23:02
Andy is already at the location. He is not alone. The enormous bait balls have attracted huge great white sharks, setting the stage for a promising day. I have good news. We just saw two of them about 300 meters away from us. Large, small, medium? Almost as big as your kayak. Okay. We'll take you straight there and see if we can get you in the water. We're going to throw the sharks in, not me. Don't worry, America. We've given Andy a life jacket. It will be fine. Both sharks are adults. One measures 4.2 meters and the other about 15 meters.
Sharks swim in opposite directions. Hey, I've got it in sight. You've got it. Just before 12:00. There it is. Yes, right here. Yes, it's swimming among the algae. Carlos and Alison have followed the great white shark patrolling among the seaweed. Here we go, mate. Good luck. Okay, I'm going to set up my camera equipment here. Look at that background. It's time to get closer. While Andy chases the largest great white shark farther offshore Hello, Carlos. Do you have a drone? There is a lot of brightness. I need to try to get an image now. The shark is behind you.
Actually, he's not far from Andy. No, Andy is right next door. It's coming, it's coming. It's right behind you, right in your camera's view. It's coming straight for you. He's watching you. I see it. I have an image. I feel like I'm going to lose my mind. He approaches the kayak. Andy Casagrande is just a few meters away from a huge great white shark. Be careful in your kayak. We have a huge great white shark right here. I can't say if it's male or female, but it looks like a possible female. With this shot, Andy confirms that the shark is female. And this drone angle next to Andy's 13-foot kayak
confirms that it measures more than 14 feet long. After circling the kayak, the shark suddenly dives from the surface. Where is the shark? The shark has just sunk. It sank into the column of water. Yes, that's it The drone captures an incredible panoramic shot . Ah! Jaws wide open! I can't believe it. And the camera array is capable of recording a closer angle of the breach and the splashdown. I ca n't believe it. Understood. We have it. It's incredible. The 4 hours I spent in this kayak were well worth it Wow! Bull sharks usually spend their days at the bottom of the ocean ambushing prey such as fish, rays, and even other sharks.
Okay, Paul. Let's get those spray cans. Rosie, Rosie. Stop sign. How are the sharks doing now? We made it rain. There are definitely a lot more sharks right now. They are now much higher up in the water column. The rain seems to be attracting the sharks to the surface. Oh, they're moving much faster right now. That is where almost all of the recent attacks occurred. I think bull sharks might associate raindrops on the surface with other fish. They detect the smallest vibrations. They can feel every movement in the water. They can literally see with their eyes closed.
All sharks can do this using their lateral line. A network of sensory organs that allows them to detect movement, pressure changes, and vibrations. So, what this allows them to do is hunt even in the darkest and murkiest waters. no longer shy. They are getting much closer to me. Are they becoming more aggressive? The rain has definitely triggered a more aggressive response. They are faster, bolder, more willing to bite. How many sharks do you have down there, Rosie? I now have at least 12 sharks with me, and it seems there are quite a few more in the depths. I'm going to go see this. Okay, be careful. Stay with Cole. almost twice as strong as on the
surface. Cole, do you read this? And The current not only takes Rosie out of range of the ship's communications We are currently separating completely. But further away from his safety suit. I don't have anything. I have no communication. That current is very strong. They have moved far away from the ship. The current and the waves are making it impossible for Paul and diving instructor Katie Dim to track the divers. I want eyes everywhere looking for Rosie. They are looking for a bright orange inflatable bag called SMB. divers release them to make it easier for observers to locate them when they surface. I have it.
SMB. I have it. Yes. I have the ball there. Yes, there it is. Yes, right there. I have the ball and SMB. Don't take your eyes off him. I have to go. A diver on the surface. Where is Rosie? He has to leave. No. Cole, can we put that drone in the air? While Paul and the team are searching the surface, guys, as soon as you see her, you have to let me know. Safety diver Cole scans the ocean floor for any sign of Rosie. This 8-foot bull shark has an SMB trapped between its teeth.
All divers in the vicinity of Jupiter Inlet. We have a lost diver, possibly injured. 5 miles off the coast of Jupiter, Florida. Joey, do you have anything about the drone? There is Expand your circle, Joey. Look for any movement. Paul de Gelder is searching for his research partner, Rosie Moore, who disappeared during an experiment to measure the aggression levels of the bull shark. Which way is the current going, Kurt? The very difficult to detect things around here, especially in the hollows and at the peaks of the waves. Every minute we do n't find her, it becomes more and more dangerous.
