Eastern Massasauga Rattlesnake
(Sistrurus catenatus) The smallest of three venomous snakes found in NY State — the other two being the copperhead and timber rattler. Also known as the “swamp rattler” the massasauga averages just over two feet in length and makes his home in Cicero Swamp. Venomous snakes are distinguished by their broad head and vertical pupils. The rattle is also a … dead giveaway.
