Turtle fraternity

I looked this up online. From what I have read, it started out as a drinking game between pilots. No, I am not a turtle. The closest I have become to being a turtle was I bought turtle paperweight that had a magnifying glass on the back. I put words of inspiration under the glass. I bought it as a gift for a friend....I also had turtles as pets when I was little...and the bigger ones would hang around my home. That is it. Never even heard of this groups before. Why turtles instead of, say.....chipmunks? What color of long hair does this turtle have? :)
