Since I got my anole 2 months ago, he's gone through some physical changes. He grew his dorsal crest, and he puffs out his neck and chest when he displays that. The obvious motive is to look bigger.

However, he recently started doing something with his eyes which I have not read about. On occasion, I see him with his eyes bulged out. They'll be almost the size of peas, and very noticeably extended from his skull. The first time I saw it, I got real nervous, I thought maybe he had some kind of fluid build up, and I was afraid of them bursting. However, as soon as I looked in closely to get a better look, and he noticed me; they immediately shrunk back down, and he was looking at me like normal.

Is this eye thing significant? Is it just another stunt to look bigger?
