Acontinae Lygosominae Scincinae (probably paraphyletic) For genera, see below.
Skinks are the most diverse group of lizards. They make up the family Scincidae which shares the superfamily or infraorder Scincomorpha with several other lizard families, including Lacertidae (the "true" or wall lizards). Scincidae is the largest of the lizard families with about 1,200 species.

Description
Skinks are generally omnivores and largely eat insects. They also eat spiders, earthworms, isopods, other lizards, and small rodents. Some species, particularly those favored as home pets, have a more varied diet and can be maintained on a regimen of roughly 60% vegetables/leaves/fruit and 40% meat and meat products.

Diet
Skinks are found in a variety of habitats worldwide. Some species are endangered.
Many species are good burrowers. There are more terrestrial or fossorial (burying) species than arboreal (tree-climbing) or aquatic species. Some are "sand swimmers", especially the desert species, such as the Mole skink in Florida. Most skinks are diurnal, so they are active during the day. They like to crawl out on rocks or logs to bask (soak up heat from the sun) during the day.

Gallery
Many large genera, Mabuya for example, are still insufficiently studied, and systematics is at times controversial, see e.g. the taxonomy of the Western Skink (Eumeces skiltonianus).
