Killer whales attack and sink sailing yacht in the Strait of Gibraltar — again

A sailing yacht sunk in the Strait of Gibraltar on Sunday after an unknown number of orcas  slammed into the vessel with two people on board and caused a water leak, officials said. Both crew members were rescued by a passing oil tanker, said Spain's maritime rescue service, marking the latest killer whale attack on a boat in what has become a pattern in recent years.

The incident happened at around 9 a.m. local time in the narrow strait between Spain and Morocco that has become a notorious site of human interactions with pods of killer whales that, for reasons still not fully understood, ram into boats and at times even sink them . In this case, crew members on board the SV Alboran Cognac yacht put out an emergency call for an evacuation after they encountered orcas roughly 14 miles off the coast of Cape Spartel. 

The crew members reported feeling blows to the hull of the vessel and rudder, which was damaged by the whales, the rescue service said. The agency's coordination center in Tarifa, on the Spanish side of the Strait of Gibraltar, helped arrange for their evacuation via the tanker MT Lascaux. The tanker was able to collect the crew members from the sinking yacht within the hour, and they disembarked in Gibraltar before 10:30 a.m. They abandoned the SV Alboran Cognac, which proceeded to completely disappear into the ocean.

Anyone sailing through waters from the Gulf of Cádiz in southern Spain and the Strait of Gibraltar, either in a larger motorized vessel or a personal sailing boat, is advised to avoid certain areas that the maritime rescue service marks as potentially dangerous spots for orca interactions. The greatest threats exist between May and August, when officials say that pods of killer whales are most commonly seen in those parts of the Atlantic. 

But previously recorded incidents suggest those dangers may be present at any time. Last October, a Polish boat touring company reported that a pod of orcas had managed to sink one of its yachts after repeatedly slamming into the steering fin for 45 minutes, causing it to leak. Last June, two sailing teams competing in an international race around the world reported frightening scenarios in which multiple orcas rammed into or pushed up against their boats or as they sailed west of Gibraltar. 

No one on board any of the vessels was hurt in those encounters, but the documented rise in confrontational behavior has researchers and sailors trying to determine why orcase have attempted to sink or capsize so many boats off the coasts of Spain and Portugal. 

Some sailors have even resorted to blasting thrash metal music in a bid to deter the apex predators.

Reports of orcas interacting with humans have more than tripled in the last two years or so, according to the research group GTOA, which has documented hundreds of such incidents in the region since 2020. But some of the latest data points to possible changes in the orcas' etiquette, with the group reporting only 26 interactions in the Strait of Gibraltar and Bay of Biscay areas between January and May of this year. That number is 65% lower than the number of interactions recorded in the region over the same months last year, and 40% lower than the average number of interactions recorded in the same months between 2021 and 2023, according to GTOA.

For 45 minutes, the crew of the Grazie Mamma felt like they were under attack from below. A pod of orcas had zeroed in on the yacht's rudder as it made its way through the Strait of Gibraltar last week, and rammed it repeatedly, "causing major damage and leakage," according to the company that operated the boat.

Rescuers were able to save the crew and return them safely to port in Tanger-Med on the coast of Morocco. Their vessel, though, sank into the sea.

"This yacht was the most wonderful thing in maritime sailing for all of us," read a statement posted to Facebook by Morskie Mile , the Warsaw-based touring company that operated the boat. "Very good memories will be transferred to Grazie Mamma II. Love of the sea always wins and friendships remain with us."

The company said it is working to ensure its upcoming trips to the Canary Islands go on without a hitch.

Last week's incident was the latest in a string of recent "attacks" by orcas in the waters separating southern Europe and northern Africa — encounters that have left researchers scratching their heads.

Killer whales are 'attacking' sailboats near Europe's coast. Scientists don't know why

Since 2020, there have been about 500 encounters between orcas and boats, Alfredo López Fernandez, a coauthor of a 2022 study in the journal Marine Mammal Science, told NPR earlier this year. At least three boats have sunk, though there is no record of an orca killing a human in the wild.

Scientists have been trying to pinpoint the cause of the behavior.

One theory among researchers is they're just playing around. Other researchers say it may be that the whales like the feel of the rudder.

"What we think is that they're asking to have the propeller in the face," said Renaud de Stephanis, president and coordinator at CIRCE Conservación Information and Research in Spain, in an interview with NPR last year. When they encounter a sailboat without its engine on, "they get kind of frustrated and that's why they break the rudder," de Stephanis said.

Another theory is that the behavior may be some sort of act of revenge due to possibly traumatic , previous encounters with fishing boats.

Revenge of the killer whales? Recent boat attacks might be driven by trauma

"I definitely think orcas are capable of complex emotions like revenge," Monika Wieland Shields, director of the Orca Behavior Institute previously told NPR. Shields said she does not think "we can completely rule it out," even if she was not entirely convinced herself.

Deborah Giles, the science and research director at conservation group Wild Orca, says pods in other areas, such as near Washington state, have been targeted by humans, but haven't shown a pattern of ramming boats.

Which underscores why researchers say it's difficult to draw any conclusions from the interactions documented to date. In an open letter published this summer, 30 scientists cautioned against "projecting narratives onto these animals," writing that "In the absence of further evidence, people should not assume they understand the animals' motivations."

