(Western Mud Snake ) MDC Online. Accessed May 18, 2013〕 with the record total length being slightly over 80 inches (2 m).〔The University of Georgia. 2008.

The underside is red and black, and the red extends up the sides to form bars of reddish-pink. Their heavy bodies are cylindrical in cross section, and their short tails have a terminal spine. Their head scalation is distinctive in that they have only one internasal, no preocular, and one anterior temporal. The dorsal scales are smooth, and are arranged in 19 rows at midbody.
