The coachwhip is a long, slender, fast-moving snake of open habitats across the southern United States, named for scale patterns resembling a braided leather whip toward the tail. It is among the fastest-moving snakes in North America, actively hunting rather than ambushing prey.
Coloration varies considerably across its range, from nearly solid black in the east to reddish or tan tones farther west, sometimes leading to confusion with other species.
