The Venomous Snakes in the United States
The United States is home to four genera of venomous snakes. These deadly snakes are:
CottonmouthsRattlesnakesCopperheadsCoral Snakes
Each of these snakes is found within the borders of the contiguous U.S., but not all of them are in each state. Some states lack members from this list, while others have numerous species from each genus. The latter is the case with Missouri, as we will show you throughout this article.
How Many Types of Snakes Live in Missouri?
Missouri has 38 different types of snakes that live throughout the state. The vast majority of them are non-venomous and serve an important role in the food chain. They help keep rodent and small mammal populations low and serve as meals for eagles and other animals. Although it might be helpful to have some of these animals in one’s backyard, some snakes are rather unwelcome. After all, Missouri is home to a few species of venomous, sometimes called poisonous, snakes.
The 5 Venomous Snakes in Missouri
The five venomous snakes in Missouri are the copperhead, timber rattlesnake, cottonmouth, western pygmy rattlesnake, and eastern massasauga rattlesnake. All these snakes are pit vipers and share some qualities, such as their triangular heads and cat-like pupils. Every one of these snakes should be considered dangerous. Although some of them are rarely fatal, all of them can cause severe injuries, long-lasting disabilities, and death when they bite humans. We’re going to examine each of these five snakes. We’ll show you what they look like, which one is most dangerous, and other important information.
Southern Copperhead
Copperhead snakes are a common sight in many parts of Missouri. These snakes measure about 2ft on average, and their colors can vary quite a bite. You may find light brown, yellow, or copper colors, but you can also find darker copperheads. Their colors and dark blotches help them blend in with their surroundings. These snakes are frequently stepped on because people have trouble seeing them. The copperhead that lives in Missouri is often called Osage copperhead, but that’s an antiquated designation. This species is not distinct from the southern copperhead. However, this snake is rather dangerous. A bite from this snake requires a trip to the hospital.
Timber Rattlesnake
Timber rattlesnakes are the largest venomous snakes in Missouri, and they can regularly reach 5ft in length. As their name suggests, they are usually found in wooded areas. When a human approaches a rattlesnake, the snake will rattle to scare them away in some cases. However, rattlesnakes do not rattle all the time and they may strike without warning. These snakes have a deadly hemotoxic venom that requires emergency treatment to survive. Most people survive rattlesnake bites with treatment, but disabilities are common.
Cottonmouth
The cottonmouth snake is also called the water moccasin. As one might imagine, cottonmouth snakes are often found near bodies of water. Although some people claim these snakes are aggressive and will chase down humans to bite them, that’s not exactly true. The cottonmouth snake will start a bluff charge to scare away humans so it can ensure its safety. These snakes can deliver a venomous bite that will cause serious harm to people.
Western Pygmy Rattlesnake
Pygmy rattlesnakes are very small venomous snakes, measuring about 2ft at their longest. Although these snakes are rare and can’t make a lot of venom, they’re still worth knowing about. The rattling noise from a pygmy rattlesnake apparently sounds more like a buzzing than a rattling. Also, you’ll notice that despite being short, this snake has a thick body. The pygmy rattlesnake can deliver a medically significant bite that requires treatment.
Eastern Massasauga
Eastern massasaugas are rattlesnakes known for being somewhat rare in Missouri because they live near the shrinking marsh areas. They are dangerous animals, but they are known for being less aggressive than other types of rattlesnakes. These snakes aren’t as long as timber rattlesnakes, but they’re bigger than pygmy rattlesnakes.
How Many People Do Poisonous Snakes in Missouri Kill Each Year?
On average, fewer than one person in Missouri dies as a result of a venomous snakebite each year. Roughly 250 venomous snakebites occur in Missouri each year. Fortunately, the advances in modern medicine largely prevent deaths in the United States. Even though the number of snakebite deaths is low, they can only stay that way with proper education. Do not try to handle snakes that you’re not familiar with, and always go seek medical help if you get a snakebite.
