More commonly known as the toad-headed agama, Phrynocephalus Arabicus is a lizard from the Agamidae family or the chisel-teeth lizards. They are primarily characterized by their compressed, fused teeth that are attached to their upper jaw. They are weird because most pictures of lizards commonly have loosely attached teeth. These lizards also have the excellent ability to change their body color that is why they are dubbed as the chameleons of the Old World. They also have a wide, strong, and flattened body that is covered in rough skin, as well as a tail that is flat though rounded at the base to one another by curling and uncurling their tails, vibrate their bodies to bury themselves quickly in sand and will frighten away predators with a set of bizarre-looking, colorful mouth flaps, seen here.
