Do Frogs Have Warts?
No. The bumps and the lumps you see on the skin of some amphibians (usually toads) are glands filled with foul-tasting poison, which protects them from hungry predators, says David Mizejewski, a naturalist at the National Wildlife Federation, in Reston, Virginia. By the way, frogs are hopping mad that they’ve been unfairly blamed for causing warts. Warts actually come from viruses and can be transferred only from human to human. Toadally gross.