I have something. Yes, I have it. Half a mile, 7:00 to starboard. Come here, Sam. Right here. We've got you, Rosie. We've got you. Very well, hold her hands and come back. Let's put it in. After nearly an hour lost at sea, Rosie is cold and exhausted But otherwise she is unharmed. I was very afraid that you wouldn't be able to find me. It 's very tough today. He was waving, shouting. That full mask, however, is as if it can't produce any sound. Incredible. It's like the worst nightmare, losing a diver. Getting lost at sea has always been one of my biggest fears in life because you look around and there's nothing there. And there's
nothing you can do. Here! You ca n't shout at anyone, you can't ask for help. You're worried about dehydration. Well, I'm glad everyone is okay. I'm glad they have the university. I'm so glad we found them. Arriving. They're coming, Tristan. They're coming. Yes, I see it. Is it falling apart? They are attacking, they are attacking you. A giant male killer whale tests the lure's rudder. Oh, right below us, there. It's great to be able to see underneath. Another one just happened.
Oh, wait. That is the available support. He's coming back. Right there. Wow, he's.Wow, he's showing off. Yes, arriving. Checking the boat. Oh yes, now he's giving it 100%. Oh a couple of times. Oh, yes. Yes, he gave it to her Ranae! He has completely bent the rudder. Oh, wow, they just broke the rudder. Through the glass helmet, the team sees the attack in detail. The orca is not just hitting the rudder. He 's using it as a control point to grab, turn, and bend. That same movement could be used on
a shark's fin. Control the fin and the orca can turn the shark upside down. That can cause tonic immobility. A temporary paralysis that leaves the shark defenseless. This orca was aligning itself at a very specific angle to try to maintain this blind spot position as it approached. It would be almost impossible for the great white shark to detect the approaching orca. The team has found another move in the orca's repertoire. The surprise. And this could have been borrowed from the great white shark itself.
Both predators rely on surprise, but in very different ways. The great white shark positions itself beneath its prey, becoming almost invisible. For a great white shark, attacking a seal on the surface is a matter of stealth, staying close to the ground, completely camouflaged, and then the precision to reach the animal on the surface and strike it in the right spot. It 25 mph. The bite exerts more than 4000 pounds of force. And it happens in less than a second. With a great white shark, it's all or nothing. For the great white shark, surprise is everything. For the orca, they don't need a perfect moment. They have something much more dangerous. A team.
. That's it. The devastating attack by the orcas brings the Sentinel to a complete stop. So, check this out. This is our rudder. It is completely folded. These orcas only demonstrate their power and physicality when they want to. Renault, Renault, Renault, go back to Tristan. Okay, call the rescue boat and have them come and pick him up. And uh, that's all. As you can see, these are the only options I see.
Yes, we're working on it. A rescue boat arrives and attaches itself to the Sentinel. Drag the battered boat back to port. Hey, he doesn't turn around. Don't know. The current has changed, or these sharks have different behaviors. Corey, see what I mean? There's a rather different angle. All the sharks are taking them. They're not getting close enough. Yes, it's as if something is scaring them. I'm going down to the landing platform, I'll try to get a little closer. Be careful down there. Hi Luke, I'm going to locate the shark as it approaches the landing pad.
Okay, the shark is coming from the right, it's coming from the right, it's coming. It's right up there on the left, towards the left. Okay, it's coming to the right, right. Alright, here comes the shark. Oh. Okay, we have another one approaching from the right. Approaching the landing platform. It's right on the landing pad. Left, left, left. Riley, you've got that new shark coming straight for you. It's loaded, brother. It has the label. Riley, you have a new shark coming straight for you. I think it's probably out of the water.
We have a shark coming for him Are you OK? Thank you, brother. Has anyone seen Riley? Up, up, eyes on Riley. There's a shark right there. Friend. I do n't think you realized how close I was. There was a larger one at the back that lunged straight at you as soon as you entered the water. That? Wow, that's not so normal. So it's interesting that you saw it. Is he one of them? Look at the darkness in that eye. It's enormous. That's it. That's It's enormous. Just like the one I saw last year. When I saw it in the water, it looked darker, but here you can see the difference. It is enormous and very dark in color compared to these. I think it's a different animal. We need to try to label them.
Okay, I'm going into the cage. I want to take that picture before she leaves. Yes, I'll put a label on it and get in touch with you. Okay. The new shark is showing some behavior. He's not like the others. He's acting a little strange. Erratic swimming with lowered fins indicates that this darker shark is tense. It's coming. Wait there. Ah, look, they don't seem very comfortable in this strange environment. They look like tuna balls, people. Look at the shark hanging in the background. While the two new sharks keep their distance, the other one seems to be gaining confidence. The new shark is getting a little closer. See, Riley?
