|Giant horned lizard|
The giant horned lizard (Phrynosoma asio) is a species of phrynosomatid lizard which is endemic to the Pacific coast of southern Mexico. It is the largest horned lizard and is also the most slender (it has a typical lizard-like appearance). Like all lizards, the giant horned lizard is cold-blooded. It is able to survive in the desert. The spines on its back and sides are made from modified scales, whereas the horns on its head are true horns (i.e., they have a bony core).
