Hay bị nhầm với: It is often confused with harmless watersnakes (Nerodia) and other semi-aquatic snakes that share its habitat. The Florida cottonmouth has a longer tail, with a relative tail length of about 17.4% in adult and subadult males. Its head markings are lighter, cleaner and more sharply defined, even in older snakes.1
