Big Blue Live Episode 2

>> THE GRATEST GATHERING IS >> GREAT WHITE SHARKS, APEX PREDATORS OF OUR GATHERING THEY'RE ALSO COMING YOUR WAY AND STEVE WILL BE DIVING WITH OUR SEA LIONS.

THIS IS "BIG BLUE LIVE."

♪ SANJAYAN: HELLO AND WELCOME BACK GREATEST GATH OTHERING OF MARINE LIZ: WE'RE WORKING VERY CLOSELY SCIENTISTS TO BRING YOU THE LATEST WILDLIFE AND IT IS ALL HAPPENING.

WE ALSO WANT TO WORK WITH YOU.

IF YOU SPOT ANYTHING INTERESTING IN THE AREA LET US KNOW.

USE #BIGBLUELIVE.

SANJAYAN: IF YOU WERE WATCHING YESTERDAY, THIS COMPLETELY COVERED.

WE'VE GOT BOATS, HELICOPTERS AND OF COURSE OUR LIVE CAMERAS.

LET'S CHECK IN OUR AMAZING HELICOPTER PILOT.

EIGHT HUMPBACKS ON THE SURFACE COMING UP FOR FEEDING.

LIZ: BEAUTIFUL, BEAUTIFUL SHOTS.

THEY ARE HONING IN ON SOME SOURCE AS THEY ALWAYS DO.

THEY DON'T TRAVEL ON THEIR OWN.

ANIMALS.

IT'S MORE OF A FISH INFUSION WHEN THERE'S FOOD THEY EITHER COMMUNICATE VOCALLY BECAUSE THEIR SOUNDS TRAVEL UP TO 20 BREACHES AND THOSE FIN SLAPS.

SANJAYAN: THOSE FIN SLAPS ORGANIZE THEM TO ORGANIZE THEIR POD.

IT'S PARASITES OFF AND THAT'S WHY THEY'RE DOING THIS.

>> WE'RE GOING TO SEND AARON TO A REAL CHECK OUT WHAT HE GOT EARLIER.

LIZ: EARLIER ON TODAY IF YOU LOOK VERY CLOSELY TOWARDS THE MIDDLE TO RIGHT OF THERE IS A SHADOW RIGHT OFF THE BEACH, A COUPLE OF HUNDRED FEET GREAT WHITE LIZ: UNDENIABLY A GREAT WHITE SHARK.

SANJAYAN: LOOK AT THIS POOR GUY.

RIGHT THERE.

LIZ: YOU SAY "POOR."

HE IS ENJOYING HIS DAY.

AND THE SHARK DOESN'T EVEN BOTHER THEM.

SANJAYAN: THAT'S EXACTLY WHAT WE WANT.

DELIVERING.

ARE YOU LIKELY TO SPOT SHARKS TODAY AS WELL AS THOSE GLORIOUS HUMPBACKS?

AARON: WE HAVE SEEN A FEW GREAT WHITES.

WE'VE SEEN ABOUT FIVE OF THEM AT THE SHORELINE.

CURRENTLY WE'RE AT MOSS LANDING AND WE DID SEE SOME DOLPHINS AND ORCAS.

THE DOLPHINS FLEEING FROM THOSE ORCAS.

LIZ: I WAS ONLY ASKING FOR GREAT WHITE SHARKS.

HUMPBACKS, GREAT WHITES ARE ALL IN THE HERE TODAY.

AARON WILL DELIVER FOR YOU.

BUT LOOK AT THAT I CANNOT GET ENOUGH OF THOSE WONDERFUL, WONDERFUL MARINE LET'S CHECK ON THE SEA LIONS, BASKING IN THE SUNLIGHT, DIGESTING AFTER FEEDING IN THE WATER.

THESE GORGEOUS ORTES.

-- OTTERS.

GUY.

I SHOULD SAY LITTLE GIRL, OTTER NUMBER 696.

LIZ: SHE'S A HONEY.

NUMBER 696 BECAUSE SHE'S THE 696TH OTTER TO BE BROUGHT IN.

SANJAYAN: AND WE'VE GOT EXPERTS THAT ARE COMING OUT HERE COMING.

LIZ: INDEED.

HOW MUCH EVEN WHILE WE'RE ALIVE IN ONE HOUR.

>> LARGEST BODY OF WATER ON OUR PLANET.

LIZ: ANYTHING COULD HAPPEN.

SANJAYAN: I'M JUST PITCHING MYSELF.

GOING NUTS.

♪ LIZ: OH, MY GOD.

>> OH, MY GOD, LOOK AT ITS MOUTH!

LIZ: KATE SPENCER OUR WHALE EXPERT HAS JOINED US BECAUSE AS AARON TOLD US HE HA SPOTTED SOME ORCAS AN LOTS OF ACTIVITIES THESE ARE THE SHOWS HE GOT JUST BEFORE WE WENT ON AIR.

KATE, TALK ME THROUGH THIS.

THAT'S A MOTHER AND HER THREE OFFSPRING TRAVELING TOGETHER.

SOME AREA AND THE BABY TRYING TO NUDGE THE KILLER WHALES OUT OF THE THEY SORT OF HARASS THEIR PRIMARY PREDATORS.

THOSE ARE ADULT HUMPBACKS.

THESE ARE >> THEY'RE LIKE FIREWORKS AT THE RIGHT OF THE SCREEN THERE THE WAY THEY JUST BOLTED.

THE THEIR -- THE WAY OF THEIR WE'VE BEEN SEEING HUMPBACKS AND DOLPHINS FEEDING.

INTO THE AREA, LIZ: LOTS OF SEA BIRDS.

IS IT UNUSUAL SEEING THE HUMPBACKS -- IT'S ALMOST LIKE THEY'RE TRYING TO HELP THE DOLPHINS.

