Speaker 1 (00:06):
I'm Darren Marler, and this is a weird darkness bonus bite.
Something's happening in the waters between Spain and Portugal that
marine biologists can't fully explain. A small group of orcas,
maybe forty individuals at most, has developed a disturbing fixation
with sailing boats. They're not hunting for food, they're not
defending territory. They are systematically destroying rudders with a precision

(00:30):
that feels almost methodical. The encounters follow a specific routine
that sailors have come to dread. First comes the steady,
deep breathing, that distinctive woosh of orca exhalations breaking the
surface tension. Then the clicks and whistles of their communication,
a language humans still can't decode. The bolt jolts violently

(00:52):
as several tons of marine predators slam into the hull.
The orcus circle back ram again, always targeting the same spot,
the rudder beneath the stern. On August thirtieth, twenty twenty five,
Valentin Otero was sealing his traditional wooden ship off O
Grove when he heard two solid impacts against his vessel.

(01:12):
When he looked over the side, he saw them A
massive orca around twenty three feet long, accompanied by a
smaller companion. The crew described being completely terrified as they
realized the killer whales were actively hitting their boat. The
rudder was destroyed within minutes. That same day, Spanish Maritime
Rescue had barely finished towing Otero's damaged vessel back to

(01:35):
harbor when another distress call came in. A second boat,
this one near as within the Pontifadra Estuary, had sprung
a leak after its own orca encounter. The rescue crews
suspected it was the same pod. The Iberian orcas, a
critically endangered subpopulation with fewer than forty individuals, have been
doing this since May of twenty twenty. That's when sailors

(01:58):
first reported these bizarre targeted attacks in the Straitageibraltar and
area some now call Orca Alley. Since then, researchers have
documented hundreds of similar incidents, spreading along the coasts of Spain, Portugal,
and even reaching as far north as France's Bay of Biscay.
The precision of these encounters disturbs even experienced marine biologists.

(02:20):
The orcas don't randomly bash into boats. They swim directly
at the stern using their massive heads as battering rams
against the rudder mechanism. Once they've broken or torn off
the rudder, effectively crippling the vessel's ability to steer, they
simply leave. Several boats have sunk completely, many more have
been left disabled, their crews helpless as tons of intelligent

(02:44):
predators circle their increasingly fragile vessels. The sound alone terrifies
the sailors, the crunch of fiberglass giving way, the groan
of compromised hull integrity, all accompanied by those steady ORCA
breaths and their constant clicking communication. In July twenty twenty five,
two French sailors issued a may day call from waters

(03:05):
near Dubba in northern Spain. Rescuers described the incident as
uncommon for that region, though the behavior matched exactly what's
been happening further south. The sixty year old sailor and
his companion were safely evacuated, but their yacht was destroyed.
The boats being targeted share specific characteristics. They're not super

(03:25):
yachts or commercial fishing vessels. The Orcas focus almost exclusively
on sailing boats, the kind of modest craft that regular
people save up Dubai vessels worth about as much as
a used car. Something about these particular boats triggers this behavior.
The killer whale brain ranks among the most complex on

(03:45):
the planet. Their cerebral cortex shows more intricate folding than
even human brains, giving them extraordinary capacity for memory, learning
and with scientists reluctantly call emotion. These aren't simple predators
operating on instinct. They are intelligent beings with culture passed
down through generations like family traditions. Lori Marino, a neuroscientist

(04:08):
who studies whale cognition, points out that orcas experience empathy
and more in their dead. They're certainly intelligent enough to
understand concepts like revenge or retribution, which makes their behavior
toward boats even more unsettling, because if they wanted to
kill humans, they easily could. The orcas never attack people directly.

