Squamata is a diverse order of reptiles that includes lizards and snakes. These creatures are characterized by their scaly skin and flexible jaws, which allow them to consume prey larger than their heads. With over 10,000 species, Squamata can be found in various habitats around the world, from deserts to rainforests. Lizards, a prominent group within Squamata, often have limbs and can be seen basking in the sun. In contrast, snakes lack limbs and move by slithering. Both lizards and snakes play essential roles in their ecosystems, helping to control insect populations and serving as prey for larger animals.
