Desert Horned Lizard (Phrynosoma platyrhinos)
The Desert Horned Lizard, also known as the horned toad, is renowned for its impressive horns and flattened body. Found across the southwestern United States, it uses its cryptic coloration to blend into sandy and rocky environments. This lizard primarily feeds on ants and has a fascinating defense mechanism: it can squirt blood from its eyes to deter predators. Its unique appearance and behaviors make it a standout in desert ecosystems.
