Also known as Western Diamond-backed Rattlesnake, Texas Rattlesnake, Coon Tail Rattler
Western diamondback rattlesnakes are heavy-bodied pit vipers recognized by their dark diamond markings and black-and-white banded tails. They rely on specialized heat-sensing pit organs between their nostrils and eyes to hunt warm-blooded prey in darkness. When cornered, they coil into a defensive posture, raise their heads, and shake their keratin rattles to produce an unmistakable buzzing warning.
