Nerodia floridana, commonly known as the Florida green watersnake, or eastern green watersnake, is a harmless species of snake in the subfamily Natricinae of the family Colubridae. The species is native to the southeastern United States.

N. floridana is the largest watersnake in North America. Fully grown it will typically reach 76–140 cm (30–55 in) in total length (including tail), with the record-sized specimen having measured 188 cm (74 in) in total length. Its coloration is solid grey or greenish-brownish with a white or yellow belly in adults, which darkens in color under the tail. Encircling the lower half of the eye is a row of scales, which is separate from the upper lip scales. Among all southeastern U.S. snakes, only the green water snake has this feature. Juveniles have typically, about 50 dark crossbars on the dorsum and on the sides, which fade gradually with age.

N. floridana is found in Alabama, Florida, Georgia, and South Carolina. In southern South Carolina it is commonly found in open, marshy wetland areas. It is rarely found in rivers or streams. It prefers choked vegetation and calm waters such as swamps... Wikipedia →