(04:30):
They don't try to capsize boats by hitting the hull
where it would cause catastrophic damage. They obsess over one
specific component, the rudder. It's almost like they've identified the
one piece of equipment that will disable a boat without
necessarily sinking it. Marine biologist Ronald di stefanis who the
Spanish government asked to study the problem, spent months observing

(04:52):
these encounters. The orcas approach with what witnesses describe as
an eerie calmness. No aggressive splashing, no hostile, vile vocalizations,
just that steady, methodical ramming until the rudder breaks. Scientists
have proposed multiple explanations, each more unsettling than the last.
The leading theory suggests this started with a single orca

(05:15):
and adult female researchers call White Gladys. Something happened to her,
possibly a traumatic collision with a boat that left her
injured or killed a calf, but instead of avoiding boats afterward,
she began targeting them. Younger orcas watched and learned. The
behavior spread through the pod like a cultural phenomenon, each
generation teaching the next this specific hunting pattern for boats,

(05:39):
except they're not hunting in the traditional sense. They don't
eat what they destroy. Some researchers compare it to play behavior,
like a powerful dog playing too rough with a small child.
The orca doesn't understand its own strength or the fear
that it causes, but this comparison falls apart when faced
with the systematic nature of the attack. These animals know

(06:01):
exactly what they are doing to the rudders. Hal Whitehead,
who studies whale culture, suggests something even stranger. He thinks
the boat ramming might be how this particular pod strengthens
its group identity, like a shared ritual or tradition that
binds them together as a community. The attacks aren't about territory.
Ocean animals don't really claim territory the way land animals do.

(06:25):
They're about something else entirely. What started in deep waters
has spread to coastal areas. The August twenty twenty five
incidents occurred in shallow estuaries where the pod doesn't usually hunt.
Researchers with the Bottlenose Dolphin Research Institute spotted the orcas
preying on octopus in these coastal waters, a deviation from

(06:45):
their usual diet of bluefin tuna. The change in hunting
grounds coincides with recovered tuna populations in the Atlantic. The
orcs don't need to spend as much time hunting for food,
leaving them with something marine biologists hesitate to call boredom.
These might be teenagers with too much free time looking
for stimulation, but calling it play feels wrong. When sailors

(07:08):
describe their terror One crew member from the August thirtieth
attacks said they completely freaked out when they realized the
killer whales were hitting their boat. The Spanish newspaper accounts
described grown adults paralyzed with fear as these massive predators
methodically destroyed their only means of steering. Desperate sailors have
tried everything to stop the attacks. Some blast death metal

(07:32):
music through underwater speakers. Others bang steel poles against their hulls,
creating a cacophony they hope will drive the orcus away.
The illegal firecrackers have been thrown at the animals. One
group tried painting their hull a different color, thinking visual
changes might help. Nothing works consistently. Sometimes the orcas seem
to lose interest in swim away, other times they appear

(07:55):
to enjoy the noise, ramming boats even harder. The International
Whaling Commission warned and that aggressive responses might actually reinforce
the behavior, making attacks more severe. Spanish authorities considered adding
spikes or rough surfaces to rudders, hoping to make them
less appealing targets, but the orcas adapt quickly. They've already

(08:16):
learned to distinguish between different types of boats. Focusing their
attention on sailing vessels while largely ignoring motor boats in
the same waters. The only semi reliable advice for sailors
comes down to this, Remain calm, stay silent, and try
to motor away slowly, turn off engines if the orcis
get close, lower the sails, deactivate sonar and autopilot systems,

(08:41):
essentially play dead and hope they lose interest. Each Iberian
orca can be identified by unique barkings, and researchers have
watched specific individuals participate in multiple attacks. They are not
random encounters with different whales. The same orcas return again
and again, perfecting their technique. Video footage from the Pontevedra

(09:04):
Civil Guard shows orcas continuing to ram a sailboat even
while it was being towed to safety. They understood the
boat was damaged, possibly that it was being rescued, and
kept attacking anyway. This wasn't about disabling a threat or
hunting prey. This was something else. The communication between attacking
orcas suggests coordination. Those clicks and whistles aren't random noise.

(09:29):
They're a language, possibly discussing strategy. Marine microphones have recorded
with sounds like teaching behavior, with older orcas apparently instructing
younger ones on proper ramming technique. Some scientists believe the
orcas might be passing on specific information about boat weaknesses.
They've learned that fiberglass hulls respond differently than wooden ones.

