What is the only animal that is never bothered by the amphibians slimy skin?

The only animal that is never bothered by the slimy skin of amphibians is the garter snake. This snake has developed a tolerance to the toxins found in the skin of many amphibians, allowing it to prey on them without adverse effects. Garter snakes often consume frogs and salamanders, making them one of the few predators that can handle the slippery, toxic skin of these animals.
