She has eyelids and can blink.
Her jaw cannot unhinge, nor does she have venom glands.
She has a fleshy tongue rather than the long, forked tongue snakes have.
She cannot constrict prey.
She has ear holes.
Like other lizards, if you grab her by the tail, it will break off! (This is where she gets her name from, people used to think they were made of glass and were breakable as such!)

Damn it... if it wasn't for the last one, I would also be a lizard!