(09:51):
They know exactly where they hit from maximum rudder damage.
This knowledge spreads through the pod. Like technical expertise. ORCA
populations worldwide display unique cultural behaviors. Some groups have learned
to create waves that wash steals off ice floes, Others
stun fish with tail slaps. The Iberian pods boat ramming

(10:14):
joins a long list of learned behaviors that define specific
ORCA communities. In the Pacific, orcas once developed a trend
of wearing dead salmon on their heads like hats. The
behavior appeared suddenly in nineteen eighty seven, spread through the pod,
then disappeared just as mysteriously. Scientists called it a fad,

(10:35):
a cultural movement that served no survival purpose but seemed
a matter to the whales involved. The boat attacks have
lasted much longer than that salmon hat phase, five years
in counting, with no sign of stopping. Young orcas are
growing up with this behavior as part of their normal world.
To them, ramming boat rudders might be as natural as

(10:56):
hunting tuna. Alex Zerbini from the University of Washington's Cooperative
Institute for Climate, Ocean and Ecosystem Studies participated in workshops
trying to understand the phenomenon. His report to the International
Whaling Commission used careful scientific language, but the implications were clear.
These Orcas have developed a cultural tradition that directly involves

(11:17):
attacking human vessels, and nobody knows how to make them stop.
The recent move into coast to leestuaries as another layer
of concern. These shallow water attacks break the previous pattern
of deep water encounters. The Orcas are expanding their operational territory,
bringing their boat ramming behavior into areas where smaller vessels

(11:37):
seek shelter. On August twenty first, twenty twenty five, German
sailors watched their rudder get torn off in the Vego Estuary.
The Orcas played with their sailboat like a toy, ramming
it repeatedly, even as rescue vessels arrived. The Pontevedra Civil
Guards video shows the orcas surface again and again. Their
distinctive black and white patterns visible as they circle the

(11:59):
daydamaged vessel. The shallow water attacks trap sailors in a
different way. In deep water, a damaged boat might drift
safely for hours while waiting for rescue. In coastal areas,
rocks and shorelines pose immediate threats to vessels that can't steer.
The orcas seem to understand this vulnerability. An app now

(12:21):
tracks orca sidings in real time, allowing boats to plot
courses that avoid known pod locations. Sailors share information through
informal networks, warning each other about recent encounters. Some have
started sailing and convoys, hoping group presence might deter attacks,
but the tracking only works when the orcas surface where expected.

(12:43):
They've been spotted, hundreds of biles from their last known position,
appearing suddenly, and waters previously considered safe. Their hunting grounds
span from Morocco to France, an area too vast to
monitor completely. Maritime authorities have developed respond protocols that feel
more like natural disaster preparation than wildlife management. Rescue vessels

(13:06):
stay on alert, emergency equipment gets tested more frequently. Insurance
companies have started asking specific questions about Orca and counter preparations.
Recent incidents show the behavior spreading beyond the original pod.
Marine biologists worry that orcas from other populations might learn
the technique through observation. Killer whales are known to share

(13:28):
information across family groups during social gatherings. The possibility of
this behavior spreading to other orca populations keeps researchers awake
at night. The Iberian orcas number fewer than forty individuals,
but if atlantic Orca populations adopt similar behaviors, the implications
for maritime travel could be severe. Already, some sailors refuse

(13:51):
to transit the area. Yacht delivery services charge premium rates
for passengers through orca. Alley racing committees have re routed
competitions to avoid known encounter zones. The orcas have effectively
claimed control over significant portions of European coastal waters. Sailors
who have experienced attacks describe a specific type of fear.

(14:14):
It's not like a storm, where wind and waves follow
predictable patterns. It's the intelligence behind the attacks that unsettles them.
The orcas watch them make decisions, communicate with each other
about strategy. One rescued crew member described making eye contact
with an attacking orca. The whale's eye tracked his movements
as he tried to secure loose equipment. It knew he

(14:37):
was there, understood he was afraid, and continued ramming the
rudder anyway. That deliberate awareness haunts sailors more than the
physical damage. The sound stays with them too. Veterans of
multiple encounters say they recognize individual orcas by their breathing patterns.
They know which whales prefer to attack from the port side,

(14:58):
which one's surface more frequently. To observe their work, These
aren't anonymous predators. They are repeat offenders with distinctive methods.
