Lizards are fascinating reptiles that belong to the order Squamata. They come in various shapes, sizes, and colors, with over 6,000 species found around the world. Most lizards have long bodies, four legs, and a tail, which they can sometimes shed to escape predators. They are cold-blooded, meaning their body temperature depends on their environment, and they often bask in the sun to warm up. These creatures are known for their unique abilities, such as climbing walls and changing colors. Some lizards, like the chameleon, can blend into their surroundings for protection. They primarily eat insects and plants, making them important for maintaining ecological balance.
