What is a "lizard"?

Lizards are a diverse group of reptiles characterized by their scaly skin, elongated bodies, and four legs. They come in various sizes, shapes, and colors, and can be found in different habitats around the world, from deserts and forests to tropical rainforests and grasslands. Lizards are known for their ability to climb, crawl, and sometimes run at impressive speeds. They have a wide range of diets, with some species being herbivorous, while others are carnivorous or omnivorous. Lizards play important roles in ecosystems as both predators and prey, contributing to the balance of their respective habitats. Some species of lizards, such as geckos, are also popular pets due to their unique characteristics and relatively low maintenance requirements.
