Nerodia clarkii, commonly known as the salt marsh snake, is a species of semiaquatic, nonvenomous, colubrid snake found in the southeastern United States, in the brackish salt marshes along the Gulf of Mexico from Florida to Texas, with a population in northern Cuba.
Populations in Florida from Tampa Bay south to Miami and northward along the Atlantic coast to the vicinity of Cape Canaveral are referred to as the mangrove salt marsh snake (N. c. compressicauda). This subspecies exhibits many colors and patterns and can be gray, green, or tan with darker banding or may even be solid reddish orange or straw yellow.
