Narrator: CURLY IS 18 FEET OF PURE BITING MACHINE.
Skomal: OH-HO!
WITH A FORCE OF NEARLY 2 TONS PER SQUARE FEET,
IT SAWS OFF HUNKS OF FLESH THE SIZE OF TRASH CANS.
SON OF A... GOD!
Woman: THE SHARK KNOWN AS AIR JAWS WAS SPOTTED CLOSE TO SHORE.
Narrator: 1-TON, 25-MILE-PER-HOUR FLYING GREAT WHITE.
THESE ATTACKS CAN LAST A MERE ONE SECOND.
LIKE A CAR CRASH,
IT'S FASTER THAN A HUMAN BRAIN CAN PROCESS.
Man: THEY'RE LITERALLY BUILT LIKE A TANK.
THEY MAX OUT AT AROUND 20 FEET.
THEY'RE THICK, THEY'RE STRONG,
AND THEY'VE GOT A MASSIVE HEAD
THAT'S FILLED WITH HUNDREDS OF RAZOR-SHARP TEETH.
SO THEY CAN ACT FIRST AND ASK QUESTIONS LATER.
THAT SHARK PROBABLY LEFT MORE OF A LASTING IMPRESSION ON ME
THAN I DID ON IT.
Narrator: THE THRESHER SHARK.
FISH LIKE SARDINES SCHOOL IN DENSE CLUSTERS
AS A DEFENSE AGAINST PREDATORS,
BUT THE THRESHER HAS EVOLVED A COUNTER STRATEGY.
RARE VIDEO HAS CAUGHT THE THRESHER'S LETHAL NINJA MOVE
IN ACTION, BUT ONLY FROM A DISTANCE.
THE THRESHER SPEEDS TOWARD SCHOOLING FISH
AND USES ITS TAIL LIKE A WHIP.
THE TIP OF THE TAIL MAY REACH SPEEDS OF 50 MILES PER HOUR.
Man: A BEAUTIFUL FEMALE. SHE'S VERY BIG.
IT IS LUPITA, WHICH IS SHORT FOR GUADALUPE.
Narrator: HEAVILY PREGNANT,
LUPITA'S TRIP IS ALL ABOUT FATTENING UP ON ELEPHANT SEALS.
SHE COULD GIVE BIRTH TO UP TO 14 LIVE PUPS.
LUPITA. I LIKE THAT NAME A LOT.
THE OCEANIC WHITETIP.
THE OCEANIC WHITETIP CAN DO THESE LONG MIGRATIONS
WITHOUT FOOD SOURCES.
Wharton: THEY LIVE FAR FROM LAND, FAR FROM NUTRIENTS,
LIKE A FOOD DESERT.
Narrator: THE WHITETIP HAS EVOLVED THE PATIENCE OF A ZEN WARRIOR,
BUT WHEN FOOD IS SUDDENLY PLENTIFUL,
IT LAUNCHES INTO A FEEDING FRENZY.

THE HAMMERHEAD.
IT'S MASTERED THE ART OF DETECTION.
ALL SHARKS SENSE ELECTRIC CURRENTS
GENERATED BY LIVING THINGS
USING SPECIAL RECEPTORS ON THEIR SNOUTS.
BUT HAMMERHEADS TAKE THIS EXTRASENSORY SKILL
TO A NEW LEVEL.
THOUSANDS OF RECEPTORS ARE PACKED
INTO THEIR UNIQUE HEAD SHAPE.
IT'S LIKE THIS HUGE METAL DETECTOR
JUST RUNNING ALONG THE SAND,
TRYING TO SENSE LITTLE, MINUTE THINGS UNDERNEATH THEM.
AND IT DOES SENSE IT BETTER THAN ANY OTHER SHARK.

Woman: WE JUST HAD A BIG HIT. WOW. LOOK AT THAT.
Narrator: A 20-FOOT GREAT WHITE SHARK CALLED DEEP BLUE.
Man: IT'S A BIG GIRL, EH?
WITH A MASSIVELY SWOLLEN BELLY,
SHE IS HEAVILY PREGNANT AND HUNGRY.
AND IN AN EXTRAORDINARY TWIST, SHARK CAM HAS BECOME THE PREY.
MATILDA -- A FULLY MATURED GREAT WHITE.
SHE HAS ALREADY PASSED THE GREATEST TEST OF ANY SHARK...
...BREACHING ON PREY.
MATILDA IS A WARRIOR.
NOW SHE IS A ROLE MODEL FOR ALL THE YOUNG SHARKS IN THE ALLEY.
THE MEGAMOUTH.
Stone: TILL 40 YEARS AGO,
NO ONE EVEN KNEW THIS GIANT OF THE SEA EXISTED.
SCIENTISTS DESCRIBED IT AS AN ALIEN
COMING OUT OF THE DEPTHS.
Narrator: WHEN IT OPENS ITS HUGE JAWS,
BIOLUMINESCENT GLOW AROUND ITS LIPS
LURES KRILL RIGHT INTO ITS MOUTH.
Man: SO, YOU CAN REALLY APPRECIATE
JUST WHAT A SPECIALIZED PREDATOR THESE ARE.
THEY'RE JUST FINELY TUNED
FOR THE ENVIRONMENT IN WHICH THEY'RE FEEDING IN.
THIS IS A SMALL ONE, AND I THINK I MIGHT FIT IN HIS MOUTH
