Increasing Orca Attacks on Boats off Spain and Portugal Baffle Scientists

Orca encounters with boats are happening frequently off the coasts of Spain and Portugal, with at least one incident reported every day on average. Rui Alves' website, orcas.pt, tracks these sightings and attacks. The reason for the orcas' behavior is unclear, but some experts suggest they may just want to play. However, these apex predators should not be underestimated, as they have been known to hunt great white sharks and blue whales. It is important to follow safety rules and never enter the water with them.
