A Great White Shark Was Attacked by Something Massive — Divers Captured the Aftermath

Added: 2026-05-10

[00:00:00]10 years ago, carcasses of these feared predators began washing up on beaches with their livers missing. Now, it's hard to find any great whites. A great white shark just surfaced off Ela Guadalupe, carrying a scar that should not exist. A perfect ring of puncture marks wrapped all the way around her chest, a circle of teeth wider than any jaw these waters are supposed to hold.

[00:00:23]She is 15 ft long, an apex predator, and something grabbed her like she was bait.

[00:00:28]The bite did not come from a boat. It did not come from a propeller. It came from a mouth. A mouth that does not match any animal in the known catalog of the Pacific. And it is still down there.

[00:00:39]>> The largest great white sharks ever recorded was spotted again off the coast of Hawaii. Now, >> ghost of a megalodon bite. Guadalupe is a rugged volcanic island sitting about 130 m off the coast of Baja California. It is a lonely place surrounded by deep cold water that drops off into shadows very quickly. For people who love the ocean, this is the ultimate spot to see great white sharks in their natural home. These sharks return here every year because the island is like a giant dinner plate filled with elephant seals and sea lions. And every season, a rotation of cage dive operators and freelance underwater photographers anchor over the drop off, waiting in the cold current for the fins to appear. The photographer in the cage that morning has seen hundreds of great whites over the years.

[00:01:31]He knows the rhythm of how they move. He knows the casual rake marks they wear from squid beaks and the crescent scars they pick up from rough seals. This was not that. As she swam past the underwater cages, the divers saw a mark that looked like a giant ring running around her body. This was not a small cut or a scratch from a rough day of hunting. It was a massive circular scar that looked like a giant pair of jaws had tried to crush her entire chest at once. The size of that bite was much larger than the head of any shark those divers had ever seen. And she had survived it. That is the part that stops you. A shark the size of a small car swimming past the cage like nothing happened. Carrying a wound that told a story most people think only happens in movies. When something big enough to eat a 15- foot apex predator takes a practice bite and lets go, your mind starts to drift into some very dark places. Great white sharks are built like tanks. They have been around for millions of years, and they have spent that entire time becoming the perfect hunters. A female shark can grow to be 20 ft long, and she can weigh more than 4,000 lb. Their skin is covered in tiny toothlike scales called dermal dentacles, which make their hide as tough as sandpaper. It takes a serious amount of force to leave a permanent mark on an animal like that. So when the photographs made their way to the marine biologists who studied the Guadalupe population, the first people to really look at the geometry were stumped. The biologist who laid the images out across her desk that afternoon measured the diameter of the ring and then measured it again to make sure she had not made a mistake. The bite was almost perfectly circular. Ramsay and a team of divers were studying tiger sharks off the waters of Aahu, Hawaii on Tuesday when they encountered the enormous predator, >> suggesting a jaw that was wide enough to encircle a huge portion of the shark's body in a single snap. But here is the thing. If you look at the mouth of a typical great white, even a big one, it is usually not that wide. The geometry of the wound just did not match a standard interaction. People keep asking how a shark could survive a hit like that. But these animals are tougher than we can imagine. Their bodies are built around cartilage, which is flexible and heals much faster than bone. Still, the mystery of what actually made that mark began to spread through the scientific community and across the internet like wildfire. We like to think that because we have mapped the moon and sent robots to Mars, we know everything about our own backyard. The truth is that we have only explored about 5% of the deep ocean. Places like Guadalupe Island sit right on the edge of massive underwater canyons that drop down for thousands of feet. These deep trenches are like hidden cities where the rules of the surface do not apply. But we cannot just dive down and look around. The pressure is too high and the darkness is total.

[00:04:22]Which means whatever bit that shark could be living just a few hundred feet below the line where sunlight stops reaching. The ocean is a layered world.

[00:04:31]And sometimes the things from the bottom come up to the top to remind us who really runs the planet. The scar on that great white was not just a wound. It was a message from the deep. And it was telling us that we are not as wellinformed as we think we are.

[00:04:45]Everyone is looking at the shark. But we need to start looking at what is hiding in the dark water beneath her. Before we go any further, if you are the kind of person who gets chills thinking about what might still be swimming in the unexplored parts of the ocean, hit that subscribe button and turn on notifications right now. What we are about to uncover in the next few minutes is going to change the way you look at every shark documentary you have ever watched. Trust me, you do not want to miss the final theory because the last one on the list is the one the researchers stopped talking about on record.

