Ophisaurus, commonly known as glass lizards, are legless reptiles resembling snakes but distinguished by their movable eyelids and external ear openings. They inhabit grasslands and open woodlands across North America and Eurasia, feeding on insects and small invertebrates. Notably, they can shed their tail to escape predators, which then regenerates over time.

Ophisaurus, commonly known as glass lizards, are primarily found in the southeastern United States. They inhabit regions from North Carolina to Florida and westward to Texas. Some species of Ophisaurus are also found in parts of Europe and Asia, including the Mediterranean region and Southeast Asia.

Glass lizards typically inhabit dry, open areas such as grasslands, sandhills, and pine flatwoods. They are also found in dry, rocky hillsides and sometimes in scrubby areas or open forests. These environments are characterized by loose, sandy, or loamy soils which are conducive to burrowing.

Ophisaurus species are primarily terrestrial and are well-adapted to a life spent mostly underground or hidden under debris. They are carnivorous, feeding on a variety of invertebrates and small vertebrates. Their elongated, legless bodies enable them to move easily through their sandy or loose soil habitats, allowing them to escape predators and pursue prey efficiently.
