Adaptation in reptiles:
- Reptiles like snakes and earthworms use their muscles to creep and move. Snakes have special adaptations like scales on their skin that help them glide smoothly on the ground. They move by contracting their muscles in a wave-like motion.
- Animals like house lizards and monitor lizards have clawed toes, which help them grip surfaces and climb easily. Their thin soles help them stick to walls and move without slipping.
- Many reptiles, like garden lizards, can change their body colour to blend in with their surroundings. This helps them hide from predators and catch prey.
- Snakes and other reptiles have scaly, tough skin that protects them from harsh environments and prevents water loss.
