Orcas' Boat Attacks Driven by Learned Behavior and Strategy Development.
Killer whales, also known as orcas, are increasingly attacking yachts along Europe's Iberian coast, with some suggesting that their tactics are becoming more stealthy. While some researchers believe that these incidents are not meant as attacks, but merely represent playful behavior, others think that the orcas are carrying out revenge attacks due to past trauma. However, not all experts agree with this hypothesis, and it's important to remember that this behavior is not being transmitted to pods in other parts of the world.
