How are amphibians and reptiles skin similar?

Amphibians and reptiles both have skin that plays a crucial role in their survival, serving as a barrier against environmental factors. Their skin is generally moist and permeable, allowing for the absorption of water and gases, particularly in amphibians. Additionally, both groups can have scales or similar protective structures; reptiles typically have dry, scaly skin, while amphibians often have smooth or warty skin. Despite these differences, both types of skin help in thermoregulation and protection from predators.