KATE: MAYBE NOT HELP THEM GIVE THEIR PREDATOR AS HARD TIME.

HERE WE SEE BIRDS FEEDING ON SOMETHING LEFT BY THE KILLER WHALE.

WE SEE THEM INTERACTING WITH KILLER WHALES.

LIZ: HOW MUCH IS GOING ON.

THIS REALLY IS BUILDING UP TO A PEAK.

LOOK AT THAT.

ORCAS AWAY.

DO YOU SEE THAT A LOT ON YOUR BOAT?

KATE: WE SEE IT OCCASIONALLY AND IT'S SOMETHING I'VE SEEN LIZ: I'M UTTERLY BLOWN.

OUR EXPERTS WILL BE ANALYZING ALL OF THE FOOT G AND WILL TELL YOU MORE ABOUT THAT EVENT ON TOMORROW'S SHOW.

SANJAYAN: THAT'S REALLY EXTRAORDINARY SEEING ALL OF THAT WILDLIFE.

THE GATHERING IS WELL UNDERWAY AND WEIRD, WONDERFUL CREATURES THAT WE DIDN'T EXPECT TO SEE THIS TIME OF YEAR.

IT'S BEEN SEASONS THAT I CAN REMEMBER.

SO I'M JOINING DR. STEVEN WEBSTER.

WITH THE AQUARIUM SINCE IT BEGAN.

DR. WEBSTER: 35 YEARS AGO WE'VE BEEN TALKING ABOUT AN AQUARIUM, SANJAYAN AND I'VE BEEN STUDYING SANJAYAN: SO YOU ARE A LOCAL.

YOU THINK IT'S A BIT OF AN DR. WEBSTER: IT'S WEIRD, CRAZY AND NOTHING LIKE I'VE SEEN IN OVER 50 YEARS.

SANJAYAN: LET'S TAKE A LOOK AT A FEW THINGS THAT HAVE BEEN SHOWING TALK US THROUGH THIS.

MAKING THEIR WAY FROM MEXICO.

SANJAYAN: THEY'RE HERE ON THE BEACH.

DR. WEBSTER: WE HAVE BROWN BOOBIES HERE AND ACTUALLY A BLUE-FOOTED BOOBY WAS SEEN OFF THE COAST OF SAN FRANCISCO.

THEY'RE NORMALLY TROPICAL.

SHOWED UP IN SAN FRANCISCO.

AND COMMON DR. WEBSTER: WE WOULD HAVE THEM OFFSHORE AND NOW WE'RE SEEING SANJAYAN: AND GLIMPSES OF WHITE SHARKS.

WE HAVE A LOWE.

YOU'RE GOING TO KEEP AN EYE AND IF A GREAT WHITE DOES SHOW UP YOU'RE GOING TO RIGHT THERE TO HELP US WALK THROUGH IT.

CHRIS: HAPPY TO DO IT.

SANJAYAN: IT SEEMS CLEAR THAT THIS IS LINKED TO WARMER WATERS.

WE KNOW THAT CLIMATE CHANGE IS WARMING THE WORLD'S OCEANS.

MORE ACUTE.

AND IT SEEMS TO BE ON TOP OF ALL OF THAT.

WHAT'S GOING ON?

LIZ: I'VE BEEN HAVING A CHAT WITH OTHER EXPERTS AT MONTEREY BAY AQUARIUM.

FIRST FAHRENHEIT.

THAT'S FIVE DEGREES WARMER THAN YEAR.

WE'VE SEEN SOME OF THE WARMEST TEMPERATURES SINCE RECORDS BEGAN.

IS AN EL NINO YEAR.

THIS IS WHICH IS A RESULT OF WIND AND WATER MOVEMENTS ACROSS THE PACIFIC.

EL NINO AFFECTS WEATHER PATTERNS ALL ACROSS THE WHAT ESSENTIALLY HAPPENED HERE IS THAT MORE USUAL STAYS OFF THE COAST OF CALIFORNIA REPRESENTED BY THESE RED ARROWS HERE.

NOW ADD TO THIS THAT FOR THE PAST TWO YEARS A MYSTERIOUS MASS OF WARM WATER MEASURING 1,000 FEET IN AROUND OFF THE COAST HERE.

SCIENTISTS THEY'RE STILL NOT SURE EXACTLY WHY.

THEY THINK EL NINO AND THE BLOB SEEM TO BE THE CAUSE OF THE WATER TEMPERATURE HERE.

THEY JUST DIVE AS THEY DO.

BUT THEY ARE DEFINITELY CARRYING A LOT OF ACTIVITY ON THESE I WOULD LOVE IF WE COULD SEE -- SHALL WE PUT THAT IN OUR LIVE AARON HAS JUST MESSAGED US AND SAID HE'S RIGHT OVER THEM.

THEY ARE STILL FEEDING.

AS MUCH AS WE'RE GOING TO GIVE YOU MORE INFORMATION ON THAT DOLPHIN THEY'RE LOOKING FOR FOOD.

LIVE BOXING THERE.

WE'RE GOING TO LOOK INTO HOW THESE UNUSUAL CONDITIONS ARE AFFECTING ALL OF THAT ARE GATHERING HERE THIS YEAR.

AND ONE OF VISITORS IS, OF COURSE, THE GREAT WHITE SHARK.

WEIGHING IN AT OVER TWO TONS, THE GREAT WHITE SHARK IS THE LARGEST, MOST NORE TORES YOU PREDATORY CRUISING THE COOL COASTAL WATERS OF THE WORLD, THESE WARM-BLOODED UP TO SHAPED LIKE A TORPEDO OF MUSCLE, THEY ACCELERATE SPEEDS OF 35 ♪ PREDATORS.

