There was recently 2 boats off Spain that were attacked by killer whales, 1 boat damaged enough that the 2 people needed to be rescued.
Interesting. After watching the NG series, and seeing just how spooky smart orcas are, I'd wonder what the reason's were for the attack. Maybe the boats did something to cross a line with that particular pod? The gist of the NG program was that orcas and other whales actually have "cultures" in that they pass down learned hunting and other behaviors from generation to generation. I'd be willing to bet if they wanted to eat those people they'd have figured out how to get them in the water. Another group of orcas in Antarctica, have developed a cooperative method of tipping seals off ice floes by producing large bow waves. Again, spooky smart.
