Tropidoscincus

Skinks are lizards belonging to the family Scincidae, a family in the infraorder Scincomorpha. With more than 1,500 described species across 100 different taxonomic genera, the family Scincidae is one of the most diverse families of lizards. Skinks are characterized by their smaller legs in comparison to typical lizards and are found in different habitats except arctic and subarctic regions.

Acontias is a genus of limbless skinks, the lance skinks, in the African subfamily Acontinae. Most are small animals, but the largest member of the genus is Acontias plumbeus at approximately 40 cm (16 in) snout-vent length. All members of this genus are live-bearing sandswimmers, with fused eyelids. A recent review moved species that were formerly placed in the genera Typhlosaurus, Acontophiops, and Microacontias into this genus, as together these form a single branch in the tree of life. This new concept of Acontias is a sister lineage to Typhlosaurus, and these two genera are the only genera within the subfamily Acontinae.

Brachymeles is a genus of skinks. The majority of the species within the genus are endemic to certain island ecosystems in the Philippines. In 2018, the Zoological Society of London through its EDGE of Existence Program listed the Cebu small worm skink as the 80th most evolutionarily distinct and globally endangered reptile species in the world, making it the most endangered member of the genus Brachymeles.

Chalcides is a genus of skinks.

Cryptoblepharus is a genus of skinks, lizards in the family Scincidae. The genus contains at least 53 species.

Ctenotus is a genus of skinks, lizards in the family Scincidae. The genus is endemic to Australia. The genus Ctenotus belongs to a clade in the Sphenomorphus group which contains such genera as Anomalopus and the close relatives Eulamprus and Gnypetoscincus.

Lygosoma is a genus of lizards, commonly known as supple skinks or writhing skinks, which are members of the family Scincidae. Lygosoma is the type genus of the subfamily Lygosominae. The common name, writhing skinks, refers to the way these stubby-legged animals move, snake-like but more slowly and more awkwardly.

Mabuya is a genus of long-tailed skinks, lizards in the family Scincidae. The genus is restricted to species from various Caribbean islands. Out of 26 recognized species, six species are only found in Caribbean islands. Species in the genus Mabuya are primarily carnivorous, though many are omnivorous. The genus is viviparous, having a highly evolved placenta that resembles that of eutherian mammals. Formerly, many Old World species were placed here, as Mabuya was a kind of "wastebasket taxon". These Old World species are now placed in the genera Chioninia, Eutropis, and Trachylepis. Under the older classification, the New World species were referred to as "American mabuyas", and as of 2024 include the genera Alinea, Aspronema, Brasiliscincus, Capitellum, Copeoglossum, Maracaiba, Marisora, and Varzea.

Oligosoma is a genus of small to medium-sized skinks found only in New Zealand, Norfolk Island and Lord Howe Island. Oligosoma had previously been found to belong to the Eugongylus group of genera in the subfamily Lygosominae; the Australian genus Bassiana appears to be fairly closely related.

Scincella is a genus of lizards in the skink family, Scincidae, commonly referred to as ground skinks. The exact number of species in the genus is unclear, as taxonomic reclassification is ongoing, and sources vary widely. Scincella species primarily range throughout the temperate regions of the world and are typically small, fossorial lizards, which consume a wide variety of arthropods. They are a generalized insectivore with well developed chemosensory abilities.

The genus Sphenomorphus – vernacularly also known as the common skinks – currently serves as a "wastebin taxon" for numerous skinks. While most or all species presently placed here are probably rather close relatives, the genus as presently delimited is likely to be not monophyletic and is in need of review. Some species in this genus have been moved to Pinoyscincus.

Blue-tongued skinks comprise the Australasian genus Tiliqua, which contains some of the largest members of the skink family (Scincidae). They are commonly called blue-tongued lizards or simply blue-tongues or blueys in Australia or panana in Indonesia. As suggested by these common names, a prominent characteristic of the genus is a large blue tongue that can be bared as bluff-warning to potential enemies. The type of predator/threat that is near will determine the intensity of colour present in the tongue. The tongue can also deform itself and produce a thick mucus in order to catch prey. They are relatively shy in comparison with other lizards, and also significantly slower due to their shorter legs.

Trachylepis is a skink genus in the subfamily Mabuyinae found mainly in Africa. Its members were formerly included in the "wastebin taxon" Mabuya, and for some time in Euprepis. As defined today, Trachylepis contains the clade of Afro-Malagasy mabuyas. The genus also contains a species from the Brazilian island of Fernando de Noronha, T. atlantica, and may occur in mainland South America with Trachylepis tschudii and Trachylepis maculata, both poorly known and enigmatic. The ancestors of T. atlantica are believed to have rafted across the Atlantic from Africa during the last 9 million years.

Lygosominae is the largest subfamily of skinks in the family Scincidae. The subfamily can be divided into a number of genus groups. If the rarely used taxonomic rank of infrafamily is employed, the genus groups would be designated as such, but such a move would require a formal description according to the ICZN standards.

Eugongylinae is a subfamily of skinks within the family Scincidae. The genera in this subfamily were previously found to belong the Eugongylus group in the large subfamily Lygosominae.

Aubrey's whiptailed skink is a species of skink found in New Caledonia.

The southern whiptailed skink is a species of skink found in New Caledonia. Tropidoscincus variabilis is a medium-sized, long-limbed and long-tailed skink with strong ontogenetic change in coloration. They are more brightly colored as juveniles. They live primarily in forests and heathlands. Mature males and females are roughly the same size, but females have longer bodies, shorter heads and limbs, and a less brightly orange venter. Females lay 2–4 eggs in summer, and young hatch in late summer. More than one year of growth is required to attain maturity. They eat a large variety of invertebrates, particularly spiders and crickets. Juveniles eat more spiders, bugs and isopods than adults.

Phractura ansorgii, commonly known as the African whiptailed catfish, is a species of catfish in the genus Phractura. They live in the Niger and Oshun rivers in Africa. These fish eat algae. Their length ranges from 8 cm to 10 cm. It is named in honor of William John Ansorge.
