The Ceratophryidae, also known as common horned frogs, are 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.
3 extant genera, see text.
Despite the common name, not all species in the family 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).
Placement of this clade has varied considerably over time, having been a subfamily within the Leptodactylidae for a long while. Later on, it has been raised to family level, either broadly defined, including the Telmatobiidae and Batrachylidae (as subfamilies Telmatobiinae and Batrachylinae, respectively), or as now is commonly accepted, as a smaller family with three genera.
