Orcas, often known as killer whales, successfully hunt and kill a blue whale, demonstrating once again why they are the most dangerous predators in the ocean. Although it is known that killer whales will attack blue whales, John Totterdell and his colleagues are the only people who have ever documented a successful takedown of a blue whale.

You are undoubtedly aware that blue whales are the biggest animals that have ever lived on Earth; in fact, they are larger than any dinosaur that ever existed. They have the potential to reach lengths of up to 30 meters and weigh in excess of 150 tons.
This is a very, very significant thing. For comparison’s sake, a Boeing 737 is around the same length as a blue whale, so that should give you some indication of its magnitude. Adult blue whales have essentially no natural enemies in the water due to their size, power, and speed, making them nearly unassailable.
The only marine mammal that is known to attack blue whales is the orca whale, popularly known as the “killer whale.” The scientific name for the orca whale is Orcinus orca. Blue whales have been known to be the target of coordinated attacks by these pods of killer whales.
- On the other hand, there are just a few scattered instances of orcas actually murdering blue whales.
- Because many blue whales have scars on their bodies caused by the teeth of orcas, we know that orcas interact with blue whales.
- However, it seems likely that blue whales view orcas more as an annoyance than a threat to their survival.

What animal kills whales?
A group of orcas breaks the surface in the Alaskan sound of Frederick. Images courtesy of Ron Sanford and Getty Images Orcas will attack anything in their path, including fish, seabirds, and even sea lions. Now, for the very first time, there is documentary evidence of a pod of orcas savagely assaulting the largest animal on the world, which is an adult blue whale.
Orcas had never been seen attacking a blue whale till scientists watched a sequence of incidents off the southwestern coast of Australia between 2019 and 2021. Previous reports had reported attempted assaults, but no one had ever seen orcas actually chase one. Marine Mammal Science published an article that detailed the three individual hunts that took place.
According to Robert Pitman, a coauthor of the paper and cetacean ecologist at the Oregon State University Marine Mammal Institute, “This is the greatest predation event on the world.” Anna Gibbs of Science News quotes Pitman as saying, “This is the biggest predation event on the planet.” We haven’t seen anything like this since the time when dinosaurs roamed the earth, and possibly not even back then.
- In each assault, the orcas—also called killer whales—relied on strength in numbers.
- According to Laura Geggel of Live Science, the number of orcas that participated in each hunt ranged from fifty to seventy-five, and more than a dozen of the same individuals were present at all three occasions.
- The orcas killed the whales using a variety of strategies, such as hurling themselves at the animal’s blowhole, raking them with their teeth, and, in one particularly gruesome instance, nibbling on a living whale’s tongue.
Pitman tells Live Science that these killer whales cooperate a great deal with one another and that there are a large number of killer whales. That is most likely the reason why they have been so successful in that region. The blue whale is the biggest mammal that has ever lived on this planet.
- They may weigh up to 150 tons.
- The weight of their tongue alone is equivalent to that of an elephant, while the size of their hearts is comparable to that of a golf cart.
- The average length of an adult blue whale is between 70 and 80 feet, however some individuals can grow to be as long as 110 feet.
- This is equivalent to the length of three school buses.
Orcas are very small when compared, measuring around 30 feet in length and weighing an average of six tons. According to John Totterdell, a biologist at the Cetacean Research Centre in Esperance, Australia, who spoke with Science News about the incident, the first reported attack took place in March 2019 on “a really foreboding, awful weather day.” White water and dorsal fins were noticed by Totterdell and his colleagues as they were making their approach to the location where they regularly observe whales and dolphins.
“It took only a few seconds for us to recognize that they were attempting to take down a significant target. Then we came to the shocking realization that it was a blue whale.” The female-led pod of perhaps a dozen orcas were consuming the creature that was 73 feet in length. Rebecca Wellard, who is the author of the study and a researcher at Flinders University as well as the inventor of Project ORCA, told Annie Roth of the New York Times that “Upon approach, we were shocked by what we were seeing.” The skull of the blue whale was exposed, and the animal was missing its dorsal fin.
“Near the conclusion of the encounter, a female animal dove headfirst into the blue’s mouth,” Totterdell adds in a statement. “It is presumed that she was feeding on the tongue.” “After the whale body sank, there were perhaps fifty killer whales in the vicinity dining and sharing around the blue’s meat.” The second attack took place a little over a month after the first one and was carried out only 24 kilometers (14 miles) away from the original location.
- This time, the orcas decided to hunt a smaller blue whale, maybe a youngster, that was almost twice as long as they were.
- The third incident took place two years later in March 2021 and saw orcas attacking a whale that was 46 feet in length.