An earlier version of this story misstated the yacht's name, Grazie Mamma, as Grazie Mamma II.

Why are orcas attacking boats and sometimes sinking them?

After four years and hundreds of incidents, researchers remain puzzled why orcas, also known as killer whales, continue to ram boats – sinking a few of them – along the Iberian Peninsula. The most-recent incident was the sinking of a yacht on Oct. 31 in the Strait of Gibraltar.

The origin of these interactions remain a "great mystery," said Alfredo López, a University of Santiago biologist, but he does not believe the behavior is aggressive. Orcas are large dolphins, López said. And like dolphins, the events could stem from the orcas’ curious and playful behavior, such as trying to race the boats.

López, who specializes in orcas, and his team, Grupo de trabajo Orca Atlántica (GOTA) , have tracked these encounters since 2020. The team’s recent study theorizes the orcas could also be exhibiting cautionary behavior because of some previous traumatic incident.

Where have killer whales interacted with boats?

GOTA has tracked more than 350 interactions just on the Iberian Peninsula since 2020. Most have taken place along the Strait of Gibraltar, but the orcas’ mischief or self-defense may be spreading north. An incident was reported in June in the  Shetland Islands in Scotland .

GOTA defines interactions as instances when orcas react to the presence of approaching boats, such as:

• Interaction without physical contact.
• Some physical contact without damage.
• Contact that causes serious damage that could prevent the navigation of the boat.

Recent incidents when orcas attacked boats and sank them

The Oct. 31 incident occurred in the Strait of Gibraltar where a pod of orcas sank a mid-size sailing yacht named the Grazie Mamma after a 45-minute interaction,  Live Science reported . 

On June 19 an orca rammed a 7-ton yacht multiple times off the Shetland Islands in Scotland, according to an account from retired Dutch physicist Dr. Wim Rutten in the Guardian.

"Killer whales are capable of traveling large distances, so it is not out of the ordinary that an animal could travel that far," said Tara Stevens, a marine scientist at CSA Ocean Sciences Inc. "To my knowledge, this data is not available, so we cannot confirm at this time if these are the same animals." 

Including the Oct. 31 incident, orcas have sunk four boats this year. The previous sinking occured in May , off the coasts of Portugal and Spain, but whale expert Anne Gordon told USA TODAY  in May that the incidents shouldn't heighten concerns about the whales.

"Yes, they're killer whales. And yes, their job is to be predators in the ocean, but in normal circumstances there is absolutely zero threat to humans in a boat," Gordon said .

Most of the interactions have involved sailboats, but fishing boats, semi-rigid boats and motorboats haven’t gone unscathed. 

Are these the same killer whales attacking boats or unrelated incidents?

López hypothesizes that the interactions could be a self-induced behavior where you're "inventing something new and repeat it. This behavior coincides with the profile of the juveniles." He said it could also be response to an aversive situation: "One or several individuals had lived a bad experience and tried to stop the boat so as not to repeat it. This behavior coincides with the profile of adults."

"Fifteen different orcas from at least three different communities" have been identified, López said. And they are probably teaching the habit to others, or the others are mimicking the behavior. "Without a doubt orcas learn by imitation," López said.  The majority of the culprits are juveniles that touch, push and sometimes turn the vessels. He noted that adult males don't appear to be involved.

"Killer whales are incredibly intelligent animals that do learn behaviors from observation of other individuals," Stevens said. "Typically, very unique behaviors such as this are learned 'within' group, meaning individuals of the group may learn from each other and participate, but that does not necessarily mean that the behavior is shared outside the group with other individuals."

Which pods of killer whales are battering the boats?

Orcas operate in a social structure called a pod. These pods generally are a group of several generations of related orcas. Hierarchies are established within them, and they communicate and learn from one another, the study reads.

GOTA researchers have identified the individuals responsible for the interactions . One large pod is made up of three generations. It starts with grandmother Gladis Lamari, her daughter, grandchildren and a few other relatives.

Another pod comprises siblings Gladis Negra and Gladis Peque. Both have been photographed interacting with boats. Their mother, Gladis Herbille, has generally just watched her children at a distance from the boats, the study said.

A third group in the study are siblings and a cousin.

Orcas often tracking bluefin tuna

The movements of orcas depend on the location of their main food source, bluefin tuna. The migratory movements of tuna are very dynamic and predicting exactly where interactions will take place is very difficult, the report said. According to NOAA , Atlantic bluefin tuna are the largest in the tuna family and can reach a length of 13 feet and up to 2,000 pounds. They are a highly migratory species and can migrate thousands of miles across an entire ocean.

About the Iberian orcas

While they are called killer whales, orcas are actually the largest member of the dolphin family. This aquatic marine mammal family includes whales, dolphins and porpoises.

The Iberian orca is a subpopulation of the Atlantic orca population. These orcas are from the Strait of Gibraltar and the Gulf of Cádiz. Iberian orcas are small: 16 to 21 feet compared with Atlantic orcas that measure almost 30 feet.

Orcas in general are fast, reaching speeds up to 27.6 mph. By comparison, a 39-foot sailboat travels at about 9.2 mph.