THEY CAN DETECT A DROP OF BLOOD IN 25 GALLONS OF WATER AND SMELL AWAY.

THEY'RE EVEN SENSITIVE TO VIBRATION AND THE ELECTRICAL PASSES OF THEIR PREY.

THEY'RE TOUGH, THE TOP OF THE >> NOW, LIZ AND I THINK THE GREAT WHITE SHARKS ARE SUCH INCREDIBLE ANIMALS BUT WE WANT TO KNOW WHAT YOU THINK.

I WATCHED "JAWS."

I WAS SO SCARED THAT I COULDN'T TAKE STANDING AT THE DOOR.

DON'T TELL ANYONE -- LIZ: YOU YOU KNOW BETTER NOW.

SHARKS OR PERHAPS YOU'RE NOT SURE.

LIZ: WHY DON'T YOU GET ONLINE AND USE #SHARKFEAR.

>> WE MIGHT CHANGE A FEW MINDS.

LIZ: LET'S GO BACK TO CAPTAIN AARON.

HERE RIGHT OVER HUMPBACKS AND ORCAS.

>> AARON?

LIZ: CAN YOU SEE ANYTHING COMING UP FOR BREATH AT THE MOMENT?

ALL THESE MARINE MAMMALS.

THEY COME UP FOR BREATH AND RIGHT NOW WATER.

TANTALIZINGLY CLOSE TO GETTING SOME MORE TONIGHT'S SHOW.

>> NOW THE KEY TO THIS GATHERING IS A FOOD SOURCE AND STEVE HAS GONE OUT TO INVESTIGATE ONE OF THE AREA'S TOP RESTAURANTS.

STIVE I'M NO MORE THAN A MILE ABY FROM Y WHERE YOU GUYS ARE.

I CAN ACTUALLY SEE THE AQUARIUM AT THE BREAK WATER.

CALIFORNIA IT'S PREDATORS THINGS LIKE GREAT WHITE SHARKS.

WE HAVE BEEN SEEING EVIDENT BETWEEN SHARKS AND SEA LIONS.

IF YOU'RE EATING RIGHT THESE IMAGES ARE A LITTLE BIT GRAPHIC.

BUT THESE ARE VERY DEFINITELY BITE MARKS FROM SHARKS.

THEY'RE A CLASSIC CRESCENT SHAPE.

AND SOME OF THESE PRETTY BRUTAL.

THEY'RE VERY RESILIENT AND THE ONES THAT SURVIVE THE ATTACKS WILL PROBABLY CARRY ON TO FLOURISH.

TO TELL ME AQUARIUM SHARK BIOLOGIST DR. SAL JORGENSON.

SAL, THE GREAT WHITES THAT COME COME DR. JORGENSON: THAT'S RIGHT.

THESE FOR HAWAII, REALLY.

AND THEY'RE CONVERGING TO THIS >> AND THEY MAY NOT HAVE EATEN FOR THE ENTIRE TIME.

DR. JORGENSON: THEY'RE TAPPING INTO THEIR ENERGY RESERVES JUST TO TRAVEL THIS FAR.

>> THIS THEM.

>> THAT'S ABSOLUTELY RIGHT.

SANCTUARIES LIKE THIS AND OTHER ISLANDS UP AND DOWN.

OUR TAGGING STUDIES SHOW THAT THE RAPIDLY IN BETWEEN THEM AND THEY SWIM AROUND LOOKING FOR THEIR NEXT MEAL.

>> TELL ME ABOUT THE TAGGING WORK YOU'VE BEEN DOING.

DR. JORGENSON: MORE COLLEAGUES AND I HAVE BEEN WORKING AT THESE FIELDS AND THAT'S WHERE WE'RE ABLE TO PLACE ELECTRONIC TAGS ON THESE SHARKS.

SO WE'VE BEEN TRACKING THEM UP AND DOWN THE COAST.

IT'S A VERY WARM YEAR.

IT'S AN EL WE'VE HAD A LOT OF EARLY REPORTS ESPECIALLY SMALLER IS VERY UNUSUAL.

AND WE'VE BEEN HITS FROM OUR TAGGING.

IN FACT, WE'VE GOT HITS INSIDE THE BAY AS LATE AS THIS MORNING.

>> WOW, THAT'S QUITE SOMETHING.

I HORRIFIED THAT HERE IN A POPULAR STATE LIKE CALIFORNIA, 40 MILLION PEOPLE LIVE HERE THAT THERE ARE GREAT SHARKS.

WHY AREN'T THERE MORE ATTACKS?

YOU CAN SEE IN CLEAR WATERS THESE SHARKS WILL DO ANYTHING TO AVOID HUMAN BEINGS.

THEY WILL SWIM RIGHT AROUND YOU.

INTENDED PREY.

THE STATISTICS REALLY BARE THAT OUT.

IN THE STATE OF CALIFORNIA THERE'S AROUND ONE HUMAN FATALITY A DECADE.

YOU'RE AT LEAST 10 TIMES MORE LIKELY TO BE KILLED BY A BOLT OF LIGHTNING.

SO PLEASE BE FASCINATED BY THESE ANIMALS BECAUSE THESE SHARKS THEY REALLY WHATSOEVER.

HERE WE HAVE THE OPPORTUNITY TO DIVE WITH SEE LIONS PARTICULARLY AT THE POINT TO THE SOUTH OF HERE CRYSTAL, CRYSTAL CLEAR AND THE EXPERIENCE WAS REALLY QUITE SOMETHING.

>> WELL, THIS IS A TRULY UNBELIEVABLE WE ARE SEA LIONS.

THESE CREATURES ARE COMPLETELY TRANSFORMED HERE UNDERWATER WELLS.

HERE THEY ARE AGILE, GRACEFUL USING THOSE EXTRAORDINARY WING-LIKE FRONT FLIPPERS.

