What is the binomial nomenclature of snake?

Binomial means two names. Which means that snakes are generally labeled by Genus before Species, and in some instances, a Subspecies. For instance, if you're trying to generalize the garter snake you just found, you would label it as: Thamnophis sp. With Thamnophis being the genus and sp. being the species. Same with rattlers (Crotalus), Pythons (Python), etc... But if you are trying to pinpoint a certain snake to the species, you would use the format of: Genus sp. For instance, using common herpetofauna, the common garter snake would be Thamnophis sirtalis with sirtalis being the species. But if you were trying to say it was a two banded garter, it would be Thamnophis hammondii. Western Diamondback: Crotalus atrox, Timber rattlesnake: Crotalus Horridus, Python regius: Ball or Royal Python.

For SNAKE in general, there is no BInomial nomenclature. Serpentes is the suborder, with Squamata being the Order.
