Agamidae:

A number of agamids developed highly specialized adaptions like the genus Draco which is the only lizard genus that has evolved a gliding flight made possible by elongate ribs which support a flight skin. Chlamydosaurus has large frills and several genera show enlarged scales all over the body (e.g. Moloch) or all over the tail (like Uromastyx). In contrast to most lacertids, many agamids don't autotomize their tails. However, members of the genera Agama, Physignathus, and Laudakia have evolved intervertebral autotomy ans opposed to the commonly found intravertrebral autotomy found in other lizard families.
