'''''Phrynocephalus mystaceus''''', also known as the '''secret toadhead agama'''<ref name=RDB/> and '''toad-headed agama''',<ref name="iucn status 19 November 2021" /> 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]].<ref name="iucn status 19 November 2021" /><ref name=RDB/>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.<ref>Whiting, M. J., Noble, D. W. A., & Qi, Y. (2022, May 30). A potential deimatic display revealed in a lizard.
