Minnesota’s Hidden Danger: Types of Venomous Snakes You Should Know About

Minnesota's Venomous Snake Species

When most people think of venomous snakes, they likely picture the deserts of the Southwest or the swamps of the Southeast. However, they can be found in unexpected places, including Minnesota. While Minnesota is not known for having a high population of venomous snakes, there are still a few species that can be found in the state. It’s important for residents and visitors to be aware of them and their characteristics in order to stay safe and avoid potential encounters.

In this article, we will explore the types of venomous snakes found in Minnesota, including their physical characteristics and habitats. We will also provide tips on how to avoid snake bites and what to do if you encounter a venomous snake. Whether you’re an avid hiker or simply curious about the wildlife in your area, this guide will provide valuable information on the venomous snakes of Minnesota.

The Timber Rattlesnake

Timber Rattlesnake

The Timber Rattlesnake (Crotalus horridus) is one of the two venomous snakes found in Minnesota. It is typically a grey-brown or reddish-brown snake with dark bands running along the body and a distinct diamond pattern on its head. Its rattle, which can be heard from up to 25 feet away, gives it its name.

The Timber Rattlesnake is an important species in the Minnesota environment, so let’s learn more about it and its characteristics.

Physical characteristics

Understanding the physical characteristics is essential in identifying and avoiding them if you encounter them in the wild.

The Timber Rattlesnake has a triangular-shaped head, a thick and heavy body, and a rattle at the end of its tail that produces a distinctive sound when the snake feels threatened. The snake’s body coloration depends on the habitat it lives in, but it usually ranges from yellowish-brown to dark brown with dark-colored crossbands. The Eastern Massasauga, on the other hand, has a stout, grayish-brown body and a distinctive head pattern characterized by two dark stripes that run through its eyes.

Remember that both snakes are venomous and can cause harm to humans if provoked, so it’s essential to give them their space and let them continue on their way.

Habitat and distribution in Minnesota

Habitat: Timber rattlesnakes prefer deciduous forests, rocky outcroppings, and open prairies with ample sunlight. They can also be found near streams and wetlands.

Distribution: It has a documented range extending from southeastern Minnesota to the east-central portion of the state. However, they are considered rare and elusive, with only a few sightings reported every year. 

If you come across a Timber Rattlesnake or any other venomous snake, it is best to give them space and let them be. These snakes play an essential role in maintaining the ecological balance of their habitats.

Behavior and diet

While the timber rattlesnake may seem like a dangerous predator, it actually plays an important role in its ecosystem by controlling populations of rodents and other small animals.

The timber rattlesnake is a carnivorous species, feeding primarily on small mammals such as mice, rats, and squirrels. They are also known to eat birds and amphibians. Their hunting strategy involves waiting in a coiled position until prey comes within striking distance, at which point they use their venomous bite to immobilize and kill the animal.

In addition to their hunting behavior, timber rattlesnakes also play a role in regulating the behavior of other animals in their ecosystem. Studies have shown that the presence of rattlesnakes can actually reduce the activity of rodents, which can help prevent damage to crops and other vegetation.

While the timber rattlesnake can be dangerous to humans if provoked or threatened, they generally prefer to avoid confrontation and will only attack if they feel threatened. It’s important for hikers and outdoor enthusiasts to be aware of the presence of timber rattlesnakes in their area and to take precautions such as wearing appropriate footwear and staying on designated trails. By understanding the behavior and diet of the timber rattlesnake, we can better appreciate the role this species plays in our ecosystem and take steps to ensure their conservation.

The Eastern Massasauga

Eastern Massasauga

The Eastern Massasauga is a species of venomous snake found in Minnesota. It is a small rattlesnake that can grow to a maximum length of two feet. It is recognized by its triangular head and dark brown, black, or grey coloration. It can be distinguished from other species by its blunt tail and small rattle.

It inhabits the open wetland areas of Minnesota and has a preference for dry soils.

Let’s take a closer look at Eastern Massasauga.

Physical characteristics

The Eastern Massasauga is native to Minnesota and is characterized by its distinctive physical features.

Here are some defining characteristics of Eastern Massasauga:

Size: Adults typically range from 2 to 3 feet in length, making them relatively small among these types of ophidians.

Color: Their skin color ranges from grayish-brown to reddish-brown, with a series of dark brown spots lined along their backs in a row.

Rattles: One of the most unique features is the rattle at the end of their tails. When threatened, the rattlesnake shakes its tail, creating a buzzing sound to ward off predators.

Scale pattern: They have keeled scales, which are rougher in texture, and a series of vertical lines on their faces known as loreal scales.

Habitat and distribution in Minnesota

This snake is typically found in wetland habitats, such as marshes, swamps, and bogs, where they can hunt for their prey and find shelter. They are also known to inhabit adjacent upland areas, including grasslands and forests.

In Minnesota, the Eastern Massasauga is found primarily in the southeastern part of the state, where there are suitable wetland habitats for the species. They are also found in some parts of the central and western regions of the state, although their populations are much smaller in these areas.

The distribution of the Eastern Massasauga in Minnesota is somewhat limited due to habitat loss and fragmentation. Wetland habitats, in particular, have been impacted by human activities such as drainage and development, which can make it difficult for the species to find suitable habitats and prey.

Conservation efforts are underway in Minnesota to protect and manage Eastern Massasauga populations. These efforts include habitat restoration and management, as well as public education and outreach to help people understand the importance of this species and how to avoid encounters with them. By preserving suitable habitats and taking steps to protect the Eastern Massasauga, we can ensure that this important species continues to thrive in Minnesota.

Eastern Massasauga

Behavior and diet

Despite its venomous nature, the Eastern Massasauga is a shy and elusive species that generally avoid confrontation with humans.

Like other species of snakes, the Eastern Massasauga is a carnivorous species that feeds primarily on small rodents such as mice and voles. They are also known to eat small birds and amphibians. Their hunting strategy involves waiting in a coiled position until prey comes within striking distance, at which point they use their venomous bite to immobilize and kill the animal.

While the Eastern Massasauga can be dangerous to humans if provoked or threatened, they generally prefer to avoid confrontation and will only attack if they feel threatened. It’s important for hikers and outdoor enthusiasts to be aware of the presence of Eastern Massasaugas in their area and to take precautions such as wearing appropriate footwear and staying on designated trails.

The Eastern Massasauga plays an important role in its ecosystem by controlling populations of rodents and other small animals. It also serves as prey for larger animals such as birds of prey and other snakes. By understanding the behavior and diet of the Eastern Massasauga, we can better appreciate the role this species plays in our ecosystem and take steps to ensure their conservation.
