  • I'M LUKE TIPPLE, AND THIS IS YOUR "DAILY BITE."

  • SHARK WEEK HAS BEEN HOME TO SOME OF THE GREATEST

  • SHARK DISCOVERIES OVER THE YEARS,

  • AND TODAY, WE'RE TAKING A LOOK

  • AT THE YEAR'S BIGGEST BREAKTHROUGHS --

  • FROM THE RE-EMERGENCE

  • OF A PREVIOUSLY THOUGHT-EXTINCT SPECIES

  • TO NEVER BEFORE SEEN BEHAVIORS.

  • LET'S DIVE IN.

  • FORREST GALANTE HAS MADE IT HIS LIFE'S MISSION

  • TO SEARCH FOR EXTINCT ANIMALS.

  • AND THIS YEAR, HIS TEAM FOUND UNDENIABLE EVIDENCE

  • THAT A HIGHLY ADAPTIVE SPECIES

  • HAS POSSIBLY JUST BEEN SMART ENOUGH TO EVADE HUMAN CONTACT

  • SINCE THE '70s.

  • THE PONDICHERRY SHARK HAS BEEN CONSIDERED EXTINCT FOR YEARS.

  • BUT THE FISHERMAN IN THE INDIAN OCEAN BEGAN REPORTING SIGHTINGS

  • OF A STRANGE SHARK THAT MATCHED ITS DESCRIPTION.

  • Galante: GUYS, LOOK AT THIS. I'M NOT EVEN KIDDING. LOOK.

  • Narrator: FORREST RECEIVES THE NEWS ABOUT JESSICA'S FIND.

  • A FISHERMAN CAUGHT TWO SHARKS

  • MATCHING THE DESCRIPTION OF THE PONDICHERRY.

  • JESSICA TAKES A SMALL CLIPPING OF THE FIN,

  • AND SHE ALSO REMOVES A TOOTH.

  • THESE SAMPLES WILL BE SENT BACK TO THE LAB FOR GENETIC TESTING

  • AND IT WILL BE SEVERAL DAYS

  • BEFORE THEY CAN POSITIVELY IDENTIFY THIS SPECIES.

  • JUST WHEN IT SEEMS ALL IS LOST,

  • FORREST RECEIVES THE RESULTS OF THE GENETIC TESTS

  • TAKEN FROM THE SPECIMEN FOUND IN THE FISHING VILLAGE.

  • Galante: I'M, LIKE, ON THE EDGE OF MY SEAT.

  • THE WHOLE TEAM'S HERE.

  • JESSICA: Yeah.

  • ARE YOU 100% SURE?

  • -Yeah. -SWHOOOOOOOOO!

  • [ LAUGHS ]

  • WE HAVE THE GENETIC PROOF.

  • THAT IN ITSELF WILL REMOVE THE ANIMAL

  • FROM THE EXTINCT SPECIES LIST

  • AND PLACE IT ON THE CRITICALLY ENDANGERED LIST.

  • ♪♪

  • LAST YEAR ON SHARK WEEK,

  • ANDY CASAGRANDE DISCOVERED WHAT APPEARED TO BE

  • TWO BROTHER SHARKS PROWLING THE OCEANS TOGETHER

  • AND HUNTING AS A TEAM.

  • THIS YEAR, HE DOVE FURTHER INTO THE MYSTERY

  • AND UNCOVERED SOME OF THE MOST UNPRECEDENTED

  • SHARK BEHAVIOR EVER CAPTURED ON CAMERA.

  • WE FOUND THESE TWO SHARKS, AND I SWEAR TO GOD,

  • HAVE TO BE BROTHERS.

  • THEY SWAM THE SAME, THEY ACTED THE SAME,

  • ROUGHLY THE SAME SIZE, MATCHING BIRTHMARKS.

  • Dr. Ferrara: THESE TWO SIBLINGS ARE STAYING TOGETHER.

  • TO MY KNOWLEDGE,

  • THAT'S NEVER BEEN DOCUMENTED BEFORE FOR WHITE SHARKS.

  • Narrator: ANDY CASAGRANDE AND HIS TEAM

  • HAVE FOUND THE SHARK BROTHERS,

  • STILL SWIMMING SIDE BY SIDE AFTER 14 MONTHS.

  • Casagrande: THIS IS INCREDIBLE!

