Additionally, we provide some of the first links between secreted venom proteins, the genes that encode them, and their evolutionary origins in a rear-fanged colubrid snake, together with new genomic insight into the coevolutionary arms race between garter snakes and highly toxic newt prey that led to toxin resistance in garter snakes.

Most Garter snakes are not aggressive in nature but, if disturbed, they often coil and strike, or they may discharge a malodorous and musky-scented secretion from a special gland near the cloaca to avert harm. Only clinically essential procedures should be, performed in these patients and always at sites that allow, some direct pressure, as needed to help control bleeding, There are few well-documented data about bites, by several NFFC species that have been suspected.

In addition, their highly-effective defense mechanisms also play a hand in the degree to which the garter snakes flourish. These reptiles comprise the genus Thamnophis, and are endemic to Northern America.
