North Carolina boasts a diverse ecosystem, and its waterways are home to several species of water snakes. These often-misunderstood reptiles play a crucial role in the state's environment, but understanding their characteristics can help prevent unnecessary fear and ensure their protection. This guide explores the various water snakes found in North Carolina, their habitats, behaviors, and the best ways to co-exist peacefully.
What Types of Water Snakes Live in North Carolina?
North Carolina is home to several species of water snakes, each with unique characteristics. The most common include:
-
Northern Water Snake ( Nerodia sipedon): This is arguably the most prevalent water snake in North Carolina. They are highly variable in color and pattern, ranging from dark brown or black with darker crossbands to reddish-brown or olive with lighter markings. Their broad heads, relatively stout bodies, and keeled scales are key identifying features.
-
Brown Water Snake (Nerodia taxispilota): Often mistaken for the Northern Water Snake, the Brown Water Snake tends to have a more uniform brown coloration with darker blotches or saddles. They inhabit slower-moving waters and are frequently found basking on logs or rocks near the water's edge.
-
Banded Water Snake (Nerodia fasciata): Distinguished by its striking pattern of dark crossbands on a lighter background, the Banded Water Snake is a relatively large species. They prefer larger rivers and lakes.
-
Queen Snake (Regina septemvittata): This smaller water snake is typically olive-brown or gray, with darker stripes running along its body. They are less commonly seen than other water snake species and are found in clearer, cooler streams and rivers.
-
Cottonmouth ( Agkistrodon piscivorus): While technically a viper and not a water snake in the strictest taxonomic sense, it’s crucial to mention cottonmouths due to their semi-aquatic lifestyle and prevalence in North Carolina. Their dark, often black, bodies and distinctive heat-sensing pits are key identifiers. Importantly, cottonmouths are venomous.
Are Water Snakes Dangerous?
While many people fear water snakes, most species are harmless to humans. They are not aggressive and will usually flee at the first sign of danger. They primarily feed on fish, amphibians, and other small aquatic creatures. However, it's essential to remember the exception: Cottonmouths are venomous and should be avoided. If you encounter a cottonmouth, slowly back away and give it space.
How Can I Tell the Difference Between a Water Snake and a Cottonmouth?
Distinguishing between harmless water snakes and venomous cottonmouths is vital. Here are some key differences:
- Pupil Shape: Cottonmouths have elliptical pupils, while most water snakes have round pupils.
- Head Shape: Cottonmouths have a triangular, broader head, whereas water snakes generally have a more slender, elongated head.
- Body Shape: Cottonmouths have a more robust, heavier body than most water snakes.
- Coloration: While coloration is variable and not always reliable, the overall appearance can be a clue. Cottonmouths often display a dark, almost black, coloration.
Caution: It's best not to rely solely on visual identification. If you are unsure, assume it is a venomous snake and maintain a safe distance.
What Should I Do If I See a Water Snake?
If you encounter a water snake, the best course of action is to observe it from a safe distance and leave it alone. Do not attempt to handle it, even if it appears harmless. Water snakes play a vital role in the ecosystem, and unnecessary disturbance can disrupt their natural habitat.
What Eats Water Snakes?
Water snakes are prey for a variety of animals, including larger snakes (like other species of water snakes), birds of prey, and even certain mammals like raccoons and opossums. Their role in the food chain contributes to the balance of the North Carolina ecosystem.
Are Water Snakes Protected in North Carolina?
Most water snake species are not currently listed as endangered or threatened in North Carolina. However, protecting their habitats through responsible land management and conservation efforts remains crucial to ensuring their continued survival. Unnecessary killing of these harmless snakes should be avoided.
