This list of Anuran families shows all extant families of Anura. Anura is an order of animals in the class Amphibia that includes frogs and toads. More than 5,000 species are described in the order. The living anurans are typically divided into three suborders: Archaeobatrachia, Mesobatrachia, and Neobatrachia.
There are 107 classes of animals in 33 phyla in this list. However, different sources give different numbers of classes and phyla. For example, Protura, Diplura, and Collembola are often considered to be the three orders in the class Entognatha. This list should by no means be considered complete and authoritative and should be used carefully.
