Lepidosauria is a group of reptiles that includes modern lizards and snakes, as well as their close relatives, the tuataras. These creatures are characterized by their scaly skin and ability to shed their skin in layers. They are found in various habitats around the world, from deserts to forests, and have adapted to a wide range of environments. One of the most interesting features of Lepidosauria is their diverse methods of locomotion. Some, like geckos, can climb vertical surfaces thanks to their specialized toe pads, while others, like snakes, move by slithering. This adaptability has allowed them to thrive in many ecosystems.
