Viviparous lizards are a unique group of reptiles that give birth to live young instead of laying eggs. This reproductive strategy allows them to thrive in colder climates where egg development might be challenging. They are found in various habitats, including grasslands and forests, and are known for their adaptability. These lizards belong to the family Lacertidae and are primarily distributed across Europe and parts of Asia. The most well-known species is the Viviparous Lizard or Zootoca vivipara, which can be identified by its slender body and ability to change color. Their diet mainly consists of insects and small invertebrates.
