Tail curve

A male Yarkand toad-headed agama (Phrynocephalus axillaris) is sending signal by it's curving tail. Tail curve, tail lash and tail wave are main form of the lizards' communication. Our research group have been working on this lizards for more than five years. Now we believe the tail signal has correlation with courtship and territorial defence.
