8. Northern water snake (Nerodia sipedon)
Northern water snake ranks 8th in our list of most common snakes in America. It is native snake species to the North American continent with the range of habitat throughout the whole eastern part of the US. As the name suggests, these snakes dwell around water bodies, including rivers, creeks, marshes, etc. They are non-venomous snakes that are usually being confused with cottonmouth snake, which is why a lot of these snakes end up being killed, since they are very common and frequently encounter humans. They are usually brown or grayish colored with crossbands and patches of bit lighter color. They are rather long, with the average body length of around 130 centimeters.
