The Caatinga horned frog, scientifically 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 inhabits areas with seasonal rainfall, where it can be found in leaf litter and near temporary ponds. These frogs are known for their ambush predation strategy, often remaining still and waiting for prey to come close. They primarily feed on insects and small vertebrates. The Caatinga horned frog plays a vital role in its ecosystem by helping control insect populations and serving as prey for larger animals.