What should you do if your boat is attacked by killer whales

The study recommended these tips to reduce the duration and intensity of the interaction.

• Stop the boat.
• Leave the rudder loose.
• Radio for help.

According to the GOTA study, most of the vessels involved in interactions are medium-sized (less than 49 feet) sailboats, with a paddle rudder, sailing at an average of 6.9 mph, under both sail and motor.

The interactions have been mostly concentrated in the spring and summer months and have been concentrated in the midday hours. They've lasted on average for 40 minutes, but several last less than 30 minutes. 

Types of rudders Iberian orcas have approached

"It is very common for dolphins to interact with the boats and approach," López said. "Before 2020, the orcas did it with frequency but they weren't classified as attacks. Now, sometimes they touch the boat and the encounter is unfairly classified as an attack. They judge socially before understanding what (orcas) do."

Orcas sank three boats off the coast of Portugal, but don't call them 'killer' just yet

Three recent incidents of orcas seemingly attacking and sinking boats off the southwestern tip of Europe are drawing intense scrutiny over whether the animals deliberately swarmed the vessels and if they are learning the aggressive behavior from one another.

Encounters between orcas, or killer whales, and boats have been increasing since 2020, though no human injuries or deaths have been reported. In most cases, the whales have not sunk the boats.

The string of incidents since 2020 prompted one scientist in Portugal to say the attacks may indicate that the whales are intending to cause damage to sailing vessels. Others, however, are more skeptical, saying that while the behavior may be coordinated, it’s not necessarily coordinated aggression.

“I think it gets taken as aggression because it’s causing damage, but I don’t think we can say that the motivation is aggressive necessarily,” said Monika Wieland Shields, director of the Orca Behavior Institute, a nonprofit research organization based in Washington state.

At least 15 interactions between orcas and boats off the Iberian coast were reported in 2020, according to a study published last June in the journal Marine Mammal Science .

In November 2020, Portugal’s National Maritime Authority issued a statement alerting sailors about “curious behavior” among juvenile killer whales. The statement said the whales may be attracted to rudders and propellers and may try to approach boats.

The subsequent sinkings have caused more alarm.

The most recent encounter occurred on May 4 off the coast of Spain. Three orcas struck the rudder and side of a sailing yacht, causing it to eventually sink, as was reported earlier this month in a German publication called Yacht .

One theory put forward by Alfredo López Fernandez, a biologist at the University of Aveiro in Portugal, suggested that the aggression started from a female orca that was perhaps struck by a boat — a traumatic experience that caused her to start ramming sailing vessels. López Fernandez, who co-authored the June 2022 study published in Marine Mammal Science, told Live Science that other orcas may have then picked up that behavior through social learning, which whales have been known to exhibit.

But Shields said orcas have not historically been known to be aggressive toward humans, even when they were being hunted and placed in captivity.

“They’ve certainly had reason to engage in that kind of behavior,” she said. “There are places where they are shot at by fishermen, they’ve watched family members be taken from their groups into captivity in the ‘60s and ‘70s. And if something was going to motivate direct aggression, I would think something like that would have done it.”

Shields added that there are no clear instances of killer whales exhibiting what could be thought of as revenge behavior against humans.

She said the recent attacks on boats are likely more consistent with what’s known as “fad” behavior, which describes novel but temporary conduct from one whale that can be mimicked by others.

“It’s kind of a new behavior or game that one whale seems to come up with, and it seems to spread throughout the population — sometimes for a matter of weeks or months, or in some cases years — but then in a lot of cases it just goes away,” she said.

In the Pacific Northwest, for instance, Shields and her colleagues have observed fad behavior among Southern Resident killer whales who started carrying dead salmon around on their heads for a time before the behavior suddenly stopped.

Shields said the behavior of orcas off the Iberian coast may also be temporary.

“This feels like the same type of thing, where one whale played with a rudder and said: ‘Hey, this is a fun game. Do you want to try it?’ And it’s the current fad for that population of orcas,” she said.

While Shields did not dismiss the trauma response theory out of hand, she said it would be difficult to confirm without more direct evidence.

“We know their brains are wired to have really complex emotions, and so I think they could be capable of something like anger or revenge,” she said. “But again, it’s just not something that we’ve seen any examples of, and we’ve given them plenty of opportunities throughout the world to want to take revenge on us for various things. And they just choose not to.”

Orcas disrupt boat race near Spain in latest display of dangerous, puzzling behavior

A pod of killer whales bumped one of the boats in an endurance sailing race as it approached the Strait of Gibraltar, the latest encounter in what researchers say is a growing trend of sometimes-aggressive interactions with Iberian orcas.

The 15-minute run-in with at least three of the giant mammals forced the crew competing in The Ocean Race on Thursday to drop its sails and raise a clatter in an attempt to scare the approaching orcas off. No one was injured, but Team JAJO skipper Jelmer van Beek said in a video posted on The Ocean Race website that it was “a scary moment.”

“Twenty minutes ago, we got hit by some orcas,” he said in the video. “Three orcas came straight at us and started hitting the rudders. Impressive to see the orcas, beautiful animals, but also a dangerous moment for us as a team.”

