The red racer is among the fastest snakes in North America.

The red racer, also known as the red coachwhip, is a subspecies of the coachwhip or whipsnake. The name should give you some idea of how fast they are. These snakes race along the ground with surprising speed when running away from threats or hunting for food. They are thought to be active during the day, basking near roads. They are not venomous and are generally considered to be harmless to humans.

4 Red Racer Snake Amazing Facts

  • The red racer is thought to mate each year in May and lay a clutch of four to 20 eggs in the early summer. The eggs hatch after about 45 to 70 days. The small newborn whipsnakes have no other associations with their parents after hatching from the eggs.
  • The red racer is thought to have a normal lifespan of 13 years in the wild and 20 years in captivity.
  • The red racer is able to climb both trees and bushes with surprising skill.
  • Like all other snakes, the red racer has an organ located on the roof of the mouth that senses odor from the air. When the snake flicks out its tongue, it draws the scent molecules into its mouth.

Where to Find Red Racer Snakes

The red racer can be found in deserts, grasslands, shrublands, and rocky, sandy hills throughout the southwestern United States and northwestern Mexico. They prefer areas where the vegetation isn’t too dense and their speed provides a natural advantage. Red racers take refuge in burrows, rocks, vegetation, trees, and other objects. Below is a list of the American and Mexican states where they can be found. They do not exist as far to the east as New Mexico and Colorado.

Scientific Name

The scientific name of the red racer is Masticophis flagellum piceus. Masticophis means tail whip in Greek. Flagellum also means whip or scourge in Latin. Piceus means pitch black in Latin as well. The red racer is one of six subspecies of the coachwhip snake along with the eastern coachwhip, western coachwhip, Sonoran coachwhip, and others.

Red Racer Snake Population & Conservation Status

The red racer whipsnake has not been evaluated by the IUCN Red List for its conservation status, but the coachwhip species, in general, is classified as least concern. Numbers appear to be very high and stable. This subspecies faces no particular threats in the wild, but they do sometimes fall victim to road accidents.

Appearance & Description

The red racer is a long, slender snake, generally measuring anywhere between 3 and 5.5 feet long. The body has a smooth braided appearance that resembles the whip of a coachman, giving the species its common name. It is often said to have a banded or saddled pattern with dark red or black blotches spaced regularly along the lighter red-colored body, although black and yellow morphs are also known to exist. The color scheme is thought to aid with camouflage in its natural habitat. Baby and juvenile red racers look similar to the adults, but the body may be more of a light brown or more tan than red. This species is sometimes confused with the San Joaquin coachwhip from central California and the western coachwhip from the other side of Colorado and New Mexico, but their range tends not to overlap very much.



Here is how to identify the red racer snake:

  • Long, slender body measuring up to 5.5 feet
  • Smooth scales
  • Large scales above the eyes
  • Light brown, pink, or red body with regular dark blotches on the back

Red Racer Snake: How Dangerous Are They?

The red racer does not have the ability to produce any venom. They are generally considered to be harmless to humans. If bitten, however, you may experience some minor pain, swelling, and bleeding. You should wash out the wound with soap and water to prevent an infection. Medical attention is rarely required to deal with the bite unless the wound fails to heal properly. There are definitely more dangerous species to worry about, but anyone who spends some time out in the wilderness of southern California, Nevada, Utah, or Arizona might want to be a little wary of this red-belly snake.

Red Racer Snake Behavior and Humans

The red racer is known to be quite skittish around people. If threatened, they may try to coil up and vibrate their bodies to scare away a potential predator by mimicking a rattlesnake. If that fails, they will also try to run away and hide under a nearby object or up a tree with surprising speed. Only when directly cornered or threatened will they attempt to lash out and bite at you. Because they’re difficult to tame, red racers are generally not kept or sold as pets. They do not respond well to being handled and may bite out of self-defense. If you are interested in acquiring a pet snake, then you might want to find a tamer species.
