Asian common toad

A distinction between frogs and toads is not made in taxonomy, but is common in popular culture, in which toads are associated with drier skin and more terrestrial habitats than animals commonly called frogs.In taxonomy, toads are found in the families Bufonidae, Bombinatoridae, Discoglossidae, Pelobatidae, Rhinophrynidae, Scaphiopodidae, and Microhylidae.A group of toads is called a knot.

The bumps on a toad's skin help the animal to blend into its environment visually by breaking up its outline.Although the parotoid glands are sometimes referred to as "warts", they are present on healthy specimens and are not a result of infection.
