The caatinga horned frog, also known as Ceratophrys joazeirensis, is a species of frog native to the Caatinga biome in northeastern Brazil. This frog is characterized by its distinctive horn-like projections above its eyes and a robust body. It typically has a green or brown coloration that helps it blend into its arid surroundings. These frogs are primarily terrestrial and are known for their ambush predation strategy, often waiting for prey to come close before striking. They feed on a variety of small animals, including insects and other frogs. The caatinga horned frog plays an important role in its ecosystem by helping to control insect populations.