[00:05:18]brutal ocean hierarchies.

[00:05:22]Before we start looking at what is in the water beneath her, we have to understand who she is sharing it with.

[00:05:27]Great white sharks are not the social butterflies of the sea. They are mostly lonely hunters, but when they gather at places like Guadalupe, they have to follow a very strict set of rules. Think of it as a dangerous social club where the biggest individual always gets the best seat at the table. In the world of sharks, size is everything. If a smaller shark gets too close to a bigger shark's meal, the bigger one will give a warning. Usually, this is just a bump or a quick nip to say, "Move out of the way." But sometimes, these warnings turn into full-blown fights. And this is where the geometry stops adding up again. The bite mark on the female shark was far beyond a simple warning. It was an act of extreme aggression. When two sharks fight, they usually aim for the head or the gills because those are the most sensitive spots. This mark was wrapped around the center of her body.

[00:06:15]Something had tried to latch on and hold her still. We often think of sharks as mindless eating machines, but they have complex lives full of territory disputes and quiet power struggles. Cannibalism is a very real thing in the shark world.

[00:06:29]Bigger sharks will eat smaller sharks if they get the chance. It is a great way to pull in a lot of energy without having to chase down a fast seal. But the shark in the photos was not small.

[00:06:39]She was a 15t adult. For another shark to try and eat her, that attacker would have to be absolutely massive. We are talking about a predator that would have to measure 25 or even 30 feet long. Now, officially, the largest great white ever recorded is a female named Deep Blue, who is roughly 20 ft long. If there is a 30ft shark out there, it would be a record-breaker that would change every science book ever written. So, here's the question. Is it possible that there are secret giants living in the deep that never come to the surface? Some scientists think so. They believe that as sharks get older and bigger, they might stop hunting seals near the shore and move into deeper water to hunt other large animals. This would explain why we rarely see them. They would be living in a part of the ocean that we simply cannot reach. There is also the matter of mating because mating can be a very violent process for sharks. Male great whites do not have hands, so they use their teeth to hold on to the females during the act. This often leaves females with scars around their necks and fins, and these are known as mating scars. But when the biologists looked at the circular bite on the Guadalupe female, they ruled out mating almost immediately. Mating scars are usually shallow and messy. This mark was deep, perfectly shaped, and in the wrong place. It looked like a predatory strike, not a romantic one. And the spacing of the tooth marks suggested a jaw much wider than any male shark in the area. Which brings us right back to the same terrifying question. What else is down there? Because if it was not a fight over territory and it was not a mating scar, then someone tried to turn a 15t killing machine into a meal. That is a level of power we are not used to seeing in the modern world. And the only animal in these waters with a confirmed record of turning great whites into meals is not a shark at all.

[00:08:30]Marine survival stories.

[00:08:33]When we think of the ultimate predator, we usually picture the great white. But there is another animal that might actually hold the crown. The orca is the only animal known to regularly hunt and prey upon great white sharks. Orcas are incredibly smart. They hunt in coordinated packs and use teamwork to take down animals much larger than themselves. In South Africa, researchers at the Marine Dynamics team watched for years as a pair of orcas named Port and Starbird began systematically removing the livers from great white sharks along the Gansbai coast. The biologists watched the washed up carcasses come in, each one opened along the pectoral fin, each one missing the oilrich liver and nothing else. The sharks were so terrified by the two orcas that they completely abandoned their hunting grounds for months. an entire population just vanished from waters they had patrolled for decades. So orcas can do it. The question is whether they did this one. When an orca bites a shark, it does not leave a circular ring of shark-like teeth. Orcas have large conicle teeth that leave very different marks. They also tend to rip the shark open to get at the liver which is packed with oil and energy. The mark on the Guadalupe shark was a clean circular bite from a mouth lined with thin razor sharp teeth. Not the heavy peg-like teeth of a whale. On paper, that rules them out on paper. But every few years, a rogue orca pops up somewhere it should not be doing something nobody predicted.

[00:10:02]So, we hold that one in reserve. How fast these sharks can heal from terrible injuries is another piece of the puzzle.

[00:10:09]Sharks have a unique immune system that is actually being studied by doctors to help humans. They almost never get infections, and their skin can close up a wound in a matter of weeks. One famous shark was found with a huge chunk of its back missing after a boat propeller hit it. A year later, the shark was seen again, and the wound was almost completely gone. Exclusive look at the shark the world called Deep Blue.

