Orcas, also called killer whales, are very intelligent animals. They live in family groups and work together to catch food.
Orcas, also known as killer whales, are some of the most intelligent animals in the ocean. They live in family groups, communicate with each other, and work together to catch food. However, in recent years, scientists have noticed a strange new behaviour: some groups of orcas have been damaging boats.
Since 2020, hundreds of encounters have been reported, mainly near the coasts of Spain and Portugal. In many cases, orcas have swum towards sailing boats and repeatedly hit or bitten the rudder. This can make it difficult for the boat to turn, and a few boats have even sunk after being badly damaged. Luckily, there have been no confirmed cases of orcas deliberately attacking people.
Scientists believe the behaviour is deliberate because the orcas often target the rudder instead of hitting different parts of the boat. Young orcas have also been seen copying older ones, suggesting that they may be learning this behaviour from each other.
No one knows exactly why this is happening. Some researchers think one or more orcas may have had a bad experience with a boat and then started reacting to similar vessels. Others believe the animals may simply be curious or playing with something new in their environment.
This has created a dilemma for sailors and scientists. People want to protect these intelligent animals, but they also need to keep boats and their passengers safe. Experts now advise sailors to stay calm, reduce their speed, and report any encounters.
The behaviour is especially intriguing because orcas are known to learn from one another. This means that one new behaviour could spread through different groups over time.
At the moment, every explanation is still speculative because scientists do not have enough evidence to be certain. Research is continuing, and experts hope they will soon understand why the orcas are behaving in this unusual way.
These encounters are a reminder that the oceans still contain many mysteries. Even after many years of studying marine life, there is still much to learn about these remarkable animals.
