Detailed explanation-1: -What is a pangolin, really? Though many think of them as reptiles, pangolins are actually mammals. They are the only mammals wholly-covered in scales and they use those scales to protect themselves from predators in the wild.

Detailed explanation-2: -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. Almost all reptiles are cold-blooded, and most lay eggs-though some, like the boa constrictor, give birth to live young.

Detailed explanation-3: -In lizards and snakes, the whole skin is covered in overlapping epidermal scales and in turtles and crocodiles in dermal scutes.

Detailed explanation-4: -Reptiles live on land, have scaly skin and lay eggs with shells. They have lungs rather than gills and may or may not have teeth. Some examples of reptiles are turtles, tortoises, lizards, snakes, crocodiles, and dinosaurs (now extinct).