THEY BUT IT'S NOT THE BLAST OF SPEED THAT SENDS THEM ACROSS.

IT'S THEIR ACCELERATION, THEIR MANEUVERBILITY AND IT DOES MAKE THEM REAL CHALLENGES FOR GREAT WHITE SHARKS.

BELOW TRYING TO TAKE THE SEA LIONS BY SURPRISE.

IF THE SEA LIONS SPOT THEM THEN THEY HAVE THE AND WITH THOSE DARK EYES AND LARGE TACTILE WHISKERS THEY HAVE THE OCEAN AT THEIR DISPOSAL TO SEE WHERE SHARKS ARE AROUND.

THEY'RE ALWAYS LOOKING AROUND FOR A PREDATOR.

THEY'RE STAYING IN CLOSE TO THE ROCK.

THIS IS WHAT YOU OFTEN SEE WHEN THERE ARE SHARKS AROUND.

THEY'RE ALWAYS LOOKING OUT INTO THE BLUE IN CASE THERE'S A SHARK AROUND.

LOOK AT THIS.

UP AGAINST MY TOES.

SO, SO MUSICAL.

THEY'RE LIKE A TORPEDO THROUGH THE WATER.

AND IT'S INTERESTING.

THEY ARE SO INTELLIGENT THAT IF THEY THINK YOU MIGHT BE SOMETHING THAT YOU CAN PLAY WITH, THEN THEY'LL BE MUCH MORE INTERESTED.

>> THAT WAS REALLY VERY SPECIAL.

BUT WE ARE ABOUT TO DO ANOTHER WATER.

IT'S A SLIGHTLY DIFFERENT ENVIRONMENT.

WE HAVE A KELP FOREST HERE BUT IT'S A GREAT OPPORTUNITY TO GET A SENSE OF THE WORLD OF THE SEA LION AND OF THE SHARK.

I WANT TO JUMP OUT OF THE BOAT.

I'M SO EXCITED BECAUSE THERE'S SO MUCH LIFE OUT HERE.

BUT I CATCH UP WITH OUR SEA OTTERS THESE LITTLE CUTE CUDDLY ANIMALS NATION'S HEART.

THERE'S ONE PARTICULAR OTTER THAT ALL OF YOU AND I CAN CLEARLY UNDERSTAND WHY HAVE ALL FALLEN IN LOVE AND THAT'S BIXBY AND A FIVE-WEEK-OLD PUPU.

AND WE KNOW THAT LITTLE PUP IS A GIRL.

WE'VE BEEN GETTING LOADS AND LOADS OF MESSAGES FROM FACEBOOK READ A COUPLE OF -- READ A COUPLE OF THOSE TO.

CUTEST NAME FOR ANY OTTER.

>> OBVIOUSLY IT WAS NAMED AFTER BIXBY BRIDGE.

I ALSO HAVE A QUESTION FROM JAN DO SEA OTTERS HAVE ANY NATURAL PREDATORS?

THEY DO AND WE'RE GOING TO SECONDS HERE.

WE WANT YOU TO KEEP THOSE QUESTIONS COMING.

THERE'S A LOT MORE ABOUT SEA OTTERS AND THEIR LIFE HERE FROM OUR ONLINE EFFORT.

SO GO TO PBS.

PUP.

FOR THE SEA OTTERS OF MONTEREY BAY, THE BUT ONE SEA LION -- FOR ONE SEA LION, THE WORK FIRST THE WASH-UP ESSENTIAL.

FOR BIG MALE IN BIXBY'S GROUP, IT'S TIME TO REARRANGE THE WHISKERS.

BUT AFTER BRUSHING THEIR TEETH IT'S OFF TO BREAKFAST.

THE GROWING OTTER PUPS WAKE UP HUNGRY.

BIXBY WOULD USING 50 MORE ENERGY THAN OTHER SEA OTTERS.

SO SHE'S CONSTANTLY BUT OTTERS ARE FUSSY EATERS.

SOME OPEN WITH A FAVORITE STONE.

WITH A METABOLISM TWICE OF A SIMILAR LAND SIZE MAMMAL OTTERS NEED THEIR DAY.

OTHERS PREFER SEA URCHINS OR AVALONIE.

SHE WRAPS IT'S PLAYPEN THIS LEAVES MOM FREE TO COLLECT SEA BUT BIXBY IS PARTICULARLY PICKY.

SHE LOVES CLAMS.

THEY'RE NOT FOUND IN THE ROCKY FLOOR BENEATH THE KELP.

SO BIXBY HAS TO COMMUTE HALF A MILE TO THE HARBOR TO GET HER SEAFOOD.

SHE MIGHT BE TUCKING INTO HER FAVORITE SNACK.

BUT FOR IS FOOD AND TOO SMALL TO BE ABLE TO DIVE.

THESE WILL JUST HAVE TO WAIT.

-- THESE IMPORTANT LIFE LESSONS WILL JUST HAVE TO WAIT.

YOU KNOW, AN OTTER'S LIFE LOOKS CHALLENGES.

A STUDY CAME OUT THAT HALF THE OTTERS THAT ARE FOUND WASHED UP DEAD ON THE BEACHES, HAVE SHARK BITES.

AND WE HAVE THIS YOUNG OTTER THAT CAME IN WHILE AQUARIUM WAS TAKING A LOOK AT HIM AND HE HAD SOME PRETTY NASTY BITES.

WHILE WE WERE HERE A COUPLE OF OTHER OTTERS HAVE COME HERE JUST FROM THE AREA WITH THESE BITES.

THIS PARTICULAR OTTER IS NAMED THAT'S ITS NAME 711.

DR. MIKE THINKS HE'LL MAKE A FULL RECOVERY AND BE RELEASED IN I THINK THEY'RE AFTER MUCH BIGGER PREY.

