Gymnophthalminae

Gymnophthalminae is a subfamily of lizards within the family Gymnophthalmidae. These are generally small to medium-sized, slender-bodied lizards found in Central and South America. A defining characteristic of many species within this subfamily is the presence of transparent eyelids, or spectacles, which allow them to see with their eyes closed, similar to snakes. This feature is the origin of their subfamily name, which derives from the Greek words "gymnos" meaning naked and "ophthalmos" meaning eye.

Gymnophthalmines are primarily terrestrial or semi-arboreal and inhabit a variety of environments, from rainforests to savannas. Their diet typically consists of small invertebrates such as insects and spiders, though some may also consume small vertebrates or plant matter. Many species are diurnal, meaning they are active during the day. Reproduction in Gymnophthalminae is typically oviparous, with females laying eggs. While some species are well-studied, the diversity within this subfamily means that life history traits can vary significantly between different genera and species. Conservation statuses for many gymnophthalmine species are not yet well-assessed due to ongoing taxonomic research and limited surveys in their often remote habitats.
