The dusky pigmy rattlesnake is a small species found throughout the marshy lands of the United States
southeast. This species was so named because of the dusky or silty appearance that many individuals have. The
background color is most often a black gray or brown.
Description:
The body is adorned with many pattern features. The most prominent of the features is a reddish or orange
dorsal strip that runs down the back. This stripe may be absent in some populations which tend to be
anerythristic or melanistic. The stripe is interrupted by a series of black or brown dorsal blotches usually
bordered with some white. Two rows of blotches run laterally on each side with the middle row of blotches
typically lighter in color. The belly is white but usually mottled with dark color and has blotches on the
edges that can be seen from the side. The tail ends in a miniscule rattle.
