A toad is any of a number of species of amphibians in the order Anura characterized by dry, leathery skin, brown coloration, and wart-like parotoid glands. A distinction between frogs and toads, though common in popular culture, is not made in taxonomy, where toads are spread across families Bufonidae, Bombinatoridae, Discoglossidae, Pelobatidae, Rhinophrynidae, Scaphiopodidae, and Microhylidae. The characteristic features of toads are a result of convergent evolution in dry habitats.Toads cannot transmit warts to people through handling or skin contact. The bumps on a toad's skin help the animal blend into its environment visually by breaking up its outline. They are present on healthy specimens and are not a result of infection.
