You know what's really funny? The actually have paper that can get soaking wet and stay unaffected. The only kind I've seen is the "Rite-in-the-Rain" green paper the military uses. So I'm guessing that there's a kind of "rite-underwater" variety out there....that sharks can use...after they get it off of Amazon.
It's always a little funny to me when people talk about how gentle and benign Orcas are.
But here's the thing; Orcas are apex predators, without a doubt one of the most effective hunters on earth, and it's only really because of their good nature that we don't see more casualties when dealing with them. Don't get me wrong, they're beautiful, fascinating animals, but in the end, there's nothing stopping them from ripping you apart.
I always get annoyed by people telling me that orcas are so cute and loveable. Free Willy and such. ...These fuckers are the trolls of the ocean. They can kill everything and even a great white shark or giant blue whale are no match for them (i have seen some spectecular footage of orcas hunting and killing those)