  • THEY'RE CIRCLING THE UNDERWATER DRONE.

  • THIS IS STRATEGY, NOT MINDLESS PREDATION AT ALL.

  • Narrator: WHILE ONE DISTRACTS FROM IN FRONT,

  • THE OTHER MAKES A MOVE.

  • THE BROTHERS DEMONSTRATE A STRATEGY

  • SIMILAR TO LAND-BASED PACK HUNTERS.

  • THEY MAY HAVE BEEN USING THIS TECHNIQUE ON ANDY

  • WHEN HE FIRST FOUND THE BROTHERS TOGETHER MORE THAN A YEAR AGO.

  • IT'S PRETTY AMAZING.

  • DUDE.

  • SEALS DON'T STAND A CHANCE.

  • NO WAY. NOT AGAINST THE BROTHERS.

  • THESE ARE DEFINITELY GREAT WHITE SHARK BROTHERS.

  • IT MAKES SENSE TO ME BIOLOGICALLY

  • AND JUST COMMON SENSICALLY

  • THAT GREAT WHITE SHARKS WOULD HAVE BROTHERS AND SISTERS

  • AND THEY LIKELY HANG OUT WITH EACH OTHER,

  • HUNT WITH EACH OTHER, LEARN FROM EACH OTHER.

  • THEY HAVE FAMILIES.

  • ON "THE LAWS OF JAWS," A HIGHLY SKILLED DIVE TEAM

  • HAS PUT THEIR LIVES ON THE LINE TO PROVE AND DISPROVE

  • REAL-LIFE SHARK ENCOUNTERS

  • TO DETERMINE WHAT REALLY INFLUENCES SHARK BEHAVIOR.

  • THIS YEAR, PAUL DE GELDER WENT TO THE ABSOLUTE EDGE OF DANGER,

  • DIVING UP CLOSE AND PERSONAL WITH SHARKS

  • WITH ACTUAL BLOOD IN THE WATER TO PROVE ONCE AND FOR ALL

  • WHETHER SHARKS HAVE A TASTE FOR HUMAN BLOOD.

  • De Gelder: WE'VE BEEN TAUGHT THAT SHARKS CAN SMELL A DROP OF BLOOD.

  • IF YOU HAVE A SMALL CUT,

  • THEN THEY'RE GONNA BE ATTRACTED TO YOU.

  • ♪♪

  • BUT SO MUCH ELSE ABOUT THE SHARKS HAS BEEN

  • A PRECONCEIVED NOTION THAT'S UNTRUE.

  • MAYBE THIS IS, TOO.

  • Narrator: PAUL WILL BE 50 YARDS FROM THE SAFETY OF THE BOAT

  • WITH JAMIN AND NICK BELOW.

  • IN THE FIRST PART OF THE TEST,

  • PAUL WILL RELEASE THE HUMAN BLOOD

  • IN A CLOUD AROUND HIMSELF.

  • THEN, IN THE SECOND HALF OF THE TEST,

  • FISH BLOOD WILL BE POURED INTO THE WATER.

  • IF THERE IS A RESPONSE TO EITHER,

  • HE'LL THEN NEED TO GET HIMSELF TO SAFETY.

  • THE STAGE IS SET TO TEST THE FIRST PHASE OF THE EXPERIMENT.

  • A SHADOW APPEARS.

  • Nick: HERE COMES A TIGER.

  • THE SHARKS HAVE ABSOLUTELY NO REACTION TO THE HUMAN BLOOD.

  • WHEN YOU FIND OUT THAT SOMETHING THAT'S COMMONLY BELIEVED

  • IS TOTALLY FALSE, IT'S AMAZING.

  • SO YOU JUST LEARN THIS NEW FACT, YOU PUT IT IN YOUR TOOLKIT,

  • AND THEN YOU MOVE ON TO THE NEXT ONE.

  • ♪♪

  • SHARK WEEK HAS MADE A HUGE IMPACT

  • ON PROTECTING THESE VULNERABLE SPECIES,

  • PERFORMING IMPORTANT WORK

  • THAT HAS HELPED PASS LEGISLATION AROUND THE WORLD.

  • DON'T MISS THE REST OF THIS YEAR'S INCREDIBLE DISCOVERIES,

  • ALL AVAILABLE TO WATCH ON DISCOVERY GO.
