Toads are a group of frogs in the family Bufonidae. The family is extremely large, consisting of over 500 species in over 40 genera. Toads are native to the Americas, Europe, Asia, and Africa, but absent in Australia and Antarctica. Toads are also very variable in terms of shape, colour, and general design.
Toads are neobatrachians, or advanced frogs, and within the Neobatrachia, they are part of the superfamily Hyloidea, which also includes tree frogs and poison-dart frogs. Bufonidae, the true toads, is the second-largest family within the Hyloidea, after Hylidae, the New World tree frogs. Within the Bufonidae, the toads are grouped into two subfamilies: Bufoninae (Bufo and its relatives) and Pedostibinae (Pedostibes and its relatives).
