Octopuses are one of those creatures that you can't quite believe are entirely real--they're so sinuous and alien-looking and you just know that if they ever had the chance, they'd come right at you and sucker your face directly off your body. They're also incredibly cool, and very beautiful, and etsy seller OctopusMe says that they're symbols of transformation and regeneration. And they make for some gorgeous, creepy-looking, beautifully organic jewelry, too. Are you weirded out that they're made from die-casting real tentacles? I am, too! But they're still amazing-looking.
