VENOMOUS SNAKES FOUND IN EACH STATE
Let me start by saying that I am not a herpetologist. This page is designed to list the venomous snakes of each state, but should in no way be considered an authoritative list. This page was compiled from information in the public domain, and has not been reviewed by a herpetologist.
I don't expect everyone to be able to identify all species of snakes found in their area, but I think it is important that they be able to recognize the venomous ones.
Please take the time to learn about the venomous snakes and other venomous animals of your own area, and teach your children and loved ones about them as well. In addition to the lists below, I have many links on my Venomous Links page that may assist in learning about the venomous snakes in your area.
