Coachwhip snakes are long and thin, reaching up to 8 feet in length, with the longest ever caught being 8.5 feet long. Their eyes are large, and their heads are smaller than their bodies.

Some rat snakes reach the same length as coachwhips, while a few sometimes exceed it. They’re known to grow up to 9 feet long, and they’re also long and thin snakes.

Coachwhip and rat snakes are some of the longest nonvenomous snakes out there.

Coachwhip vs Rat Snake: Appearance

A coachwhip’s patterning and coloration are what make them stand out. Their tails are white or cream and taper into black as they approach the head. Their coloration will vary by region, but their body’s color always tapers.

Rat snakes are so widespread that they come in various colors, patterns, and tonality. They aren’t as predictable appearance-wise as the coachwhip snake.

They’re called coachwhip snakes because of their unique patterning. The way their scales appear makes them look like braided whips. Braided whips were common among stagecoach drivers who often encountered coachwhip snakes.

Rat snakes live in a huge variety of habitats, and their appearance is as varied as their locations. Their scales may be patterned, and they have upturned noses, but it’s hard to generalize their appearance because it’s encompassing.

Coachwhip vs Rat Snake: Diet

Both snakes have relatively the same diet, but what they eat varies by subspecies and region. Rat snakes and coachwhips enjoy eating lizards, birds, mice, rats, and eggs. Both are notorious nest raiders though rat snakes are the most guilty.

Rat snakes are named that because their favorite prey is rats. While they will chow down on lizards if the situation calls for it, they heavily prefer warm-blooded animals. They’re known chicken killers and raid chicken coops when possible.

Rat snakes are prone to predation at a much higher frequency than coachwhips due to their sizes. Weasels, badgers, coyotes, and other snakes commonly chow down on rat snakes. Coachwhips only need to worry about the occasional apex predator like great-horned owls.

Coachwhip vs Rat Snake: Speed

One of the fastest snakes in the USA is the coachwhip. The coachwhip snake can move at speeds up to 4 mph on land. Rat snakes aren’t famous for moving fast though they’re swift climbers.

While the coachwhip is one of the fastest moving snakes in the United States, the rat snake is one of the fastest striking snakes in the world. This is surprising since they’re nonvenomous and they’re constrictors.

Coachwhip vs Rat Snake: Habitat

Coachwhip snakes are endemic to Mexico and the USA. Specifically, they’re in the southern United States and northern Mexico, a common sight within their territories.

Rat snakes have a larger range, and some rat snakes live in almost every Northern Hemisphere region. They’re more prevalent in Southeast Asia and the Eurasian Continent than the coachwhip.

Coachwhips prefer sandy and loose dirt ecosystems, including coastal dunes, fields, sandhills, pine forests, and prairies. Rat snakes are found in more arid environments but also flourish in farmlands, fields, and rainforests.

Coachwhip vs Rat Snake: Behavior 

The hottest part of the day is the coachwhip’s favorite time for activity. In the winter, they brumate just like the rat snake, and Brumation is a form of snake hibernation.

Rat snakes are also active during the day and constrict their meals, so they crush them to death. Coachwhips are found prowling around with their heads up because they use their keen eyesight to locate prey.

Rat snakes are climbers and spend a lot of their time lounging in trees. In more developed environments, they like the tops of buildings and eaves, and fences and walls are obstacles they will easily overcome.

Coachwhip vs Rat Snake: Are They Dangerous?

Neither the coachwhip nor the rat snake is very dangerous to humans. While bites are possible, both snakes are nonvenomous, so their bites are relatively harmless. Neither snake has fangs.

Coachwhips will stand their ground by biting if their upright posture hasn’t deterred a threat. The rat snake and the coachwhip rattle their tails defensively and release a musk when threatened. Their musk smells foul, and it’s used to disgust predators into retreating.

Rat snakes are commonly found in gardens and shouldn’t cause alarm. They’re considered non-aggressive. Coachwhips will attack when cornered more readily than a rat snake, and their bite is painful since they have tiny teeth.
