Crotaphytid lizards or more commonly known as Collared lizards are found in North America only (American southwest and northern Mexico). They typically prey on other lizards and other vertebrates for their sustenance. There are 12 species found in two genera (below).

- Femoral pores present.
- Interparietal scale small (distinctly smaller than ear opening) unlike Iguanidae.
