Rising Killer Whale Attacks on Boats Baffle Researchers.

A pod of orcas severely damaged a yacht off the coast of Spain, destroying the rudder and piercing the hull, forcing the crew to make a Mayday call for assistance. One of the sailors urged people not to "demonize" the marine animals. The attacks are increasingly common, and scientists are examining the recent phenomenon of orcas attacking boats in the Iberian peninsula. One theory suggests that one female orca named White Gladis may have experienced a traumatic event that triggered a change in her behavior to attack sailboats.
