I looked them up on Wikipedia, they showed a picture of a tiny one with a coin that was only 15mm in diameter. Then I saw the picture with her on your hand. How big was she when you got her? How big is she now? Where did you get her?
I'm fascinated, and love to look at everyone's pictures. One of my boys is rather afraid of spiders, though he's calmed down about other insects. He's the first to ask to get our hognose out though!