BUT A TEST BITE FROM A SHARK ON AN OTTER IS GOING TO PROVE FATAL.

LIZ?

LIZ: THANK YOU SANJAYAN.

LET'S GO TO OUR HELICOPTER.

I CAN CONFIRM, THAT WE HAVE A GREAT WHITE SHARK IN MONTEREY BAY LIVE FOR YOU.

THANK YOU VERY MUCH AARON.

THAT'S EXTRAORDINARY.

IT'S JUST OFF THE BEACH NORTH I'M GOING TO JOIN CHRIS LOWE.

LOOK AT THAT.

WHAT DO YOU MAKE OF THAT?

CHRIS: THAT IS SO COOL.

YOU CAN SEE THE BEACH.

SEE HOW CLOSE IT IS TO THE BEACH?

LIZ: THAT'S SO AMAZING.

I CAN'T BELIEVE HOW CLOSE TO THE THEY'RE EXTRAORDINARY PREDATORS AREN'T THEY?

HOW DO THEY FIND THEIR CHRIS: THEY HAVE A WHOLE SLEW OF SENSORIES TO NAVIGATE AND TO SEE THEIR PREY.

THEY CAN DETECT THEIR PREY UP CLOSE BUT THEY CAN STILL USE IT TO NAVIGATE THE OCEAN.

IT MATCHES THEM AS THIS PERFECT PREDATOR.

LIZ: SEE THESE IMAGES?

>> IT'S A VERY BAD DAY WHEN YOU SEE A SHARK.

IT'S VERY COOL.

ON?

THERE HE IS.

ABOUT TO GO IN.

LOVING THAT.

THERE, ALL OF THE EQUIPMENT IS WORKING WELL.

IT'S GOOD TO SEE HIM GETTING INTO THE DIVE SIGHT.

WE'LL BE GOING BACK TO HIM VERY SHORTLY.

BUT FIRST, CHRIS, IT WAS MY PLEASURE TO JOIN YOU ON A TAGGING MISSION.

TALK US THROUGH WHAT YOU DO ON CHRIS: WELL, OUR GOAL IS TO TRY TO GET A TAG ON A SHARK SO WE THEY GO.

LIZ: OK. CHRIS: WE WANT TO DELVE INTO WHY CERTAIN PLACES AND WHY THEY'RE SO ONE TOOL WE HAVE IS OUR UNDERWATER CAMERAS.

LIZ: I HAD A LOT OF FUN DOING THAT.

LOOK HOW CURIOUS THE SHARKS ARE.

STICK.

CHRIS: THEY WILL EVEN RUB ON THE POLE.

WE CAN SEE ALL THE MARKS SO WE CAN IDENTIFY EACH INDIVIDUAL.

LIZ: YOU CAN BUILD ON YOUR CATALOG, ALL THE GREAT WHITE SHARKS.

COLLEAGUES CONNOR WENT OUT WITH AN EXPERT AND TAGGED A GREAT WHITE.

CHRIS: WE CAN JAB THAT IN.

FOLLOW THEM AROUND AND SEE WHERE THEY GO.

LIZ: NOW FOR THE BIG KAHUNA BECAUSE YOU DEPLOY AN UNDERWATER ROBOT.

CHRIS: WHAT YOU'RE SEEING HERE IS AN UNDERWATER ROBOT THAT'S PROGRAMMED TO FOLLOW THE TAGGED SHARK.

IT THE SHARKS KNOWS THAT IT'S THERE BUT TURNS OFF.

IT CAN MEASURE WATER TEMPERATURE, DEPTH, LIGHT, ALL THE THINGS THAT MAY INFLUENCE WHERE THE SHARK MOVES.

ABOUT CRIST: FOR THE LAST 10 YEARS WE THEY'RE GOING UP.

PROTECTION.

THE NUMBERS HAVE COME BACK BECAUSE THEY'RE BOYFRIEND PROTECTED.

BUT RECENTLY WE HAVE A NEW SET ANSWER QUESTIONS THAT WE HAVEN'T BEEN ABLE TO ANSWER IN THE PAST.

THAT'S THE EXCITING PART.

LIZ: THIS LIVE SHARK, THAT'S A JUVENILE WOULD YOU SAY ON THE SIZE?

CHRIS: BASED ON THE SHOT FROM THE BEACH I WOULD SAY YES.

LIZ: WHY ARE THEY HERE BECAUSE THEY'RE NOT USUALLY THIS NORTH?

CHRIS CLEN THE EL NINO THAT WE'RE HAVING IS BRINGING WARMER WATER.

THE CONDITIONS ARE MIMICING WHAT WE HAVE IN THE NATURAL NURSERY OF SOUTHERN CALIFORNIA.

LIZ: THANK YOU SO MUCH OF THAT MORE WHITES ARE COMING YOUR WAY.

SO DON'T MOVE A MUSCLE.

SEAL.

JOYRIDEENBERG EXPLAINS.

>> GREAT WHITE SHARKS ARE THE MOST FABULOUS BUT MOST FEARSOME OF THE ANIMAL WORLD.

THREE.

THIS ANIMAL, A YEARLYING.

THIS ONE OLDER, A JUVENILE.

ADULT AN YET THIS JAW IS.

BUT THERE ARE DIFFERENCES BETWEEN THESE THREE JAWS FSM YOU LOOK AT THE YOUNG ANIMAL YOU SEE TEETH THAT ARE VERY NEEDLE LIKE.

THESE ARE FOR CATCHING FISH.

KIND OF WHAT YOU'D SEE ON A DOLPHIN BUT AS THEY GET OLDER AND LESS TRY ANGULAR THIS THEIR SHAPE.

