The western pigmy rattlesnake is Arkansas' smallest rattler. Adults grow to 2.5 feet. Another common name is the ground rattler.
Dark stripes run from behind the eyes to the corner of the mouth.
Dark bars down the center of the gray back are flanked by dark spots on the sides. A rusty orange stripe usually runs down the center of the back. Pigmy rattlers live in rock or brushy areas throughout Arkansas. Lizards and mice are their main prey. The buzzing of their tiny rattles is only audible a few feet away.