Okay, here it comes. It could be a man, they're arriving right now, but then, as quickly as they arrived, they'll leave again. Corey, that 's really frustrating, man. I can see them. There's definitely a big, dark one, but they're hanging too far away from me. I can't get near them. So let's go out. Let's think of a different plan. See you up here. As the day comes to an end, Riley and Corey have successfully installed 12 tags. They have also identified three prime suspects in the Australian attacks, whose unusual coloration and behavior fit with the little-studied phenomenon.
Corey and I have developed the theory that we have a classic resident population versus a transient population. Resident sharks come to this place every summer to plunder the seal colony and try to find a mate. But then there are the transient sharks. They tend to be larger and darker, leading scientists to theorize that they undertake longer and deeper ocean voyages Many animal species change color to match their environment. And some of these sharks we're seeing have that darker tone, which could indicate that they're moving through deeper, darker waters. Great white sharks possess color-changing skin cells called melanocytes, which allow them to lighten or darken their skin tone to blend in with different water conditions,
suggesting that these darker sharks are recent arrivals from deep waters. Animals that reside locally are familiar with their surroundings and are somewhat calmer because of that. Then there are these transient rogues who cross the territory of other animals, and that entails a more aggressive, more opportunistic, and often dangerous mentality. At the end of the day, Corey and I have culprits involved here. And we need to tag them to see who might be involved in the South Australian attacks. I heard you had a shocking encounter with a shark right in these waters. Yes, right in these waters, in the lagoon was my first time snorkeling from a boat since moving here recently, and we were having a great day with my
friends and my 9-year-old son. My friends were in a place. It was 3 or 5 meters away. What I didn't know was that they had seen a grey reef shark coming straight towards me. I looked up and saw the shark coming towards me. Then I felt something in my leg and felt a tremor, like a dog with a toy in its mouth. When I looked again, I no longer saw the shark. I only saw my leg, which was open and bleeding in the water. She was terrified. Not only was I in danger, but I had just endangered everyone around me. It was as if you had spilled your own blood into the water. Exactly. All he knew was that when there is blood in the water, all sharks become bloodthirsty, and he was very afraid that a feeding frenzy would occur.
Well, I started swimming and the whole time I was waiting for them to attack me again. Finally, I reach my friends, they help me back onto the boat and they start driving as fast as they can back to our island. My 9-year-old son crawled up and took my hand. I wanted her to know that everything was going to be okay, but at that moment I thought, "That's it." I really didn't expect to achieve it. And after what seemed like an eternity, we finally docked and I exhaled deeply. There were firefighters, police, ambulances, everyone was there waiting for us and I knew that once I reached them, I would be in good hands, and that's how it was. That must have been terrifying. There are really no words. It's like being afraid and being prey. And I
had never felt so much fear in my entire life. My God. So, how was your recovery? It was kind of like that Oh. My God. Well, I'm very glad to hear that you were able to recover. Luckily, I had an amazing medical team and three surgeries in 4 months and I'm better than ever. Oh. Can I see your leg? Sure, of course. Mhm. Oh, look at that scar. Yes. Wow. You could see the shape of the jaws right there, the marks of the teeth.
Yes. It's not something you expect to see every day. So, has anyone else seen a shark behave like this here before? From what everyone has told me, they haven't seen an unprovoked bite around here that they can all remember. Oh. Everyone was completely shocked. People go diving with sharks every day, they get very close, they touch them, and I wasn't even near the shark, and yet it came for me. So there was no provocation. It was very, very unusual behavior. Oh. People wondered what was happening here to cause something like this, and they were worried that something strange might be going on in these waters.
Based on everything we've learned so far, I agree, and that's what we need to investigate. Well, thank you very much for sharing your story. I'm glad to see that, despite all that trauma, you overcame it. Thank you so much for coming here. Thank you, Jacqueline. Take care of yourself. Now, to find that shark during the coldest time of the year, I 've come to the largest nuclear power plant on the West Coast, Diablo Canyon. That outflow of warm water from that area creates a microhabitat here that I hope these small sharks will occupy, where there are tons and tons of food. So let's go diving here and, hopefully, we'll find a small shark. Let's do it Well, here we are on this rocky
central coast of California. This area with this hot water outlet has just created a spa for animals. It's very foggy and it's a truly unique ecosystem. Now, as you can see, this area is a hedgehog garden and there are purple hedgehogs all over the background. white shark. Oh my God! There's a great white shark circling us down here in this murky, low-visibility water. Hey, I thought he had sneakily approached me from behind. Mike, are you okay? Yes, right here. The shark is behind you. Look at it there. Right there. It's literally circling all around us. It keeps us stuck at the bottom.
