What are Squamata?
Squamata is a widespread order of reptiles known for their scaly skin and flexible jaws. This order includes two primary subgroups: Lizards and Snakes. Members of Squamata are characterized by their kinetic skulls, which allow for greater mobility, particularly in feeding. They possess overlapping scales, which is a distinctive feature of the group, and are ectothermic, relying on external sources to regulate their body temperature.

Examples of Lizards
Lizards are a diverse group within the Squamata order, known for their four-legged body structure, although some, like snakes, have lost this feature through evolution. They are found in a variety of habitats worldwide and exhibit a wide range of sizes, colors, and adaptations. Common examples include the Green Iguana, Chameleon, and Gecko. Lizards are mostly insectivorous, but some, like the Iguana, are herbivorous.
- Lizards have a four-legged structure but some, like snakes, have evolved loss of limbs.
- Found in diverse habitats worldwide.
- Common examples include Iguanas, Chameleons, and Geckos.
Examples of Snakes
Snakes are legless lizards that have evolved a slender, elongated body, allowing for efficient movement in their environments, whether terrestrial, aquatic, or arboreal. They are known for their ability to consume prey whole, thanks to their highly flexible jaws. Examples of snakes include the Boa Constrictor, Cobra, and Naja (a genus of venomous snakes). Snakes are found on every continent except Antarctica and have adapted to a wide range of ecosystems.
