Usually 3–5 ft. (max. ~7 ft.)


Body color is tan, brown, or grayish; back is marked with a row of obvious dark diamonds outlined in cream. Distinct, dark bands, outlined in white, run from the corner of each eye to the corners of the jaw. Tail is tipped with a large rattle. Scales have obvious lengthwise ridges (keels). This snake gives birth to live young (does not lay eggs).


Found throughout Florida in flatwoods, sandhills, hammocks, and other dry forested habitats but generally avoids interiors of marshes and swamps. In urbanized areas, it may be found on golf courses and wooded lots.


Ground-dwelling birds, mice, rats, squirrels, gophers, small rabbits
