Venomous Snakes in Georgia: Identifying the Six Species

Georgia is home to a diverse range of snakes, but not all of them pose a threat. In fact, out of the 41 native snake species in the state, only six are venomous. These venomous snakes include the eastern diamondback rattlesnake, timber rattlesnake, pigmy rattlesnake, cottonmouth, copperhead, and coral snake. Among them, the eastern diamondback rattlesnake stands out as the largest venomous snake in North America, easily identifiable by the distinctive rattle on its tail. Meanwhile, the timber rattlesnake is known for its dangerous reputation, showcasing rattling behavior that serves as a warning sign. The pigmy rattlesnake, though small in size, should not be underestimated as its rattling can be difficult to detect. On the other hand, the eastern coral snake is easily recognizable with its rings of red, yellow, and black, and unique fixed fangs. The cottonmouth, or water moccasin, is semi-aquatic and primarily dwells in freshwater habitats. Lastly, the southern copperhead, commonly found in the metro Atlanta area, accounts for the majority of snakebites in the Southeast. In order to ensure safety, it is crucial to exercise caution and avoid any interactions with venomous snakes in Georgia.

Eastern Diamondback Rattlesnake


The Eastern Diamondback Rattlesnake is the largest venomous snake in North America, reaching lengths of up to 8 feet. It gets its name from the diamond-shaped markings on its back, which are outlined in a lighter color. The coloration of the Eastern Diamondback Rattlesnake can vary depending on its habitat, but it typically ranges from grayish-brown to reddish-brown.

One of the most distinctive features of the Eastern Diamondback Rattlesnake is its rattle on the tail. This rattle is made up of modified scales that vibrate when the snake shakes its tail. It serves as a warning signal to potential threats, letting them know that the snake is nearby.

Habitat and Distribution

The Eastern Diamondback Rattlesnake is found primarily in the southeastern United States, including Georgia. It prefers dry habitats such as pine forests, sandy areas, and coastal dunes. This species is known to adapt well to human-altered environments, making it occasionally found in suburban areas.

Behavior and Venom

The Eastern Diamondback Rattlesnake is typically a docile and non-aggressive snake, but it will defend itself if it feels threatened. When confronted, it will often coil its body into an S-shape, raise its head off the ground, and rattle its tail as a warning sign. If an approaching threat persists, the snake may strike, injecting its venom through its fangs.

The venom of the Eastern Diamondback Rattlesnake is highly potent and can lead to tissue damage, internal bleeding, and in some cases, death if medical treatment is not sought promptly. However, it is important to note that these snakes will usually try to avoid confrontation and only strike as a last resort.

Timber Rattlesnake


The Timber Rattlesnake is one of the most dangerous snakes in North America. It can grow up to 5 feet in length and has a thick body. This snake varies in color, but it commonly has a pattern of dark brown or black crossbands on a lighter background, giving it a highly camouflaged appearance. The head of the Timber Rattlesnake is broad and triangular.

Habitat and Distribution

The Timber Rattlesnake can be found in the northeastern United States, including parts of Georgia. It prefers deciduous forests, rocky hillsides, and areas with abundant cover such as fallen logs or thick vegetation. These snakes are generally more elusive than Eastern Diamondback Rattlesnakes and are not commonly encountered.

Rattling Behavior

The Timber Rattlesnake gets its name from its distinctive rattle, which is located at the end of its tail. When threatened, it will vibrate its rattle, producing a loud buzzing sound. This serves as a warning to potential threats and is an effective means of communication. The rattling behavior is a characteristic feature of Timber Rattlesnakes, helping to distinguish them from non-venomous snakes.

Pigmy Rattlesnake


The Pigmy Rattlesnake is a smaller species of rattlesnake, typically measuring between 1 and 2 feet in length. Despite its small size, it is still venomous and should be approached with caution. The coloration of the Pigmy Rattlesnake can vary, but it generally has a gray or brownish-gray background with a series of dark blotches along its back.

Habitat and Distribution

The Pigmy Rattlesnake is commonly found in Georgia and throughout the southeastern United States. It prefers a variety of habitats, including pine forests, hardwood forests, and swampy areas. These snakes are often encountered in suburban areas with suitable habitat.

Rattling Characteristics

The Pigmy Rattlesnake possesses a small rattle at the end of its tail, but it can be difficult to hear due to its size. Instead of relying solely on rattling to warn potential threats, the Pigmy Rattlesnake will often resort to other defensive behaviors such as remaining motionless or striking without warning. This makes it important to exercise caution when encountering this species.

Eastern Coral Snake


The Eastern Coral Snake is easily identifiable by its distinct red, yellow, and black banding. This color pattern is a warning signal to potential predators, indicating that it is venomous. The bands of color are narrow and consistent, with the red bands being separated by yellow and black bands.

Habitat and Distribution

The Eastern Coral Snake can be found in the southeastern United States, including parts of Georgia. It prefers wooded areas, pine forests, and sandy soils. These snakes are often found in leaf litter or under fallen logs.

Identification Features

One of the key features that distinguishes the Eastern Coral Snake from other venomous snakes is its fixed fangs. Unlike other venomous snakes that have hinged fangs, the Eastern Coral Snake’s fangs are immovable. This means that it must chew or grind its venom into its prey, making it less likely to inject venom into humans. However, it is still considered highly venomous and should be avoided.



The Cottonmouth, also known as a water moccasin, is a venomous snake that is semi-aquatic. It can grow up to 5 feet in length and has a heavy body. The coloration of the Cottonmouth can vary, but it commonly has a dark brown or black body with a lighter-colored belly. When threatened, it will often open its mouth wide, revealing the white interior, hence the name “Cottonmouth.”

