Description
Salt marsh snakes grow to a total length of 15 inches (38 cm) to 30 inches (76 cm), and are highly variable in pattern and coloration. Populations of the Gulf salt marsh snake (N. c. clarkii) from the vicinity of Corpus Christi, Texas, to the Gulf Hammock region of Florida are gray, tan or yellow with four brown to black longitudinal stripes.
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.
A third subspecies, the Atlantic salt marsh snake (N. c. taeniata), is restricted to a small stretch of coastline in Volusia and Indian River Counties, Florida. This race is smaller than the other two and has a color pattern of four dark stripes on the neck which are replaced by a series of dark blotches or bands on the posterior portion of the snake's body. It is currently listed as a Threatened Species by the US Fish and Wildlife Service.

Famous quotes containing the word description:
“To give an accurate description of what has never occurred is not merely the proper occupation of the historian, but the inalienable privilege of any man of parts and culture.”
—Oscar Wilde (1854–1900)
“As they are not seen on their way down the streams, it is thought by fishermen that they never return, but waste away and die, clinging to rocks and stumps of trees for an indefinite period; a tragic feature in the scenery of the river bottoms worthy to be remembered with Shakespeare’s description of the sea-floor.”
—Henry David Thoreau (1817–1862)
“Once a child has demonstrated his capacity for independent functioning in any area, his lapses into dependent behavior, even though temporary, make the mother feel that she is being taken advantage of....What only yesterday was a description of the child’s stage in life has become an indictment, a judgment.”
—Elaine Heffner (20th century)
