Photographer's Note

Lizards are a very large and widespread group of squamate reptiles, with nearly 3,800 species.
Lizards range greatly in size from the miniature Dwarf Gecko to the massive Komodo Dragon. Most lizards are completely harmless to humans even if bitten by one, while a few lizards contain venom such as the Mexican Beaded lizard and the Gila Monster.
Most lizards rely heavily on body language, using specific postures, gestures and movements to define territory, resolve disputes, and entice mates. Some species of lizard also utilize bright colors, such as the iridescent patches on the belly of Sceloporus. These colors would be highly visible to predators, so are often hidden on the underside or between scales and only revealed when necessary.
