Nerodia clarkii taeniata, commonly known as the Atlantic salt marsh snake, is a species of semiaquatic, nonvenomous, colubrid snake found only in the Atlantic coast salt marshes of Volusia and Brevard County, Florida. It is currently listed as a Threatened Species by the US Fish and Wildlife Service.
Description
The Atlantic Salt Marsh Snake is a slender, heavily keeled water snake with a pattern of stripes that are variously broken into blotches. The dorsal ground color is pale olive, patterned with a pair of dark brown stripes running down the back and enclosing a pale mid-dorsal stripe. These dark stripes usually become fragmented posteriorly into a series of elongated blotches. There is also a row of dark blotches along the lower side of the body, which may merge to form stripes in the neck region.
