I saw this on the road from Botany to the highway. I would think such a distinct pattern would be easy to ID, but I don't see it in my limited book. I have decided it's a cottonmouth water moccasin because of it's fat middle. They are our most poisonous snake. My pals agree that's what it is. My book shows them as very dark, but this one is only between three and four feet long, so may be rather young and hasn't turned dark yet
I stopped perhaps 12-15 feet from it. When I got out of the car, it let me take several pictures without moving at all.

But when I came out from behind the car door and took a step closer, it turned around very fast and went back the way it had come with tongue wagging the whole way.
They can be very aggressive so I was stepping very gingerly and in turn-and-run mode. I'm glad it went away rather than toward me. It was so fat--maybe it had eaten recently so wasn't feeling mean.
