What type skin reptiles have?

Reptiles have a tough, scaly skin made of keratin, which helps prevent water loss and provides protection from environmental hazards. Their skin is often dry, as opposed to the moist skin found in amphibians, and it can come in various textures and colors, helping with camouflage or thermoregulation. Reptiles periodically shed their skin in a process called ecdysis, allowing for growth and the removal of parasites.
