Utah is home to a variety of snakes, some of which are venomous and potentially dangerous to humans. Understanding the types of poisonous snakes in Utah and their behavior can help prevent snake bites. Also, it can keep you and your family safe. It is important to learn about them no matter if you live in the state or not.
Poisonous Rattlesnake Species in Utah
The three types of venomous snakes found in Utah are the Western rattlesnake, the Mojave rattlesnake, and the Great Basin rattlesnake. The Western rattlesnake is the most common of the three and is found throughout the state, while the Mojave rattlesnake is primarily found in the southwestern part of Utah. The Great Basin rattlesnake is found in the northern and central parts of the state.
All three types of rattlesnakes have distinct rattle tails and can be identified by their diamond-shaped heads and vertical pupils. However, it is important to note that not all rattlesnakes rattle before striking, and some may even strike without warning. Therefore, it is crucial to give all snakes a wide berth and avoid handling them.
1. Western Rattlesnake

This is the most widespread of the three rattlesnake species in Utah. It can be found in a variety of habitats, including deserts, forests, and grasslands. Western rattlesnakes have a distinctive rattle on their tail, which they use to warn potential predators or humans of their presence. Their venom is a mixture of toxins that can cause a range of symptoms, from pain and swelling to paralysis and even death. Western rattlesnakes typically eat small mammals, birds, and lizards.
2. Mojave Rattlesnake

The Mojave rattlesnake is found primarily in the southwestern part of Utah, in areas with hot and dry climates. It is known for its potent venom, which contains neurotoxins that can cause respiratory failure and death in humans. Mojave rattlesnakes have a more muted rattle on their tail than other species of rattlesnakes, and may not always rattle before striking. They typically eat small rodents and lizards.
3. Great Basin Rattlesnake

This rattlesnake lives mostly in the northern and central parts of Utah. It prefers high-altitude habitats such as mountains and sagebrush plains. They are the smallest of the three rattlesnake species found in Utah, with an average length of 2-3 feet. Great Basin rattlesnakes have a relatively mild venom that can cause pain, swelling, and tissue damage, but is rarely fatal to humans. They primarily eat small mammals such as rodents and rabbits.
4. The Coral Snake

In addition to rattlesnakes, Utah is also home to the coral snake, a species of venomous snake with bright red and yellow stripes. Although coral snakes are relatively rare in Utah, their venom is highly potent and can cause muscle weakness, respiratory failure, and death. If you come across a coral snake in Utah, do not handle it and seek medical attention immediately if bitten.
Rattlesnake Poison
The venom of rattlesnakes is primarily used for hunting and immobilizing prey, but it can be lethal to humans. The symptoms of a rattlesnake bite may include pain, swelling, and discoloration around the bite, as well as nausea, vomiting, and difficulty breathing. In severe cases, a rattlesnake bite can lead to tissue damage, organ failure, and even death.
