I'm fascinated by lizards. 
They are definitely interesting! There are over 6000 species of lizards.
I wonder if they're broken down into sub-species.

I know a lot of them are green, or brown, but there are probably other colors as well.

Anatomy.
Anatomy Largest and smallest.
The adult length of species within the suborder ranges from a few centimeters for chameleons such as "Brookesia micra" and geckos such as "Sphaerodactylus ariasae" to nearly in the case of the largest living varanid lizard, the Komodo dragon. Most lizards are fairly small animals.
Anatomy Distinguishing features.
Lizards typically have rounded torsos, elevated heads on short necks, four limbs and long tails. Some are legless
Skink
Skinks are lizards belonging to the family Scincidae and the infraorder Scincomorpha. With more than 1,500 described species, the Scincidae are one of the most diverse families of lizards. Common skinks include many different kinds such as the slender skink, snake-eyed skink and the skinks of Plestiodon are among the common skinks.
Description.
Skinks look like true lizards, but most species have no pronounced neck, and their legs are relatively small; several genera (e.g., "Typhlosaurus") have no limbs at all
