Common Name: Secret Toad-headed Agama
This is definitely one of the weirdest looking lizards that have been featured on the site. At first, it looks pretty normal..And then it opens its mouth!
Scientifically described as Phrynocephalus mystaceus, this agamid lizard can be found in Iran, North Afghanistan, Eastern Caucasus, Kazakhstan, Uzbekistan and possibly in south of Astrakhan Oblast. With the tail straightened, adults can reach a length of up to 9,44 inches (24 cm).
Commonly known as the secret toadhead agama, the species is best known for its secret red oral display frill that unfolds when the creature is frightened by predators(hence the name). The creature will also hiss and show its teeth to deter its enemies. Well, I would probably be disgusted and leave it alone but I guess it works the same :)
