a toad is a amphibian.
The skin of an amphibian is thin, moist, and permeable, allowing for the exchange of gases and liquids. It lacks scales or feathers and is covered in mucous glands that help keep the skin moist and aid in respiration. The skin also plays a role in thermoregulation and can secrete toxins for defense against predators.
No. Echidnas are mammals, and mammals do not have scales. Echidnas have skin covered by thick fur, and spines growing throughout the thick fur.
Reptiles have waterproof scales so that water doesn't escape from their bodies. It prevents dehydration. Same goes for the egg, it is all designed to keep precious moisture inside.
Reptiles have a body covering of dry, scaly skin. They do not have individual scales as fish do, but the scales (also known as scutes) are joined together to form a seamless outer covering of skin. The scales are made of keratin, the same substance of which human fingernails and hair are made.
Reptiles have dry, scaly skin while amphibians have moist, smooth skin. This difference in skin type helps reptiles to retain moisture and prevent desiccation on land, whereas amphibians rely on their moist skin for oxygen intake and gas exchange.
Lizards are reptiles. While some reptiles may be just as happy (if not happier) in the water as out of it (crocodiles, alligators, turtles, snakes), amphibians are biologically adapted to aquatic living (salamanders, frogs, toads). Among the more striking differences between reptiles and amphibians is their skin; reptiles have tough scales where amphibians do not - amphibians tend to produce a mucous layer to keep their skin moist (slimy).
