The common lizard, scientifically known as Zootoca vivipara, is a small reptile found across Europe and parts of Asia. It typically measures between 15 to 25 centimeters in length and has a slender body with a long tail. Its coloration varies, often featuring shades of brown, green, or gray, which helps it blend into its surroundings. This lizard is known for its adaptability to different habitats, including grasslands, forests, and rocky areas. It is primarily active during the day, basking in the sun to regulate its body temperature. The common lizard is also unique for its ability to give birth to live young in some populations, a trait known as viviparity.
