Lizards are a diverse group of squamate reptiles that exhibit a wide range of forms, behaviors, and adaptations. They are found on every continent except Antarctica and occupy habitats ranging from deserts to rainforests. Some of the most well-known lizard families include the geckos (Gekkonidae), iguanas (Iguanidae), and chameleons (Chamaeleonidae), each with distinctive characteristics that set them apart. Geckos are renowned for their adhesive toe pads that allow them to climb smooth surfaces, iguanas are typically large and herbivorous with robust bodies and spiny crests, and chameleons are famous for their color-changing ability, prehensile tails, and independently mobile eyes. Together, these families showcase the incredible adaptability and evolutionary success of lizards within the Squamata order.