- In every instance, the pod of orcas would launch a synchronized attack on the whale, which consisted of grasping onto the animal’s fins, flippers, and tail in an effort to slow it down.
After that, the orcas climbed onto the blowhole of the whale in order to tire out the creature and prevent it from breathing. The three incidents took place at the drop-off of the continental shelf, which is an area where migrating blue whales come into contact with a large population of orcas.
- The fact that blue whales are still very uncommon may be one of the reasons why no one has ever witnessed orcas eating on one of these whales.
- The commercial whaling that took place in the 1900s brought the species dangerously close to extinction; as a result, the International Union for the Conservation of Nature now considers it to be in a state of endangered status.
According to an article that was published in 2018 by Rachael Lallensack for Smithsonian, the growing population of blue whales may lead to an increase in the frequency of attacks on the species. Pitman told Live Science that perhaps “we’re now starting to glimpse a little bit of what the earth looked like before humans destroyed most of the huge creatures that swim in the water.” Animals Australia Biology Ecology Oceans Whales are a wild animal.
Can anything hunt blue whales?
How much krill does a blue whale eat?
Are there any animals that prey on blue whales? – There is just one natural predator of blue whales, and that is the killer whale. bekirevren/Shutterstock. com Large pods of killer whales are the only known true predators of blue whales, and these killer whales can exclusively feed on young whales.
- It is common knowledge that blue whales hold the record for being the biggest mammals that have ever lived on earth.
- These mammalian species call the water their home and consume up to 16 tons of food on a daily basis to keep up with their metabolism.
- When these behemoths swim in the waters of the world, they put themselves in danger because of the extreme depths to which they travel.
Orcas are the sole known natural predators of blue whales; yet, people and things connected to humans kill many more blue whales each year than any other species combined.
Are sharks afraid of blue whales?
Killer whales are so feared that even great white sharks avoid them. According to the findings of a recent research, they are so dangerous that even great white sharks appear to be afraid of them.
Who can defeat blue whale?
Orcas Are Capable of Killing and Consuming Blue Whales, According to Recent Scientific Research You may read about orcas and blue whales here: https://www.nytimes.com/2022/01/29/science/orcas-blue-whales.html Trilobites Killer whales are the biggest animals that have ever existed, and recordings made in the waters off the coast of Australia demonstrated that even as adults, they are unable to hide their formidable predatory abilities.
To give credit. Australian Wildlife Journeys is operated by John Daw. Jan.29, 2022 In March of 2019, researchers researching whales in the waters off the southwest coast of Australia happened across a massive show that very few people had ever witnessed before: a pod of orcas savagely assaulting a blue whale.
The powerful beast was encircled by more than a dozen orcas. Because they had already severed its dorsal fin, the animal was unable to outrun the swift and dexterous predators who were pursuing it. The big creature’s blood made the water become a bright crimson color, and there were pieces of its flesh floating all over in the environment.
The researchers watched as an orca managed to squeeze its way inside the blue whale’s mouth and gorge itself on the whale’s tongue. It took the orcas an hour to kill the blue whale, and once they did, around 50 additional orcas showed up to consume the body once it was finished being cooked. Orcas are apex predators that are known to prey on practically every species of large whale, despite the fact that they are related to dolphins and are members of the same family.
They are also known as killer whales. However, they more frequently target young calves rather than people. Orcas were seen killing and devouring a full-grown blue whale for the first first time when this event took place. The attack was the first of three similar incidents that were seen between 2019 and 2021.
- These occurrences, which were documented in an article that was published in the journal Marine Mammal Science the week before last, have put an end to a lengthy argument that had been going on among scientists over whether or not orcas are capable of making a meal out of an adult blue whale.
- According to Robert Pitman, a marine biologist at Oregon State University and one of the authors of the research, the killing of a blue whale by a pod of orcas is “the greatest predation event on Earth, maybe the biggest one since dinosaurs were here.” This statement was made by Pitman.
There has been anecdotal evidence suggesting that orcas are capable of producing a meal out of an adult blue whale for quite some time; however, it wasn’t until 2019 that researchers were able to confirm this through direct observation. The founder and main researcher of Project ORCA, Rebecca Wellard, who was among the researchers that observed the attack in 2019 said, “Upon approach, we were startled by what we were witnessing.” “When you come across a one-of-a-kind occurrence such as this, I believe it takes some time to understand precisely what it is that you are experiencing.” It is possible for blue whales to reach a length of up to 110 feet over their lifetimes; however, the animal that was attacked was only 70 feet long, which led to speculation that it was a juvenile blue whale.
