COMMON WATERSNAKE
Nerodia sipedon, (Linnaeus, 1758)
  (nur-O'-dE-a sip-i'-don)

Recognition:
Northern Watersnakes are fairly dark-colored snakes and may be brown, tan or grayish. The coloration is much more vivid in young and wet specimens. Their back and sides have a series of square blotches that alternate and may merge to form bands. Their scales are keeled and the anal plate is divided. Adult females tend to be larger than adult males.

Confusing Species:
This species is often confused with the venomous Cottonmouth, but Cottonmouths have bands instead of blotches and their distribution is generally restricted to the extreme southeast Cherokee County.

Distribution:
Largly confined to the riparian areas of the state. However, it is commonly found in ponds, especially around the eastern half of the state.
Any populations that existed along the Arkansas River as it enters the state from Colorado may no longer be extant, as until recently, it has been dry.
