Common horned frogs

The Ceratophryidae, also known as common horned frogs, are a family of frogs found in South America. It is a relatively small family with only 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.
