Widespread garter snake (Thamnophis sirtalis sirtalis) has advanced resistance on the defensive material tetrodotoxin in its amphibian prey.
This cycle of selection and reaction is known as coevolution.[225] An case in point could be the production of tetrodotoxin during the rough-skinned newt and also the evolution of tetrodotoxin resistance in its predator, the popular garter snake. In this particular predator-prey pair, an evolutionary arms race has created significant levels of toxin during the newt and correspondingly substantial levels of here toxin resistance while in the snake.[226] Cooperation
