Orcas' puzzling behavior continues with boat attacks.

A pod of at least three killer whales bumped into a boat participating in The Ocean Race as it approached the Strait of Gibraltar. The crew was forced to drop its sails and raise a clatter to scare the orcas off. No one was injured, but the encounter highlights a growing trend of sometimes-aggressive interactions with Iberian orcas. Scientists have noted increasing reports of orcas bumping or damaging boats off the western coast of the Iberian Peninsula in the past four years.
