The Red Diamond Rattlesnake is a fascinating and venomous reptile that is native to the southwestern United States and northern Mexico.

Known for its striking coloration and distinctive diamond-shaped markings, this species is a popular subject for herpetologists, nature enthusiasts, and wildlife photographers. In this article, we’ll take a closer look at the physical characteristics, taxonomy, behavior, and interactions of the Red Diamond Rattlesnake, as well as its traditional use and conservation status.

Definition of the Red Diamond Rattlesnake

The Red Diamond Rattlesnake, also known as the Mojave Rattlesnake or Mojave Green, is a venomous pit viper that belongs to the family Viperidae.

It is one of several species of rattlesnake found in the Mojave Desert and surrounding regions of the southwestern United States and northern Mexico. The Red Diamond Rattlesnake is known for its distinctive diamond-shaped markings, which are usually a light green or yellow color with dark borders. Its venom is highly toxic and can cause serious injury or death to humans and other animals.

Physical Characteristics

Red Diamond Rattlesnakes are large, heavy-bodied snakes that can grow up to 5 feet in length.

They have a triangular-shaped head, with two large fangs that can fold back into the roof of the mouth when not in use. Their bodies are covered in overlapping scales that provide protection from predators and help them to retain moisture in their arid environment.

The diamond-shaped markings on their skin are usually a light green or yellow color with dark borders, and are sometimes accompanied by dark spots or bands. The tail is tipped with a rattle, which is used as a warning signal to potential predators.

Range and Habitat

The Red Diamond Rattlesnake is found primarily in the Mojave Desert region of the southwestern United States, including parts of California, Nevada, Utah, and Arizona.

It is also found in parts of northern Mexico, including the states of Sonora, Chihuahua, and Baja California. Red Diamond Rattlesnakes are typically found in rocky, arid habitats such as desert scrub, rocky canyons, and washes. They are also known to inhabit areas near water sources such as streams and springs.


Scientific Classification

The Red Diamond Rattlesnake is classified within the genus Crotalus, which contains over 30 species of rattlesnake. It is also part of the family Viperidae, which includes pit vipers and other venomous snakes. The scientific name of the Red Diamond Rattlesnake is Crotalus scutulatus.

Subspecies and Variations

There are several recognized subspecies and color variations of the Red Diamond Rattlesnake, including the Arizona Red Diamond Rattlesnake, the New Mexico Red Diamond Rattlesnake, and the Western Mojave Rattlesnake. These subspecies vary in their distribution, coloration, and other physical characteristics.

Behavior and Ecology

Diet and Behavior

The Red Diamond Rattlesnake is a carnivorous predator that feeds on a variety of small animals. Its diet mainly consists of rodents such as rats, mice, and ground squirrels. It may also consume birds, lizards, and other small mammals. The snake is known for its excellent hunting skills, which allow it to capture prey efficiently.

The Red Diamond Rattlesnake is typically active during the day, especially in the morning and late afternoon. However, during the hot summer months, it may become nocturnal to avoid the scorching heat. These snakes are also more active during the rainy season, when there is an abundance of prey.

Like most rattlesnakes, the Red Diamond is a solitary creature that prefers to be left alone. It will only attack if it feels threatened or cornered. When it encounters a potential predator or prey, the snake will coil up and strike if necessary. The rattle on its tail is used as a warning sign to let predators or other animals know to stay away.


The Red Diamond Rattlesnake can be found in a variety of habitats, including deserts, scrublands, and grasslands. They prefer rocky areas with plenty of crevices and cover to hide in. They can also be found in woodland areas, especially those with rocky outcroppings and a good supply of prey.

In the United States, the Red Diamond Rattlesnake can be found in the southwestern states of Arizona and New Mexico. They are also found in Mexico, particularly in the northern states of Chihuahua and Sonora.

Conservation Status

The International Union for the Conservation of Nature lists the Red Diamond Rattlesnake as a species of “least concern” (IUCN). This indicates that the species is safe from extinction at the present time. However, they are vulnerable to illegal hunting and poaching as well as the loss and destruction of their natural habitat.


The Red Diamond Rattlesnake is a fascinating and beautiful creature that plays an important role in the ecosystem. While they can be dangerous if provoked, they are generally not aggressive and prefer to be left alone. It is important to remember that these snakes are an important part of our natural world and should be treated with respect and caution. If you encounter a Red Diamond Rattlesnake in the wild, it is best to observe it from a safe distance and allow it to go about its business.
