Yes, water moccasins, also known as cottonmouths, are venomous snakes. They are a species of pit viper native to southeastern parts of the United States, primarily found in or near bodies of water such as swamps, marshes, and streams.

Water moccasins have a venomous bite and are considered one of the venomous snakes in North America. If bitten by a water moccasin, it is important to seek immediate medical attention, as their venom can cause significant pain, swelling, tissue damage, and other complications.

Water moccasins are named for the white coloration on the inside of their mouths, which they often display as a defensive behavior, giving the appearance of “cottonmouth.”

It’s essential to exercise caution and avoid provoking or handling water moccasins or any other venomous snake if you are untrained. If you encounter a water moccasin or suspect you have been bitten by one, it is advisable to contact local authorities or seek medical help immediately.