- Blue whales are the biggest mammals that have ever existed.
- However, Dr.
- Wellard and her crew were successful in taking photographs of the blue whale before the orcas tore it to pieces.
- They came to the conclusion that it was an adult pygmy blue whale after analyzing its appearance, as well as the location and time of year when the photograph was taken.
Pygmy blue whales are a subspecies of blue whales that are genetically similar to the largest of the blue whales, but they are significantly smaller and have other distinguishing characteristics. Pygmy blue whales may grow to a maximum length of 79 feet, therefore it’s safe to assume that this specimen was an adult.
According to Erich Hoyt, a research associate with Whale and Dolphin Conservation and the author of “Orca: The Whale Called Killer,” “I suppose that a fully fledged pygmy blue whale might be mistaken for a typical blue whale that was not quite mature.” He did not contribute in any way to the research.
According to Mr. Hoyt, the fact that these orcas were able to hunt this pygmy blue whale effectively offered as strong proof that they could do the same to even the most huge blue whales. Pygmy blue whales are smaller than standard blue whales. He remarked that blue whales are quick, but orcas are faster than blue whales.
The occurrence that Dr. Wellard and her colleagues were able to observe took place in the waters off the shore of Bremer Bay, which is a biologically diverse location that, during certain times of the year, is home to significant populations of orcas, blue whales, and other types of cetaceans. According to Dr.
Wellard, the killer whales that are being studied in the waters off of Bremer Bay are “rewriting the textbook” on what we thought we understood about this species. Photographers on board whale-watching boats in the area have captured images of two further assaults by orcas on blue whales since the one that was recorded in 2019.
Both assaults that were carried out by orcas on adolescent blue whales were organized by more than a dozen of them. Even while researchers have seen orcas carrying the bodies of deceased blue whale calves in the past, such assaults had not before been documented in their entirety from beginning to end.
Even though it is a horrific sight to behold, the killing of blue whales by orcas might be interpreted by researchers as a good indicator for the wellbeing of other whale species in the region. The commercial whaling business came dangerously close to extinguishing blue whales; the fact that there are currently sufficient numbers of blue whales for orcas to hunt suggests that the population may be recovering.

Do polar bears eat whales?
Preferences Regarding Food and Available Resources – Bearded and ringed seals make up the majority of a polar bear’s diet. They also consume harp seals and hooded seals, as well as scavenge on the carcasses of beluga whales, walruses, narwhals, and bowhead whales, depending on where they are located.
What animal eats a shark?
New evidence suggests that orcas are the most dominant species in the ocean, despite the fact that the great white shark is often regarded as the most dangerous predator in the sea.
Who is the king of the ocean?
When you think of top ocean predators, your first thought is generally of sharks. However, killer whales should not be overlooked. I’m specifically talking about great white sharks here. Killer whales, on the other hand, are the ocean’s undisputed monarchs.
- As apex predators, killer whales have no competition from other animals in their natural environment.
- They hunt in groups, very similar to how wolves do, which are also at the top of their food chain.
- We encounter resident killer whales in Victoria the most of the time.
- These whales feed largely on salmon.
Occasionally, though, we come across transient orcas. These whales consume a wide variety of foods, ranging from fish and seals to sharks and even other whales. Consider the following, in the event that you were still on the fence concerning the apex status of the killer whale: Observers of wildlife off the coast of California saw an orca hunt down and kill a great white shark.
Who would win orca or blue whale?
The Orca and the Blue Whale Each Have Their Own Unique Characteristics: The sheer size of a typical blue whale is sufficient to overcome the might of a single orca, let alone a complete pod of orcas. Image credit: slowmotiongli/Shutterstock.com The orca has a number of important advantages over the blue whale, which allows it to emerge victorious from this competition.
- The blue whale dominates the much more diminutive orca when it comes to size considerations.
- Given that the blue whale does not have any teeth, the orca has a significant edge over the blue whale in terms of its ability to defend itself against predators.
- In conclusion, orcas have a significant edge over blue whales when it comes to living in their pods because the majority of blue whales enjoy leading lonely lives.
On the other hand, this does not make it easy to determine who the winner is. Before we decide whether the orca or the blue whale is the victor of this battle, let’s examine all of the evidence more closely.
Do orcas eat sharks?
What do coconuts, self-portraits, and vending machines all have in common? They are responsible for more deaths on an annual basis than sharks are. Despite this, one of the things that people are most terrified of is being attacked by a shark. The great white shark in particular inspires particular dread in a lot of individuals.
