Chameleon eyes. They're cool. They swivel independently, they give some indication of the animal's health (i.e. whether they're sunken or not), and we've all witnessed our animals close an eye, do some very peculiar looking motions behind that lid, then open it up again.
I'm curious about how this works, most particularly the apparent "pulling in" of the eye, such that the turret is momentarily not bulging and things are moving around back there. What is responsible for a healthily rounded turret? Does it cover a large, spherical eyeball which can itself be retracted somehow into the socket? Are muscles (tense or lax at various times) responsible? Do blood vessels engorge to inflate the turret? Is it somehow water (analogous to turgor pressure)? - I would appreciate input from those In The Know.
