Explanation: 

Detailed explanation-1: -The main difference between reptiles and amphibians is that reptiles are covered in dry scales and scutes, while amphibians have moist skin.

Detailed explanation-2: -Amphibians do not, and their skin is often moist with mucus, which keeps them from drying up. While many amphibians, including frogs, salamanders and caecilians, have smooth skin, most toads have bumpy bodies covered with raised glands, some of which produce toxic secretions. But no amphibians have scales.

Detailed explanation-3: -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-4: -⚡ Quick summary. Reptiles are born with lungs, typically lay their eggs on dry land, and have scaly skin. Most amphibians are born with gills but later develop lungs, typically lay their eggs in water, and have thin, moist skin (without scales).
