>> AND THAT'S GOING TO BE VERY HARD FOR HER TO SAY IT WASN'T A DRUG. ALL RIGHT, BRIAN, THANK YOU. >> MY PLEASURE. AND NOW TO THE RARE WILDLIFE MOMENT CAUGHT ON CAMERA. WATCH THIS VIDEO OF AN ORCA TAKING DOWN A GREAT WHITE SHARK. SCIENTISTS BELIEVE. IT'S THE FIRST TIME A SINGLE ORCA WAS RECORDED KILLING ONE OF THE OCEAN'S MOST FEARED PREDATORS. JANAI NORMAN HAS THAT STORY. >> IT'S THE JAW DROPPING OF JAWS, A GREAT WHITE SHARK GOING FROM PREDATOR TO PREY. >> THAT'S SOPHIA, A 60 YEAR OLD GRANDMOTHER, ORCA, AN INCREDIBLY RARE FOOTAGE SHOWING EXACTLY WHY THEY'RE CALLED KILLER WHALES. THEIR NAME IS PERFECT, PART OF THE NAT GEO LIMITED SERIES QUEENS. >> ORCA ARE VERY SMART ANIMALS . THEY'RE VERY POWERFUL AND IN SOME CASES, PROBABLY EVEN MORE POWERFUL THAN A WHITE SHARK. I THINK WHAT WE'RE SEEING IS IS PROBABLY AN ANOMALY. >> WE OFTEN THINK OF WHITE SHARKS AS BEING THE TOP IN THE OCEAN. >> WHAT ACTUALLY WORK ARE THE MASSIVE ANIMALS THAT CAN GROW TO NEARLY 30 FEET LONG AND WEIGH SOME SIX TONS? ARE ALSO, HIGHLY SOCIAL. >> TYPICALLY LIVING IN HUNTING PODS, WORKING TOGETHER TO CATCH PREY. SCIENTISTS BELIEVE IN ORCA HUNTING AS A LONE WOLF COULD BE AN ADAPTATION IN CAUSED BY CLIMATE CHANGE. >> THIS IS NOT THE FIRST TIME KILLER WHALES HAVE BEEN SEEN GETTING AGGRESSIVE. THE APEX PREDATORS CAPTURED ATTACKING BOATS OFF THE COAST OF PLACES LIKE PORTUGAL AND MOROCCO LAST YEAR, THIS ORCA CAUGHT OFF THE COAST OF GIBRALTAR RIPPING THE RUDDER OFF A CATAMARAN WITH ITS TEETH . >> THAT PROBABLY DOES HAVE SOMETHING TO DO WITH BEHAVIORS AND, HOW THEY INTERACT WITH THESE OBJECTS, WHICH IS VERY DIFFERENT FROM ATTACKING AND KILLING SOMETHING THAT YOU'RE GOING TO GET FOOD OUT OF. >> SO STORIES OF THE AND MYSTIQUE, A WEALTH OF CAPTIVATED AUDIENCES FOR CENTURIES THINK MOBY DICK.
