The water moccasin, also known as the cottonmouth or Agkistrodon piscivorus, is a venomous snake found in the southeastern United States. It is a member of the pit viper family and is known for its aggressive behavior when threatened. Identifying a water moccasin can be challenging, but there are several distinctive characteristics that can help you recognize one.
Physical Characteristics
Water moccasins are relatively large snakes, typically growing to an average length of 20-40 inches (50-100 cm). They have a stout, muscular build and a broad, flat head with a distinctive pit between their eyes and nostrils. The pit is a small depression that is highly sensitive to heat and helps the snake detect warm-blooded prey. The eyes are elliptical and vertical, with a golden or yellowish color. The body is generally dark in color, ranging from black to dark brown, with a distinctive pattern of crossbands or blotches that may be darker or lighter than the surrounding skin.
Color Patterns and Variations
Water moccasins can exhibit a range of color patterns and variations, depending on their age, sex, and geographic location. Young snakes, or juveniles, tend to have a more vibrant pattern with darker crossbands and a lighter background color. As they mature, the pattern may fade, and the background color may become darker. Some water moccasins may also have a distinctive white or yellowish color on the inside of their mouths, which they will often display when threatened or excited. This coloration is thought to be a warning signal to potential predators.

Habitat and Behavior
Water moccasins are found in a variety of aquatic habitats, including swamps, marshes, and slow-moving streams. They are excellent swimmers and can often be seen swimming or basking in the sun on logs or rocks. They are carnivorous, feeding on a range of prey including fish, frogs, and small mammals. Water moccasins are generally solitary animals and only come together during the mating season.
Aggressive Behavior
Water moccasins are known for their aggressive behavior when threatened or cornered. They will often vibrate their tails, flatten their bodies, and display their white or yellowish mouth color as a warning signal. If provoked further, they may strike, injecting their venom into the victim. It’s essential to exercise caution when interacting with water moccasins, as their venom can be deadly to humans.
Some key characteristics to look out for when identifying a water moccasin include their distinctive pit, dark coloration, and aggressive behavior. By being aware of these characteristics, you can better recognize and avoid water moccasins in the wild.
What should I do if I encounter a water moccasin in the wild?
+If you encounter a water moccasin in the wild, it's essential to exercise caution and keep a safe distance. Avoid approaching or handling the snake, as this can provoke an attack. Instead, slowly and carefully back away from the snake, giving it a clear path to escape. If you are in a situation where you cannot safely retreat, try to remain still and avoid sudden movements, which can trigger an attack.
How can I distinguish a water moccasin from a non-venomous snake?
+To distinguish a water moccasin from a non-venomous snake, look for the distinctive pit between the eyes and nostrils, as well as the snake's dark coloration and aggressive behavior. Non-venomous snakes, such as the northern water snake or the brown water snake, lack the pit and tend to have a more slender build. Additionally, non-venomous snakes are generally less aggressive and will not display the same warning signals as a water moccasin.
In conclusion, identifying a water moccasin requires a combination of knowledge about their physical characteristics, habitat, and behavior. By being aware of these factors, you can better recognize and avoid water moccasins in the wild, reducing the risk of a potentially deadly encounter.
