That's a good swamp rattler pic, as they are also known, ng. They are venomous. Good story too, Monty. If they would import a bunch of hogs over there, they might take care of the snake problem. TnMts, the coachwhip is a different snake and a member of the racer family. They get their name from the fact that the last 12 feet (joking, they're not that long) of their tail section resembles a braided coach whip. Many harmless snakes will imitate their venomous cousins. A bullsnake will vibrate his tail, and if it happens to be in dry leaves it will get your attention. I have a close up pic of one hissing in such a way that it vibrates in his throat and sounds a lot like a rattler. The best one of all though, and I hope to get a picture some day, are some bullsnakes that do a dead on imitation of a cobra. They raise up, flatten the throat, and sway back and forth. Why they picked up this behavior in North America, I have no idea. Maybe I can get my son to do a research project on it while he's working on his masters. And all y'all: Take no chances with venomous snakes, but if possible give them the right of way. And contrary to popular belief, some of them are NOT more scared of you than you are of them. They don't taste like chicken, either.
