A rough-skinned newt underwater A rough-skinned newt at Brice Creek in Oregon. Throughout much of the newt's range, the common garter snake (Thamnophis sirtalis) has been observed to exhibit resistance to the tetrodotoxin produced in the newt's skin. While in principle the toxin binds to a tube-shaped protein that acts as a sodium channel in ...
Common garter snakes are resistant to naturally-occurring poisons in their prey, such as that of the American toad and rough-skinned newt, the latter of which can kill a human if ingested.

Garter snakes can bite or strike humans if they feel threatened. Small garter snakes eat prey such as slugs and earthworms, but larger garter snakes eat birds, fish, amphibians and rodents. The ...
Their populations in northern Oregon are more toxic than those from California and Washington. Those on Vancouver Island, in British Columbia, possess little or no tetrodotoxin. [8] Taricha newts can be lethal to humans if ingested, and at least one human fatality occurred in Oregon from eating a rough-skinned newt.
