By browsing a PDF showing the amphibians and reptiles of Cuba, I found a picture of a beautiful anole:
Anolis equestris potior.
After doing some research, I was able to find very little info about it. It was described in 1975 by Schwartz and Thomas and lives only on Cayo Santa Maria (province Villa Clara)! It would take on the beautiful blue color during stress or “emotion,” just as some other species of anoles take on a dark phase.
