|Hochstetter's Frog (Leiopelma hochstetteri)|
Archaeobatrachia is a suborder of Anura. It has various primitive frogs and toads. As the name literally suggests, these are the most primitive frogs. Many of the species (28 in total) show certain body features which are not in other frogs and toads. They are mostly found in Eurasia, New Zealand, the Philippines and Borneo.
In addition, the family Ascaphidae is found in the Pacific Northwest of the United States. They are only represented by two species.