WHEN THEY GET OLDER, THEY'RE EVEN WIDER.

THE TEETH ARE SERRATIONS.

BLUBBER OF A SALE.

YOU CAN SEE A VERY LARGE BITE.

THAT BITE WAS MADE BY A GREAT WHITE SHARK.

I CAN TELL THAT BECAUSE IT'S VERY RAGGEDY.

IT'S SORT OF AN AN -- ART SHAPE.

IT'S PRETTY SURVIVED BECAUSE NORMALLY THE STRATEGY IS TO MAKE A LARGE BITE AND RETREAT AND LET THE BLEED TO DEATH AND THEN IT COULD THE TOOTH FAIRY WILL HAVE A VERY HARD TIME.

YOU CAN ZEROS AND ROWS AND ROWS OF TEETH.

THEY WILL REPLACE THE ONES ON THE OUTSIDE AND THEY ROLL OUT LIKE A CON I HAVE ORBELT.

THE ONES THAT YOU SEE IN FRONT THESE ARE THE ONES THAT THEY'RE ACTUALLY USING.

WHY DO YOU NEED TO REPLACE THEM?

THESE TEETH ARE WOBBLY.

INTO BONE.

THEY'RE LYING ON TOP OF SOFT TISSUE ON THE OF CARTILAGE.

THEY'RE FRAGILE AT THEIR BASE.

REPLENISH THOSE TEETH BY ROLLING OUT NEW ONES FROM INSIDE THE IN FACT, 30,000 TEETH IN A SO WHEN YOU LOOK INSIDE THE JAWS OF A SHARK, IT'S EASY TO SEE HOW THEY'VE BECOME APEX PREDATORS.

>> NOW, JOY WAS RIGHT UP HERE ON 2 COAST.

THEY LIKE THOSE EXPOSED COASTS.

I WENT TO GRADUATE SCHOOL HERE AT U.C.

SANTA CRUZ.

THAT'S WHERE AARON IS.

LOOK WHERE OUR GREAT WHITE SHARK IS.

RIGHT THERE.

RIGHT BY WHERE I FIRST LEARNED TO SURF.

NORMALLY THESE SHASHES BE ANYWHERE NEAR THIS AREA.

FIRST OF ALL, I'VE GOT TO ASK YOU.

WHAT DO YOU THINK ABOUT SHARKS?

KATE: KATES ARE AMAZING, THEY'RE BEAUTIFUL.

THEIR SENSES ARE INCREDIBLE.

THEY'RE BEAUTIFUL.

LIZ: THEY'RE MUCH MALIGNED.

LET'S SEE WHAT YOU'VE BEEN SAYING AT HOME.

ON THE FENCE.

LOOK THANK YOU SO MUCH, EVERYBODY.

72% OF YOU ARE SHARK FANS.

16% 12% ARE ON THE FENCE.

OUR MISSION IS TO 12% -- SANJAYAN: SANJAYAN: YOU SAW SOMETHING TRULY SPECTACULAR.

TALK ME THROUGH THIS.

>> I WAS RUNNING MY REGULAR WHALE ONE IS YOUNGER THAN KILLER WHALE CORNERED A YOUNG SANJAYAN: YOU CAN SEE IT.

>> AND THIS SEAL WAS HIDING NEXT TO THE BOAT.

IT WAS TRYING TO GET THE KILLER WHALE BUT EVENTUALLY IT GOT AWAY FROM THE BOAT.

THEY DID GET IT.

THAT'S WHAT THEY DO.

THEY'RE PREDATORS.

EACH ONE OF THESE ABOUT THREE DAY.

SOMETIMES THEY GO AFTER DOLPHINS OR BABY SANJAYAN: WE HAVE A GREAT QUESTION THAT I WANTED YOU TO @LOVEMARINELIFE.

IS THIS TOO CLOSE?

>> >> THERE ARE THREE THINGS THAT PEOPLE NEED TO KEEP IN MIND IF THEY WANT TO YOU NEED TO UNDERSTAND THE YOU NEED TO KNOW YOUR SAFETY AND THE REGULATIONS.

IF PEOPLE ARE THINKING TAKING THEIR OWN BOATS OR KAYAK OR PADDLE BOATS YOU VERSED IN THE SAFETY OF THAT CRAFT.

THEY THEY TO HAVE LIFE JACKETS .

BECAUSE IF YOU DON'T UNDERSTAND THE ANIMAL'S BEHAVIOR YOU DON'T KNOW WHETHER YOU'RE INTERFERING WITH THEM AND REGULATIONS THAT PREVENT HUMANS FROM INTERFERING WITH THEM WHALE WATCHERS ARE VERY CAREFUL.

>> IN THIS CASE THE WHALES CAME TO THE BOAT.

THEY WERE USING THE BOAT THAT TIME.

LIZ: WE ARE USING VERY POWERFUL CAMERAS.

WE ABIDE BY THE RULES AS WELL.

BUT IT'S CERTAINLY GOOD TO MAKE A NOTE OF THAT THANK YOU VERY MUCH FOR THAT, KATE.

DIVER BUT AT THE END OF HE'S NOTHING COMPARED TO A SEA LION.

>> WHAT YOU'RE LOOKING AT HERE SKELETON.

BIG EYE WHY SUCH LARGE EYES?

THEY'RE HUNTING UNDER WATER WHICH MEANS THAT THE LIGHT LEVEL IS PRETTY LOW.

THEY NEED TOE HAVE BIG EYES BECAUSE THAT LETS IN MORE LIGHT.

THESE ANIMALS CAN DIVE INTO 2,000 FEET.

HOW DO THEY STRETCH THAT OUT TO TWO MINUTES.

BY LOWERING THE HEART RATE THEY SLOW THEIR METABOLISM.

IT GOES FROM DOWN TO MINUTE.