Team JAJO was approaching the mouth of the Mediterranean Sea on a leg from the Netherlands to Italy when at least three orcas approached the VO65 class sloop. Video taken by the crew showed one of the killer whales appeared to be nuzzling the rudder; another video showed one of them running its nose into the hull.

Scientists have noted increasing reports of orcas, which average from 16-21 feet (5-6½ meters) and weigh more than 8,000 pounds (3,600 kilograms), bumping or damaging boats off the western coast of the Iberian Peninsula in the past four years.

The behavior defies easy explanation. A team of marine life researchers who study killer whales off Spain and Portugal has identified 15 individual orcas involved in the encounters — 13 of them young, supporting the hypothesis that they are playing. The fact that two are adults could support the competing and more sensational theory that they are responding to some traumatic event with a boat.

The sailors were warned of the hazard.

“We knew that there was a possibility of an orca attack this leg,” Team JAJO on-board reporter Brend Schuil said. “So we had already spoken about what to do if the situation would occur.”

Schuil said there was a call for all hands on deck and the sails were dropped to slow the boat from a racing speed of 12 knots. The crew made noises to scare the orcas off, but not before it had fallen from second to fourth on the leg from The Hague to Genoa, where it is expected to arrive this weekend.

“They seemed more aggressive/playful when we were sailing at speed. Once we slowed down they also started to be less aggressive in their attacks,” he said. “Everyone is OK on board and the animals are also OK.”

The Ocean Race involves two classes of sailboats at sea for weeks at a time, with the IMOCA 60 boats competing in a six-month, 32,000-nautical mile (37,000-mile, 59,000-km) circumnavigation of the globe. Boats have already contended with a giant seaweed flotilla , catastrophic equipment failure, and a collision that knocked the leader out of the decisive seventh leg.

Although the race course navigates around exclusion zones to protect known marine habitats, there have been previous encounters with whales in The Ocean Race and other high-speed regattas.

However, they usually involve the boats crashing into the animals, and not the other way around.

One of the boats in the around-the-world portion of this year’s Ocean Race triggered its hazard alarm after hitting what they suspected was a whale off the coast of Newfoundland in May; two crew members were injured in the collision. At the beginning of the 2013 America’s Cup on San Francisco Bay, a whale was reported in the bay and organizers were prepared to delay a race if it wandered onto the course. In 2022, the start of SailGP’s $1 million, winner-take-all Season 2 championship race on the same area of San Francisco Bay was delayed when a whale was spotted on the course.

In 2005, the first South African yacht to challenge for the America’s Cup hit a whale with its 12-foot keel during training near Cape Town, stopping the 75-foot sloop dead in the water, injuring two crewmembers and snapping off both steering wheels.

Orcas have sunk another vessel off the European coast. Why won't they stop ramming boats?

The orcas are at it again: for the seventh time in four years, a pod of whales has sunk a boat after ramming it in Moroccan waters off the Strait of Gibraltar. 

The 15 metre-long yacht Alborán Cognac, which carried two people, encountered the highly social apex predators at 9am local time on Sunday, Spain's maritime rescue service said.

The passengers reported feeling sudden blows to the hull and rudder before water started to seep into the sailboat. It is not known how many orcas were involved.

After alerting rescue services, a nearby oil tanker took them onboard and carried them to Gibraltar, a British overseas territory on Spain's southern coast.

Nothing could be done to save the sailboat, which drifted and eventually sank. 

It's the latest incident in what has become a trend of hundreds of interactions between orcas and boats since the "disruptive behaviour" was first reported in the region in May 2020. 

The origin of this new behaviour has baffled scientists, though the leading theory suggests this "social fad" began as a playful manifestation of the whales' curiosity.

Where have orcas interacted with boats?

The latest data from the Atlantic Orca Working Group (GTOA), an organisation that contributes to the animals' conservation and management, shows that there have been at least 673 interactions since 2020. 

GTOA defines interactions as instances when orcas react to the presence of approaching boats with or without physical contact. 

The map below shows the highest numbers of encounters from April to May 2024 took place off Spain's southern coast in the Strait of Gibraltar (red zones), with some lesser activity in surrounding areas (yellow zones). 

A 2022 peer-reviewed study published in the Marine Mammal Science journal found the orcas in these areas preferred interacting with sailboats — both monohulls (72 per cent) and catamarans (14 per cent) — with an average length of 12 metres.

A clear pattern emerged of orcas striking their rudders, while sometimes also scraping the hulls with their teeth. Such attacks often snapped the rudder, leaving the boat unable to navigate.

"The animals bumped, pushed and turned the boats," the authors of the report said. 

Adding this week's encounter, there have been seven reported cases of orcas damaging a boat so badly that it has sunk, though the people onboard were rescued safely each time.

In June 2023, a run-in with the giant mammals in the Strait of Gibraltar forced the crew competing in The Ocean Race to drop its sails and raise a clatter in an attempt to scare the approaching orcas off. 

No-one was injured, but Team JAJO skipper Jelmer van Beek said that it had been a "scary moment".

"Three orcas came straight at us and started hitting the rudders," he said.

"Impressive to see the orcas, beautiful animals, but also a dangerous moment for us as a team ... Luckily, after a few attacks, they went away."

