When people picture a rattlesnake, they generally think of the diamondback and not the shy massasauga rattlesnake. This snake’s name means “big river mouth” in Chippewa, and is named for the type of areas it is commonly found in, namely bogs and marshes. Although the massasauga rattlesnake was once plentiful in numbers, human interference has caused its numbers to dwindle, and it is now being considered for addition on the endangered species list.