Habitat and Distribution

The Cottonmouth can be found in the southeastern United States, including Georgia. It prefers freshwater habitats such as swamps, marshes, and slow-moving streams. These snakes are excellent swimmers and are often seen basking on logs near water.

Semi-Aquatic Behavior

Due to its preference for water, the Cottonmouth is often encountered near bodies of water or in wetland areas. It is a strong swimmer and can be found both on land and in water. While it may appear aggressive when confronted, the Cottonmouth will usually choose to retreat rather than engage with humans. It is important to give this snake a wide berth and avoid provoking it.

Southern Copperhead


The Southern Copperhead is a medium-sized venomous snake, reaching lengths of up to 3 feet. It has a distinctive copper or reddish-brown body with darker-colored crossbands. The head of the Southern Copperhead is broad and has a heat-sensing pit located between the eye and the nostril.

Habitat and Distribution

The Southern Copperhead is commonly found in the southeastern United States, including Georgia. It prefers a variety of habitats, including forests, woodlands, and rocky slopes. These snakes are known for their adaptability and can be found in suburban areas and even urban environments.

Prevalence in Metro Atlanta

The Southern Copperhead is the most frequently encountered venomous snake in the metro Atlanta area. While it is venomous, it is generally regarded as less dangerous compared to other venomous snakes. However, bites from Southern Copperheads can still cause significant pain, swelling, and tissue damage. It is important to be cautious and avoid interactions with this species.

Identifying Venomous Snakes in Georgia

Physical Characteristics

There are several physical characteristics that can help identify venomous snakes in Georgia. These include size, head shape, body coloration, and distinct patterns such as crossbands or rings. Venomous snakes in Georgia tend to have thicker bodies compared to non-venomous snakes, which can be a useful visual clue.

Habitat and Range

Understanding the habitat and range of venomous snakes in Georgia is essential for identification. Certain venomous snake species have specific habitat preferences, such as the Eastern Diamondback Rattlesnake’s affinity for dry areas and pine forests. By familiarizing yourself with the typical habitats of venomous snakes, you can better determine if a snake is potentially venomous.

Distinctive Behaviors

Venomous snakes in Georgia may exhibit distinctive behaviors that can aid in identification. For example, rattling behavior is unique to certain venomous species like the Eastern Diamondback Rattlesnake and Timber Rattlesnake. Other behaviors may include aggressive posturing, such as raising the head off the ground or striking defensively. By observing these behaviors, you can determine if a snake is potentially venomous and take appropriate precautions.

Distinguishing Venomous Snakes from Non-Venomous Snakes

Head Shape

One notable distinction between venomous and non-venomous snakes is the shape of their heads. Venomous snakes usually have a triangular or diamond-shaped head, whereas non-venomous snakes typically have a narrower, more rounded head. The broader head shape of venomous snakes is due to the venom glands located behind their eyes.

Pupil Shape

Another characteristic to look for when distinguishing venomous and non-venomous snakes is the shape of their pupils. Venomous snakes in Georgia, such as the Eastern Diamondback Rattlesnake and Southern Copperhead, have elliptical-shaped pupils. In contrast, non-venomous snakes typically have round pupils. Observing the pupil shape can provide valuable information in determining the potential venomous nature of a snake.

Rattles and Vibrating Tails

Rattling behavior is a notable behavior exhibited by some venomous snakes, such as the Eastern Diamondback Rattlesnake and Timber Rattlesnake. These snakes have specialized scales at the end of their tails that produce a distinct rattling sound when vibrated. This rattling behavior is used as a warning signal to deter potential threats. However, it is important to note that not all venomous snakes have rattles, so relying solely on this characteristic can be misleading.

Safety Precautions

Stay Alert and Aware

When in snake habitats, it is crucial to stay alert and aware of your surroundings. Look out for any signs of snakes, such as rustling in the brush or movement on the ground. Maintaining awareness can help you identify potential hazards and take appropriate precautions.

Keep a Safe Distance

If you encounter a snake, it is essential to keep a safe distance and avoid provoking or engaging with the snake. Most snake bites occur when people attempt to handle or capture snakes, so it is crucial to maintain a respectful distance. Remember, snakes will usually try to avoid confrontation and will only strike if they feel threatened.

Proper Hiking and Outdoor Gear

Wearing appropriate gear can provide an additional layer of protection when exploring snake habitats. Closed-toe shoes or boots can help prevent snake bites on the feet, and long pants can provide a barrier against snake venom. Consider using a walking stick to probe the ground in front of you, allowing you to detect any hidden snakes.

What to Do If You Encounter a Venomous Snake

Remain Calm and Still

If you encounter a venomous snake, it is important to remain calm and still. Panicking or making sudden movements can agitate the snake and increase the likelihood of a defensive response. Remember that most snake bites occur when people provoke or mishandle snakes, so staying calm is crucial.

Back Away Slowly

Backing away slowly is the safest way to disengage from a venomous snake. Avoid turning your back on the snake, as this could trigger a predatory response. Instead, back away while keeping an eye on the snake to ensure it does not approach you.

Seek Medical Attention if Bitten

If you are bitten by a venomous snake, it is essential to seek immediate medical attention. Call emergency services or go to the nearest hospital as soon as possible. Do not try to suck out the venom or use a tourniquet, as these measures are ineffective and can do more harm than good.

By familiarizing yourself with the venomous snake species in Georgia and understanding their habitats, behaviors, and identifying features, you can enhance your safety while enjoying the outdoors. Remember, it is always best to avoid confrontation with venomous snakes and to treat them with respect and caution.
