Scientists have a new theory to explain why orcas are ramming yachts in the Iberian Peninsula — the boats are practice targets for learning to hunt their favorite food.
When young Iberian orcas (Orcinus orca) started hitting and sinking boats in 2020, experts wondered whether it was revenge, accidental, or just a fun thing to do. But the new theory suggests the juvenile orcas might be using the boats' rudders as targets to practice hunting Atlantic bluefin tuna (Thunnus thynnus).
