Phrynosoma is a genus of lizards commonly known as horned lizards, found primarily in North America. They are characterized by their flattened bodies, spiny scales, and distinctive horns or projections on their heads. These adaptations help them blend into their desert and arid environments, providing camouflage against predators. Horned lizards primarily feed on ants and other small insects. They have a unique defense mechanism: when threatened, some species can squirt blood from their eyes to deter predators. This fascinating behavior, along with their unique appearance, makes Phrynosoma a subject of interest for both researchers and reptile enthusiasts.
