Rising Orcas Attacks on Boats in Europe: Scientists Investigate the Cause

Orcas off the Iberian coast have sunk three boats in seemingly coordinated ambushes, leading scientists to believe the attacks may be revenge for a traumatic incident with a female orca. The orcas strike the rudder or hull of the boats, causing minimal physical damage in most interactions. The behavior may be caused by factors like loss of prey or natural curiosity. If the situation continues, it could become a concern for the safety of sailors and the endangered orcas.
