Lizards are ectothermic reptiles, meaning they rely on external heat sources to regulate their body temperature. They often bask in the sun to warm up and may seek shade or burrow into the ground to cool down. This behavior helps them maintain optimal body temperature for activities like hunting and digestion. Lizards are also known for their diverse feeding habits. Many are insectivorous, preying on insects like crickets and beetles, while others may eat plants or small animals. Their hunting techniques vary; some use stealth and quick movements, while others may rely on camouflage to ambush their prey.
