Phrynocephalus mystaceus, also known as the secret toadhead agama [2] and toad-headed agama, [1] is a species of agamid lizard. It is found in southern Russia, Kazakhstan, and northwestern China (Xinjiang) and southward to northern Iran, Afghanistan, Turkmenistan, Tajikistan, Kyrgyzstan, and Uzbekistan. [1] [2] The most exciting feature of the toad-headed agamas is their defense mechanism. When threatened, they flatten their bodies and open their mouths wide, such that their bright-colored flaps open. This, along with continuous hissing, scares whatever predator they encounter.
