How fast can a water moccasin swim?

Water moccasins, also known as cottonmouths, can swim at speeds of about 1 to 2 miles per hour (1.6 to 3.2 kilometers per hour). They are not particularly fast swimmers compared to some other aquatic snakes, but they are agile and can navigate through water effectively. Their swimming technique involves using their bodies in a serpentine motion, allowing them to maneuver around obstacles in their environment.