[00:10:33]Stunning divers swimming right behind him. TJ, >> this resilience is why the female at Guadalupe was still swimming around like nothing had ever happened. But do not let that fool you. A scar like that represents a massive amount of trauma that would have ended the life of almost any other animal. The fact that she survived tells us the initial attack was likely a hit and run. Whatever bit her probably realized she was too big to swallow in one go, and she managed to wiggle free before the predator could finish the job. There are still a lot of rumors in the air about those few seconds under the water, but the evidence points to a single massive strike. People keep asking why we do not see attacks like this more often. The ocean is a very big place and most of it is empty. Predatory encounters are usually very quick. A great white can swim at over 35 mph when it is attacking. If two giants meet in the dark, the fight is over before anyone even knows it started. The only reason we know about this one is because the shark happened to swim past the camera at the right time and the divers in that cage were the only witnesses. which makes you wonder how many other sharks are gliding around the planet right now carrying scars just like this one with no cage, no camera, no record. One of the most overlooked aspects of marine biology is that we only see the survivors. We do not see the sharks that did not get away. If a 15t adult can be bitten like this, imagine what happens to the smaller ones. They probably disappear into the dark and are never seen again. This realization shifts the way we look at the ocean from a place of beauty to a place of constant hidden danger. And once you start looking at the shape of that ring of teeth, the theories stop being ordinary. They start going prehistoric.

[00:12:17]Unexplained ocean sightings.

[00:12:21]If you ask a group of shark fans what could leave a meter wide bite mark, many of them will say the same name.

[00:12:26]Megalodon. This was a shark that lived millions of years ago and grew to be over 50 ft long. Its teeth were the size of human hands, and its jaw was large enough to swallow a whole car.

[00:12:37]Officially, science says the megalodon went extinct about 3 and 12 million years ago when the oceans cooled and their food supply moved away. But a huge community of people believe that a small number of these giants might still be alive in the deepest parts of the sea.

[00:12:52]They point to the fact that we have pulled up fresh looking megalodon teeth from the ocean floor, though scientists say those teeth are just well preserved by the cold. The bite mark on the great white at Guadalupe Island is exactly the kind of evidence these people have been waiting for. They argue that a circular bite of that size is a perfect match for the jaw structure of a young or small megalodon. And then there is the story from the coast of Australia in 2014, which is the one that still makes researchers uncomfortable. The scene is a research lab. A marine biologist is tracking a 9- ft great white shark they had tagged a few months earlier, watching the data trickle in on a screen. Everything is normal. Then the depth reading starts to plunge 200 ft, 500, 1,000, nearly 2,000 ft. She leans closer and then the temperature on the tag spikes from 46° to nearly 80. She just stared at the screen because a great white's internal temperature is not that high. Something had swallowed the shark. Something warm. Something much bigger than anything on the map.

[00:13:56]The only things in the ocean that warm are mammals like whales or a much, much larger shark. The tag stayed inside the predator for days before it was finally released. When it washed up on shore, people began to wonder if a massive unknown predator had swallowed a 9- ft shark hole. That story joined the Guadalupe mystery as part of a growing list of incidents that suggest there is something huge and hungry living in the abyss. Nobody expected this to happen, but the data does not lie. Something big is out there. The idea is that these giant sharks could be living in the ba hypalagic zone, which is the layer of the ocean between 3,000 and 13,000 ft deep. Down there, the water is freezing, and the pressure is intense. Most animals that live there are small and glowing, but there are also giants like the colossal squid. If a giant squid can live down there, why could a giant shark not do the same? Sharks need a lot of food to maintain their body heat and energy, and there is not much to eat in the deep desert of the ocean. However, some researchers think these monsters might spend most of their time in a low energy state, waiting for a big meal to sink down from the surface. Or perhaps they follow the great whites during their migrations, picking them off when they drift far from land. Many are not seeing the truth here because they want to believe in monsters. But the scientific explanations are just as unsettling. A 25- foot great white is just as terrifying as a megalodon when you were the one in the water with it.

[00:15:22]The mystery of this bite mark might not be about what we found at all. It might be about what we are still missing. And once you sit with that thought long enough, the theories start getting stranger. Not less scientific, just stranger.

[00:15:37]Eternal mystery of the shark.

