Ceratophryidae
Ceratophryidae, known as common horned frogs, is a family of frogs found in South America. It is a relatively small family with three extant genera and 12 species. However, fossils of the giant ''Beelzebufo'' from Cretaceous Madagascar suggest the taxon may have once ranged throughout the prehistoric supercontinent of Gondwana.
Despite the common name, not all species in the subfamily have the horn-like projections at the eyes. They have a relatively large head with big mouth, and they are ambush predators able to consume large prey, including lizards, other frogs, and small mammals. They inhabit arid areas and are seasonal breeders depositing many small eggs in aquatic habitats. Tadpoles are free-living and carnivorous (''Ceratophrys'' and ''Lepidobatrachus'') or grazers (''Chacophrys'').
Some species (especially from the genera ''Ceratophrys'' and ''Lepidobatrachus'') are popular in herpetoculture.
==Taxonomy==
Placement of this clade has varied considerably over time, having been a subfamily within Leptodactylidae for a long while. Later on, it has been raised to family level, either broadly defined, including Telmatobiidae and Batrachylidae (as subfamilies Telmatobiinae and Batrachylinae, respectively〔), or as now is commonly accepted, as a smaller family with three genera.〔〔〔
