Both amphibians and reptiles are cold-blooded vertebrates, but they differ in a number of ways. Amphibians are capable of living both on land and in water. They have both lungs and gills to enable breathing in both habitats. They also prefer to live near water to avoid drying out their skin. Amphibian skin is smooth and moist, unlike the dry and scaly skin of reptiles. Amphibians undergo metamorphosis and breathe from their gills until their lungs develop. Amphibians lay eggs on moist ground or in water and their young develop in water. They reproduce by external fertilization. Common examples of amphibians are frogs, salamanders, etc.
Reptiles live on land, reproduce by internal fertilization, lay eggs on the ground and have only lungs. Some examples of reptiles are snakes, lizards, etc. They have dry, scaly skin and do not undergo metamorphosis.