[00:15:40]Here is where it gets weird. And I want you to stay with me because I am not going to pretend any of this is neat or settled. The bite mark on that shark is a reminder that we are just guests in the ocean. We like to think we are at the top of the food chain. But the second we dip our toes into salt water, we enter a world where the rules are written by animals that have not changed in millions of years. The ocean is the last great frontier on our planet. It is a place where legends can still be true and where monsters might actually be hiding in the shadows. Whether the mark came from a record-breaking great white, a rogue orca, or something that should have been extinct, the result is the same. It fills us with a sense of wonder and a healthy dose of fear. A lot of people want a clean answer. But maybe the mystery is part of what keeps the ocean so special. If we knew everything, the sea would not be as magical as it is today. And here is the thing. As our climate changes and the oceans get warmer, these big predators are starting to shift their behavior. Sharks are showing up in places they have never been spotted before. They are hunting in new ways. The shark at Guadalupe might be the first of many to show us that the hierarchy of the ocean is quietly shifting. With better cameras, deeper diving drones, and new tracking technology, we are closer than ever to catching a glimpse of whatever left that mark. But until we pull up clear footage of the attacker, all we have is a scar and a story. And the divers who were in the cage that morning still talk about it because something about the way she moved past them slow and unbothered told them she had already survived the worst thing this ocean had to offer and she was still swimming. So here are the theories not in order of likelihood in order of how much they mess with you.

[00:17:19]Start with the giant squid. We know that sperm whales dive deep to battle colossal squid but we rarely consider how sharks fit into that vertical ecosystem. Great whites are diving deeper into the twilight zone, searching for cooler, oxygenrich water as surface waters warm. Down there, they might be encountering things that usually never see the sun. Imagine a sephalopod with a beak the size of a tractor tire. A defensive strike from a giant or colossal squid could easily leave a mark that looks like a bite to the untrained eye. Especially if the suction cups, which are lined with serrated teeth, clamp down on the shark's flank, not a predator. a panic response from something that did not want to be eaten.

[00:18:02]This is not fish eating fish anymore.

[00:18:04]This is a clash between two entirely different branches of evolution that have been separated by thousands of feet of water for eons. Now, climb up a level because there is a worse possibility. We already know that the deeper animals live, the bigger they tend to get. We see it in isopods. We see it in squid.

[00:18:23]So, what if there is a subspecies of the Greenland shark or the Pacific sleeper shark that has reached unprecedented sizes in the deep trenches off the coast of Mexico? These sharks are slowmoving scavengers by reputation. But they are also opportunistic. If a great white wandered into the territory of a 30foot sleeper shark, the result would be a one-sided struggle. And the sleeper shark would not need to be fast. It would just need to be patient. It would wait for the great white to slow down in the cold, low oxygen water. Then it would strike with a vacuum-like suction and a crushing bite. A slow ghost already living, already documented as a species, just bigger than anyone has ever measured. And then there is the last one, the one that is the hardest to shake. Every few generations, nature produces an outlier. Just as humans sometimes produce individuals who are 7 and 1/2 ft tall, the ocean could be home to super sharks that are simply genetic anomalies, not a new species, not a living fossil, just one shark somewhere out there, a single individual that never stopped growing, maybe from a hormonal imbalance, maybe from a lifetime of high calorie prey like elephant seals. This alpha would be a ghost moving through the water with the same stealth as its smaller kin, but with a level of power that makes a standard great white look like a bait fish. No breeding population to track.

[00:19:47]No bones washing up on the beach. Just one animal somewhere in a canyon we have not mapped. Eating things that do not have a chance. One. That is all it would take. So next time you look at a photo of a great white shark, do not just look at its teeth. Look at its skin. Look for the stories written in the scars. Those marks tell us about the battles fought in the dark and the giants that may still roam the deep. Everyone is obsessed with the sharks we can see. But the real mystery is the one we cannot.

[00:20:16]We are still learning, still wondering, still waiting for the day when the deep sea finally gives up its biggest secret.

[00:20:23]Until then, we will keep watching the water, knowing that something out there is watching back. It makes you wonder if we are really the ones doing the studying or if the ocean is simply letting us see what it wants us to see.

[00:20:35]We have only mapped about 5% of the ocean floor with any real detail. That leaves 95% of the planet as a potential hiding spot for things that should not exist. There are still many rumors in the air, but the one thing we can confirm is that the ocean still has the power to shock us. Whether it is a living fossil or a new nightmare evolved for a changing world, the message is clear. The deep does not answer to us.

[00:21:00]So now I want to hear from you. Do you believe a prehistoric giant like the megalodon is still hiding in the deepest ocean canyons?