DURING THAT TIME THEY'RE ACTUALLY USING LESS ENERGY AND SO THE AIR WILL LAST THEM A LOT LONGER.

THEY STORE A LOT OF MYOGLOBIN.

SO THEY HAVE PLENTY OF OXYGEN IF YOU LOOK AT THEIR RIB CAGE YOU CAN SEE THERE ARE SOME JOINTS WHERE IT CAN FOLD IN.

IT CAN SUCK INWARD.

AS THE SEA LION DIES THE LUNG VOLUME STARTS TO COLLAPSE.

SO THE RIB THAT CHANGE AS THEY GO DOWN.

SEA LIONS SWIM WITH THEIR FRONT FLIPPERS.

IT ACTUALLY LOOKS A LOT LIKE OUR HAND.

IN BETWEEN EACH OF THESE FINGERS IS AND IT USES ITS FRONT LEGS TO PROPEL IT.

WHAT ARE THEY DOING WITH THEIR FRONT FLIPPERS?

ON ALL FOUR WHICH IS ALONG THE WAY ON THE GROUND.

WHEN THEY'RE ON THE WATER THEY CAN TURN THEM BACKWARDS AND USE SO ALL SEA LIONS INCREDIBLE SWIMMERS AND DIVERS BUT PROBABLY THEIR BEST ATTRIBUTE IS THEIR AGILITY.

THAT COMES FROM THESE FRONT FLIPPERS.

THEY CAN AVOID BEING EATEN IN THOSE DANGEROUS WATERS.

LIZ: WELL, DAN COSTA, MARINE MAMMAL SCIENTIST HAS JOINED US.

THANK YOU VERY MUCH FOR JOINING US YOU STUDIED SEA LIONS FOR HOW LONG?

>> OVER 30 YEARS.

LIZ: TELL ME WHAT YOU NOTICED THIS PAST YEAR THAT'S BEEN DIFFERENT.

FEMALES THEAN WE TYPICALLY GET.

BUT THE WARM WATER DOWN SOURNL CALIFORNIA IS PUSHING THESE FEMALES FARTHER TO THE NORTH.

THE CHANNEL ISLANDS.

LIZ: I DID NOTICE YESTERDAY.

THE HAVE THEY TRAVELED A LOT MORE THAN USUAL?

WAY UP HERE TO GET HER FOOD MEANS SPENDING TWO OR THREE SO THE PUPS ARE NOT GETTING ENOUGH FOOD IN MANY CASES IT'S NOT TOUGH TO KEEP THEM ALIVE.

IT'S JUST NOT DOING WELL.

LIZ: THEY JUST DID NOT MANAGE TO BREED AT ALL THIS YEAR.

>> ONE OF THE THINGS THAT HAPPEN BREEDING SEASON OR THEY'LL LOSE A FETUS VERY EARLY ON BECAUSE THERE'S JUST NOT ENOUGH FOOD.

LIZ: WHAT'S CAUSING THIS PROBLEM TO OUR CALIFORNIA SEA LION POPULATION?

>> REALLY RELATED BY THIS WARM WATER.

THE SEA LION POPULATION HAS REBOUNDED IT'S THE HIGHEST IT'S BEEN IN 50 TO YOU HAVE MORE ANIMALS OUT THERE.

AND THEN YOU HAVE THE WARM WATER.

SO YOU HAVE MORE MOUTHS TO FEED AND LIZ: LET'S TAKE A LOOK AT THE CAMERA.

STEVE?

OF THE BREAK WATER.

WE CAME HERE ABOUT AN HOUR AGO AND THE WATER WAS CRYSTAL CLEAR.

BUT IT'S REALLY CHANGED.

IT'S KIND OF LIKE SWIMMING IN I GUESS YOU CAN SEE WHY THE SEA LIONS NEED THOSE EXTRAORDINARY TO FEED AROUND.

IT'S REALLY MURKY.

IT'S AN EXTRAORDINARY PLACE FILLED WITH GORGEOUS COLORFUL STRANGE THESE STRUMS OR BLAZE WHICH GO ALL THE WAY UP TO THE SURFACE ARE THEY GIVE ENERGY THROUGH PHOTOSYNTHESIS AND THEY'RE FOUND -- BOUND IN PLACE DOWN AT THE BOTTOM -- OH, LOOK AT THIS LOOK AT THIS!

THAT'S REALLY COOL!

IT'S A IT GETS ITS NAME -- THE FEATURES ON THE TOP OF HIS HEAD WHICH LOOKS LIKE THE EARS OF A HARE.

BACK UP, TONY.

AMAZING!

ABSOLUTELY AMAZING!

I DON'T KNOW.

MAYBE 10 OF THEM ALL CROSSING ON TOP OF EACH SEA HARES ARE HERMAPHRODITES.

THEY STILL COME TOGETHER TO BREED.

AND YOU CAN SEE THAT FOR SURE HERE THAT LOOKS LIKE SPAGHETTI, THAT'S THEIR EGGS.

THEY'RE VERY MUCH A PART OF THE WEIRD YEAR THE MONTEREY BAY IS HAVING.

THEY SIMPLY SHOULD NOT BE HERE.

AS YOU SEE THEM HERE IN THESE KIND OF NUMBERS IS ABSOLUTELY UNPRECEDENTED.

LOOK AT THAT, THE CLUSTER OF ANIMALS BROUGHT IN BY THESE WARM WATERS.

WHAT MORE EVIDENCE DO YOU NEED OF IS HAVING?

ALL ALONG THE BOTTOM THESE LIKE AN ALIEN ENVIRONMENT.

WE ARE SO CLOSE TO THE AQUARIUM AND YOU CAN FEEL LIKE YOU'RE IN A COMPLETELY DIFFERENT WORLD.

