Phrynosoma platyrhinos, commonly known as the flat-tailed horned lizard, is a species of lizard found primarily in the southwestern United States and northern Mexico. This lizard is characterized by its flattened body and distinctive horns on its head, which help it blend into its desert surroundings. It primarily feeds on ants and other small insects, using its specialized tongue to capture prey. The flat-tailed horned lizard prefers arid habitats, such as sandy deserts and scrublands, where it can easily camouflage itself among the rocks and vegetation. This species is known for its unique defense mechanism, which includes puffing up its body and displaying its horns to deter predators. Conservation efforts are important for maintaining its populations, as habitat loss poses a significant threat.