This is crazy. Oh, it's swimming at the bottom. Swimming. In California, great white sharks are famous. This is an area called the Red Triangle. Famous for great white shark attacks. We need to stay very close to the rocks and start heading back to the ship. They are everywhere. There are two or three great white sharks, 3.6 to 4.5 meters long, circling us, keeping us immobilized on this reef. This is crazy. And even though we're only 6 meters away, if we leave this reef, the sharks will come straight towards us. Hello, we all stay united. Mike is looking for the shark. I don't know if he. He's watching mine, but that was crazy. I had never been so close to a great white shark before. We're going to have to
run. Are you ready, Mike? Are you OK? Okay, you're in. How long were we in the water? 3 minutes And then we spent the whole dive trying not to get eaten and getting back to the boat. I'm not kidding, I was screaming, but I didn't press the button. And I thought, "Damn!". I pointed at the thing and suddenly it swam right behind me. And I was sending it. It wasn't coming slowly. It came at great speed this time. Like I'm coming straight towards you. Dude, I don't like that. This is closed. It's too dangerous. What a great experience! Oh, there's a great white shark right there.
Look, look, look. That's the one who was chasing us. There are two or three more. That's crazy, dude. Wow! We're fine down here. That was crazy. Lorenzo, a 15-foot shark, may have demonstrated true animal intelligence, seeing past the mirror sharks and targeting the prey. It Yes. Across the line, the mirror line. But in his excitement, he knocked all the equipment out of place. And the chaos is attracting more curious great white sharks. Three sharks. Wow! Oh my God! Oh, oh, oh! Very good, guys. Let's call it a food frenzy, right now.
This is what these great white sharks usually do. Okay, we're just waiting. We're finished. Wasn't it incredible? Incredible. Up close and personal with a group of sharks. The second phase of the mirror test was a great success. I was thinking. I was calculating. He was using his mind. And that's proof of how intelligent they really are. Well, today was exciting because Lorenzo went from treating that reflection as a threat to basically ignoring it. She discovered there was nothing to worry about. That's learning. Reacting very quickly and adapting to new objects in its environment is exactly what you look for in a trainable animal. So now we want to take it a step further. Can we train a great white shark to
do something it would normally avoid? Some signs in the air. This will simulate what happens if they fall into the water outside of their cage. No, wait. That's all. This is going to get ugly. Get ready whenever you want, Jay. Everyone ready. When Molly falls into the water, it will create a shockwave. All sharks in the vicinity will sense it and react immediately. Here we go. Oh my God. It's coming straight towards you. I'm going to the cage. Oh no, the rope is going to break. The sharks are getting nervous. I do n't know what's happening anymore. They're on every corner. He comes straight to the
camera. My God, what else is going to happen to me, man? It's crashing into the cage. Do n't worry. The sharks are going to enter that cage. Unlike many solitary species, Caribbean reef sharks hunt in groups. Oh. Here, more than a dozen sharks have already gathered beneath the cage. As if there was a lot of action down there As more sharks investigate, their movements become faster, tighter, and increasingly unpredictable. And that's why you don't end up outside the cage. Please and thank you. They're going to be everywhere.
Holly is going crazy. Everything will be alright. Everything is fine. Take a deep breath and try to stay calm. We're going to get you out. Hang in there. The great thing about diving with sharks is that it's one of those things you'll remember and talk about for the rest of your life, and nothing else compares. There's nothing in this world I can do like being in the water with sharks. Yes. There were so many. Everywhere I looked, they were there, and so much was happening. I didn't like it. It started to get too much.
I'm proud of you. That's a great first step. Thank you. Friday, August 13. Very, very hot, about 32°C. A good day to be on the boat, get a tan and relax. There were 10 of us on the boat and the plan was to go and see the island. Locals call it Margie Island. Actually, we were the only two girls on the boat. So he convinced me to jump. We swam for about 15 or 20 minutes. Then her boyfriend and mine jumped in too. They swam for a couple of minutes and then we got out. And that's when it happened. It came out from below and then got hooked. I saw black on my leg. And instantly the ocean turned red.
