Detailed explanation-1: -Reptiles have a reputation that they are “slimy” when we touch and hold them; however, they have dry skin, which has even fewer glands than mammals or amphibians. The main special feature of their skin is that the epidermis is heavily keratinized with a layer, which also prevents water loss.

Detailed explanation-2: -You may not think of their shells as being scaly, but they are! They are complex structures made up of bones and scales that develop from the outer layer of skin. It’s natural body armor!

Detailed explanation-3: -Reptiles are a class of vertebrates made up mostly of snakes, turtles, lizards, and crocodilians. These animals are most easily recognized by their dry, scaly skin.

Detailed explanation-4: -Reptiles have a tough, dry, scaly skin that protects them from predators and allows them to live in dry places by reducing water loss. Reptilian scales are made of keratin, like hair, and found in an overlapping arrangement. This creates a sort of environmental shield for the animal.

Detailed explanation-5: -Reptiles are cold-blooded vertebrates. (Vertebrates have backbones.) They have dry skin covered with scales or bony plates and usually lay soft-shelled eggs.
