The amphibian order Salientia or Anura consists of the frogs and toads. There is no scientific distinction between "frogs" and "toads." Frogs are typically smooth-skinned, have long hind limbs for leaping, and live in water. Toads have warty, drier skin, with shorter hind limbs for hopping, and live on land. Sites in this category deal with the biology of frogs and toads as they exist in nature, including topics such as description, taxonomy, life cycle, and conservation.
