}}Nerodia clarkii clarkii, the Gulf salt marsh snake, is a subspecies of N. clarkii that is indigenous to the southeastern United States. It is a nonvenomous, colubrid snake that inhabits coastal salt marshes and brackish estuaries along the coast of the Gulf of Mexico from Florida to Texas.[1][2] DescriptionThe Gulf salt marsh snake is a moderately stout aquatic snake.[1] Adult specimens attain an average total length (including tail) of {{convert|38|to|51|cm|in|abbr=on}}, with the record maximum total length at {{convert|91.4|cm|in|abbr=on}}.[2] The color pattern in this subspecies is variable, but adults tend to have a dorsum that ranges from dark gray to reddish-brown with four yellowish longitudinal stripes down the body, two on each side. The belly is dark gray to reddish-brown with one to three rows of pale spots.[1][2] ReproductionThe Gulf salt marsh snake reaches sexual maturity at three years. Females give birth to 2-44 live young that range from {{convert|17.7|to|22.8|cm|in}} in total length. Their typical lifespan is up to 20 years.[1][2] DietN. c. clarkii is primarily nocturnal, preying upon small fish, crabs, shrimp, and other invertebrates that become trapped in tidal pools during low tide.[1][2]References1. ^1 2 3 4 {{cite book |title=The Reptiles and Amphibians of Alabama |last=Mount |first=Robert H. |year=1975 |publisher=Auburn Printing Company |location=Auburn, Alabama |oclc=1958638 |pages=215–216}} 2. ^1 2 3 4 {{cite web |url=http://www.flmnh.ufl.edu/herpetology/fl-guide/Nerodiacclarkii.htm |title=Gulf Salt Marsh Snake |work=Florida Museum of Natural History |publisher=University of Florida |accessdate=October 1, 2012}} Further reading
