Chameleon Research

I am researching Chameleons for my book. I thought erroneously that this rare and beautiful but weirdly ugly animal changed color based on its background or surroundings...not so!

This photo is from a FANTASTIC PICTURE BOOK called:
"Chameleon, Chameleon" by JOY COWLEY
with PHOTOGRAPHS by NIC BISHOP (Scholastic)
I am also using another picture book called: CHAMELEONS
by Sophie Lockwood (The Child's World)
There are different varieties of chameleons and they change color based on mood -- basically to show aggression or affection or attraction. They have lightning fast tongues and are listed as "threatened" in Kenya. But I did see one when I lived there though, so I decided to put it in my book.
