To be honest, I don´t like Orcas and mostly because I am afraid of them. I would maybe cage dive with a great white, but never with an Orca. They are so smart and have such a strong predator instinct, it would find a way to break the cage or something.
Check out this article looking at how precise and targeted their killing and ¨butchering¨ is and who would win in a fight Orca vs Great White.
Trust no one- not even an Orca.
