East Tennessee's diverse ecosystem harbors several species of venomous snakes, making awareness and caution crucial for residents and visitors alike. Understanding these snakes, their habitats, and how to react to encounters is vital for safety. This guide will provide comprehensive information on the venomous snakes found in the region, addressing common questions and concerns.
What are the types of venomous snakes in East Tennessee?
East Tennessee is home to several venomous snake species, primarily from the pit viper family (Crotalinae). The most common venomous snakes you'll encounter include:
-
Copperheads ( Agkistrodon contortrix): These snakes are relatively small to medium-sized, featuring a distinctive copper-colored head and hourglass-shaped brown or reddish-brown crossbands on a light brown or tan body. They are ambush predators, often found in rocky areas, wooded hillsides, and near water sources. Copperheads are generally shy and will avoid confrontation, but a defensive bite is a possibility if threatened.
-
Timber Rattlesnakes (Crotalus horridus): Larger than copperheads, timber rattlesnakes possess a thick body with a dark brown or grayish-brown background marked by dark brown or black crossbands. They have a characteristic rattle at the end of their tail, though young snakes may not have a fully developed rattle. These snakes prefer rocky areas, wooded hillsides, and mountain slopes. Timber rattlesnakes are more likely to bite if threatened or cornered.
-
Cottonmouths/Water Moccasins (Agkistrodon piscivorus): These semi-aquatic snakes are robust and have a dark brown or black body, often with dark crossbands. Their defining characteristic is their white or pale mouth lining, visible when they feel threatened. Cottonmouths inhabit swamps, marshes, rivers, and other water bodies. They are more aggressive than copperheads and are more likely to strike if approached. While found in East Tennessee, their distribution is more concentrated in the lower, wetter areas.
Are there other venomous snakes besides the pit vipers?
While pit vipers are the most common venomous snakes in East Tennessee, it's important to note that the coral snake (Micrurus fulvius) also has a venomous bite, but its range is limited and encounters are rare in the region. Coral snakes are small, slender snakes with bright red, yellow, and black bands. Their venom is potent neurotoxin, but bites are infrequent due to their secretive nature and elusiveness.
How can I identify a venomous snake in East Tennessee?
Identifying venomous snakes requires careful observation. Key features include:
- Triangular-shaped head: Venomous snakes, particularly pit vipers, have a distinct triangular-shaped head, broader than their neck.
- Heat-sensing pits: Pit vipers possess heat-sensing pits between their eyes and nostrils, which are visible upon close inspection.
- Vertical pupils: Venomous snakes in East Tennessee have elliptical or vertical pupils, unlike the round pupils of most non-venomous snakes.
- Rattles (for Timber Rattlesnakes): The presence of a rattle is a clear indicator of a timber rattlesnake, although, as mentioned earlier, young snakes may have underdeveloped rattles.
Important Note: Never handle a snake you suspect is venomous. Positive identification is often challenging, even for experienced herpetologists, and a misidentification can have serious consequences.
What should I do if I encounter a venomous snake?
The best course of action when encountering a venomous snake is to remain calm and give it space. Avoid sudden movements and slowly back away. Do not attempt to handle, kill, or provoke the snake. If bitten, seek immediate medical attention. Remember to note the snake's appearance (if possible and safe to do so) for accurate treatment.
What is the best way to prevent snake bites in East Tennessee?
Prevention is key when it comes to snake bites. Here are some precautions:
- Wear appropriate footwear: Wear sturdy boots and long pants when hiking or walking in areas where snakes are common.
- Be aware of your surroundings: Pay close attention to where you are stepping and reaching, especially in tall grass or brush.
- Keep pets leashed: Dogs and cats are often bitten when exploring areas where snakes might be present.
- Secure your yard: Keep tall grass and brush trimmed, and remove piles of rocks, wood, and debris that snakes might use for shelter.
By understanding the venomous snakes of East Tennessee and taking appropriate precautions, you can significantly reduce your risk of encountering a dangerous situation. Remember, respect for wildlife is key to ensuring both your safety and their survival.
