By Ethan Anderson| Reviewed by Olivia Bennett, Standards & Fact-Checking Lead| Updated July 27, 2026|2 min read| Fact-checked

Skinks are lizards in the family Scincidae, one of the largest and most diverse families of lizards. They typically have smooth scales, elongated bodies, and relatively short limbs, though some species are limb-reduced or limbless. Skinks occur in many habitats worldwide, with especially high diversity in Australia, Southeast Asia, and parts of North America.

Taxonomy and diversity

Skinks belong to the family Scincidae within the order Squamata, which also includes the Gecko and Komodo Dragon. They are among the most species-rich lizard families, with well over 1,400 to 1,500 described species depending on the source date.

Physical characteristics

Skinks are generally small to medium-sized lizards with smooth scales, elongated bodies, and reduced limbs. Some species are limbless or nearly limbless, while others have well-developed legs. Their streamlined bodies and glossy scales are distinctive.

Distribution and habitat

Skinks occur across most of the world, with notable diversity in Australia, New Guinea, Southeast Asia, and parts of North America. They live in a wide range of habitats, including forests, deserts, grasslands, mountains, and subterranean or leaf-litter environments. In Canada, several species such as the five-lined skink are found, with that species being the country's only native lizard in Ontario and a species of conservation concern.

Ecology and behaviour

Many skinks are secretive, ground-dwelling, or burrowing reptiles. Their diets vary by species and may include insects, other small invertebrates, plant material, or small vertebrates. Some species are nearly legless and resemble snakes in form and movement, much like the Garter Snake.

Key facts

  • Skinks are lizards in the family Scincidae, with more than 1,500 described species across about 100 genera.
  • They are found worldwide except in arctic and subarctic regions, with high diversity in Southeast Asia, Australia, and temperate North America.
  • Many skinks have smooth, glossy scales, small limbs, and a streamlined body shape; some are nearly legless.
  • Skinks occupy a wide range of habitats including forests, deserts, mountains, grasslands, and leaf litter.

Canadian context

Several skink species occur in Canada, including the five-lined skink, which is the country’s only native lizard in Ontario and is a species of conservation concern there.[6]