After analysing 179 videos and photos of these types of interactions, which lasted on average 40 minutes, researchers concluded there was no reason to classify the events as intentionally hostile behaviour.

"The behaviour of orcas when interacting with boats is not identified as aggressive," they said.

"One of their main motivations has been identified as competition with boats for speed."

Still, the researchers of the study admitted they were not sure what triggered the novel behaviour in 2020.

"We are not yet certain what the origin of these interactions is, but it is still suspected that it could be a curious and playful behaviour," they wrote.

"[The behaviour] could be self-induced, or on the other hand it could be a behaviour induced by an aversive incident and therefore a precautionary behaviour."

Are the same orcas responsible for these incidents?

Out of around 49 orcas living in the Strait of Gibraltar, GTOA researchers found a total of 15 whales  from at least three different communities participated in the unusual interactions with boats between 2020 and 2022.

Most of those that engaged with greater intensity were juveniles, though it's unclear if others have since joined the group.

These giant mammals, which belong to the dolphin family, can measure up to eight metres and weigh up to six tonnes as adults.

The director of the Orca Behaviour Institute, Monika Wieland Shields, has said there is no evidence to prove the theory these whales were seeking vengeance against humans for a past trauma.

"While I'm sure it feels like an attack for the people on board, for the whales themselves, it really looks more like play behaviour," she said.

"There's something intriguing or entertaining to them about this [boat rudder] mechanism and they're just showing a lot of curiosity about it."

Ms Wieland said it's likely this new behaviour spread through the population as a kind of "social fad".

"Orcas are highly intelligent, very social animals, and with that comes a tendency to be curious about and explore your environment," she said.

"One thing that we see are these kind of fad behaviours that will appear in a certain population.

"One whale discovers something, they find it entertaining or interesting, or fun — it's some type of game. And then they will teach that to other members of their family group."

Are orcas dangerous to humans?

While orcas have earned their fearsome reputation for preying on other marine animals, there is no record of them killing humans in the wild. 

In captivity, orcas have killed four people since the 1990s, though it's unclear whether the deaths were accidental or deliberate attempts to cause harm.  

Ms Shields said she was worried the recent interactions between orcas and boats would skew people's perceptions of these mammals.

"I am concerned that people are going to react with fear, potentially injure or shoot at some of these whales," Ms Shields said.

"We really need to educate boaters about the best things that they can do to make themselves less attractive to the whales and the best case scenario would be the whales lose interest in this and move onto something less destructive."

Spain's Transport Ministry advises that whenever boats observe any changes in the behaviour of orcas — such as in their direction or speed — they should leave the area as soon as possible and avoid further disturbance to the animals.

The ministry also states every interaction between a ship and an orca must be reported to authorities.

Orcas rip rudder off boat and follow it all the way to port, in 1st known attack of its kind

Previous reported interactions between orcas and sailboats followed a clear pattern, with the animals losing interest and swimming away once they had broken the rudder.

A group of orcas recently nearly sank another sailboat in the Strait of Gibraltar and followed the vessel all the way to port — marking the first-known case of the killer whales stalking a boat after destroying its rudder.

Orcas started behaving unusually and attacking boats in 2020. Since July 2020, there have been 744 reported encounters, 505 of which involved contact between the animals and the ship, according to the Atlantic Orca Working Group (GTOA). One in five interactions have prevented boats from sailing on and three have ended in vessels sinking.

Most of these interactions ended in the orcas losing interest in the boat once they'd broken its rudder. But during the recent attack on the night of May 24, the orca pod continued to stalk the yacht "Mustique" even after damaging the vessel. It is unclear whether this marks a shift in the orcas' learned pattern of aggressive behaviors towards sailboats .

"They didn't leave after the rudder was removed," April Boyes, an experienced sailor who was aboard the Mustique, told Live Science in a message on social media. 

The crew first spotted the orcas around 9:30 p.m. local time as they were sailing through the Strait of Gibraltar. "It didn't take long for them to start hitting our rudder and the force of this would spin the helm violently and you could feel the vibration through the deck," Boyes wrote in a blog post .

After breaking the rudder , the orcas seemed to lose interest and swam away. But 20 minutes later, the pod returned and began circling the boat. "After an hour of the orcas continuing to hit the rudder it was evidently now completely destroyed and water started to flow into the boat," Boyes wrote.

The crew alerted the Spanish coastguard, which towed the boat to the port of Barbate. But even then the orcas lingered. "The orcas continued to follow the boat until we got inshore," Boyes wrote.

Experts with the GTOA, who have been keeping track of the unusual encounters between orcas and boats off the Iberian coast, declined to comment on whether the new behavior of pursuing the battered boat signified a shift in the orcas' strategy.

"Navigators are not sending us reports of the interactions so we cannot answer blindly and without information about these cases," Alfredo López Fernandez , a biologist at the University of Aveiro in Portugal and representative of the GTOA, told Live Science in an email.

Spanish officials and researchers from the group Conservation, Information and Research on Cetaceans (CIRCE) plan to use satellite trackers to monitor six orcas that have been involved in attacks. One orca has already been tagged, government representatives said in a statement .

