About half a minute prior to striking, a very large Western Gopher Snake readies itself to take down a packrat. The largest species of snake in Arizona, Gophers can reach over 7 feet in length; pure constrictors with sharp, tiny teeth but no fangs, they live off rodents, birds, other snakes and whatever they can hunt. Taken inside an excavated room at the Rattlesnake Point Historical Site in Lyman Lake State Park, an excavated ancestral Puebloan village, this photo was pure serendipity.
