Atlantic Salt Marsh snake (Nerodia clarkii taeniata)
Where Listed: WHEREVER FOUND
The Atlantic salt marsh snake is a slender, heavily keeled water snake about 2 feet in total length, 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 elongate blotches. There is also a row of dark blotches along the lower sides of the body, which merge to form stripes in the neck region. The ventral surface is black with a median series of yellowish spots. This snake feeds on small fish in shallow water. It is most active at night, during periods of low tide.

» Life History
The Atlantic salt marsh snake inhabits coastal salt marshes and mangrove swamps. Specifically, it occurs along shallow tidal creeks and pools, in a saline environment ranging from brackish to full strength. It is often associated with fiddler crab burrows.
Movement / Home Range
Although historically reported from coastal areas of Volusia, Brevard, and Indian River counties, Florida, it now appears to be restricted to a limited coastal strip in Volusia County. Its population level is currently unknown.
Little is known about the life history of this snake, but it is probably similar to the Gulf salt marsh snake. Females of the Gulf Coast race produce from 2 to 14 live young, usually in mid-summer.
