I generally stay away from the ocean. I don't trust what's in there. If you think you're safe on a boat, you're crazy. Have you ever seen a ten ton whale breach water? If an underwater behemoth wanted to get you, it'll get you. I don't care what kind of boat you're on. The only way to stay safe is to stay on dry land. Even then, I don't feel completely safe from the creatures of the deep. Don't see my point? Well, let's look at this selfie as evidence then.
That shark is perfectly capable of breaching the water and biting that dude's head off. Hopefully that didn't happen, but this is exactly why you never take your eyes off the water. That's when the creatures will get you. My fear could be wrong, but I'd rather be alive than right.
