This is one of our longest snakes. It is dark brown or black from the head back over half the length of the snake. The rest of the snake is tan or light brown. Some specimens in our area are totally black. Because it is fast-moving and thrashes about when captured, some people believe coachwhips can whip a person to death. This is a myth. The coachwhip will bite to defend itself and may vibrate its tail when alarmed.
