If you're an arachnophobic you might want to turn away: this video of a Sicarius (a six-eyed sand spider) rapidly covering itself up might just make you itch!

If the terrifying appearance of this little guy isn't enough to make you cringe, how about the speedy motion of it's legs?

Fear aside, the swift cover up occurs in just fifteen seconds, making the spider go from "now you see me" to "now you don't" in less time than it took you to read this post.

Watch where you're stepping!
