In recent news, a small group of wild orcas off the Iberian Peninsula’s western coast has caused three boats to sink since last summer and disrupted the trips of dozens of others. The orcas have been ramming into sailboats in high-trafficked seas near Morocco, Portugal, and Spain, causing physical damage about 20% of the time. This unusual behavior has left researchers puzzled, and they do not know what is driving these orcas towards the boats.

The Encounter: An Unnerving Experience for Sailors

The orcas, the largest of the dolphin family, have been known to touch and bump boats, but ramming them is unusual. The skipper of a 46-foot sailing cruiser reported that a small group of orcas kept pace with the boat, slamming into its side and chewing at the rudder. The crew signaled their predicament to the Spanish Coast Guard, but there was nothing they could do for about an hour. The incident left sailors worried about safety and ship damage.

Scientists Attempt to Understand the Behavior

Wild orcas are not generally considered dangerous to humans, and the animals show no signs of wanting to hurt humans. Researchers have been tracking direct interactions with orcas since 2020 and have documented the orcas approaching or reacting to vessels about 500 times. The orcas off the Iberian coast are considered an endangered population, but scientists do not know how to stop the small group’s recent behavior, which has caught the attention of the Spanish and the Portuguese authorities.

Possible Theories Behind the Behavior

Scientists have speculated that the orcas’ behavior may have started after an incident between an animal and a boat, such as an entanglement in fishing line, or an invented behavior from young orcas that is being repeated. However, those remain only theories, and it is unclear why the orcas are ramming into sailboats. Some scientists have suggested that the behavior may be play, and the orcas are getting a reward or thrill from it.

Impact on Orcas and Conservation Efforts

Conservationists are worried about how humans will treat the orca population, especially as sailors in the region express growing frustration with the animals. The behavior is putting pressure on an already vulnerable species. Researchers say that aside from having sailors avoid the area, they do not know how to stop orcas from bothering sailboats, which tend to be quieter than most vessels and therefore more attractive to the animals.


The puzzling pattern of behavior displayed by a small group of orcas in Southern Europe has left researchers puzzled, and the reasons for the behavior remain unclear. The behavior has raised concerns about the safety of sailors and the impact on the vulnerable orca population. While scientists have put forward several theories, they do not know how to stop the behavior. The incident serves as a reminder of the unpredictable nature of wildlife and the need for caution when interacting with them. It is crucial to continue studying these animals to understand their behavior and ensure their protection. Sailors should remain vigilant while navigating these waters to avoid any potential harm caused by the orcas.
