Report Eastern Diamond-backed Rattlesnake Observations

Eastern Diamond-backed Rattlesnakes are large, heavy-bodied rattlesnakes that are native to the southeastern United States.  They are characterized by dark-brown to black diamond-shaped markings that run down the back. The dorsal background color ranges from platinum silver to nearly black but is typically a shade of brown.  A dark brown to black stripe, bordered by two white or cream colored stripes, runs from the eye to the corner of the mouth.  Juveniles resemble adults in color and pattern.
