What are the structure adaptation of reptiles?

Reptiles have several structural adaptations that enhance their survival. Their scaly skin, made of keratin, minimizes water loss and provides protection against environmental hazards. They possess a three-chambered heart, allowing for efficient circulation, and their lungs are adapted for breathing air, supporting their terrestrial lifestyle. Additionally, many reptiles have specialized limbs and claws for climbing, digging, or swimming, depending on their habitat.
