## Summary

Nerodia clarkii, commonly known as the salt marsh snake or the saltmarsh watersnake, is a species of semi-aquatic, nonvenomous, colubrid snake found in the southeastern United States. Their range extends along the tidal salt marshes of the Gulf of Mexico and the Atlantic Coast from Texas to Florida, with an additional population in northern Cuba. The three subspecies of this snake are primarily distinguished by color pattern and geographic range.
Salt marsh snakes are the only U.S. snake species indigenous to saltwater habitats, being reported as common on coastal barrier islands without freshwater (Allen 1932).