He was shouting that he had caught me, he had already caught me. He had me hooked. There was a lot of pain. The shark hadn't dragged me down. I thought I saw some kind of dorsal fin to my left. It was about 10 feet from the ship. Help me. The girl in the water who was farther away could have been next. He had swum through all the blood. We reached the stairs almost at the same time and I stretched out my arms and my boyfriend and another guy started pulling me up. I simply landed and let myself fall because I couldn't use my legs. Taylor's friends use a belt as a tourniquet to stop the flow of blood. They call 911 and run to the shore, where a medical helicopter takes her to the hospital. Since
Taylor's attack, there have been dozens of close encounters. That thing is enormous. Look, a great white shark. Oh my God, look at this. Then, in the middle of summer, a whale carcass covered in fresh shark bites washes up in a popular kayaking area just outside Lunenburg. Walter Flower, a local whale-watching guide turned shark tracker, is one of the first to arrive on the scene. I thought, "What an opportunity." For the past 5 years, Walter and his daughter, Ali, have been on the front lines. helping to document the shark invasion in Nova Scotia. Good, Ali. We grabbed a pole camera and our phones, hoping to capture the sharks celebrating.
They had some good identification photos. Oh my God! My heart is racing right now. They are in predator mode. By the tail. Whale fat is the most calorie-rich food for hungry great white sharks. They have us in their sights. They've got their eyes on us, Dad. The shark isn't just looking at the whale, it's also looking at us, who are on the pole. He's coming straight for me, man. I'm really scared it'll bite the ship, man. Be prepared to hit the deck if something hits the ship. It's there. I'm turning around. I 'm turning around. It's coming up. Oh my God! My Mother! He just hit us.
Yes. I'm scared, guys. My engine started. My God, look at this thing. He's a fat shark. Oh my God! My life is shaking. Oh my God! The team identifies at least six distinct great white sharks. The two large adults stand out. Sure, look at this. This monster is female. We call her Big Mama. It had a small, red notch on its fin. So we simply called it Red Tip. There's Red Tip coming closer to take a bite. Look at Big Mama right behind you.
Look at that belly. Oh, look at that. Directly. It has so much power. He simply turned the wheel. Mine. I counted six different great white sharks at the same time. It was incredible. . Humiliating. I could be lunch too. Here we go. Nine miles from Malapascua Island, Craig and Aliea release Ursula, an innovative sardine bait system designed to capture the legendary tail strike of the thresher shark. Come on, tail whip. This is. definitely noticeable that the sharks were attracted to Ursula. Ursula is actually doing something. That second shark, when it entered, was in the middle of the water column, at the level of her eyes. With Ursula. Now, a thresher
shark has an elevated body temperature around its eyes and brain, which means it is not only super intelligent, but also has great visual acuity. So, I think what happened in that particular situation is that the shark saw Ursula from a distance. He activated hunting mode, but as he got closer and closer, he realized it wasn't real prey and went on his way. The most amazing thresher shark toy on the planet. When I first got into the water, my ideal vision of success would have been a tail slap over my head straight at Ursula. But, in reality, any interaction between Ursula and a thresher shark is a data point that we can use.
Having a pelagic thresher shark swimming alongside us was one of the most exciting things. It means we are getting closer and closer to triggering that hunting behavior. But that behavior won't be captured without an adjustment to your fox lure. This is probably the most incredible invention of all time. Oh. It is a human-operated towed response inducer called THOR. THOR stands for towed human-operated response inducer. Basically, I hold an underwater scooter and attach this reflective line to my waist. I am a human underwater decoy for sharks. It's pretty incredible. These thresher sharks are visual predators. If you look at these fish here, they are super flashy, super bright. So hopefully, this will be the perfect way to get
these sharks onto the ledge and we can get that perfect shot of a tail slap. When you think of Ursula, Thor is a perfect advancement of that approach because we can strategically place Thor right in front of the thresher shark. I've had many good ideas in my life. This is not one of them. I've never used a scooter underwater. Many things could go wrong. Working with these predators and using all these different types of technology is incredibly dangerous. If these animals go into hunting mode, accelerate, and hit us from the wrong side, we could be left unconscious underwater. Just be careful with my back down there. I've got you covered. Don't worry. As the day progresses, the thresher sharks are likely to
head to deeper waters. The team returns to the drop-off near the Kimud sandbank, hoping that the same sharks that reacted to Ursula are still nearby. We have the scooter and Thor in hand. It's time to go, Craig. Pull the trigger and launch. The team attaches a sardine lure to Craig's waist, creating a moving miniature bait ball designed to attract the attention of a hunting thresher shark. Okay. Thor is ready. Here we go. In 3, 2, 1, takeoff. It's been great. Like a school of sardines. Copied. I am going to replicate our struggle movement.
Jack, Jack, Jack. Jack, do you copy? A thresher shark is electrocuting Thor. It's hot on your heels. What's that? Wow, a thresher shark. You know what to do, Thor. It's working. He's heading straight for Thor. Picking up speed. It's right above. This could be our opportunity. has blocked the entrance. Oh, he's retiring.