REALLY ATMOSPHERIC DOWN THERE.

THOSE SEA EVIDENCE THAT CONDITIONS ARE DIFFERENT THIS YEAR.

AS WE'VE JUST BEEN TOLD BY DAN, SEA LIONS REALLY STRUGGLED OVER THE PAST YEAR BUT LUCKILY YOU CAN SEE THEM ALL ALONG THE COASTLINE.

JAIME IS RESPONDING TO A REPORT OF A >> WE KNOW THAT THERE'S A SEA LION IN SO IT'S PROBABLY IN STARVATION.

WE DO KNOW A LITTLE BIT MORE ABOUT HIS CONDITION BASED ON HOW HE WAS ACTING.

WHEN WE CAUGHT HIM HE WASN'T VOCALIZING.

HE WASN'T PUTTING UP A STRUG.

HE LET US CATCH HIM.

HEALTHY ANIMAL WOULD BEHAVE.

LIZ: THE SEA LION IS TAKEN BACK TO THE PACIFIC HE'LL BE JOINING 120 OTHER RESCUED PUPS.

THESE THREE ARRIVED JUST TWO DAYS AGO.

AT THREE TIMES THEIR CURRENT WEIGHT.

THEY'VE BEEN CARED FOR BY THE VOLUNTEER, KITTY LONG.

>> WHEN THEY FIRST COME IN WE CAN SEE THEIR RIBS, THEIR HIP BONES AND OUR HEARTBREAKS FOR THEM BECAUSE TIME OUT THERE FINDING FOOD.

OUR JOB IS TO GET THEM FATENED UP.

WE WANT TO SEE THEM GETTING READY TO GO BACK.

>> BEFORE THEY CAN RETURN TO THE WILD THE PUPS MUST PUT ON WEIGHT THEMSELVES.

THEY'RE KEPT IN GROUP TO ENCOURAGE PLAY AND INTERACTION AS WELL THEIR MUSCLES AND HONE THEIR HUNTING AGILITY.

FROM NOW ON, THE VOLUNTEERS MUST PRODUCE CONTACT WITH THE SEA LIONS SO THEY CAN STAY AS WILD AS POSSIBLE.

REHABILITATION, FOUR OF THE STRONGEST SEA LIONS ARE READY TO BE RELEASED TODAY.

♪ >> I DEFINITELY DO GET A LITTLE EMOTIONAL AT EVERY RELEASE I GET TO SEE.

ESPECIALLY THE ONES THAT WERE SO NEAR DEATH WHEN THEY CAME TO US AND NOW THEY'RE GOING BACK HOME.

AND SO IT'S OVERWHELMINGLY REWARDING FEELING TO KNOW THAT I WAS A PART OF THAT.

SANJAYAN: THAT'S A WONDERFUL RELEASE STORY OF A SEA LION.

BUT I CAN'T STOP SMILING RIGHT NOW BECAUSE I'VE GOT TO ADMIT I'M ON THE FUNNEST EXHIBIT OUT HERE AT THE MONTEREY BAY THANK YOU SO MUCH FOR BEING HERE WITH ME.

WHAT ARE WE DOING RIGHT NOW?

WE'RE GIVING THEM SOME FOOD TO KEEP THEM AWAY FROM US.

>> YES, AND TO REINFORCE CERTAIN BAVE BEHAVIORS THAT THEY'RE WE DO A LFT FOUND THINGS FOR THE STANDPOINT.

SANJAYAN: YOU GOT THEM TO DO A VERY IMPORTANT JOB FOR YOU, THE FEMALES.

>> THE AMAZING THING ABOUT THESE FEMALES IS THEY SPONTANEOUSLY DISPLAY MATERNAL BEHAVIOR, BASICALLY ADOPT ONE.

>> THEY'VE THEMSELVES?

THEMSELVES.

THE ADVANTAGE OF THEM BEING ABLE TO FULFILL THAT ROLE FOR US AS THE PUPS GO THROUGH A MUCH MORE NORMAL DEVELOPMENT.

AND IT ALLOWS US TO SUCCESSFULLY THEM INTO THE WILD.

SANJAYAN: SO YOU'RE USING AS IN CLAMS?

IT CAN'T BE CHEAP.

>> NO.

BUT THEY REPRODUCE THE WATER.

PARTICULAR PUP AND THAT'S THE PUP BY THE NAME OF 696.

DUDE, CHECK THAT OUT.

BASICALLY WAS STRANDED.

THESE PUPS ARE FROM A SURVIVAL STANDPOINT.

THEY CAN'T DIVE.

>> YOU HAVE HIM WRAPPED UP IN >> WE HAVE TO STABLE LEEZE THESE ANIMALS FOR SEVERAL WEEKS AND THEN WE LET THE SURROGATE MOTHERS TAKE OVER ONCE THE PUP IS ABOUT 8 WEEKS OLD.

SANJAYAN: AND YOU'RE GOING TO SHOW US HOW YOU GET THESE OTTERS DIE, RIGHT?

SO WHAT YOU'RE GOING TO SEE SOME FOOTAGE OF 696 ON THE EXHIBIT.

WE'RE WE PUT THE SURROGATE MOTHER AND HIM AND THAT GIVES THE PUP THE OPPORTUNITY HOW TO FOLLOW MOM ON DEEPER DIVES.

EVERYTHING A MOTHER DOES.

SORRY THAT IS STILL GOING ON FISHERIES OFF THE CALIFORNIA COAST.

THESE DAYS, INDUSTRY HERE IN BUT A CENTURY AGO, THE FORTUNES OF THIS TOWN IS BEING BUILT ON A COMPLETELY FISHING.

THERE ARE VAST SCHOOLS OF SARDINES, THE VITAL FOOD FOR MAMMAL.