"Thanks to the GPS of the killer whales and prediction models, we have some variables that allow us to predict where these animals are going to be," Renaud de Stephanis , the president of CIRCE, told the Spanish broadcaster RTVE . "100% of the attacks that have occurred since March until now could have been prevented simply by people being informed."

But some experts think the measure could backfire. "Many of us have reservations because we think that satellite tagging is not going to be of any use in relation to interactions, if not to aggravate the situation, because it is done by shooting and the killer whales will surely not find it very funny," López Fernandez told RTVE. 

De Stephanis also recently suggested that sailors could deter orcas by gluing anti-pigeon spikes onto the rudder. "We believe that one solution to reduce the impact, which is cost-effective and highly effective, would be to install anti-pigeon spikes cut to 3 cm [1.2 inches] on the back of the rudder," he wrote in a Facebook post on June 2. "The system should be easy to install (using Velcro or underwater glue) and easy to remove."

For now, sailors should "be prepared if they sail in those areas, avoid sailing at night and approaching the coast, as far as possible," López Fernandez told Live Science.

Why Has a Group of Orcas Suddenly Started Attacking Boats?

Killer whales in a group near Spain and Portugal may be teaching one another to mess with small boats. They sank their third vessel earlier this month

By Stephanie Pappas

A group of three orcas, also known as killer whales, are seen swimming in the Strait of Gibraltar. Individuals in the critically endangered subpopulation have been attacking boats off the coast of the Iberian Peninsula.

A trio of orcas attacked a boat in the Strait of Gibraltar earlier this month, damaging it so badly that it sank soon afterward.

The May 4 incident was the third time killer whales ( Orcinus orca ) have sunk a vessel off the coasts of Portugal and Spain in the past three years. The subpopulation of orcas in this region began harassing boats, most often by biting at their rudder, in 2020. Almost 20 percent of these attacks caused enough damage to disable the vessels, says Alfredo López, an orca researcher at the Atlantic Orca Working Group (GTOA), which monitors the Iberian killer whale population. “It is a rare behavior that has only been detected in this part of the world,” he says.

Researchers aren’t sure why the orcas are going after the watercraft. There are two hypotheses, according to López. One is that the killer whales have invented a new fad, something that subpopulations of these members of the dolphin family are known to do. Much as in humans, orca fads are often spearheaded by juveniles, López says. Alternatively, the attacks may be a response to a bad past experience involving a boat.

The first known incident occurred in May 2020 in the Strait of Gibraltar, an area with heavy boat traffic. Since then GTOA has recorded 505 cases of orcas reacting to boats. Sometimes they simply approached the vessels, and only a fraction of cases involved physical contact, López says. In a study published in June 2022 in Marine Mammal Science , he and his colleagues cataloged 49 instances of orca-boat contact in 2020 alone. The vast majority of the attacks were on sailboats or catamarans, with a handful involving fishing boats and motorboats. The average length of the vessels was 12 meters (39 feet). For comparison, a full-grown orca can be 9.2 meters (30 feet) long.

The researchers found that the orcas preferentially attack the boats’ rudder, sometimes scraping the hull with their teeth. Such attacks often snap the rudder, leaving the boat unable to navigate. In three cases, the animals damaged a boat so badly that it sank: In July 2022 they sank a sailboat with five people onboard. In November 2022 they caused a sailboat carrying four to go down. And finally, in this month’s attack, the Swiss sailing yacht Champagne had to be abandoned, and the vessel sank while it was towed to shore. In all cases, the people onboard were rescued safely.

In 2020 researchers observed nine different individual killer whales attacking boats; it’s unclear if others have since joined in. The attacks tended to come from two separate groups: a trio of juveniles occasionally joined by a fourth and a mixed-aged group consisting of an adult female named White Gladis, two of her young offspring and two of her sisters. Because White Gladis was the only adult involved in the initial incidents, the researchers speculate that she may have become entangled in a fishing line at some point, giving her a bad association with boats. Other adult orcas in the region have injuries consistent with boat collisions or entanglement, López says. “All this has to make us reflect on the fact that human activities, even in an indirect way, are at the origin of this behavior,” he says.

The safe rescue of everyone involved, however, suggests to Deborah Giles that these orcas don’t have malevolent motivations against humans. Giles, science and research director of the Washington State–based nonprofit conservation organization Wild Orca, points out that humans relentlessly harassed killer whales off the coasts of Washington and Oregon in the 1960s and 1970s, capturing young orcas and taking them away for display at marine parks. “These are animals that, every single one of them, had been captured at one point or another—most whales multiple times. And these are whales that saw their babies being taken away from them and put on trucks and driven away, never to be seen again,” Giles says. “And yet these whales never attacked boats, never attacked humans.”

Though it’s possible that the orcas around the Iberian Peninsula could be reacting to a bad experience with a boat, Giles says, it’s pure speculation to attribute that motivation to the animals. The behavior does seem to be learned, she says, but could simply be a fad without much rhyme or reason—to the human mind, anyway. Famously, some members of the Southern Resident orcas that cruise Washington’s Puget Sound each summer and fall spent the summer of 1987 wearing dead salmon on their head. There was no apparent reason for salmon hats to come in vogue in orca circles, but the behavior spread and persisted for a few months before disappearing again. “We’re not going to know what’s happening with this population,” Giles says, referring to the Iberian orcas.

