Rough-skinned newts produce a strong toxin called TTX as a defense mechanism against predators. Garter snakes can
tolerate a very limited amount of the toxin. However, several populations of garter snakes have recently shown an
increased tolerance for TTX. The different populations of snakes have independently acquired a gene variation that
allows them to better block the effects of the toxin.
