Black and Yellow Argiope

Well, I decided to research our spider! The size of the spider really does freak me out and I thought that I better find out a little about it! So it is called a Black and Yellow Argiope and they are harmless to humans. But the more I zoomed in on the picture I realized that he has 'faces' or shapes like faces on his back! Creepy - so I am posting the zoomed picture here for you all because it is really neat looking!
