The Western Massasauga or Sistrurus catenatus terminus is a light grey snake with 1.5 to 2.5-foot lengths that is observable with its white or cream features and scattered black markings. Similar to species like the Timber Rattlesnake, these types have diagonal cheek stripes going down and backward near the jaw. They like using their rattling tails to signal for noise and disruption and are hungry for frogs, lizards, and rodents.
