“Examining the face Leopard geckos often look as though they are smiling. Although I know that is because of the way their face is constructed and the size of their mouth, I still like to think they’re happy! Especially my leopard geckos! The most prominent features on a leopard gecko’s face are his eyes. The eyes are very large, almost oversized, for his face. They are clear and clean and the eyelids well fitted to the eyes. The nostrils are also clear and clean, and when the gecko breathes, his breaths are easy and clear. The jaws are large, too, and fit together well, making the mouth close with a smooth line. The earholes can be open (if the gecko is relaxed and warm) or closed (if he’s cool or stressed).”
