Lacerta vivipara, commonly known as the common lizard or viviparous lizard, is a small reptile found across Europe and parts of Asia. This species is notable for its ability to give birth to live young, a rare trait among lizards. Typically, they inhabit grasslands, forests, and rocky areas, preferring warm environments. The common lizard has a slender body, usually measuring between 15 to 25 centimeters in length. Its coloration varies, often featuring shades of brown, green, or gray, with dark stripes or spots. Lacerta vivipara is an important part of its ecosystem, serving as both predator and prey.
