Skinks are lizards belonging to the family Scincidae. Together with several other lizard families, including Lacertidae (the "true" or wall lizards), they comprise the superfamily or infraorder Scincomorpha. With about 1200 described species, the Scincidae are the second most diverse family of lizards, exceeded only by the Gekkonidae (geckos).
