What is the name for a slow-moving lizard that can change the color of its skin?

They are fascinating to watch.

may be another picture to represent?

Lil, you too my dear

got cut off, anyway they had a black thread around their neck attached to a safety pin. They would turn the color of my shirt ! My sister & I loved that.

Does anybody remember going to the circus in the 50's and they sold Chameleons for a dime or a quarter

I’ve known many chameleons; all of them human!

they used to have a picture to represent the animal when said animal was the correct answer. People complained that that made the question too easy, if you're that curious about what a chameleon looks like, Google it.

Doesn't look like any chameleon I've ever seen.
