what is it?

The massasauga ( Sistrurus catenatus ) is a rattlesnake species found in midwestern North America from southern Ontario to northern Mexico, and parts of the United States in between. Three subspecies are currently recognized including the nominate subspecies described here. As with all rattlesnakes, it is a pit viper (and as with all pit vipers, it is venomous).
