Hello everyone. I was hoping that you guys might be willing to take a minute and review this list. It is a list that I have acquired of the venomous snakes of the united states. I was hoping you guys would be willing to provide me some insight as to whether this list is complete or not.

I appreciate your time everyone.

I'm just curious, but why are the massaugas and the pygmies sistrurus instead of crotalus? And what is the difference between micriodes and micrurus in the elapids?

Ian

In addition to all the cool rear fanged snakes, and of course the two lizards if you would like to include them, you have missed whatever the latest release is in Florida

There are various morphological differences between Crotalus and Sistrurus including, but not limited to differences in skull and jawbone morphology, and the presence of large platelike scales on Sistrurus (as opposed to the many, small scales on Crotalus sp.). Additionally, mtDNA differences show that Sistrurus and Crotalus do indeed belong in different genera, at least for the time being. Cambell and Lamar (2004) did move Sistrurus ravus (Mexican Pygmy) to Crotalus ravus based on the similarities in jawbone and skull structure, and I believe mtDNA evidence as well (I think, lol, don't have the sources directly in front of me ).

As for the coralsnakes, the short answer is again that there are various morphological and genetic differences in the two taxa. There is also a third genus of new world coral snakes (though they don't range into N. America) called Leptomicrurus. Micruroides is a monotypic genera, containing only one species.

While their venom might not be enough to harm you: Western, Eastern, and Southern Hognose.

I guess if we're talking venomous and not snakes with fangs, perhaps gartersnakes!

Such a debatable list you have started!
