Sailor tells how orcas attacked his boat off the coast of Tangier, Spain. Video shows how three orcas emerge from the depths and stealthily approach the stern of the boat.
In a coordinated manner, two of them are directed bluntly to the two rudders, located on port and starboard. So far, there have been more than 300 attacks on boats off the Spanish coast. "I had never seen anything like this, acting with that aggressiveness," says the sailor.
