Scientists have a new theory about why orcas are ramming yachts in the Iberian Peninsula: it’s practice for hunting their favorite food, Atlantic bluefin tuna. The study suggests that the young orcas are using the boats’ rudders as targets, mimicking the behavior they use to isolate and tire out tuna before capturing them. This behavior, while concerning for sailors, may be a natural part of the orcas’ playful learning process, which helps them develop the skills needed for successful hunting.
Scientists have documented three instances of orcas preying on sharks in the Gulf of California, raising concerns about the potential impact on the ecosystem. While orcas have always hunted sharks, the recent increase in observations may be due to improved technology, and the long-term consequences remain unclear.
Two recent shark attacks in Florida have sparked rumors linking the incidents to the presence of orcas in the Gulf of Mexico. However, marine biologists dismiss this theory as unsubstantiated. Experts believe the attacks are more likely due to increased human activity and changes in bait fish distribution. Orca sightings are also attributed to the rise in eco-tourism, not a surge in their population.