The Iberian orca attacks typically last less than 30 minutes, but they can sometimes go on for up to two hours, according to the 2022 study. In the case of the Champagne, two juvenile killer whales went after the rudder while an adult repeatedly rammed the boat, crew members told the German magazine Yacht . The attack lasted 90 minutes.

The Iberian orca subpopulation is considered critically endangered, with only 39 animals the last time a full census was conducted in 2011. A 2014 study found that this subpopulation follows the migration of their key prey , Atlantic bluefin tuna—a route that puts them in close contact with human fishing, military activities and recreational boating. Maritime authorities recommend that boaters in the area slow down and try to stay away from orcas, López says, but there is no guaranteed way to avoid the animals. He and his colleagues fear the boat attacks will come back and bite the orcas, either because boaters will lash out or because the attacks are dangerous to the animals themselves. “They run a great risk of getting hurt,” López says.

Terrifying footage has emerged of the moment a pod of orcas descended on a British couple’s yacht – and proceeded to spend the next hour ramming the vessel.

Janet Morris and Stephen Bidwell, of Cambridge, were enjoying the second day of a week-long sailing course on the Strait of Gibraltar when they felt a banging on the hull.

“I couldn’t believe it when I saw them – it’s extremely rare. We were sitting ducks,” Janet, a business consultant, told the Daily Mail of the surreal moment.

Video of the incident shows the aggressive pod repeatedly swimming into the hull and rudder of the 46-foot Bavaria yacht.

The crew struggled to keep the whales at bay while also battling blustery winds and high swells.

“We were amazingly calm but underneath we were thinking, ‘Oh my god,’” Janet explained.

“Because everyone was calm it felt okay, but we were petrified, it wasn’t until afterwards that we talked about being very scared. We got our valuables and our passports and talked about getting the life raft ready.”

“We all remained calm because we were aware that if any of us got anxious it would be infectious. We were able to do that because the skipper was so calm,” Stephen, a photographer, added.

“Orcas enjoy the thrill of the chase, so ideally we’d have kept still, but that wasn’t possible because of the winds.”

The orcas ultimately gave up the chase after about an hour, but the crew decided to return to shore because the boat’s steering was failing.

On their return to port, they realized that the whales had taken chunks of the rudder.

Both Janet and Stephen are qualified to captain and charter sailboats.

They were taking the course off the coast of Tangier to rack up more sailing hours.

The couple was asleep below deck in preparation for their night watch shift when the whales first descended.

“We were on the course to get experience, and we’ll know what to do if this happens again,” Janet said.

The Strait of Gibraltar is known for its orca population, which can cause problems for boaters.

In March, a sailboat was disabled off Cape Spartel when a pod of orcas broke the rudder, The Maritime Executive reported .

Between July and October 2020, there were at least 40 orca incidents involving sailboats in the area around Spain and Portugal, the outlet said.

Why orcas keep sinking boats

Scientists have some theories why killer whales have seriously damaged boats about a dozen times this year off the coast of Spain and Portugal

In the early morning Thursday, killer whales smashed into a sailboat off the southern coast of Spain, puncturing its hull and damaging its rudder. Spanish authorities raced to save the sinking vessel, according to Reuters , but it was in such disrepair it had to be towed ashore.

It wasn’t the first attack by an orca, or killer whale, off the coast of Spain and Portugal this year. And it may not be the last time one chews a rudder or crashes into a hull. Normally, killer whales aren’t considered dangerous to humans. But pods of killer whales have done serious damage to boats in the region about a dozen times already this year, according to the Grupo de Trabajo Orca Atlántica, or GTOA, a research group studying the region’s killer whales, part of a rise in attacks first observed in 2020.

Stories and videos of the attacks widely shared on social media have turned the orca into a meme. After the marine mammals struck some fancy yachts, some observers are calling the strikes concentrated around the Strait of Gibraltar, where the whales congregate in the spring and summer, an act of anti-capitalist solidarity from “orca comrades” and “orca saboteurs.” For others, the series of strikes is eerily similar to a scene in James Cameron’s latest “Avatar” movie , “The Way of the Water.”

So what is happening? The scientists studying the whales themselves aren’t entirely sure, either. But they have two leading ideas:

Theory No. 1: The orcas are playing around

Closely related to bottlenose dolphins, orcas are highly intelligent and curious marine mammals. Using a series of underwater pulses and whistles, the whales communicate with such sophistication that pods form their own dialects and parents teach their young hunting methods that are passed along for generations.

After learning a new behavior, juvenile orcas often keep repeating it ad nauseam. (In that way, they are a lot like human youngsters.) Playing around is just a part of learning how to be an apex predator.

That matches the pattern of attacks whale scientists have witnessed this year, according to Alfredo López Fernandez, a researcher at the University of Aveiro in Portugal working with GTOA.

In this case, the behavior is “self-induced,” López Fernandez said, and not caused directly by some outside (i.e., human) provocation. “Which means that they invent something new and repeat it,” he added.

But there’s another potential motivation that sounds straight out of “Moby Dick.”

Theory No. 2: The orcas want vengeance

Orcas off the Iberian Coast like to follow fishing vessels to snag bluefin tuna before fishermen can reel them in, putting the aquatic mammals at risk of being struck or entangled. Scientists have seen killer whales in those waters with fishing lines hanging from their bodies.

