Secret Toadhead Agama

Phrynocephalus mystaceus, also known as the secret toadhead agama and toad-headed agama, 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.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.
