 POUNDS IN WEIGHT,

THIS ONE COULD TRIPLE IN LENGTH
AND BECOME 30 TIMES HEAVIER.

I'M JUST TRYING TO IMAGINE THIS THING TWO
OR THREE TIMES THE LENGTH IN THIS WATER.

IT'S QUITE A FRIGHTENING PROSPECT
IN A RIVER, A SMALL RIVER.

ANYWAY, THIS ONE'S GOING BACK.

WELL, I'VE BEEN ABLE TO PROVE,
WITHOUT QUESTION,

THAT BULL SHARKS ARE TRESPASSING
ON MY PATCH, IN FRESHWATER,

MORE THAN 80 MILES
UP AN AUSTRALIAN RIVER.

BUT CRITICALLY, WHAT I'VE LEARNED IS THAT
THEY HAVE THE CAPACITY FOR BRUTAL ATTACKS

IN FRESHWATER ALMOST ANYWHERE.

THERE ARE FEW LIMITS TO WHERE
THIS SHARK WILL OPERATE.

MORE AND MORE, IT SEEMS
THAT THIS FRESHWATER JAWS

IS BRINGING ITS SAVAGERY
INTO OUR ONCE-TAME BACKYARD.

ALONG METROPOLITAN CANALS, UP QUIET
RIVERS, AND ON TRANQUIL LAKES,

THE BULL SHARK IS LOOKING
FOR ITS NEXT MEAL.

IT'S JUST A QUESTION
OF WHO AND WHEN.
