The Giant Tortoise. If you want a quick and easy way to radically change your understanding of the world, I urge you to google tortoise x-rays. Think there's a little beastie hiding in that shell? There is not. The shell is part of its skeleton and it's been freaking me about for around 4 years now. I mean, I didn't think it was like a hermit crab. Did I? Oh god, maybe I did? Somewhere along the line a cartoon has led me astray.
