Skin

Amphibians have smooth, thin, transparent skin, allowing them to breathe not only on land but also in water. Many of them have warts with different functions and mucous glands that generate mucus, which help to moisten an amphibian’s skin and keep it from drying out. Amphibians, like reptiles, can shed old skin. Some of them even eat it.
The skin of reptiles is covered in scales, like turtles. It’s watertight and plays a huge role in their protection. Unlike amphibians, reptiles can’t secrete mucus through their skin. Many of them shed old skin over the course of their entire lives.
