My husband put a penny by this Toad so I could show how small this little guy was. Like salamanders, toads have poisonous skin. The "warts" on a toad contain the poison which is released if an animal tries to eat it. We found this toad along the trail at Big Ridge State Park. Contrary to the old wives' tale, toads and frogs cannot give a person warts (they are caused by a virus)!