However, it has come to our attention that even they have a valid reason to be terrified of something. Orcas, often known as killer whales, hunt great white sharks in South Africa only for the purpose of eating their livers. The shocking occurrence is also captured on camera at this point. Orcas may be seen using a great white shark as a meal in drone footage that was shown during Shark Week on Discovery.
Orcas are considered the top predator in the ocean. Great white sharks are being hunted by orcas in South Africa right now. Dickie Chivell has invested a significant amount of time and effort on developing an underwater Shark House and conducting research on it.
- 📺 On this week’s episode of #SharkWeek, “Shark House” will continue. pic.
- twitter.com/2K2romFAFi — Shark Week (@SharkWeek) July 29, 2022 The shocking clip was initially shown to us on The Daily Beast.
- This is a segment from the television program “Shark House.” A recent research that was highlighted by Live Science found that the population of great white sharks in the Gansbaai region of coastal South Africa has significantly decreased ever since an orca pod began preying on them.
The sharks used to be there throughout the year, but nowadays there are far fewer sightings of them. Tags placed on sharks have revealed that these fish leave the region, sometimes not coming back for several months at a time. There is a possibility that only two male orcas are to blame for the change that has occurred in the entire ecosystem.
- There have been sightings of smaller sharks in the vicinity, the kind that are normally driven away by the larger great whites.
- The researchers are still gathering information, and footage captured by drones such as these will help them better comprehend the behavior.
- Discovery Shark Week will continue on Discovery Channel all the way up through July 31, 2022.
You can also watch it on Prime Video. In addition, there is National Geographic’s SharkFest, which runs for three weeks and features programming that is also accessible on Disney+. In addition to this, it features suspenseful titles like as “Sky Sharks,” which is about how drones are aiding with research initiatives all across the world.

Do orcas eat blue whales?
Off the coast of Australia, a group of orcas was seen killing and consuming the biggest mammal on the world, the blue whale. This took place in the waters surrounding Australia.
Do giant squids eat whales?
Comparing Giant Squid to Sperm Whales Sperm whales are rather calm animals, preferring to spend the most of their time deep below the ocean seeking for food. Giant squids, on the other hand, are known to be aggressive. In spite of the fact that they are ambush predators, giant squid seldom come into touch with humans since they prefer to stay deep underwater.
- The gigantic squid is substantially smaller compared to the sperm whale, which also has much larger teeth.
- Shouldn’t that give them an immediate and significant edge right off the bat? Let’s compare the sperm whale to the giant squid so we can see which animal is more advantageous and which one would come out on top in a battle between the two.
Learn about some of the most important distinctions by consulting the chart that follows.
|Giant Squid||Sperm Whale|
|Size||30 to 40 feet long Up to 600 pounds||60 to 70 feet long Up to 90,000 pounds|
|Habitat||In the Twilight Zone (depths between 1,000 and 2,000 feet) in most oceans||Deep oceans all around the world|
|Teeth||Sharp beak and a tongue covered with tiny, razor-sharp teeth||20 to 26 teeth on each side of lower jaw|
|Diet||Fish , shrimp , other squids||Fish , sharks , skates , squid|
|Predators||Sperm whales , pilot whales, sleeper sharks||Orcas , pilot whales, false killer whales|
|Speed||Estimated up to 25 mph||Bursts of up to 23 mph|
|Hunting Tactics||Seizes with two tentacles and latch on with their suction cups||Uses echolocation to find their prey, then sucks prey in and swallows it whole|
|Lifespan||Around 5 years||Around 70 years|
Are blue whales hunted?
The whale that was on display at the museum passed away just before a surge in commercial whaling around the world. These marine organisms have provided food and a means of subsistence for inland people for a very long time. People would get into little fishing boats and put their lives in danger to hunt some of the biggest creatures on the planet.
- The quick development of a global commercial whaling industry that began in the early 20th century was directly attributable to the rapid growth of technology.
- The valuable rewards that their enormous bodies contained made blue whales a desirable target.
- The whaling vessels that were utilized in the 20th century were capable of capturing even the most evasive whales, and they were equipped with mechanized weaponry such as harpoons that could explode upon impact.
Large ships encircled and murdered whole pods, turning the ocean a bright crimson color with their blood. Because whaling was such a lucrative industry in the early part of the twentieth century, more than 340,000 blue whales were hunted and slaughtered during that time period.
- The International Whaling Commission (IWC) has decided to put an end to the practice of commercial whaling of all whale species, but hunting for the sake of scientific study is still allowed.
- In defiance of the ban, certain nations, notably Norway and Iceland, continue to engage in commercial whale hunting.
Since the whale that belonged to the Museum passed away, the entire population of its species has been devastated by hunting.
