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. 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 Lepidobatra

Chacophrys pierottii, the Chaco horned frog or lesser Chini frog, is a species of frog in the family Ceratophryidae. It is monotypic within the genus Chacophrys. It is found in the Chaco of northern Argentina, eastern Bolivia, and western Paraguay. Its natural habitats are dry shrubland and gallery forest.
