All toads are frogs, but not all frogs are toads. While most frogs have moist, smooth skin and long legs for leaping, typical toads have dry, warty skin and short legs for hopping.

Despite common belief, touching toads does not result in warts; only viruses cause warts. When toads are handled with any pressure, though, toxins may ooze out from their skin as a defense mechanism. This liquid sometimes causes mild irritation, especially if you rub your eyes or mouth after holding a toad. For this reason, either leave toads alone or just be sure to wash your hands after handling them.
