#7: Never Trust an Octopus
If you asked me what the scariest undersea creature is, I’d ask what you meant by “scariest.” Obviously, if Jaws has taught us anything, it’s that sharks can be pretty darn terrifying if they get it into their head to bite you. But sharks aren’t the only thing to be afraid of in the deep blue…

If you’re asking what animal makes me the most uneasy, it’s definitely octopuses and squids; there is something about the way they move that just weirds me out. And this fact just makes them even creepier: each one of those creepy octopus arms has a brain in it.
