Plestiodon is a genus of lizards commonly known as skinks, found primarily in North America and parts of Asia. These lizards are characterized by their smooth, shiny scales and elongated bodies, which often lack pronounced necks. They typically have short legs and a long tail, aiding in their burrowing and climbing abilities. Skinks in the Plestiodon genus are known for their diverse coloration and patterns, which can vary significantly between species. They are generally insectivorous, feeding on a diet of insects and other small invertebrates. Many species are also known for their ability to lose and regenerate their tails as a defense mechanism against predators.