So it is possible, López Fernandez said, an orca had a bad run-in with a boat in the past, and is now teaching other killer whales how to attack vessels as well. The team suspects a female adult named White Gladis may be the one doing so.

López Fernandez emphasized we don’t have enough information to know the real reason behind the attacks yet. Even assuming the second theory is true, “we don’t know what that triggering stimulus could have been,” he said.

With only 39 orcas counted in 2011, the Iberian orca subpopulation is considered critically endangered by the International Union for Conservation of Nature. The impact that entanglements and boat strikes are having on all sorts of whales and dolphins around the world underscores that humans are a bigger threat to them than they are to us.

“All this has to make us reflect on the fact that human activities, even in an indirect way, are at the origin of this behavior,” López Fernandez said.

Boats that follow orca-encounter protocol may escape unscathed — but if an orca's in a particular mood, all bets are off

• Orcas have been interacting with boats in the Atlantic since 2020, drawing international attention.
• Scientists have developed guidelines for boaters who come into contact with killer whales.
• But data shows that if a killer whale really wants to interact with a boat, humans can't do much.

Orcas are having a whale of a time recently, ramming and damaging boats around the Spanish and Portuguese coasts over 200 times since summer 2020.

Advocacy groups have released recommendations for how to act if you come into contact with killer whales while boating . Some of the recommendations include slowing down, turning off the engine, and staying quiet to avoid exciting the orcas.

But following these protocols may not be enough, said Mónica González of the Coordinadora para o Estudo dos Mamíferos Mariño, an organization in Spain known as CEMMA that studies marine animals.

González and her colleagues have been tracking these interactions since 2020. Recently, in a webinar hosted by The Orca Behavior Institute, González said that they noticed sometimes orcas damaged a boat regardless of whether the people on board followed proper protocol or not.

González analyzed accounts from 231 boats that reported physical contact with an orca in the Strait of Gibraltar since 2020. Her team found that 63% of slightly damaged boats didn't follow protocol, compared with 36% that did.

But in looking at cases of severe damage , when the boat stopped working, she said they found something different. Roughly half of the damaged boats followed protocol, and the other half didn't. The protocol didn't seem to have an effect.

"In very severe damage, when towing is required, we don't find significant evidence to follow or not follow our protocol," she said in the webinar. "So our protocol runs, but not when we're talking about serious damage."

The orcas, it seems, will continue damaging the boat if they're in the mood to do so , and there's not much boaters can do at that point.

No one is sure why orcas have been ramming boats in the first place. But the leading ideas are curious young orcas or defensive behavior by orcas that have been harmed before , González said in the webinar.

In either case, our own actions may not deter an orca already set on its course.

" Orcas love having fun, but they can have a much darker side to their mischief when they don't like what's been happening to them," John Hargrove, a former SeaWorld employee-turned-orca-activist, told Bloomberg in May.

4th July 2024: Today the LEGO Group unveils the LEGO® Ideas JAWS set, a brick-built diorama commemorating the infamous 1975 blockbuster movie “ JAWS ,” from Universal Pictures and Amblin Entertainment. To celebrate the launch, the LEGO Group, in partnership with Universal Products & Experiences, has created the first ever summer “brick-buster” mini-film, “ JAWS …in a Jiffy,” a playful recreation of this iconic summer blockbuster movie – told in just 90-secs. The film features all the favourite scenes, plus a surprise minifigure reveal at the end, featuring award-winning director Steven Spielberg behind the clapperboard. Fans can watch the film here .

The LEGO Ideas JAWS set is a meticulously designed recreation of one of the most famous scenes from the movie, allowing fans to relive the suspense and excitement of Spielberg's masterpiece in brick form. Originally conceived by LEGO fan Johnny Campbell, via the LEGO Ideas community platform, the 1497-piece set captures key elements and characters from the film in LEGO minifigure form – including Police Chief Martin Brody, marine biologist Matt Hooper and sailor Sam Quint. The set also features the iconic Orca boat, with a detailed cabin with a removable roof, an adjustable boom and rigging, plus lots of recognisable accessories, such as a revolver, compass, fishing rod, harpoon, spear, and the yellow barrels that were pivotal to the movie plot.

The set can either be placed on a brick-built seawater base with the JAWS LEGO shark model attacking the Orca boat. Also attached is a printed tile with Chief Brody’s famous line ( “You’re gonna need a bigger boat” ) to the base to complete this nostalgic and playful centerpiece. Alternatively, the Shark can be displayed separately from the boat, on its own stand.

Speaking about how he approached the design for the set, fan designer Johnny Campbell, reveals: " JAWS is my favourite movie of all-time, so I really wanted to recreate it in LEGO bricks. LEGO building has always been a part of my life in some shape or form but in order to get all of the finer details, I actually freeze-framed JAWS as I watched it so that I could catch a glimpse of the finer details taking notes as I went along. It is just mind-blowing that my design is now an official LEGO set. I can't wait to stand in a LEGO shop looking at the shelves and seeing a set that I have been involved with and watching someone buying it. It’s every LEGO fan’s dream!”
