Outside Virginia, the record length is 52 inches. In Virginia, maximum known SVL is 940 mm (37.0 inches) and maximum total length Species is 6 inches at birth and grows to about 4 feet. Juveniles are similar to adults but have much redder blotches. The belly is whitish with squarish black blotches giving a checkerboard effect.
